Parallel DEVS and Process-Oriented Modeling in Modelica

Abstract

This manuscript presents a new free Modelica library, named DESLib and composed of four packages: RandomLib, DEVSLib, SIMANLib and ARENALib. DESLib has been designed and implemented to facili- tate the description of discrete-event models using the Parallel DEVS formalism (using DEVSLib), and to fa- cilitate the process-oriented modeling of logistic systems (using SIMANLib and ARENALib). SIMAN- Lib and ARENALib models are designed as DEVS models, and implemented using DEVSLib, to facilitate its development, comprehension and maintenance. RandomLib includes functionalities to generate random numbers and random variates, and facilitate the development of stochastic models. The communication mechanism used to transport information between models in DESLib is presented. This mechanism facilitates the combination of DEVS and process-oriented models to describe discrete-event systems at multiple levels. DESLib also includes interfaces to combine its components with other Modelica libraries, facilitating the composition of multi-formalism and multi- domain hybrid models. DESLib can be downloaded from http://www.euclides.dia.uned.es.
