A Heterogeneous Simulation Framework Based on the DEVS BUS and the High Level Architecture

We describe a heterogeneous simulation framework which conventional simulation models and the DE (Discrete Event Systems Specification) models can interoperable. The framework conceptually consists three layers: the model layer, the DEVS layer, a the HLA (High Level Architecture) layer. The mod layer has a collection of heterogeneous simulation mod such as DEVS, CSIM, SLAM, and so on, to repres various aspects of a complex system. The DEVS la provides a common framework, called the DEVS BU so that such simulation models can communicate w each other. Finally, the HLA layer is employed a communication infrastructure, which supports sev good features for distributed simulation. The DEVS B has been implemented on the HLA and a simple exam of communicating two heterogeneous models has b developed to validate the DEVS BUS.
