一种解决多属性决策问题的新方法

摘要

For the MADM problems in which the attribute values are the interval rough numbers,a multi-attribute decision-making method based on the similarity coefficient and connection numbers is put forward to compensate for the lack of qualitative analysis method. The reliability in the indicators of maintenance strategy selection is intro-duced and the economy,timeliness and other indicators are taken into account with combinaton of the instance of forklift hydraulic pump maintenance-mode selection. The whole operation process and results demonstrate the effec-tiveness of this method. The multi-attribute decision-making problems are deeply explored in the theory and prac-tice by using fuzzy mathematics.%针对属性值为区间粗糙数且权重未知的多属性决策问题，提出了基于相似系数和联系数的多属性决策方法，该方法可以弥补定性分析方法的不足。结合叉车液压泵维修方式选择的实例，在维修策略选择所依据的属性上引入了有关可靠性的维修指标，并同时考虑了经济性、时效性等指标。解决实例的整个运算过程及结果很好地验证了该方法的有效性。对利用模糊数学处理多属性决策问题进行了理论与实践的探索。
