不确定多属性决策中区间数排序的一种新方法

An New Method of Interval Numbers Ordering in Uncertain Multiple Attribute Decision-making

根据格序决策理论,提出不确定多属性决策中区间数排序的新方法,将综合评价值区间数分为可比较与不可比较区间数,对可比较区间数利用区间数上界进行比较来排序,而对不可比较区间数利用均值及区间上界比较来排序,方法比格序决策法和期望-方差法等方法更加简单易行,进一步提高了决策效率.最后通过算例验证方法的可行性和有效性.

There are many methods in resolving the multiple attribute decision-making problem, but their calculating quantity is big, so that it has affected decision-making efficiency. For the sake of making up the above-mentioned defects, The interval numbers of synthesis evaluation value are divided into comparison interval numbers and uncomparison interval numbers, the comparison interval numbers are ordered by making use of interval upper bound, and the uncomparison interval numbers are ordered by making use of mean value comparison and interval block upper bound, this method is easy to do more supplely than that of lattice order decision-making and that of mean-variance, which decision-making efficiency can be verified higher, at last the fact is tested by two method comparison calculating examples.
