摘　　要：基于模糊数上一种距离定义,针对属性值和属性权重均为三角模糊数的多属性决策问题,给出一种基于理想点法的多属性决策方法。该决策方法具有运算简洁的特点。最后,以实例说明该方法的有效性。Based on a distance definition between two fuzzy numbers, a method based on TOPSIS is presented to deal with the multi - criteria decision - making problem, in which the number and the weight of criteria are triangular fuzzy numbers. The operation of the proposed method is simple. Finally, a practical example is provided to illustrate the developed approach.
