Abstract:In this study; a system is presented and analyzed that automatically translates a model described within the Modelica framework into the Discrete Event System Specification (DEVS) formalism.

More specifically; this work interfaces the open-source implementation of Modelica; OpenModelica; and one particular software tool for DEVS modeling and simulation; the PowerDEVS environment; which implements the Quantized State Systems (QSS) integration methods introduced by Kofman.

The interface enables the automatic simulation of largescale models with both DASSL (using the OpenModelica run-time environment) and QSS (using PowerDEVS) and extracts features; such as accuracy and simulation time; that allow a quantitative comparison of these integration methods. In this way; meaningful insight can be obtained on their respective advantages and disadvantages when used for simulating real-world applications. Furthermore; the implemented interface allows any user without any knowledge of DEVS and/or QSS methods to simulate their systems in PowerDEVS by supplying a Modelica model as input only.
