Abstract

Supplier assessment has been a vital issue of strategic importance in a supply chain. It helps to reduce operating cost, improve competitiveness and to develop business opportunities. However, supplier selection is usually a complex and unstructured activity, involves the consideration of various characteristics simultaneously such as large number of alternatives, multiple criteria involved in the evaluation process as well as group of experts with diverse backgrounds. This study intends to propose a framework using interval type-2 fuzzy (IT2F) TOPSIS method for selection of suitable suppliers in an imprecise environment for an Indian spare parts manufacturing company. Seven important criteria are considered for evaluating suppliers. A practical analysis is carried out and the data are collected from a set of five prospective suppliers. The major influencing factors in the case company are found to be price of product, technological capability, relationship closeness, conformance to quality and experience of supplier.
