摘　　要：多属性决策问题的实质是利用已有的决策信息,通过一定方式对备选对象进行排序并择优.针对区间序信息系统中单一优势关系过于宽松或严格往往会引起排序失效的问题,本文利用三种区间数优势关系对决策对象进行详细分析,并利用向量相似度和并列对象两种准则对三种优势关系下获得的排序向量进行赋权,最终根据加权排序向量得到排序结果.最后在具体算例中与其他方法进行比较分析,该方法不仅能有效解决单一优势关系排序失效的问题,且获得的排序结果更加合理.The essence of the multi-attribute decision making problems is to evaluate and sort the alternative objects by using the existing decision-making information in some way.In order to solve the problem that the single dominance relation defined on interval-valued ordered information system may lead to the failure of the sorting method due to too loose or strict,under three kinds of dominance relations,this paper analysis firstly the decision-making objects in detail,and then add weight value to each sorting vector by using the vector similarity and parallel object two kinds of criteria,at the end,obtain the sorting results based on the weighted sorting vector.Example results show that,comparing with other sorting methods,the new sorting method can not only solve the problem of ranking failure by single dominance relation,but also make the sorting results more reasonable.
