Using Specification and Description Language to define and implement discrete simulation models

Abstract

The formal languages become important tools since they allow the complete understanding of the model and help in its implementation. However only a few simulation tools allow an automatic execution of a simulation model based in a formalization of the system. Specification and Description Language is a modern object oriented graphical formal language that allows the definition of distributed systems. It has focused on the modeling of reactive, state/event driven systems, and has been standardized by the International Telecommunications Union (ITU) in the Z.100. Since it is a graphical formalism simplifies the understanding of the model. In this paper we show how we can use Specification and Description Language to represent a discrete simulation model. We propose a solution, implemented in SDLPS, regarding how to manage the time in Specification and Description Language. Also, we show how SDLPS infrastructure allows a distribute simulation of the models.
