Workflow Simulation of Equipment Command Based on HLA

With Object Oriented (OO) method, this paper analyzed the operational process of Equipent Command (EC) and its information exchange capability with external environment. Consequently the EC federate was developed according to High Level Architecture (HLA) standards. This paper developed graphical modeling tool for workflow based on VC++, and created workflow model for EC in this tool based on timed colored Petri net. By setting simulating environment, this tool could automatically create simulation models that could be executed in executable specification tool - ExSpect. Simulation models were integrated into Run-Time Infrastructure (RTI) by ExSpect´s Component Object Model (COM) interfaces. By deploying resources dynamically during simulating process, this paper displayed the transformation of system state in animated cartoon interface, and analyzed the bottleneck and operational efficiency of EC business flow. Furthermore, it proposed improvement measures for workflow model. Consequently, it carried out Business Process Reengineering (BPR) for EC.
