决策信息数据为区间数的一种多属性群决策方法

为了解决属性值为区间数的多属性群决策问题,提出了一种以决策信息数据为区间数的多属性群决策方法.首先分析了评价专家权重的计算方法; 然后采用区间数熵值法确定属性权重; 最后在确定评价专家权重与属性权重后对每个方案的综合有效评价值和属性的正负有效综合理想属性值进行测度,以此求出每个方案的有效综合属性测度结果,并进行排序.采用实例验证表明,该方法操作简单,便于计算,能够快速取得正确的排序结果.

A multi - attribute group decision - making method for interval number decision information data

In order to solve the problem of multi - attribute group decision - making with interval number of attribute values, multi - attribute group decision - making with one type interval number decision information data is proposed. Firstly, the calculation method to the evaluation experts' weight is presented. Then, using interval number entropy method, the attribute weight is obtained. Finally, when ascertain the weights of experts and attributes is finished, the comprehensive, effective evaluation value and the comprehensive, ideal, positive, negative, effective attribute value to each scheme are measured, thus the effective, comprehensive attribute measurement results of each scheme is obtained and sorted. A case is employ to verify the method is simple to operate, easy to calculate, quickly and perfect to sort.
