摘要
针对利用三角模糊数距离公式对模糊数排序中存在运算量大的问题,对已有的三角模糊数排序公式加以改进,有效地减小了计算量;并针对属性值为模糊数的多属性决策问题进行算例分析.
Aiming at a new ranking method for a triangle fuzzy numbers based on a new distance of triangular fuzzy number, the multi-attribute decision making is studied with fuzzy number valued index in an example , which is given to show the feasibility of the method.
