An integrated method for ranking of risk in BOT projects

Mohsen Askari, Hamid Reza Shokrizadeh, Mahdi Naghdian


In BOT approach, the private sector is granted a concession to plan, design, construct, operate and maintain a project in a certain period of time and after that it should be transferred to the government. In this paper, at first the risks of the BOT projects are identified, then we rank the risks based on their severity and effect on project objectives (time, cost, quality, safety and environmental) by two methods, namely FTOPSIS and FSAW. In the next stage, obtained results by NGT method are integrated. Afterward, the occurrence and detection values of each risk are determined by experts and ultimately the risks are evaluated according to risk priority number (RPN) of failure mode and effect analysis (FMEA) technique. Finally, an example is shown to highlight the procedure of the proposed method at the end of this paper.
