Parallel DEVS and Process-Oriented Modeling in Modelica

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 facilitate the description of discrete-event models using the Parallel DEVS formalism (using DEVSLib), and to facilitate the process-oriented modeling of logistic systems (using SIMANLib and ARENALib). SIMANLib 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 multidomain hybrid models. DESLib can be downloaded from http://www.euclides.dia.uned.es.
