C^4ISR系统开发的仿真支持过程分析与建模

Analysis and Modeling on Simulation Support Process of C^4ISR Development

C4ISR(Command、Control、Communication、Computer、Intelligence、Surveillance and Reconnaissance)系统开发的仿真活动贯穿于系统全生命周期的各个阶段,仿真支持过程联系着C4ISR系统开发仿真的各类要素。首先对C4ISR系统开发仿真支持的内容进行分析,从生命周期维、仿真产品维和仿真任务维三个维度描述仿真支持内容之间的联系。然后分析了C4ISR系统开发仿真支持过程的层次性,应用UML描述了支持过程中的仿真项目模型和仿真过程模型。在此基础上,应用基于Petri网的工作流网,对C4ISR系统开发的仿真支持过程进行建模,分析了支持过程中活动、产品、角色、约束四类要素的Petri网表示方式。最后在一个C4ISR系统开发仿真支持实例中应用以上分析和建模方法,验证了方法的可行性和应用效果。

The all life circle of C^4ISR（Command、Control、Communication、Computer、Intelligence、Surveillance and Reconnaissance）system development is full of various simulation activities.The simulation support process organizes different simulation elements together.First,this paper analyses the content of the simulation support.Through a three-dimension-view model,the paper describes the constitute relationship of whole simulation support elements.Second,the paper demonstrates hiberarchy in the simulation support process,and describes simulation project model and simulation process model in UML.Third,applying with work flow net based on Petri net,the paper models the simulation support process,whose four elements,activity,product,actor and rule,are given Petri-net express.At last,one simulation support case for C^4ISR development is solved with analysis and modeling method proposed,which validates feasibility and effect of the method.
