Abstract
The analysis and identification of the requirements needed to describe
P-DEVS models using the Modelica language are discussed in this
manuscript. A new free Modelica package, named DEVSLib, is presented.
It facilitates the description of discrete-event models according to
the Parallel DEVS formalism and provides components to interface with
continuous-time models, which can be composed using other Modelica
libraries. In addition, DEVSLib contains models implementing Quantized
State System (QSS) integration methods. The model definition
capabilities provided by DEVSLib are similar to the ones in the
simulation environments specifically designed for supporting the DEVS
formalism. The main additional advantage of DEVSLib is that it can be
used together with other Modelica libraries in order to compose
multi-domain and multi-formalism hybrid models. DEVSLib is included in
the DESLib Modelica library, which is freely available for download at
http://www.euclides.dia.uned.es.
