Discrete Event Systems Specification (DEVS)חינם לחברי האיגוד

Model Based System Engineering (MBSE) refers to the trend to use models systematically throughout the design process. MBSE has been struggling to find a way to connect the blueprint models that describe the initial architecture with ways to check and evaluate these plans. Simulation has become the preferred means to support this goal. Discrete Event Systems Specification (DEVS) is a model-based way to perform simulation and connect the stages of MBSE.

DEVS enables you to represent real systems (existing or hypothetical) so they can be digitally represented and simulated. It is a part of a framework and theory of modelling and simulation and is unique as a way of constructing a simulation model that is based on a mathematical theory of systems. In this talk, we answer some questions such as:  How/when was DEVS born? How does it compare to other abstractions? Where does it make most sense to use?  Where will  it lead? What are the potential benefits of DEVS?  What is made possible as a direct result of using DEVS?

After a short review and some example case studies, we present our vision for fully integrated modeling and simulation support of MBSE life cycle based on DEVS.  We close by considering the current state-of-the-art in tools available and under development towards this vision.
