基于证据理论的群组DEMATEL改进方法
Improved group DEMATEL approach based on evidence theory
摘要
Abstract
In group DEMATEL procedures, how to incorporate expert opinion reasonably is an important technology core for ensuring the effectiveness of group decision making. However, there are some drawbacks in existing literature. Not only the inte-grated mechanism of expert opinion is unclear, but also the way of single expert judgment has some subjectivity and arbitrary. To overcome the above disadvantages, an improved group DEMATEL approach based on evidence theory is presented by over-viewing the traditional group DEMATEL method and systematically analyzing its drawbacks. There are two advantages in the improved approach. On the one hand it reflects the uncertainly of expert opinion with confidence belief function, and effectively integrates group expert opinion with Dempster’s combination rule, on the other hand it realizes expert evidence information interaction according to the thought of overall judgment. The improved approach is validated to be reasonable and would be well applied to solve the real world problems.关键词
