Proceedings of the 8th International Workshop on Equation-Based Object-Oriented Modeling Languages and Tools

Abstract

We are very pleased to welcome you to EOOLT 2017, the 8th International Workshop on Equation-Based Object-Oriented Modeling Languages and Tools. Over the past 10 years, the EOOLT workshop series has been one of the main meeting points for researchers and practitioners interested in fundamental principles and concrete languages and tools for equation-based modeling. These kinds of languages have proven to have considerable advantages for physical modeling of complex cyber-physical systems, compared to traditional physical modeling approaches, where model components are block-oriented and only have inputs and outputs. Examples of commercially successful languages within this EOOL category are Modelica, gPROMS, VHDL-AMS, and Simulink/Simscape. In addition to these classic applications, there are two main developments that increase the importance for this class of languages. One trend is to integrate the equation-based models stronger into the overall process of model-based system engineering (MBSE). This requires the modeling of meta-information for requirements or optimization targets. Another trend is to include the clocked discrete control system into the model of the physical system. This is leading to the description of complete cyber-physical systems. These trends cause equation-based languages to change, to extend and to rise in their complexity. Yet the compilation of these languages is already now a highly complex field and generating simulation code for large systems remains a challenge.
