What is an Interface?
• Trivial definition:
– A boundary across which two systems meet and act on or communicate with each other.
• Extended definition: • Anything, across, through, over, or around which two
things meet and act on or communicate with each other.

Extended Interface Modeling
• Multiple levels/phases/aspects of interaction.
• Multiple forms of interface realization.
• Dual physical-logical realization.
• Encapsulation and suppression vs. decomposition and unfolding.
• Measurable characteristics and objectives (capacity, size, stability, availability, cost, throughput, criticality, etc.)

Interfaces in the broadest sense
• The internet
• Language
• Friendship / Human relations
• The atmosphere/ magnetosphere
• Gravity
• Common Sense
• You name it!

Summary
• The conceptual similarity of interface modeling and risk modeling.
• A structured approach to risk identification through interface modeling.
• Risk modeling on top of the system model, not separately.

The Enterprise Systems Modeling
Laboratory
• A unique education and research studio concept.
• Implementation of powerful tools and methodologies.
• Participating in several projects across the world (NASA SMACKDOWN, TALOS, VISIONAIR, ISO, SEBoK)

• NASA Smackdown Project The SISO Simulation Smackdown is an effort to promote better awareness and understanding of both the importance and the complexity of modern modeling and simulation through hands-on mentoring and participation with modeling and simulation practitioners.
• TALOS autonomous robot project
Develop and field test the innovative concept of a mobile, modular, scalable, autonomous and adaptive system for protecting European borders.
Our contribution to both projects is VIVID OPM – A framework for model-driven simulated animation

• ISO Standardization of OPM
• We advocate a model-based systems engineering approach for creating “industry-strength” technical documents
• Technical document authoring is the function of the system – the organization – that delivers the technical document.
• Systems Engineering Body of Knowledge (SEBoK) • The SEBoK is a guide to the body of knowledge, providing references to detailed sources
for additional information.
• The SEBoK is primarily domain independent, with implementation examples providing the domain-specific context.
• The SEBoK is focused on engineered systems: products, services, systems of systems (SoS), and enterprises
