Abstract
In this paper, the S‐Curve membership function methodology is used in a vendor selection (VS) problem. An interactive method for solving multi‐objective VS problems with fuzzy goals is developed. The proposed method attempts simultaneously to minimize the total order costs, the number of rejected items and the number of late delivered items with reference to several constraints such as meeting buyers’ demand, vendors’ capacity, vendors’ quota flexibility, vendors’ allocated budget, etc. We compare in an industrial case the performance of S‐curve membership functions, representing uncertainty goals and constraints in VS problems, with linear membership functions.
