Supplier selection is crucial as it involves in-depth research process whereby multiple criteria should be considered. With the rising cost of raw materials and products, the management is forced to make better choices when selecting supplier. This paper proposed a fuzzy evaluation technique by using fuzzy linguistic terms in selecting the best IT supplier based on certain criteria. Fuzzy grade matrices...
Ranking of fuzzy numbers is an important procedure for many applications in fuzzy theory, in particular, decision-making. In this paper, we propose a new method for ranking fuzzy numbers based on Dice set theoretic index. The Hurwicz criterion which considers all types of decision makers' perspective is employed in aggregating the fuzzy total evidences. The properties of the proposed method are also...
The fuzzy evaluation method which used fuzzy linguistic variables throughout the procedure and aggregated the fuzzy numbers based on the standard score concept has been proposed by [1]. The method applied the centroid concept in ranking the alternatives. Although the centroid concept which is a class of mapping fuzzy numbers into single point or known as defuzzification is relatively simple and easy...
