An executable modeling and analyzing approach to C4ISR architecture

To analyze the behavioral model of the command,control,communication,computer,intelligence,surveillance,reconnaissance(C4ISR)architecture,we propose an executable modeling and analyzing approach to it.First,the meta concept model of the C4ISR architecture is introduced.According to the meta concept model,we construct the executable meta models of the C4ISR architecture by extending the meta models of fUML.Then,we define the concrete syntax and executable activity algebra(EAA)semantics for executable models.The semantics functions are introduced to translating the syntax description of executable models into the item of EAA.To support the execution of models,we propose the executable rules which are the structural operational semantics of EAA.Finally,an area air defense of the C4ISR system is used to illustrate the feasibility of the approach.

基于HLA的指挥控制网络模型研究

建立指挥控制网络模型是指挥自动化系统仿真的一个重要环节,在基于HLA的指挥控制网络仿真中,结合其仿真体系结构,建立了针对指挥控制网络仿真的模型,描述了指挥控制网络的各种要素以及要素间的关系,给出了计算链路可达性的一种算法。对指挥控制网络仿真成员进行了设计,通过模型在基于HLA指挥控制仿真系统中的应用,满足了指挥控制网络仿真的实时性需求,同时具备较强的适应性和可扩展性。
