BUSINESS CASE? VALUE MODELLING

![Page 8: INTEROPERABILITY CHALLENGES FOR CONTEXT AWARE … · Prince Singh . Marten van Sinderen . BDEI@IWEI Workshop .

Mutual beneficial value exchanges imply co-operation between actors, based on trust, willingness to share, and ability to interoperate
Different actors have to work together, e.g. planning and delivering a shipment by the 4PL orders from customers offers from LSPs/carriers context information from data providers assigments to LSPs/carriers etc.

Strategic interoperability is concerned with the responsibilities that partners assume, and whether they live up to these responsibilities, in accordance to expectations/agreements and in line with business goals Financial aspects – division of profit/loss among partners. SLAs – common understanding on the quality and content of the
service(s) each partner provides or consumes Security interoperability is not confined to one layer, but requirements on
CIA stem from strategic and business layer Data sharing policy, e.g. an LSP should not see the status of
resources of another LSP if not intended/agreed Concensus regarding where and how long data from partners can be
stored

STRATEGIC AND SECURITY INTEROPERABILITY
![Page 11: INTEROPERABILITY CHALLENGES FOR CONTEXT AWARE … · Prince Singh . Marten van Sinderen . BDEI@IWEI Workshop . Nîmes, France . 27th May 2015 Context Logistics Context-awareness Interoperability](https://reader033.vdocument.in/reader033/viewer/2022042915/5f51558ce5f918157102bee6/html5/thumbnails/11.jpg)
Process interoperability is concerned with linking partners’ processes with through a choreography such that processes can proceed in synchrony Planning process – requires input in terms of available infrastructure,
cost, capacity etc. from the partners Bidding process – needs bids from partners who can fulfill a shipment
(or a part of it) Tracking Process - requires information from different databases and
information sources regarding location and process status Process tasks can be automated with IT applications - if applications are
directly connected (not hidden behind public process interfaces), there interoperability depends on API and software compatibility
27/5/15 BDEI 2015 11
PROCESS AND APPLICATION INTEROPERABILITY
![Page 12: INTEROPERABILITY CHALLENGES FOR CONTEXT AWARE … · Prince Singh . Marten van Sinderen . BDEI@IWEI Workshop . Nîmes, France . 27th May 2015 Context Logistics Context-awareness Interoperability](https://reader033.vdocument.in/reader033/viewer/2022042915/5f51558ce5f918157102bee6/html5/thumbnails/12.jpg)
Information (semantic) interoperability is the ability to share intended meaning between partners
Information exchange requires data transfer, i.e. technical (syntactic) interoperability Agreed formats and codings
Various standards exist governing information exchange in the logistics domain, but often companies have their own additions, versions and variations to these standards
Context-awareness may imply large amounts of data coming from various sources – apart from resolving heterogeneity, real time processing and quality of such data poses a challenge.

INFORMATION AND TECHNOLOGY INTEROPERABILITY
![Page 13: INTEROPERABILITY CHALLENGES FOR CONTEXT AWARE … · Prince Singh . Marten van Sinderen . BDEI@IWEI Workshop . Nîmes, France . 27th May 2015 Context Logistics Context-awareness Interoperability](https://reader033.vdocument.in/reader033/viewer/2022042915/5f51558ce5f918157102bee6/html5/thumbnails/13.jpg)
Starting from the value model, an enterprise architecture can be developed as reference for high-level interoperability Processes and collaboration functions assigned to actors Applications realizing these functions Servers hosting these applications and networks providing connectivity
Focus on interoperability with context information providers to enable context-aware synchromodality Assumptions: TCP/IP connectivity, REST over HTTP, simple
processes for subscription, query, and notification Challenge: information interoperability, esp. concerning disruprions

DISRUPTIONS
Disruptions are events in the domain (internal and external) which would delay delivery of the shipment Examples: slow traffic movement, rail accident, extreme weather
conditions.

For uniquely identifying this disruption Type of
disruption message
Information about the
source
Terminal, Hub, Road,
Pick up point, etc.
Used by planning module
E.g. visibility is 900m.
Information about the
event
Information about the message

Financial benefit of using context-aware synchromodal logistics is necessary for shipper to prefer it over current transportation techniques
Mutual trust between partners is important
Our data format does not contain underlying cause of the disruption. Can be difficult to determine Patterns for recurring disruptions can be identified and appropriate
actions taken to avoid it

DISCUSSION

Context-Aware Synchromodal Logistics Services contribute to efficient and green transport solutions There are many interoperability challenges for SLS at various levels
We investigated the concerns at information level for interoperability with context information providers
We proposed a provisional format and interpretation for disruption information from different sources
We will use this format for prototype development Improvements are to be made via discussion, questionnaires and
interviews with industry representatives and in our consortium (Synchromodal-IT project)
