The workshop is concerned with, but not limited to, the following EOO related themes Acausality and its role in model reusability. Component systems for EOO languages. Discrete-event and hybrid modeling. Embedded systems and efficient-code generation. Modeling language constructs in support of simulation, optimization, diagnostics, and system identification. EOO mathematical modeling vs. UML software model-ing. Integrated hardware-software modeling of cyber-physical systems. Requirements for modeling traceability, translation, and integration. Formal semantics of EOO related languages. Multi-resolution / multi-scale modeling using EOO lan-guages. Model-driven development related to EOO languages. Numerical coupling of EOO simulators and other simula-tion tools. Parallel execution of EOO models. Programming / modeling environments. Real-time simulation using EOO languages. Reflection and meta-programming. Verification, type systems, and early static checking. Relation to functional reactive programming (FRP) and synchronous languages. Comparison with related causal or hybrid formalisms. Functional Mock-up Interface (FMI)
