定义了二型三角模糊数的相关概念、运算规则和可能度公式,并针对隶属度难以用精确数进行衡量的多准则决策问题,提出了基于二型三角诱导OWA算子的多准则决策方法.该方法通过二型三角诱导OWA算子确定方案的综合准则值,并由二型三角模糊数的可能度公式计算出综合准则值的排序,进而得到方案的排序.最后通过实例分析验证了所提出方法的有效性和可行性.
The related concepts, operation rules and probability formulas of type II triangular fuzzy numbers are defined. A multi - criteria decision - making method based on type II triangulation - induced OWA operators is proposed for multi - criteria decision problems whose membership degree is difficult to be measured by exact numbers. In this method, the OWA operator is used to determine the comprehensive guideline value of the scheme, and the rank of the comprehensive guideline value is calculated from the formula of the degree of triangular trigonometric fuzzy number. Finally, the ranking of the scheme is obtained.At last, The effectiveness and feasibility of the method.
