摘要

Fuzzy decision making becomes one of the most important approaches to solve vague and not well defined optimization problems. However, the resulting fuzzy problems are frequently complicated and difficult to solve. One effective way to overcome these difficulties is to explore the generalized concavity properties of these problems. In this paper, we introduce and study the concept of supp-Φ_1-concave and supp-Φ_1-quasiconcave fuzzy sets. Some useful composition rules are developed. Based on these composition rules and the generalized concave properties, the basic characteristics of fuzzy multiple objective decision making problem can be formulated and solved.
