基于FAHP的构件安全性量化评估方法

摘要

It is needed to assess the safety of the chosen components when applying component technology to develop the Safety-critical System(SCS). On the basis of the Analytic Hierarchy Process(AHP), the Fuzzy AHP(FAHP) approach is used to analysis the node weight of components. The fuzzy information is identified with triangular fuzzy number and the node data is processed with fuzzy membership function. The approach is used to analyze the safety of components and experimental result shows that it is significant to the safety assessment of components.%应用构件开发安全苛求系统时,需要对所选用的构件进行安全性评估.为此,以层次分析法为基础,设计模糊层次分析法(FAHP)以确定构件的节点权重,利用三角模糊数标识模糊信息,通过模糊隶属函数对节点信息进行相应处理.实例应用结果表明,该方法对构件的安全性评估效果较好.
