为描述和分析面向服务军事信息系统的功能结构、评价其性能,提出了一种层次化可执行的系统建模仿真方法。该方法结合IDEF3和EPC-D描述并分析系统功能、结构和数据流程,基于对象Petri网的仿真执行,评估系统性能,最终实现对面向服务军事信息系统的完整描述和准确评价。为提高系统建模仿真效率和模型描述的一致性,研究了不同层次间模型的转换关系。结合案例阐述了所提方法在实际中的应用,证明方法的可行性和有效性。
In order to describe and analyze the functional structure of service-oriented military information system and evaluate its performance, a hierarchical executable system modeling and simulation method is proposed. The method combines IDEF3 and EPC-D to describe and analyze system function, structure and data flow. Based on the simulation execution of object Petri net, the method evaluates the performance of the system and finally realizes the complete description and accurate evaluation of service-oriented military information system. In order to improve the efficiency of system modeling and simulation and the consistency of model description, the transformation relations between different levels of models are studied. Combined with the case, the application of the proposed method in practice is demonstrated, and the feasibility and effectiveness of the method are proved.
