A Metamodel-based Approach for Reusable Simulation Model Representation

The composition and reuse of simulation model are currently hot research topics in the area of complex system modeling and simulation.An unified simulation model representation is one of the key techniques to facilitate reuse.The model representation concept and its role in simulation are presented firstly.The reusable simulation models have specific demands on the specification and approach of model representation,which are summarized in the second part.According to these requirements,three major simulation model representation approaches and their shortcomings are analyzed next.The advantages of metamodel in software representation are widely acknowledged in recent years.With this in mind this paper presents a metamodel based approach for reusable simulation model representation,and the design strategy of metamodel-based representation specification is discussed in the final part.
