装备体系结构脆性及其评价方法

Brittleness of Equipment System-of-System Architecture and Evaluation Method

为了表征多元环境下装备体系在遭受自身或外部干扰和破坏后的抵抗能力,根据装备体系结构网络化的特点,在对其组成系统进行集对分析的基础上,对装备体系结构的脆性进行评价分析。该方法首先讨论了装备体系结构脆性及其传递机理,然后通过引入信息熵的概念来定量地评估了装备体系结构的脆性,用以衡量在危机因素发生时装备体系结构发生崩溃的不确定程度。最后,以舰载机保障体系为例,证明该脆性评价方法对于装备体系的设计具有一定的意义。

In order to reflect the ability to resist disruptions of the equipment System-of-Systems(SoS),which is always under multiple conditions,after the influence of both intra and extra disruptive events,according to the characteristics of networked equipment SoS architecture,an effective brittleness evaluation method was proposed on the basis of set pair analysis.In the method,brittleness of equipment SoS architecture and its trigger mechanism were discussed firstly,then,brittle entropy was introduced to evaluate the brittleness of equipment SoS architecture,so as to measure the degree of uncertainty whether the system fail when risk factors occurred.Finally,taking brittleness evaluation of aircraft support SoS architecture as an example,application of the method is meaningful for design of equipment SoS.
