Confidence Degree Method for Ranking Interval Grey Number with Whitening: Function

摘要

The confidence degree formula for the comparison between two interval grey numbers with whitening function is put forward, and a detailed study on relationships between the formula and the ones proposed by other scholars is completed. Then, based on the formula, a confidence degree method for ranking interval grey numbers is given, and some of their properties such as complementary, transitivity, compatibility, etc. are studied. Finally, its application is given to demonstrate the efficiency of the algorithm.
