Hybrid supplier selection methodologies: Problems and perspectives

This paper presents a hybrid model for coping with the supplier selection problem, based on the combination of the two main approaches proposed in the extant literature, the Analytic Hierarchy Process (AHP) and Fuzzy Set Theory (FST). The proposed model combines the strengths of the two approaches, overcoming some of their weaknesses. An empirical study is provided, to check t he usability and the usefulness of the developed approach in a real-life context.
