تعیین کمیت پیچیدگی پروژه های حمل و نقل با استفاده از فرآیند تحلیل سلسله مراتبی فازی

Transportation projects are increasingly complex. A systematic approach for measuring and evaluating complexity in transportation projects is imperative. Thirty six project complexity factors were identified specifically for transportation construction. Using factor analysis, this study deduced the six components of project complexity, namely sociopolitical, environmental, organizational, infrastructural, technological, and scope complexity. The Fuzzy Analytic Hierarchy Process (Fuzzy AHP) method was employed to determine the weights of the components and parameters of project complexity. Sociopolitical complexity was the most defining component of complexity in transportation construction. A complexity level (CL) was proposed to measure the overall project complexity. The application of the proposed approach was demonstrated in a case study of three transportation projects performed by a heavy construction company. As a quantitative measure CL enables managers to better anticipate potential difficulties in complex transportation projects. As a result, scarce resources will be allocated efficiently among transportation projects in a company’s portfolio.
