基于相对接近度的多指标决策与评价方法及应用

在分析现有多指标决策与评价方法的基础上,指出了目前使用的“简单线性加权法”进行多指标决策与评价方法的局限性及不足,然后通过定义理想点与负理想点,以及引入距离测度等概念,构造了相对接近表示式,并以此作为多指标决策与评价规则,文中重点比较分析了该方法相对于其他算法的优点,并通过算例将本文采用的方法与其他方法计算结果进行比较,分析了造成结果差异的原因,从而说明了该的科学与合理 性。

A Method for Multi-indictes for Decision and Evaluation Based on Relative Approximation

Based on the analysis of other multi-indictes for decision and evaluation methods, this paper points out the limitation of "simple add weight (SAW)" method. Then by defining the ideal point and negative point and introducing distant measure, an expression of relative approximation is constructed it is the rule of multi-indictes for decision and evaluation. By the differences between the upper method and the other methods, the paper gives an example and analyses the causations between the different meth- ods, then points out the rationality of the method.
