AHP(Analytic Hierarchy Process)法在仿真可信度评估中经常使用,但传统的AHP法不能解决可信度评估结果的阶跃问题.为了解决这一问题,在明确了阶跃问题的主因是AHP相对权重的缺陷后,参考Petri网的相关定义,建立了AHP网的概念和数学基础;针对传统AHP相对权重的缺陷,进一步提出了增强型AHP网及相关定义、图例等;在网络定义的基础上,提出了AHP超越权重的概念及其数学表达式;确定了含有超越权重的AHP网节点取值算法和评估节点优先级算法;提供了一个应用AHP超越权重的仿真可信度评估实例,并获取了量化的评估结果.计算结果表明:含有超越权重的AHP体系能够解决可信度评估结果的阶跃问题.
AHP (Analytic Hierarchy Process) method is often used in the evaluation of simulation credibility, but the traditional AHP method can not solve the step problem of the credibility assessment results.In order to solve this problem, it is clear that the main cause of the step problem is AHP The definition and the mathematical basis of AHP network are established by referring to the related definitions of Petri nets. In view of the defects of the traditional relative weight of AHP, an enhanced AHP network and its related definition, illustration and so on are further proposed. Based on the definition of network On this basis, the concept of AHP over weight and its mathematical expression are proposed. The value algorithm of AHP network node with excess weight and the algorithm of evaluating node priority are determined. An evaluation example of the simulation credibility of AHP over weight is given. The quantitative evaluation results are obtained.The calculation results show that the AHP system with over-weight can solve the step problem of the credibility evaluation results.
