摘要
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 concepts,operating rules and possibility degree of triangular type-2 fuzzy numbers are proposed.For the problem of the multi-criteria decision making that the uncertainty of the criteria values is difficult to give with an accurate number,triangular type-2 fuzzy number is used to show the decision information.And multi-criteria decision-making method based on triangular type-2 induced OWA operator is proposed.In this method,the comprehensive criteria are attained by using the triangular type-2 induced OWA operator.Then the ranking of alternatives is obtained by using the possibility degree.Finally,an example analysis shows the feasibility and effectiveness of the proposed method.
