摘　　要：系统能力评估通常是一个多属性决策问题,传统的评估方法有基于集结算子的评估方法和基于标准对象的评估方法.针对这两类方法的不足,提出一种将粗糙集理论和集对分析理论相结合的区间粗糙集对法.首先给出了指标权重的确定方法,它是一种基于区间数有序相离度和属性重要度思想的主客观相结合的确定方法;其次给出了区间数转换成联系数的方法,同时详细地给出了区间粗糙集对法的算法步骤;最后,用一个实例说明了该方法如何应用,并将结果与区间TOPSIS法进行了比较,证明了算法的有效性.System capability evaluation is a multiple attribution decision-making problem.The typical evaluation method can be classified into two types,one based on amalgamation operator and the other based on standard object.To make up for the limitations existed in these methods,a new method called interval rough set pair method is presented in this paper.The method of how to deicide index weight is given firstly,which is a unification of object and subject based on order spread of interval number and attribute importance.Then the transfer of the interval number to a connection number is introduced following by the steps of the new method.And an example is given to show the use of the new method.The comparison between our method and the typical interval TOPSIS verifies the validity of the new method.
