CREATING DEVS COMPONENTS WITH THE METAMODELLING TOOL ATOM

DEVS is a well-known formalism that provides a rigorous basis for discrete event modelling and simulation. In this paper we present two possible DEVS metamodels that are used to automatically generate 1) a tool that allows the graphical definition of DEVS models and 2) Zope products that allow storing DEVS models in a model library under the Web Application Server Zope. The tool is capable of generating a representation suitable for simulation by an external DEVS solver. The generation of executable model representations and Zope products is realized by graph transformation. The tool, the simulator and the model library form a dedicated DEVS modelling and simulation environment. The paper demonstrates how dedicated, domain/problem-specific modelling and simulation environments can be easily generated from metamodels using graph transformation.
