A DSM-BASED MULTI-PARADIGM SIMULATION MODELING APPROACH FOR COMPLEX SYSTEMS

Complex systems contain hierarchical heterogeneous subsystems and diverse domain behavior patterns, which bring a grand challenge for simulation modeling. To cope with this challenge, the M&S communi-ty extends their existing modeling paradigms to promote reusability, interoperability and composability of simulation models and systems; however, these efforts are relatively isolated and limited to their own technical space. In this paper, we propose a domain specific modeling (DSM)-based multi-paradigm modeling approach which utilizes model driven engineering techniques to integrate current M&S para-digms and promote formal and automated model development. This approach constructs a simulation model framework to architect the structure of the overall simulation system and combines multiple M&S formalisms to describe the diverse domain behaviors; moreover, it provides domain specific language and environment support for conceptual modeling based on the model framework and formalisms. An appli-cation example on combat system effectiveness simulation illustrates the applicability of the approach.
