Abstract: Flexible Manufacturing System (FMS) selection is a Multi-Criteria Decision-Making (MCDM) problem. To effectively select an FMS, several criteria need to be considered which may be objective or subjective. Objective criteria are quantitative (tangible) while subjective criteria are qualitative (intangible) in nature. As the assessment values have various types of vagueness, one cannot always use the classical decision-making techniques for such decision problems. Grey theory is one of the methods used to study uncertainty. In this paper, a fuzzy MCDM approach based on the concept grey theory has been proposed to systematically evaluate alternatives. A numerical example is used to illustrate the efficiency of the proposed approach.

Keywords: fuzzy MCDM; multicriteria decision making; FMS selection; grey relational analysis; membership function; uncertainty; flexible manufacturing systems.
