The construction project delivery system may be traditional or non-traditional, dependent upon the project-specific requirements and construction industry climate. Many factors are to be considered when making a decision, making it a multi-criteria decision. At the first stage of a project, most selection factors are vague. The project delivery system selection influences all project stages. In the next decade for Libya, there is a tremendous need to adopt a Projects Delivery System (PDS), which avoids the adverse objectives and conflicts that have characterized the Libyan construction industry for too long. This paper aims to assist decision-makers in understanding these concepts better. By utilizing the Fuzzy model, based on proposed criteria assigned to delivery systems evaluation for Libyan construction projects and the opinion of experts, PDSs were evaluated. The study outcome is twofold. Firstly, it selects the proper criteria and explores a Libyan construction project delivery decision-making system based on the Fuzzy theory perspective. Then has ranked the project delivery systems for the Libyan construction industry as follows: 1st rank construction manager at risk, 2nd rank construction manager as an agency, 3rd rank design-build, and 4th rank design-bid-build system. This study can be a quick and effective approach for construction owners.
