Since variety of construction projects with their individual specifications could be handled through different procurement systems, selection of the most appropriate project delivery system is a vital step towards more efficient project execution as well as competent management of the project. The appropriate selection of project delivery system not only influences first stages of the project, but it could also impact pre-construction, construction and operational phases of the project. Among different approaches exerted for this purpose, none has taken uncertainty into account, despite the fact that during first stages of the project most of the selection factors are not clearly defined. This paper, hence, aims to have a fuzzy insight into the project delivery system selection so as to provide more tangible model of the evaluation process. Proposed fuzzy method is indeed a multi criteria decision making model, based on the group of criteria assigned for the evaluation procedure. A case study is also conducted, based on the opinion of an invented group of the experts.
