A triangular fuzzy number approach to multiobjective vendor selection problem

Vendor selection is a multi-criteria decision making problem influenced by multiple performance criteria. In this paper, a multi objective vendor selection problem is addressed through the creation of fuzzy Pareto optimal set and its satisfactory level. Each objective function is transformed into a set of three objective functions. The solution (Simonovic and Verma(2008)) is obtained by using positive and negative ideal solutions and a set of weights, in form of triangular fuzzy number, assigned to the objective functions. The optimization problem has been taken from Yucel and Guneri (2011) to illustrate the methodology. Results show that the degree of satisfaction is 0.5 from the view point of a moderate decision maker.
