Conference article

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.
