在群决策中,由于决策环境的不确定性,决策者给出区间数信息.基于区间数可能度矩阵公式和互补判断矩阵的排序公式,提出了一种组合不确定型OWA算子,它是不确定型OWA算子的推广.该算子能集结群决策中区间数信息,文中给出了其在应用的具体步骤,最后实例分析说明了该方法的有效性和可行性.
In the group decision making,decsion makers give the information of interval numbers because of the uncertainty of decision making environment.Based on the formula of possibility degree and the priority method of fuzzy complementary judgement matrix,a combined uncertain OWA operator is proposed,which generalizes the uncertain OWA operator.The combined uncertain OWA operator can be used to aggregate information of interval numbers in group decision making and its application procedures are presented in this paper.Finally,a numerical example is given to show the feasibility and effectiveness of the method.
