摘要
脆性作为系统的基本属性,对系统稳定性的影响不言而喻。为了研究地空导弹(ground to air missile system,GAMS)装备指挥系统(equipment command system,ECS)中的脆性传播特性,提出了基于性能指标的个体脆性评价方法,以及基于业务流程的个体间脆性传递模式;通过任务流程分解的方法研究了不同任务阶段中不同个体间的脆性传递关系和传播机制;并在计算装备指挥系统实例的基础上,分析了脆性在系统中传播的基本过程以及初始扰动对ECS整体脆性的影响。其中,对个体脆性变化及脆性传播过程的研究符合地空导弹装备指挥系统的脆性变化规律,也满足脆性理论对系统脆性特征的描述。
Brittleness is a basic property which is important to system stability. In order to find out the brittleness spreading performance in equipment command system （ECS） of ground to air missile sys- tem （GAMS） , the brittleness evaluation method of ECS units based on the performance Index is pro- posed,and the brittleness delivering mode through ECS workflow is put forward. Afterwards, with task workflow decomposition, the following part studies the brittleness delivering process and spreading mecha- nism of ECS units in different mission steps. And in the last part the brittleness spreading process in ECS is studied and the influence of initial condition to ECS brittleness on given results of ECS example calcu- lation is obtained, which proves that the ECS brittleness definition and brittle basic features are in line with the description of unit brittleness and brittleness spreading process in ECS task.
