基于多目标决策的BAS软件可靠性模型选择方法研究

Selection of BAS Software Reliability Model Based on Multi-objective Decision-making

针对BAS软件可靠性模型选择没有定量方法的问题,提出了一种基于多目标决策的BAS软件可靠性模型选择方法。首先对所有可行模型的每一属性进行定量表示,得到模型的优基数。然后确定属性加权系数,并对优基数进行求和。最终得到所有模型的优基数之和的大小即表示该模型的适用程度。以一组公开发表的失效数据为对象进行验证,成功找出该失效数据下的最适用模型,表明该方法是有效的、可行的。

Aiming at the problem that there is no quantitative method for BAS software reliability model,a method of BAS software reliability model selection based on multi-objective decision is proposed. Attributes of all feasible models is quantitatively expressed,and the optimal base number of the model is obtained. The weighting factor,the superior base number are determined.The size of the sum of the optimal base numbers of all models is the degree of applicability of the model. A set of publicly available failure data is validated,and the most suitable model under the failure data is found successfully,which indicates that the method is effective and feasible.
