Introduction:During the past decade; integrated model-based design of complex cyber-physical systems (which mix physical dynamics with software and networks) has gained significant attention. Hybrid modeling languages based on equations; supporting both continuous-time and eventbased aspects (e.g. Modelica; SysML; VHDL-AMS; and Simulink/ Simscape) enable high-level reuse and integrated modeling capabilities of both the physically surrounding system and software for embedded systems. Using such equation-based object-oriented (EOO) modeling languages; it has become feasible to model complex systems covering multiple application domains at a high level of abstraction through reusable model components.

The interest in EOO languages and tools is rapidly growing in the industry because of their increasing importance in modeling; simulation; and specification of complex systems. There exist several different EOO language communities today that grew out of different application domains (multi-body system dynamics; electronic circuit simulation; chemical process engineering). The members of these disparate communities rarely talk to each other in spite of the similarities of their modeling and simulation needs.

The EOOLT workshop series aims at bringing these different communities together to discuss their common needs and goals as well as the algorithms and tools that best support them.

There was a good response to the Call for Papers. Ten papers were in the end accepted for full presentations whereas two work-in-progress papers were accepted for shorter presentations. One additional presentation was invited by the workshop organizers. All papers were subject to rather detailed reviewing by the program committee; on the average; four reviews were received per manuscript submitted.

On behalf of the program committee; the Program Chairs would like to thank all those who submitted papers to EOOLT’2011. Special thanks go to the program committee members for reviewing the papers on a strict time schedule.
