Research of Ranking Method Based on Improved Possible Degree Dominance Relation
Zhang Qi-we · 2015
The dominance relation is an important method of solving the multi-attribute decision problem and researching the incomplete interval-valued information systems.According to the research of the ranking methods in the incomplete interval valued information system,we proposed a ranking method of improved possible degree dominance relation to solve the problem that too many attributes maybe result in the ranking failure.This new ranking method combines the interval-valued dominance relation with the possible degree,improves the weakness of the definition of classic dominance relation and defines the average comprehensive dominance degree.Finally,compared with other ranking methods such as∝-βdominance relation and tolerance dominance relation in specific cases,this ranking method of improved possible degree dominance relation can not only solve the problem in the incomplete interval-valued information systems,but also make the ranking results more reasonable and effective.
