New Weight Approach for Interval Number Complementary Judgement Matrix

摘要

New consistency definitions and weight approach deriving from the interval number complementary judgement matrix are studied.First, pointing out the defective of the presented interval number complementary judgement matrix definition, and proposing a new consistency definition. Based on the logarithm derivation theory, it gets a new ranking method of interval number complementary judgement matrix. Finally, the paper gives the ranking method steps to illustrate the use.
