Identification and Evaluation of Construction Projects’ Critical Success Factors Employing Fuzzy-TOPSIS Approach

The construction industry is a significant motive for the economic and industrial developments in countries. Consequently, the success of the construction projects is crucial for any country because the failure of these projects imposes extreme costs to the economic and industrial development of the country. Thus, the identification of the critical success factors of the construction projects and ranking these factors has a major role in the success and failure of the projects. In this study, the critical success factors are determined through the survey of the literature, and the set of critical success factors are considered as options. After that, a questionnaire was prepared with respect to the criteria such as time, cost, quality, and safety, which are the measurements of the success and failure of the projects. This questionnaire was distributed to the professionals and experts of the construction industry that form the statistical population to determine the percentage of approval and importance of each criterion. Then, the Fuzzy TOPSIS multiple criteria decision-making methods have been used to rank the critical success factors of the construction projects. Finally, a comparison of proposed method and Entropy-based Fuzzy Multi-MOORA has been shown. According to the research results, the level of the effect of each critical factor on the successful execution of Iran’s construction projects will be provided.
