Abstract: This paper extends the Weighted Euclidean Distance Based Approach (WEDBA) to the fuzzy environment in MCDM. Fuzzy concepts are introduced, in which alternative ratings and criteria weights are described by linguistic terms. WEDBA features the usage of integrated criteria weights, objective and subjective, which enhances its performance and overcomes the drawbacks of methods that only use one type of weight such as AHP and TOPSIS. Two examples are provided to highlight the procedure of the proposed method named Fuzzy WEDBA. The first example is a fuzzy MCDM problem, which aims to evaluate five suppliers of an automotive production company. The second is a real-life case study to select a contractor for a construction project. A comparative analysis is conducted based on several factors. The proposed method has greater time complexity, due to using integrated criteria weights, but performs similarly to F-TOPSIS in most of the evaluation factors, and both perform better than F-AHP with regard to the remaining factors.

Keywords: WEDBA; fuzzy; TOPSIS; AHP; supplier; contractor; selection; MCDM.
