Abstract
Evaluation of supplier relies heavily on previous experiences and human judgments which are vague and uncertain. Fuzzy approach has been applied extensively to deal with subjectivity, using fixed fuzzy numbers corresponding to its linguistic values. However, these fuzzy numbers do not necessarily reflect actual respondents’ opinions. This paper proposed a two-phased fuzzy multi-criteria decision making method in selecting supplier. First, triangular fuzzy numbers were developed based on respondents’ rating on the appropriate scale of 0–100 for seven-scale linguistic terms. Then, fuzzy evaluation method was applied to rank the best supplier based on three main criteria. Results from a case study in an Information Technology (IT) department showed that Supplier 1 is the best supplier among the four supplier candidates. It is hoped that the evaluation results via these fuzzy numbers gave a significant meaning towards their decision making.
