integrating parallel devs and equation-based object-oriented modeling
The benefits of integrating the Parallel DEVS (P-DEVS) formalism with the Equation-Based Object-Oriented modeling languages (EOOL), which constitute the state-of-the-art for continuous-time system modeling, are discussed. The characteristics of the Equation-Based Object-Oriented (EOO) methodology are presented. The requirements to describe P-DEVS models using an EOOL are evaluated. These requirements are detailed for the case of the P-DEVS formalism and the Modelica language, with the introduction of the DEVS-Lib Modelica library. DEVSLib facilitates the description of P-DEVS models in Modelica, and allows the combination of DEVS models together with other Modelica libraries in order to construct multi-formalism hybrid models. DEVSLib has been developed by the authors and is freely available at http://www.euclides.dia.uned.es.
