Abstract

The established Discrete Event System Specification (DEVS) offers opportunities to comprehensively describe discrete event systems. In this paper the classic DEVS approach is extended with specifications and methods for continuous and variable structure modelling to hybrid models with a variable modular, hierarchical structure. To let engineers benefit from these powerful modelling instruments, they are integrated into the well-accepted and popular scientific and technical computing environment (SCE) Matlab. Furthermore, integration with other computing methods provided by the chosen SCE is obvious and can be accomplished. We appreciate DEVS based algorithms for modelling and simulation in SCEs as a complement and addition to existing tools as Simulink, Stateflow and SimEvents for engineering tasks such as e. g. discrete eventbased control design. Moreover, a SCE provides a prototyping environment for the evolution of the DEVS approach itself.
