Enhancing SDLPS with co-simulation

The increasing complexity of the systems that can be analyzed using simulation techniques requires that the tools, not only become more powerful, but can better express the relationships between the various components comprising the model. This presents two problems. The first related to how to express the relationships between the different elements of the model. An a second related to how can we use and reuse existing simulation models that answer many times, comprehensively but partially, specific aspects of certain systems In this paper we present a methodology based on Specification and Description Language, a formal and graphical language, that allows using in a single simulation model different simulators (co-simulation). This simplifies the interaction and the participation in a project of multidisciplinary teams. In addition, we cite a tool that implements this methodology.
