Using fuzzy decision making for supplier selection in public procurement
نویسندگان
چکیده
We address the strategic issue of supplier selection in the public procurement sector. The aim of the paper is providing a decision making tool that mimics the intuitive behavior of the public tender committee in evaluating the (quantitative and qualitative) performance indices characterizing suppliers and yet results in a strict and transparent selection procedure, in accordance with governmental procurement regulations and requirements. After discussing the peculiarities and similarities of governmental purchasing with respect to the procurement of services and goods in the private sector, we formalize the process of supplier selection for public procurement. We apply to this decision problem a well-known fuzzy multiple criteria decision making approach, able to incorporate imprecise information in vendor selection while keeping the necessary transparency features requested in public procurement. We enlighten the characteristics of the presented technique by way of a case study involving an Italian public administration, showing the effectiveness and efficiency of the proposed method.
