Abstract
Nowadays multiple criteria have been added to the decision making procedure as a result of the harmonization of Greece’s public procurement to EU guidelines (i.e. 72/62/EC, 93/36/EC and 80/67/EC). The main objective of the research is to propose an evaluation methodology as a group decision framework for this problem. In doing so a systematic procedure is introduced based on Delphi technique aiming to evaluate the capability of grouped vendor suppliers to deliver the project as per the owner's requirements. The order of the tenders is derived by comparison of the tenders’ efficiency. A case study is used as an example from a procurement case in Greece using criteria indices namely the Risk management, Quality of work, Price certainty, Time availability and predictability, Technical capacity of tenderers, Regularity of Environment, Energy intensity of building operation, Economic and Financial capacity of tenderers, Familiarity of tenderers of a building project. The results strengthen the opinion that the Delphi method paired with discriminant analysis is a powerful and appropriate technique for deriving objective solutions in categorization of procurement cases and is a rather subjective area such as the procurement system for vendor selection. This research outlines a process by which the traditional tenders’ selection using discriminant analysis method can be improved via the utilization of a Fuzzy Delphi Method (FDM), a cross-mutation of the traditional Delphi Method (DM) and fuzzy logic (FL).
