加权几何Copula集成算子及其在多属性决策中的应用

Weighted Geometric Copula Aggregation Operator and Its Application to Multiple Attributes Decision Making

针对多属性决策中的信息融合环节,提出了一种加权几何Copula集成(WGCA)算子,定义了基于Copula函数的实数运算法则,并对WGCA算子的相关性质进行了证明。在此基础上,提出了一种基于WGCA算子的多属性决策方法,并通过实例说明了该方法的有效性和合理性。

Aiming at the information fusion of the multiple attributes decision making, a weighted geometric copula aggregation（WGCA） operator is put forward, some new operational rule of real number based on Copula are defined and some properties of WGCA operator are proved. An approach of multiple attributes decision making is proposed and the validity and rationality of the proposed approach is verified through its application in a given case.
