基于相对熵的多属性决策排序方法
发布时间:2019-01-28 08:59
【摘要】:针对逼近理想解排序法(TOPSIS)的不足,从相对熵的概念出发,提出了求解多属性决策问题的新思路.利用被评价方案与理想方案和负理想方案的相对熵,定义了一种新的与理想方案的贴近度.据此给出一种新的排序方法— 相对熵排序法,并将此法与TOPSIS方法、夹角度量法和投影法进行对比.结果表明,在传统的TOPSIS方法、夹角度量法和投影算法排序都失效的情况下,相对熵排序法能够准确地给出方案的排序.
[Abstract]:In order to solve the problem of approximate ideal solution ranking method (TOPSIS), a new method for solving multi-attribute decision making problems is proposed based on the concept of relative entropy. By using the relative entropy of the evaluated scheme, the ideal scheme and the negative ideal scheme, a new degree of closeness between the evaluated scheme and the ideal scheme is defined. Based on this, a new sort method, the relative entropy sorting method, is presented and compared with the TOPSIS method, the angle measurement method and the projection method. The results show that under the condition that the traditional TOPSIS method, the angle metric method and the projection algorithm all fail, the relative entropy sorting method can give the ranking of the schemes accurately.
