The use of the UML within the modelling process of modelica-models

This paper presents the use of the Unified Modeling Language (UML) in the context of object-oriented modelling and simulation of hybrid systems with Modelica. The definition of a specialized version of UML for the graphical description and model based development of hybrid systems in Modelica - the UMLH - was taken place in the GENSIM project [1, 2]. For a better support of the modelling process, an UMLH editor with different views (class diagrams, statechart diagrams, collaboration diagrams) was implemented as a part of the Modelica simulation tool MOSILAB [3]. In the EOOLTworkshop the use of UMLH and its semantics will be demonstrated by the development of a simplified model of a Pool-Billiard game in Modelica.
