Abstract

The aim of this paper is to present an evaluation process using OWA operator in fuzzy Multi-attribute group decision making (MAGDM) technique for helping the health-care department to choose a suitable diagnostic laboratory among several alternatives. In the process of decision making, experts provide linguistic terms to evaluate each of the alternatives, which are parameterized by generalized triangular fuzzy numbers (GTFNs). Subsequently fuzzy MAGDM method is applied to determine the overall performance value for each alternative (laboratory) to make a final decision. Finally, the diagnostic laboratory evaluation problem is presented involving seven evaluation attributes, five laboratories and five experts.
