TOPSIS Method for Multiple Attribute Decision Making with Intervals

针对具有不确定性区间数的多指标决策问题 ,给出了一种逼近于理想点 (TOPSIS)的分析方法·首先对区间数多指标决策问题和区间数运算法则进行了描述 ;然后依据传统的TOPSIS方法的基本思路 ,给出了解决区间数多指标决策问题的计算步骤·该分析方法具有简单、实用的特点 ,它克服了以往研究此类决策问题时所遇到的区间数难以排序的问题·最后给出了一个算例·

With respect to multiple attribute decision making problems with uncertain intervals, an analysis method for similarity to ideal solution was proposed. In the method,the multiple attribute decision making problems with intervals and algorithm on intervals were introduced. Based on the traditional TOPSIS method a calculation steps for solving the decision making problems with intervals was given. The analysis method is simple and practical. It overcomes the shortages that occur in ranking intervals in the traditional analysis methods. A numerical example was given to illustrate the use of the proposed method.
