Some issues on Distance and Similarity measures of dual hesitant fuzzy sets

摘要

The Dual Hesitant Fuzzy Sets (DHFSs) is a useful tool to deal with vagueness and ambiguity in the multiple attribute decision making (MADM) problems. The distance and similarity measures analysis are important research topics. In this paper, we propose some new distance measures for dual hesitant fuzzy sets, study the properties of the measurs. In the end, we develop an approach for multi-criteria decision making under dual hesitant fuzzy environment, and illustrate an example to show the behavior of the proposed distance measures.
