Interoperation of DEVS models and differential equation models using HLA/RTI: hybrid simulation of engineering and engagement level models

A hybrid model is a combination of models developed in various simulation development environments. A war game model is a kind of hybrid model and consists of multiple level models. Engineering level models are interested in the change of values via time and process mathematical equations, and most of them are developed in MALTAB/Simulink. Engage-ment level models are concerned about state transitions by events and modeled using the Discrete Event Systems Speci-fication (DEVS) formalism. This paper proposes a framework for interoperation of simulation tools for engineering and en-gagement level models simulation. The framework employs the High Level Architecture (HLA) to reuse existing models and suggests specific interfaces for MATLAB/Simulink. The proposed framework is demonstrated through simulation of a simple war game model including heterogenous models. 1.
