DoDAF标准的系统效能评价

System Effectiveness Evaluation Based on DoDAF Standard

基于美国防部系统框架标准的系统动态性能测量和评价,以着色Petri网为仿真工具,用系统效能分析方法实现。以美军远程攻击部队ESG保卫太平洋上A岛为例,先分解出其防御系统进行CPN建模。包括预警机构、指挥中心、引导机构和执行机构等单元。选择系统在单位时间内摧毁威胁的数量和处理时间以及逃逸率作为评价系统效能的指标进行仿真分析,同时为系统设置不同的初始值,得到不同状况下系统的性能轨迹,由此完成评价。

System effectiveness evaluation based on DoDAF standard is simulated by Colored Petri Net and implemented with the method of system effectiveness evaluation. This paper takes example for the ESG （Expeditionary Strike Group） protecting the A island on the Pacific Ocean, then analyzes the defense system and induces to the CPN modeling, This system includes alert organization, command center, lead and execution departments, The number of the destroyed threat, the executed time and escaped rates in the unit time are chosen as the guide lines to simulate and analyze the system. Also set many different initial values in order to obtain the performance trace in different status, so can accomplish this evaluation.
