The success or failure of a project depends on the adoption of a suitable Project Delivery System (PDS). This paper presents an integrated Fuzzy AHP Multi- Criteria Group Decision Making (FMCGDM) approach for the project delivery system selection. The proposed approach can select the best PDS option based on the opinions of a heterogeneous group of experts. The relative weights of decision criteria as well as their scores are evaluated using Analytic Hierarchy Process (AHP) technique. The criteria weights and scores assigned by di erent decision makers are aggregated and converted to a fuzzy number. The relative weight of decision makers is determined using a new fuzzy logic based method. Finally, the score of each PDS option is determined as a fuzzy number by the use of Zadeh's extension principle and performing interval arithmetic at discrete -cuts. To evaluate the performance of the proposed method, it is implemented on a real dam and hydropower plant project.
