摘要
在对不确定性区间数多指标决策问题和区间数运算法则进行描述的基础上,通过区间数可能度的计算,将指标值从区间数映射到优劣关系等价的实数形式,最后依据简化的ELECTRE方法的计算步骤进行方案的排序.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.
On the base of the multiple attribute decision- making problems with uncertain intervals and algorithm on intervals, the possibility degree of intervals is calculated and intervals are transformed into equivalent real humors. Finally, alternatives are sequenced according to the simplified ELECTRE method＇s analysis steps. The analysis method is simple and practical. It overcomes the shortages that occur in ranking intervals in the traditional analysis methods.
