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分析、排序、择优和评价,以找到一种简捷方便的排序方法.运用优势粗糙集理论对决策对象进行详细的分析,在此基础上,针对多属性决策排序结果中“并列”决策现象的存在,将基于信息量的属性重要性度量引入到优势度排序方法中,进一步细化排序结果.最后通过与其他排序方法在具体算例中的对比分析,验证了该方法的合理性、有效性.

Abstract: The essence of the multi­attribute decision making problems is to analyze,sort,select and evaluate the alternative objects by existing decision­making information,aiming to find a simple and convenient method of sorting.However,the dominance relation is an important method of solving the multi­attribute decision making problems.Firstly,Dominance Rough Set Theory is used for detailed analysis on decision­making objects.On this basis,according to the research of the sorting methods in the complete ordered information system,we propose a dominance degree sorting method based on attribute weight to solve the problem that parallel decision phenomenon maybe result in the sorting failure in multi­attribute decision making sorting results.This new sorting method takes into account the importance of attributes in the sorting results,and introduces the attribute measurement based on information quantity into the dominance degree sorting method,to further refine the result of the sort.Furthermore,a specific real example was used to show the validity and advantages of this method.Finally,compared with other sorting methods in specific cases,the results illustrate that the new sorting method can not only solve the schedule problem in real life,but also make the sorting results more reasonable and effective.
