摘要
针对属性权重信息完全未知或只有部分权重信息且属性值为三角模糊数的模糊多属性决策问题,提出3种基于模糊理想点的最优化决策模型.通过对这3种模型的求解,获得属性的权重,给出相应的对方案进行排序和择优的决策方法,从而为解决权重信息不完全的模糊多属性决策问题提供新的途径.
This paper establishes three optimization models based on fuzzy ideal points for multiattribute decision making problems in which the information on attribute weights is completely or partly unknow and the attribute values are given in the forms of triangular fuzzy numbers. By solving these three models, the attribute weights can be got. Some methods are proposed for selecting the most desirable alternatives. Finally, a numerical example is used to illustrate the proposed methods.
