针对现有的模糊数比较与排序方法没有考虑或者不满足决策者风险偏好的不足,构造一种基于质心兼顾模糊熵以及风险态度的模糊数综合排序新指标.在考虑决策者的风险态度来定义表征决策者风险态度的相对分离度指标的基础上,基于相对分离度和质心,融合模糊数的熵信息,构造新的模糊数综合排序指标,同时对现有散度指标用于模糊数排序方法进行深入分析并指出其不足.分析结果证明了排序新指标的合理性,与已有的排序方法比较,文中排序方法更具优越性.
針對現有的模糊數比較與排序方法沒有攷慮或者不滿足決策者風險偏好的不足,構造一種基于質心兼顧模糊熵以及風險態度的模糊數綜閤排序新指標.在攷慮決策者的風險態度來定義錶徵決策者風險態度的相對分離度指標的基礎上,基于相對分離度和質心,融閤模糊數的熵信息,構造新的模糊數綜閤排序指標,同時對現有散度指標用于模糊數排序方法進行深入分析併指齣其不足.分析結果證明瞭排序新指標的閤理性,與已有的排序方法比較,文中排序方法更具優越性.

In view of the existing fuzzy number comparison and ranking methods not consider or not meet the decision maker's risk preference, the author construct a consideration of fuzzy entropy and risk attitude ranking new indicators based on centroid. In considering the decision maker's attitude to risk basis is defined to express the risk attitude of decision-maker relative separation index, relative isolation and centroid based on information entropy, fusion of fuzzy numbers, constructed the ranking index is new, the dispersion index for fuzzy number ranking method of in-depth analysis and pointed out the inadequacies. Analysis results show that the rationality of new index ranking, the comparison and sorting method has more superiority.
