Using fuzzy decision making for supplier selection in public procurement

The paper addresses supplier selection in the public procurement sector. The motivation is providing a decision-making tool that mimics the intuitive behavior of the public tender committee in evaluating the bid according to predefined (quantitative and qualitative) criteria by a strict and transparent procedure, in accordance with governmental procurement regulations and requirements. To this aim, we address the supplier selection decision problem in the public procurement sector by a well-known fuzzy multiple criteria decision- making approach. Using the presented technique enables evaluation of both imprecise information and quantitative data in vendor selection, while keeping the transparency features requested in public procurement. We show the effectiveness and efficiency of the approach with a case study involving an Italian public administration.
