Pourafshar, O; Barmayehvar, B; Esmaeilabadi, R and Asnaashari, E (2025) An integrated FAHP-SD model to assess and allocate of critical risks for public-private partnership transportation projects. International Journal of Construction Management, 25(6), pp. 605-623. ISSN 1562-3599
Abstract
The present paper aims to identify and evaluate risks in transportation projects carried out through public-private partnerships (PPP) and proposes a model for allocating critical risks among stakeholders. The study utilizes the fuzzy analytic hierarchy process (FAHP) to prioritize risks and a system dynamics (SD) approach to develop a causal model for risk allocation. Thirty risks are identified and categorized into five primary risk categories: government, financing, operational, social, and organizational. Operational risks are found to be the highest priority, followed by organizational, economic, political, and social factors. Using the Pareto principle, eight critical risks are identified. The proposed SD-based risk allocation model is applied to a case study of the Shiraz-Isfahan Freeway Project. The results indicate that the project can be completed within the set timeframe of six years, but it would incur a 46% higher cost than initially estimated if 62% of the risk of exceeding the financial limit is allocated to the employer. This study provides valuable insights into risks associated with transportation projects undertaken through PPP. The proposed model offers stakeholders an effective and efficient approach to allocate risks. By addressing these risks, stakeholders can enhance the success and efficiency of PPP transportation projects.

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
