一种基于置信度的软件构件可信性度量模型

软件构件在测试过程中存在空间局限性以及测试环境的单一性，需要根据系统运行的状态来对构件的可信性进行评估。通过引入置信度的模型对构件的可信度进行评价，给出一个构件可信的度量模型。在度量模型中采用三角模糊数层次分析法确定运行状态对置信度的影响权重。仿真结果表明，该模型能够有效地度量构件的可信度。

A MEASURE MODEL OF SOFTWARE COMPONENT RELIABILITY BASED ON CREDIBILITY

During testing procedure of software construction, there are the space locality and the monotony of test environment, which is needed to evaluate component credibility according to the status of system operating. We propose the measure model of the component credibility to evaluate the component credibility. Adopting the method of triangle fuzzy analytic hierarchy, we can determine the running status for the affect weight of credibility.The simulation results show that this model can measure component credibility effectively.
