摘要
为了解决复杂模糊环境下的多属性决策问题,提出一种基于区间二元语言毕达哥拉斯模糊信息的MULTIMOORA和ELECTRE方法。首先结合毕达哥拉斯语言集和区间二元语言变量,提出了关于隶属度,非隶属度和语言变量均为区间值的区间二元语言毕达哥拉斯模糊集。其次对于传统MULTIMOORA方法中未考虑各模型权重的情况,构建单目标优化模型来确定模型权重。最后提出区间二元语言毕达哥拉斯模糊信息的MULTIMOORA和ELECTRE方法并且通过实例说明了该方法的可行性和有效性。
In order to solve the problem of multi-attribute decision making in complex fuzzy environment,MULTIMOORA and ELECTRE method based on interval 2-tuple linguistic Pythagorean fuzzy information is proposed.Firstly,by combining the Py-thagorean fuzzy linguistic set with interval 2-tuple linguistic variables,interval 2-tuple linguistic Pythagorean fuzzy set is pro-posed,in which the membership degree,non-membership degree and language variables are all interval values.Secondly,the weights between models are not considered in traditional MULTIMOORA method,so a single-objective optimization model is con-structed to determine weights of the model.Finally,MULTIMOORA and ELECTRE method based on interval 2-tuple linguistic Py-thagorean fuzzy information is proposed and effectiveness and rationality of the proposed method are verified by case analysis.
