Youssef, M; Mohamed, M S E and Balah, A A S (2024) Fuzzy model for Libyan construction projects delivery system selection. International Journal of Construction Management, 24(6), pp. 643-650. ISSN 1562-3599
Abstract
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.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
