An integrated fuzzy multi-criteria decision making method for manufacturing strategies selection

Potential of many new manufacturing systems is being roadblocked in many cases by the wrongful use of traditional justification methods. Since, these new systems can offer not only the financial benefits but also longer-term strategic benefits. Thus, piece-by-piece traditional justification approaches, overemphasising short-term saving in direct manufacturing costs rather than longer term company strategic benefits, need to be modified to be able to evaluate those benefits which are long-term and perhaps intangible. The study also presents a further step by introducing the concept of fuzzy set theory in overcoming the precision-based evaluation. Results from this approach present a better understanding of each alternative and an easier approach to decision makers for evaluating issues which cannot be precisely defined.
