General information


M

Conference and exhibition on model-driven development

Engineering for global markets facing worldwide competition is a challenge. Doing more in less time with less hassle is a must. Deadlines are hard and requirements stringent. How do you integrate the various design flows? How to integrate and synchronize mechanics, physics, engineering, electronics and software in an end-to-end toolchain? How do you get more done, with more quality, in a shorter timeframe?

To address these challenges, modeling and simulation are of increasing importance in the product development process. The tooling is advancing fast and approaches physical real-ity. In fact it is possible to skip physical models or prototypes in many cases and develop a product or machine first time right. The tools also increasingly incorporate environments for the different disciplines.

At the Model-Driven Development Day technicians, technical managers and decision mak-ers learn the latest news, share experiences and exchange ideas about organizing and managing their development flows. MDDay offers various in-depth presentation sessions on finite elements, multi-body dynamics, multi-physics development methods and simula-tion as well as presentation tracks on software and system development.

MDDay is the once-a-year quality event to connect disciplines to get you more productive and more successful.

Architecture and MDD: they can’t do without each otherArjen Klomp (NSpyre)Successful MDD projects have one thing in common: they focus on software architecture, and not on MDD. For any software project choosing a proper architecture is a key element to success. This is even more the case for projects that want to apply MDD.

Modeling any design, and especially legacy designs, will quickly run into trouble if you don’t first assess your software architecture on a number of essential properties: did I apply the right abstractions in my design? Are the responsibilities in my sys-tem correctly distributed? Did I clearly separate decision logic from (data processing) algorithms? When either of these properties is not adequately addressed modeling will soon start to become dif-ficult and lead to a process of deep frustration and lack of progress.

In our experience modeling difficulties are the harbinger of architecture problems. But unfortunately in inexperienced teams often the tools and/or methods get the blame rather than an in-herently wrong architecture. In projects where architecture has been given sufficient attention modeling becomes in many cases straightforward and an enabler of success. In these projects the tools and methods are not a source of frustration. Rather, based on a well-defined architecture it is easy to use different kinds of tools for different aspects of the system. For example to design algorithms with tools like Matlab, model supervisory control with the ASD:Suite and defining the data model with UML tools like En-terprise Architect.

This presentation will show different architecture aspects that we have found to be essential to address before you start mod-eling, based on our experiences in model-driven development.

Arjen Klomp has a master’s degree in computer science from the University of Twente. His professional career started with developing data warehousing systems but was soon pursued in software devel-opment for high-tech systems and consumer electronics. Over time his role shifted from pure technical to help customers finding solu-tions, and as a result his responsibilities shifted from a software de-veloper and architect to business development, sales and marketing. In his current role as management consultant he helps customers ad-dress their software development challenges with new and innova-tive solutions to go faster to market with higher quality.

Spray: the quick way to develop visual model editorsKarsten Thoms (Itemis)The Graphiti framework is an Java API-based approach to create highly sophisticated visual editors on top of the GEF framework. Creating editors with Graphiti is fairly simple, but yet repetitive, which makes it a candidate to be supported by the means of mod-el-driven development.

Spray provides DSLs written with XText to describe visual DSL editors against the Graphiti runtime, and code generation (with XTend2) to create the boilerplate code for realizing the implemen-tation. The DSL employs some advanced and interesting usage of XText and XTend.

After a short introduction into basic Graphiti concepts and the motivation to create Spray, I will explain the Spray DSLs and dem-onstrate how to create a fully functional visual editor for a given EMF domain model within minutes.

Karsten Thoms works as a software architect at Itemis, the leading company for applied model-driven software development in Ger-many. He works on customer projects of all sizes and over all life-cycle phases with an emphasis on enterprise Java applications and a special focus on applying model-driven techniques. He is an open source enthusiast and likes to share his experience by participating in projects like Openarchitectureware, Eclipse Modeling or Spray when-ever he can.

Integrating modeling tools and programming toolsJuha-Pekka Tolvanen (Metacase)Traditionally, it has been difficult for development teams to com-bine the use of models and code. As a result, the former are usually thrown away once the implementation has progressed. The reason is partly because of the modeling languages used and partly be-cause of the tools.

Domain-specific modeling languages provide one possible so-lution. They allow raising the level of abstraction beyond program code so that there is no need to round-trip engineer between models and code. This is similar to how the abstraction level raised when we moved from assembler. We did not seek to integrate or reverse engineer assembler and 3GLs. Today any attempt to do so would be regarded as comical by most. Similarly we should

not seek to integrate higher-level models into programming lan-guages used today but use automation to provide the code from high-level models. Domain-specific solutions also offer the possi-bility to integrate with existing legacy code, e.g. in libraries and frameworks, as well as with applied coding standards.

Development tools have also evolved from closed environ-ments to open ones providing various extension approaches and interfaces. In this talk we describe proven ways and best practices to integrate modeling tools and programming tools. The integra-tion ways are demonstrated with various tools, including Eclipse and Visual Studio. The integration among tools goes beyond generating code from the models. It covers automating build pro-cess, debugging in model level, annotating errors in models and test case generation.

Juha-Pekka Tolvanen is the CEO of Metacase. He has been involved in model-driven approaches, metamodeling, and domain-specific modeling languages and tools since 1991. He has acted as a consult-ant worldwide on modeling language and code generator develop-ment. He has authored a book on domain-specific modeling and written over sixty articles for software development magazines and conferences. He holds a PhD in computer science and is an adjunct professor at the University of Jyvaskyla, Finland.

Complementary verification of software components using ASD and UppaalJozef Hooman (Esi)We investigated the complementary usage of two formal methods in industrial software development. We combine a commercial refinement checker (the ASD:Suite of Verum) with an academic verifier (Uppaal) to encompass a larger range of verification pos-sibilities, in response to a request by industrial software develop-ers. In a short time we derived the essential models from a camera protection system (a Fei use case), translated them to Uppaal and by verifying required properties, found some small design errors. In this report we describe the process in detail and discuss briefly the advantages of the complementary verification methods.

Jozef Hooman is a research fellow at the Embedded Systems Institute (Esi) since 2003. He participated in a number of ‘industry-as-lab’ projects on performance, evolvability and reliability with industrial partners Océ, ASML and NXP. Currently he is involved in the Commit

project Allegio with Philips Healthcare on increasing the speed of in-novation by removing faults early in the development process. In ad-dition to his work at Esi, he is a full professor at the Radboud Univer-sity Nijmegen on model-based development of embedded software.

Models for testing versus models for designMachiel van der Bijl (Axini)Philips Healthcare, Axini, Esi and the universities of Delft, Twente, Eindhoven and Nijmegen are working together to develop new in-novative methods for software development in the Commit project Allegio. Its main focus is to speed up software development. The modeling of software components plays a central role in the project.

In this talk we address the use of models for the validation and verification of software. This is an interesting area, because about 40 to 60 percent of the software development time and cost is in testing and integration. We developed tooling and a development process to reduce the testing and integration time, including the optimization of the specification and documentation phases. This should result in a 10 percent productivity gain in the total software development cycle.

We discuss the first results of the project. By popular demand, we will pay attention to the relation between models used for code generation and the models used in the project and how these two strengthen each other. The models for code generation are quite restricted in size, because big models cannot be model-checked. As a result the models need to be split up, which makes it harder to understand and model the functionality as a whole. The models we developed do not suffer from this restriction.

Machiel van der Bijl is founder of Axini, maker of the model-based test tool Axini Testmanager. Testmanager is used internationally in the finance and embedded systems domain for modeling, simulation, testing and certification. Van der Bijl holds an MSc and PhD in com-puter science from the University of Twente and is one of the leading specialists in the application of model-based design and verification.

Model-based testing for cyber-physical systemsJustyna Zander (Simulatedway/Harvard)The ever growing pervasion of software-intensive systems into physical, technical, business and social areas not only consistently increases the number of requirements on system functionality and features, but also puts forward ever stricter demands on system quality, reliability, safety, and usability. For example, cyber-physical systems (CPS), frequently characterized as smart systems, include digital cyber technologies, software, and physical components and are intelligently interacting with other systems across information and physical interfaces. They are expressing an emerging behavior and so, create even more functionalities on the fly. CPS are sensing the external world and they immediately react on the state of the surrounding. Thus, in order to successfully develop such complex systems and to remain competitive on top of that, early and con-tinuous consideration and assurance of system quality is becoming of vital importance.

To achieve effective quality assurance, model-based testing (MBT) has become an essential ingredient. MBT covers a broad spectrum of concepts, including, for example, automatic test gen-eration, test execution, automated test evaluation, test control, and

effective test management. It results in tests that can be utilized in the early design stages and that contribute to highest test coverage, thus providing great value by reducing cost and risk. These observa-tions are a testimony to both the effectiveness and the efficiency of testing that can be derived from model-based approaches with op-portunities for better integration of system and test development.

MBT activities comprise different methods that are best applied complementing one another in order to scale with respect to the size and conceptual complexity of today’s systems. This talk pre-sents model-based testing from a number of different perspectives that combine various aspects of CPS, embedded systems, embed-ded software, their models and their quality assurance. As system integration has become critical to dealing with the complexity of modern systems and, indeed, systems of systems, with software as the universal integration glue, MBT has come to present a persua-sive value proposition in system development.

Justyna Zander is a postdoctoral research scientist at Harvard University and Harvard Humanitarian Initiative Fellow in Cambridge, Massachusetts (since 2009). She is involved in creation of scientific programs and teaching at Gdansk University of Technology in Poland as a visiting professor (since 2011) and at Singularity University in California as a teaching fellow (since 2010). In 2011, she also founded Simulatedway, a consulting company on model-based design and model-based testing, simulation, software quality assurance and rapid prototyping with worldwide operations focus. Before, she was a project manager at the Fraunhofer Institute for Open Communication Systems in Berlin, Germany (2004-2010). She holds a doctorate of engineering science (2008) and a master of science (2005) degrees, both in the field of computer science and electrical engineering from Technical Univer-sity Berlin, a bachelor of science (2004) degree in computer science and a bachelor of science degree in environmental protection and manage-ment from Gdansk University of Technology (2003).

Model-driven engineering of litho scannersWilbert Alberts & Ramon Schiffelers (ASML)ASML is the world’s leading provider of complex lithography sys-tems for the semiconductor industry. Such systems consist of nu-merous control loop systems to control, for instance, the 6-DOF positioning of a 15 kg wafer positioning module with nanometer accuracy at Formula 1 acceleration. This results in tight hard real-time requirements on their implementation.

These control systems are developed according to the control architecture reference model Carm that consists of different layers to describe at different levels of abstraction:1. the control logic in terms of (interconnected) servo networks of

elementary sensor, actuator, and control blocks;2. the (relevant subset of ) execution platform of a litho scanner.Domain-specific languages (DSLs) have been developed covering the layers described in Carm. The models specified using these DSLs form the basis to:

• verify upfront whether the timing requirements are met and to predict the effect of control loop changes and/or platform changes. For this, the models are transformed automatically into formal, executable models for detailed timing analysis;

• generate code that is executed on the litho scanners. For this, code generators have been developed based on model-to-model and model-to-text standards;

• schedule control loop calculations on multi-core execution platforms. For this, during initialization of the litho scanners, the control and execution platform models are transformed by means of model-to-model transformations into a schedul-ing problem, which is solved subsequently.

In this presentation, we will discuss:1. development of the aforementioned DSLs, including their tex-

tual/graphical concrete syntaxes and IDE environments, based on the Eclipse Modeling Framework;

2. analysis based on dedicated analysis models generated from the DSL models;

3. generation of code from the DSL models;4. embedding of this MDE approach in the development process of

the control systems from the litho scanners.

In 1993, Wilbert Alberts graduated in computer graphics at the Eindhoven University of Technology in. After that, he completed the post-master Ooti course. After completing his PhD on the design and implementation of the Chi compiler in 1998, he started at ASML as a software designer and gradually moved into the position of senior software architect. As such he has been responsible for the develop-ment of a number of subsystems and recently for the development of a process control framework. Currently, he is involved in the applica-tion of domain-specific languages and accompanying tooling in the domain of ASML lithography systems.

Ramon Schiffelers received the MSc and PhD degrees from Eind-hoven University of Technology. His PhD project resulted in the hybrid process algebra Chi and accompanying tools. As a post-doctoral re-searcher, he dealt with modeling, analysis and synthesis of supervi-sory controllers for Philips MRI scanners and participated in European projects dealing with the design of the Compositional Interchange Format for hybrid systems. For Cif he introduced domain-specific lan-guage design methods and accompanying tools. In November 2010, he joined ASML, where he is responsible for the development of DSLs and analysis tools to enable an integrated development flow for modeling, analysis and construction of servo control systems for litho scanners.

Safety-critical model-driven design of the world’s first automatically guided tramJulian de Marchi (Altran)Altran propose to present their model-driven development work on the Phileas project. The Phileas project is a challenging, mul-tidisciplinary engineering effort to produce the world’s first auto-matically guided vehicle (AGV) for deployment as a city tram for public transportation. The Phileas vehicle is an omnibus outfitted with an array of special sensors and actuators that allow it to fol-low a prescribed public transport route, picking up and dropping off passengers at stops along the way.

The Altran presentation will cover the following model-driven design elements:• modeling of the Phileas vehicle in Simulink (from the Math-

works);• development of the guidance algorithm in Simulink (from the

Mathworks);

Abstracts

• verification of the guidance algorithm in simulation using Truc-sim (from Mechanical Simulation Corporation);

• verification of the guidance algorithm on the Phileas vehicle us-ing Canoe (from Vector Informatik).

In engineering terms, the Phileas vehicle incorporates a sophisti-cated guidance algorithm that is able to automatically control its trajectory. In order to efficiently design a safe and reliable guid-ance algorithm, the Phileas vehicle itself is extensively modeled in both Simulink and Trucksim. This modeling includes not only the 3D dynamics of the vehicle proper but also all so-called guidance-related adaptations and extensions to the vehicle architecture, such as servo-controlled steering mechanisms and detectors un-derneath the vehicle that sense magnets embedded in the road-way for trajectory-tracking purposes, as well as every other guid-ance system hardware component needed to control the vehicle’s motion safely in real time.

The model-driven approach afforded by these tools reduces development time and mitigates big-bang integration risk by permitting extensive simulation of actual vehicle behaviour before final testing of the Phileas on the road is even possible.

Julian de Marchi is technical manager on the Phileas project for the development of an autonomously guided omnibus designed for pub-lic transport. As lead consultant at Altran he has worked as systems architect for Philips Medical Systems, Philips Consumer Lifestyle, Ne-opost and other clients. He holds a PhD in mechatronics and during fifteen years of industry experience has worked in both Europe and the US on several cutting-edge projects in a broad variety of high-technology sectors.

Model-based controller design applied to hybrid trucksRudolf Huisman (Daf )The main task of an energy management strategy in a hybrid vehi-cle is to determine the power split of the total power demand into power requests to the internal combustion engine and a secondary motor/generator (e.g. an electro motor). In a knowledge worker pro-ject together with the TUE and Tegema, we applied three different model-based controller design techniques in the development of an energy management strategy. These techniques are: optimal control, predictive control and dynamic programming. Based on simula-tions, a comparison of the resulting energy management strategies is made, focusing on performance, robustness, real-time possibility,

tuning effort and extensibility (e.g. with preview information). In addition, the strategies are compared to a heuristic strategy, similar to those typically used in hybrid vehicles such as the Toyota Prius.

Rudolf Huisman received his MSc and PhD degrees from the Eind-hoven University of Technology, in 1990 and 1994 respectively. Since 1995 he works at Daf Trucks in the Product Development department in the area of electronic control systems. His main research activities concern the specification, design and rapid prototyping of controllers for (semi-)active suspensions, electronic braking systems, vehicle stability systems and powertrain control systems.

The value of an executable architectureArjen van de Wetering (IBM Rational)Developing multidisciplinary systems can be a difficult task. Main-taining the consistency throughout the development cycle and across the disciplines is one of the many challenges that has to be addressed. We will explain in this presentation and live demo how the creation of an executable architecture can help to maintain an inherent consistency between the artifacts created by the differ-ent teams. We will show how to create such an architecture using SysML and graphical simulation and how to assure behavioral correctness by continuous validation throughout the process. This approach guarantees a higher quality project that meets time-to-market pressures while handling increased architectural complex-ity and improving productivity.

We will present this approach by taking you through the archi-tectural workflow using the IBM Rational Rhapsody solution as a model-driven development environment for real-time or embedded systems and software. The demo will cover the following topics:• Requirements traceability at a model level in order to show

change impact for a true integrated requirements solution.• Creation of an executable multidisciplinary architectural model

applying standard SysML.• Testing is an integral part of a model-driven approach and this

will also be demonstrated by simulation and test capabilities built into the environment.

After the demo we will discuss advantages of this approach and how the resulting architecture can be handed over to the develop-ment teams that cover the different disciplines (mechanical, elec-trical, software, chemical, etcetera).

Since 1988 Arjen van de Wetering has been working in the techni-cal systems and software engineering domains as a an engineer, a consultant and a manager. He was responsible for developing real-time and embedded software, technical algorithms, machine control systems and intelligent products. He has always had a focus on finding ways to improve how things are done and adopted new methods and technologies such as object orientation, incremental processes, design patterns, component-based development, Agile methods and model-driven development. He has also found his way into management processes such as requirement management, pro-ject management, configuration and change management and test management. He strongly believes that processes such as XP, Scrum, Harmony and Rup have great value when applied with care.

Model-driven warehouse developmentJacques Verriet (Esi) & Bruno van Wijngaarden (Vanderlande)Warehouses are facilities that enable the efficient distribution of goods from producers to consumers. A warehouse’s operations are coordi-nated by a warehouse management and control system (WMCS). Al-though there are clear similarities between customer warehouse pro-cesses, each customer has its own delivery requirements. This makes controlling the operations in a warehouse a large challenge.

In order to deal with this challenge in a manageable way, Van-derlande and the Embedded Systems Institute are developing a model-driven approach for WMCS development. Our model-driven WMCS development aims at reusability of WMCS functionality by adopting a highly modular approach. We distinguish two common warehousing roles: planning and scheduling. Planning involves the allocation of resources to tasks and scheduling coordinates the se-quencing of tasks.

We have defined a reference architecture that distinguishes these roles: it contains generic planning and scheduling components that communicate via standardized interaction protocols. These compo-nents and protocols capture the similarities of different warehouse processes. To obtain the necessary flexibility required to capture customer-specific requirements, the components and the interac-tion protocols are parameterized. Both can be configured to behave as needed to fulfil the customer’s requirements. The components are configured by equipment characteristics and their communication interfaces and interaction protocols. The configuration of the inter-action protocols involves specifying customer-specific decision rules guiding components’ behaviour.

We will show how our reference architecture can be used to con-figure a WMCS. One can build a WMCS that resembles the underlying warehouse equipment: warehouse zones are represented by planning and scheduling components that are configured using zone character-istics. The components’ communication interfaces resemble the ware-house’s transportation system. Customer-specific requirements are captured by configuring the components’ interaction protocols.

Jacques Verriet received his MSc degree in computer science from the Radboud University in Nijmegen in 1994. After graduating, he worked as a research assistant in the department of Information and Computing Sciences at Utrecht University. His research on multi-pro-cessor scheduling concluded in June 1998 with a PhD degree. During 1998 and 1999, he was a consultant for the Centre of Quantitative Methods in Eindhoven, focusing on vehicle routing and shortest path problems. He then moved to Siemens VDO Automotive in Eind-hoven, working as a researcher/software engineer on route planning and positioning for car navigation systems. In September 2006 he started as a research fellow at the Embedded Systems Institute. At Esi his focus is on system modeling, model-driven development and (de-centralized) system-level control.

Bruno van Wijngaarden received his MSc degree in electrical en-gineering from the Eindhoven University of Technology in 1986. After graduating he worked as a system engineer at Vanderlande designing material handling systems for customer projects. From 1991 till 2000 he worked as a system engineer and project manager at Xerox on a range of projects, automating supply chain and warehouse processes. In 2000 he returned to Vanderlande working as a system architect on market analysis, product development and knowledge management. He is currently working on development of system architecture, model-based design and on the development of AGV systems.

Connecting disciplines through co-simulationChristian Kleijn (Controllab)One of the greatest challenges in developing dependable embed-ded systems is bridging the gap between the engineering disci-plines involved. The Destecs project (Design Support and Tooling for Embedded Control Software) tries to bridge this gap by devel-oping methods and tools that combine continuous time system models with discrete event controller models through co-simu-lation. The project aims to support multidisciplinary modeling, including modeling of faults and fault tolerance mechanisms. The analysis of these effects at every stage in a design process will help to build more dependable real-time embedded systems.

This presentation is meant for innovators and developers of embedded systems. It will introduce co-modeling and co-simula-tion technology developed in the Destecs project and give insights into the experience of developers using the methods and tools in the transport, space, defense and industrial automation domains. In 2010, the members of the Destecs Industry Follow Group were asked to propose three challenge problems for the methods and tools developers. During this presentation the outcomes of these challenges will be presented, giving a insight into what is achiev-able using co-modeling and co-simulation.

Christian Kleijn is the managing director of Controllab Products. He studied electrical engineering and mechanical engineering at the University of Twente. After his graduation in 1996 he founded the company Controllab, the producer of the well-known modeling and simulation package 20-Sim. Kleijn has been active as a consultant on mechatronics and control systems. In the Destecs project he is studying the application of model-based design techniques for em-bedded systems design.

Multiphysics, some industrial examplesHelger van Halewijn (Physixfactor)In this presentation some examples, from water management to molding technology, will be given what multiphysics simulations can offer for the industry in terms of cost saving and reduction of development time. Some words will be spent on the history of multiphysics and what the near future might bring us.

Helger van Halewijn studied physics at the Universiteit Utrecht from 1979 to 1986, specializing in astronomy. He started his professional

career at Element Six. There, he worked from 1986 to 1994, first as a scientific engineer and later as R&D manager. The same function he subsequently held at Drukker International (from 1989 to 1995), Esteves-PDT (from 1996 to 2005) and Diamond Tools Group (also from 1996 to 2005). Since 2004 he is owner of his own company Physixfactor, where he does consultancy of mechanical, heat transfer and flow simulations. Since 2007 he is also lecturer finite element methods, multiphysics and CFD at Fontys.

More efficient machines through model-based designWim Symens (FMTC)During the last years, the ecological footprint has more and more come forward as an important design criterion for machines. On the one hand, there are the increasing energy prices, which influence a machine’s total cost of ownership considerably. On the other hand, there is a growing ecological awareness, which leads amongst oth-er things to more stringent energy consumption regulations for the manufacturing field, and the machinery sector in particular.

Niet minder dan 66% van de producten die vorig jaar zijn ontwikkeld, bevatte op de een of andere manier ingebouwde informatietechnologie. We leven in een wereld van slimmere producten en dat levert ons allemaal tal van voordelen op. Plus een heleboel interactief plezier!

Maar wat betekent dit voor de makers van deze producten? Wat zijn voor hen de implicaties van het inbouwen van computertechnologie in dingen die we nooit zullen beschouwen als computers, zoals telefoons, auto’s, huishoudelijke apparaten, kleding en medische apparatuur?

Eén ding is duidelijk: software wordt voor elk bedrijf een strategische business bedrijfsmiddel. De makers van slimmere producten moeten alleen net zo bedreven zien te worden in complexe systeemintegratie en softwareontwikkeling als ze al waren in conventionele ontwerp-en productieprocessen.

Deze verschuiving is diepgaand. En urgent. Wat moet een bedrijf bijvoorbeeld doen om software te integreren in een complexe, voortdurend uitdijende supply chain, terwijl steeds meer componenten afkomstig zijn van diverse locaties, worden geleverd met ingebouwde software en worden geassembleerd in steeds wisselende combinaties?

Toonaangevende bedrijven in de luchtvaartindustrie pakken deze problemen aan door de voortdurend veranderende eisen voor ontwerp en fabricage op een volkomen andere manier te benaderen.Tegelijkertijd worden bedrijven bij hun product-ontwikkeling geconfronteerd met mechanische, elektronische en softwarematige technieken die hun intrede doen in het ontwerpproces. Dit vraagt om een grotere mate van interoperabiliteit. Zo heeft BMW zijn engineeringsprocessen gemodelleerd naar het voorbeeld van grote software-leveranciers. De test-en productiekosten konden daardoor drastisch worden verlaagd. Fabrikanten die software systemen of virtual prototyping hebben opgenomen in hun bedrijfsvoering, presteren over het algemeen uitstekend: ze halen 90% van hun productdeadlines en blijven in 87% van de gevallen binnen het budget.

Dankzij slimmere manieren om producten te maken, kan het creeren van producten in de 21e eeuw dezelfde stormachtige ontwikkeling doormaken als massaproductie in de 20e eeuw.

We kunnen de wereld slimmer maken. Kom naaribm.com/smartproducts/nl en kijk wat andere bedrijvendoen.

Industry is therefore looking for methods to assess a machine’s energy consumption already during the design phase. However, for complex machines the energetic interaction between various components in the machine has to be considered, which compli-cates dealing with energy consumption early in the design.

Model-based design offers a way to tackle the eco-efficient design issue for complex machines in a systematic way. This pre-sentation will show how by the development of numerical models the energy consumption of the badminton robot that is designed by FMTC could be reduced with tens of percents. However, a barrier for applying this approach during machine design is the availability of good numerical models of the components used, especially for the components that are acquired from suppliers. A possible scenario to solve this issue and get information on the energy consumption of acquired products will be proposed during the presentation.

Wim Symens graduated in 1999 from the Katholieke Universiteit Leuven, Belgium, as a mechanical engineer, option mechatronics and obtained the PhD degree in mechanical engineering from the same university in 2004. His PhD research was dealing with ‘Motion and vibration control of mechatronic systems with variable configura-tion and local non-linear friction’. After that, he started at Flanders’ Mechatronics Technology Centre (FMTC), where he was responsible for various research programs targeting productivity improvements of machines. His general research interests include modeling, control and design of mechatronic systems. Most of his current activities are focused on finding ways to reduce energy consumption of electro-mechanical drive trains for production machines.

Design and optimization of ultrafast ALD processes by means of modeling Adriaan Lankhorst (TNO)Atomic layer deposition (ALD) is a deposition method capable of producing very thin conformal layers with control of film thick-ness and composition at the atomic level. However, due to its very low deposition rates (tenths of Å/s) the method is limited to only a few industrial applications. Recently, there has been a renewed interest in ALD, showing that silicon solar cell efficiency can be drastically increased by applying thin Al2O3 films by ALD for surface passivation. This is an important breakthrough for high-efficiency solar cell production, provided that these ALD quality passivation layers can be deposited by a cost-effective technique, meeting in-dustrial scale throughput demands.

In conventional time-separated ALD, the deposition reaction is divided in two time-sequenced self-limiting half-reactions, each one being separated by purge steps. In the case of Al2O3, one de-position cycle includes a dose of an aluminum precursor (mostly trimethyl aluminum, TMA), followed by a purge step to remove ex-cess precursor and reactants, a subsequent oxidation step (mostly H2O, O2 or O3) and, finally, another purge step. The entire process typically takes place at elevated temperatures (thermal ALD) and at low reactor pressure. The layer growth rate during such a cycle, or growth per cycle (GPC), is typically 1 Å/cycle. Thus to obtain thicker films, the cycles have to be repeated many times, leading to a process time of 100 min to obtain a layer of 100 nm thickness.

At TNO a new ALD concept was developed, based on spatially separated half-reactions, instead of time-separated, combined

with gas-bearing technology. In this concept, the reactor has separate zones exposing the precursors one by one to a substrate that moves relative to the reactor. Between and around the reac-tion zones, shields of inert gas separate the precursor flows. When designed and operated properly in terms of dimensions, pressures and flow rates, excellent cross-diffusion barrier properties are obtained and the gas shields can act as gas bearings, supporting the substrate and facilitating virtually frictionless movement be-tween reactor and substrate. This concept allows for the deposi-tion of high-quality Al2O3 passivation layers with deposition rates as high as a few nanometers per second. Thus, ALD with industrial throughput values becomes feasible.

In the spatially-separated ALD process, many different interact-ing functional requirements have to be met, such as:• high layer growth rate;• no cross-mixing of precursors and reactants;• no reactor fouling;• no escape of precursors and reactants to the environment;• proper gas-bearing properties.Due to the complexity of the physics and chemistry involved, mod-eling has proved to be an indispensable tool. For the design of the ALD reactors and for the definition of an optimal set of process con-ditions, modeling – from the level of estimating the relevant time scales to detailed 3D CFD modeling – has shown to have been of vital importance, shortening the development time considerably.

Some examples of how modeling has enabled the successful development of spatially separated ALD processes and how it has assisted in optimizing both reactor design and process conditions will be shown in the presentation.

Adriaan Lankhorst received his MSc in applied physics in 1985 at the Delft University of Technology and obtained his doctoral degree in 1991. In 1990 he started working at TNO as a process physicist, managing and executing projects involving complex physics and chemistry, developing and applying computational fluid dynamics (CFD) models. He is specialized in high-temperature processes such as glass melting, combustion, turbulence, radiative heat transfer and multi-crystalline silicon crystallization processes. Other fields of in-terest and experience are related to chemically reacting flows such as chemical vapor deposition (CVD) and atomic layer deposition (ALD) processes. Since this year he is manager R&D at Celsian Glass & Solar, a TNO spin-off company based in Eindhoven. The mission of Celsian is to become a world player as technology and innovation provider in the fields of process optimization, product innovation and process control for glass and solar PV industries.

Design rules for printingMarco Ezendam (Reden)The printing process plays an important role in digital manufac-turing. When developing a new digital manufacturing application chances are high that one or more phases in the printing process will form a challenge. Insight in the printing process is a require-ment to overcome these challenges and develop a robust printing process and application. Simulating the phases of the printing pro-cess will provide the necessary insight at an early stage of the de-velopment process. An overview will be presented of simulations conducted on different phases of the printing process.

When making new products it is all about the building blocks and the assembly process. The building blocks are defining the po-

tential of the product while the assembly process defines the utiliza-tion of the potential. This is not different when looking at a printer. The building blocks, the droplets, are creating a huge potential due to the fact that they are small and can in theory be of any material e.g. polymers, tissue and molten metals. The accuracy of positioning the droplets in space and time (assembly) and how one can control negative side effects determines a large part of the product quality.

In order to fully utilize the potential of the printing process more understanding and better prediction of droplet behavior during flight and impact is needed. Also the behavior of the sub-strate due to droplet depositioning (for example local temperature changes and deformation due to absorption) is of interest, since this influences the precision of the jetting process.

Modeling is a good way of understanding the phenomena that drive the different stages of the printing process. Also the capabil-ity to predict the behavior of the droplet and substrate is of high value. In this presentation the focus will be on drop-on-demand piezo inkjet printing (PIJ) of water-based ink. However these mod-els can form a basis for future research to polymer, molten metal and tissue or any other printing process.

Marco Ezendam started his education in 1982 at the HTS Hilversum, direction fine mechanics. After his graduation in 1986 he went to the University of Twente, where he obtained his MSc in mechanical en-gineering in 1990. He started his professional career as founder and co-director of Demcon. In 1995 he founded the Technodome holding, with subsidiaries Reden, Baat, Noeton and Randzaak (35 FTE). Since then he is CEO of Reden (Modeling & Simulation).

Simulation in mechatronics and digital powerPeter van Duijsen (Simulation Research)The design of an electrical drive once used to be connecting a sim-ple DC motor. However, today’s designs are far more sophisticated. Electric drives in hybrid electric vehicles and servo drives in robot-ics and industrial automation require a mostly complicated design with many functions and optimized in response and efficiency. At the design stage, simulation is an important tool. It not only gives numerical information, but also insight in functionality, or some-times even more important, it can show the origin of failure.

The presentation discusses the levels of modeling required for electrical drive systems. Discussed are: modeling of the complete electric drive in a mechatronic system and electric vehicles, the system optimization and code generation of embedded systems, the detailed FEM calculations for electric machines and single-phase actuators and 3D multibody simulations. Combining these different models in one system simulation is the common thread in this presentation. The emphasis is on computational methods and models used during the conceptual design, detailed compo-nent simulation as well as the generation of control code for the final embedded implementation.

In the presentation the multilevel multiphysics modeling method will be discussed. The multilevel simulation allows the co-simulation of various techniques such as electronics, electrical machines, me-chanical loads and control in one combined simulation environment.

For a conceptual design stage at the low-level system simulation, functionality is an important simulation result. The optimization of the design for efficiency, reliability and accuracy is carried out on a higher circuit level with the detailed models. On the highest compo-nent level, detailed models can be developed in FEM and multibody

simulation tools that are integrated into the system or circuit-level simulation. Case studies that are discussed include the drive train of hybrid electrical vehicles, the sensorless control of servo drives and the generation of embedded C code for microcontrollers.

Peter van Duijsen has worked with computer simulation and power electronics for nearly 25 years. After receiving his masters in electri-cal engineering, and working at the Technical University of Delft, he founded Simulation Research and developed the simulation program Caspoc.

Modeling of magneto-mechanical coupling in MRI scannersMartijn Termeer (Philips Healthcare)MRI scanners operate with a strong magnetic field. This field is generated by superconducting coils, cooled with liquid helium at 4 K. These coils are mounted in a cylindrical structure of metal vessels, in short called the magnet. To make images a gradient coil generates time and space-varying gradient fields in the patient body. Large currents (order of 1000 A) switching in the kHz range flow through the gradient coil. The gradient fields also propagate in the magnet structure, generating Eddy currents. This leads to

heat dissipation and (because of the large background field via Lorentz forces) to vibrations. Lorentz forces also act directly on the large currents in the gradient coil, which starts to vibrate on its own. This excites the magnet structure via mechanical and acous-tic coupling. Vibrating metal in an inhomogeneous background magnetic field generates Eddy currents. Again Lorentz forces act on these currents, leading to vibrations, et cetera. An unwanted effect of the Eddy currents in the superconducting magnet struc-ture is heat dissipation. At temperatures of 4 K a small amount of heat will increase temperatures (metal heat capacity is very low at 4 K). This can lead to Helium evaporation, or in worst case, to an abrupt ending superconductivity, leading to a so-called quench. Another unwanted effect of the vibrations is acoustic noise.

At Philips Healthcare we model these magneto-mechanical coupling effects using Ansys Multiphysics. With these models we optimize our magnet and gradient coil designs, aiming for less heat dissipation, less Helium consumption, and robustness for quenches. In this presentation we will explain the magneto-me-chanical coupling phenomena in MRI scanners and the way we use multiphysics FE models in the development process.

Martijn Termeer graduated in mechanical engineering at Eindhoven University of Technology in 1997. He worked in the field of structural acoustics, dynamics and precision mechanics at TNO from 1997 till

2007. Since 2007 he works at Philips Healthcare MR hardware devel-opment in Best as senior mechanical expert. Here he works on acous-tics, vibrations and general mechanics of MRI scanners. Modeling the multi-physics interaction between the superconductive magnet and the gradient coil is a recent topic of interest.

Designing the lightest Formula Student race car in the worldMax Wink & Reinier Alberda (Formula Student Team Delft)The Delft University of Technology Racing Team is one of the top teams in the international design competition Formula Student. Team manager Max Wink and FEA specialist Reinier Alberda will elaborate on how the DUT Racing Team has built the lightest and the most reliable Formula Student race cars in the world for over five years. The Delft team designs by the statement: if it does not break after reaching the finish line, it was too heavy.

Max Wink and Reinier Alberda are both students at the TU Delft and full-time involved with DUT Racing. They both put a stop on their studies applied physics and aerospace engineering for half a year and focus fully on getting the twelfth car of the team to the top of the Formula Student Electric competition. Wink is the team leader of an engineering team of over seventy TU Delft students and Alberda has had an internship at Advanced Lightweight Engineering, a com-pany specialized on finite element analysis using Abaqus for half a year. With the experience he gained during his internship Alberda has designed and optimized the structure of this years racing car.

Optimized design and realization of an over-actuated lightweight 450 mm wafer chuckRonald Faassen (MI-Partners)Wafers with a diameter of 450 mm are one of the future challeng-es for the semiconductor manufacturing industry. The increased wafer size leads to an increased size of the positioning stages and chucks. Because of positioning and throughput demands, the wafer chuck tends to increase significantly in thickness and mass, which in its turn leads to larger and heavier actuators. An alter-native is to have a lightweight chuck and use over-actuation. This means that more actuators are used than the unconstrained de-grees of freedom. In order to optimize the geometry in combina-tion with the proper location of the actuators, a FEM optimization has been performed at MI-Partners. The geometry was optimized such that the first five low-frequency eigenmodes are not excited with the actuators. The system has also been built. From the ex-periments is was found that, compared to conventional control, the bandwidth of the chuck could be increased from 50 to 100 Hz, without adding much complexity.

Ronald Faassen received his MSc in mechanical engineering in 2002 from the TU Eindhoven. He received his PhD in mechanical engineer-ing in the Dynamics and Control group of Henk Nijmeijer. The sub-ject of the PhD thesis was the modeling and control of chatter (an instability phenomenon) in milling. After completing his PhD, he worked for TMC Mechatronics, where the did various projects in the field of dynamics and control for Philips Apptech, AMSL Research and MI-Partners. Currently he works with MI-Partners as a mechatronic system architect.

Model-based design of a 6 DOF active vibration isolation platformMaikel Bruin (Mecal)In the field of mechatronics the natural modes of a servo system will limit the performance, speed and accuracy of the system. In the design phase of the hardware it is therefore necessary to be able to calculate the natural modes. This can easily be done using finite el-ement software. However, for complex structures it is often difficult to understand the nature of these modes, which is essential when the design intent is, for example, to maximize performance.

Mecal has developed a technology, based on the finite element method, that is able to determine the nature of the natural modes in an unambiguous manner; it characterizes the dominant mass and dominant stiffness of each natural mode by means of quanti-tive figures. This allows the engineer to redesign the hardware in the most effective way, which leads to a shorter design phase and also a better performance.

This technology was used to design several components of the 6 degrees of freedom (DOF) active vibration isolation platform developed by Mecal and TNO, called Hummingbird. This platform is able to reduce floor vibrations as well as disturbance forces caused by machine movement in 6 DOF, ranging from very low to high frequencies.

Maikel Bruin studied mechanical engineering at the University of Twente from 1995 to 2001. During his final project at Mecal he inves-tigated the effectiveness of a passive damper to reduce the vibrations of wind turbines. After his study he started working at the wind tur-bine department of Mecal. Here, he performed fatigue stress calcula-tions on highly stressed components like the hub, machine frame and gearbox. In 2005 he switched to the semicon product development department of Mecal. For several years he worked in close cooperation with the mechanical development staff of ASML, mainly on the wafer stage. During this period he started his specialization in the field of

dynamics, both theoretical and experimental. After the design phase of a specific sub-system, in which he was responsible for the stiffness, strength and dynamical behavior, he often performed the validity checks using experimental vibration techniques. It is always a cheer-ful moment to get confirmed that the experimental results match with the theoretical models. The past two years he worked on several mechatronic product development projects that were completely car-ried out by Mecal, from specification to delivery.

Finite element modeling of traditional and innovative biomedical stentsDavide Fugazza (Ansys)In this work we present the results of a finite element analysis, entirely set within the Ansys workbench environment, performed on a biomedical stainless steel stent. A stent is a small tube in-serted into a blood vessel partially occluded by a plaque which is aimed at restoring its original diameter and then re-establish a correct blood flow. It is deployed in three steps: first, the stent is mounted on a deflated rubber balloon which is folded around a catheter; the surgeon then positions the balloon-stent system in the problematic area of the blood vessel and inflates the balloon making the stent eventually expand against the interior wall of the blood vessel; last, the balloon is deflated and removed from the blood vessel. From a computational point of view, we consider two deformation stages: the radial expansion of the stent and the recoil which occurs when deflating the balloon. We focus on the stent behavior only and the balloon will be considered as a rigid cylinder to which we apply target displacements. Upon calcula-tion of stresses after radial expansion as well as residual stresses and plastic strains after recoil we investigate the possibility of us-ing innovative materials such as shape-memory alloys in place of traditional ones.

Davide Fugazza received his Laurea degree (July 2000) cum laude in civil engineering from the University of Pavia, Italy, and his inter-national MSc and PhD degrees (in June 2003 and December 2005 respectively) in earthquake engineering from the European School for Advanced Studies in Reduction of Seismic Risk at the University of Pavia as well. Between 2004 and 2005 he spent approximately one year as a visiting research engineer at the Georgia Institute of Tech-nology (Atlanta, USA) and in June 2005 he was recipient of the Young Researcher Fellowship Award in computational mechanics awarded by the Massachusetts Institute of Technology (Cambridge, USA). After graduation he has earned a five years experience as an application engineer in the field of numerical simulations, with an extensive use of finite element packages for consulting activities, research projects

and training classes. Since June 2011 he has been working for Ansys Belgium as a customer and sales support engineer for mechanical-related topics.

How to implement physical design in the design processJacob Vlasma (Viro)Viro is a multi disciplinary engineering company with over 500 en-gineers. The core business is engineering and project management in the disciplines mechanical engineering, engineering analysis, electrical engineering, industrial automation and construction and architecture. The strength of Viro lies in the delivery of complete so-lutions by means of a decisive and integrated approach.

When you look at the term computer-aided engineering (CAE) you can see that it stands for more than just simulation. In practice however this is often how structural or physical analysis engineers are approached. This is unfortunate because they are generally highly trained engineers who can contribute much more than just simulation and validation. You have to involve engineering analy-sis from the start to the end at any design process where physical aspects (temperature, strength, stability, fatigue, et cetera) of the design come to play.

During his presentation I will talk about how Viro implements CAE and in more detail how they use FEA in their design process. I will also try to clarify what knowledge and experience you need in order to be able to perform analysis with accurate results. This is followed up by project examples which also show the advantage of early involvement of engineering analysis.

Jacob Vlasma studied mechanical engineering at the MTS from 1994 to 1998 and at the HTS from 1998 to 2001, both in Leeuwarden. In 2004 he obtained his master’s degree mechanical engineering at the University of Twente, with a specialization in structural dynamics and acoustics. After his graduation he performed research in optimization of the driving signal of an ultrasonic transducer using a genetic algo-rithm. In 2005 he started working at Viro in Hengelo at the department Engineering Analysis, becoming department manager in 2009.

Drawbacks of FEM toolingEmilia Motoasca & Victor Klymko (TU Eindhoven)Finite element method is a popular and powerful approach to prob-lems in electromechanics, acoustics, electricity, magnetism and other fields. A researcher often has to deal with multidisciplinary projects where multiphysics simulations are needed to describe and understand the nature of phenomena and to be able to design realistic devices. For example in applications involving deform-able objects like in electromagnetic forming or piezoelectric energy harvesting multiphysics, simulations are needed to completely un-derstand the non-linear electromagnetic, thermal and mechanical behavior of a device.

Powerful computational tools such as Comsol provide the user with a possibility to include several physical phenomena in the

numerical model and analyze them together. However, a numerical solution is based on discretization of space and time as well as polynomial approximation of the fields in homogeneous domains. This sets the limits on the accuracy of the results and on the com-putation time required for the calculation of for the model. A user has to choose wisely between the required precision and the avail-able computational resources in order to obtain the desired results. These choices will be illustrated using Comsol to solve multiphysics problems that involve electromagnetics, acoustics, mechanics and piezoelectricity.

Emilia Motoasca was born in Romania in 1971. She obtained a MSc degree in electrical engineering from the Transilvania University of Brasov in 1996. Between 1996 and 1999 she has been a research as-sistant at the faculty of Electrical Engineering, Transilvania University of Brasov, Romania. From 1999 to 2003 she has been a PhD student at Delft University of Technology, faculty of Information, Technology and Systems with the Laboratory of Electromagnetic Research. Between 2003 and 2009 Motoasca has worked as postdoctoral researcher and later on as assistant professor at the Eindhoven University of Technol-ogy, faculty of Electrical Engineering with the chair Electromagnetics. Since 2010 she is assistant professor with the group of Electrome-chanics and Power Electronics with strong interests in numerical and analytical methods for electromagnetic field calculations in electro-mechanical applications, electrodynamics of deformable solids, bio-medical applications of (micro)sensors and actuators including robot-ics and neurostimulation devices.

Victor Klymko was born in the Ukraine in 1974. He graduated from Kharkiv State University in 1996 with the university degree in radio-physics and electronics. In 2002 he moved to the United States and became a graduate research assistant at the University of Mississippi, where he later received his MSc in electrical engineering (2004) and PhD in solid-state physics (2009). After graduation, he worked as a visiting instructor and then as a visiting assistant professor of physics at the University of Mississippi. In 2012, he joined the TUE as a post-doctoral researcher. His research is focused on utilizing piezoelectric materials for vibration energy harvesting, microsensors and actua-tors, and development of new piezoelectric transformers.

Dynamic error budgetingThe performance of precision machines is limited by the disturbances that act on these machines. These disturbances are mostly of a stochastic nature. Dynamic error budgeting (DEB) is a method that enables engineers to calculate the performance degradation as a result of these disturbances. The advantage of this method is the ability to show the effects that individual disturbances have on the total output of the machine, and optimize the design accordingly.

The application of DEB so far was limited by the large amount of complex calculations that were required. The software package 20-sim breaks this barrier by introducing a dynamic error budgeting tool that automates these calculations. In this workshop you will use 20-sim and work with the dynamic error budgeting toolbox. You will learn that that you only have to concentrate on the specification of the disturbances, and use the toolbox to calculate the resulting machine performance. This will enable you to do quick iterations to find optimal machine designs.

Please bring your own laptop (Windows XP or higher) because you will get a workshop license of 20-sim with one month validity. Most of the workshop (80 percent) is spent working with 20-sim on exercises and cases.

Requirements management in plain Dutch or English: bridge the gap between marketing and R&DRequirements management and system flow modeling is an area that is quickly gaining interest and importance in industry and research. This is due to the impact it has on the success of projects. As Capers Jones concluded some 31 percent of all projects fail due to poor require-ments. USoft offers you the possibility of using natural language to avoid this. Modeling requirements and expectations in plain language, simulating process and system flow up front saves a lot of time and trouble fixing problems later on in the project. Bridging the gap between R&D and marketing/product management makes your life as an architect or (test) engineer a lot more pleasant.

The goal of this workshop is to let you experience the power of natural language for developing high-tech systems, both hardware/elec-tronics and software. Offering you the possibility to test it live, and get a clear understanding of how this makes your work easier and more successful. For example by generating functional documentation directly from the requirements, saving you a great deal of work on docu-mentation, or direct coupling between validation testing and customer-approved requirements, resulting in less time spent re-specifying required behavior, and higher quality testing.

Today, about 425,000 IBMers around the world invent and integrate hardware, software and services to enable forward-thinking enterprises, in-stitutions and people everywhere to succeed on a smarter planet.

Rational software helps companies drive greater value from their software investments and deliver innovative products and services. It enables organizations to:• deliver software at the speed of business demands;• build smarter, innovative, high-quality systems and products;• lower the total cost of multiplatform applications and applica-

tion development.

Avoid and manage complexity that slows down creativity, pro-ductivity & quality! Organizations that use an integrated de-velopment process are more nimble and find errors earlier in the process when they’re less expensive to fix. When the mar-ketplace or requirements change, a well-connected team can modify products faster and with fewer setbacks.

IBM provides the Jazz platform, the industry’s most compre-hensive, open standards software delivery platform, providing a highly collaborative, productive and transparent software devel-opment environment that transforms software engineering and systems delivery across the life cycle.

USoft is an independent Dutch software vendor that is well known for its natural language-based requirements and process modeling tool URequire Studio, and its business rules and pro-cess engines URule and UProcess. The use of natural language allows you to communicate requirements details between technical and business people in plain Dutch or English, even for the most complex systems and processes. Bridging this com-munication gap is vital, as according to industry research some 31 percent of all projects fail due to incomplete and inconsist-ent requirements. USoft enables you to capture the whole scope

of the project: from the ergonomically designed casing to the deepest software drivers and algorithms. Current customers in-clude Philips, KLM, KPN, ITV, Aker Kvaerner, Molina Healthcare and Eurocontrol.

Reden: driven, innovative and creativeReden (Research Development the Netherlands) is an ambitious, innovative and creative engineering company that excels in simulation-driven product development in many different sec-tors. We support our clients in achieving a breakthrough in their product development. Based on our simulation models we offer product developers better understanding of the relationship between product design en performance. We make, in other words, performance predictable.

Knowledge rulesModels lead us, in addition to understanding the functioning of the product, to new knowledge rules (a knowledge rule says something about the relationship between design parameters and performance). In organizations a multiplicity of knowledge rules exist (tables, formulas, facts of experience, etc.). For engi-neers it is necessary to secure the knowledge in a usable form. Reden has developed a virtual engineer for that called MrReves!
