允许偏差优序法

在多目标决策中,当目标函数的重要性不同时,在求最佳妥协解的过程中人们常常引入权重。目前确定权重的方法虽然很多,由于各种计算方法的局限性和各目标函数之间的不可公度性,因此决策者想通过求得的权重来准确地反映各目标函数的重要程度是困难的。本文提出对于重要性不同的目标函数不通过计算权重而直接使用允许偏差的方法来反映各目标函数的重要性,从而求得多目标决策问题中的最佳妥协解。

An Optimal Compromise Method in the Multiobjective Decision Problem

When the important characters of objective functions are different from each other an optimal compromise solution is often decided by the method of weight in the multiobjective decision problem. But that the weight is decided correctly is difficult. In this paper, a method that is nothing about weight is proposed to find an optimal compromise solution is an efficient solution.
