| Sumario: | Due to the increase in urban life (especially Tehran) and environmental problems, there is a great need to implement urban sewerage projects. One of the most important things about these kinds of projects is risk management. In this study, at first we reviewed similar projects and interviewed experts to identify project risk. Then we analyzed them in two methods, Analytical Network Process and FUZZY VIKOR. Prioritized risks were very similar in both methods. In ANP method, each risk was ranked but in FUZZY VIKOR method, some of the risks that were slightly different were ranked in the same category. Risks such as delays in paying bills, delays in issuing municipal permits, and other high-ranking risks need to be planned and managed. The risk of delay in payment of status statements with the ideal value of 1 in the ANP method and also with the minimum values of S, R, Q 0.011,0.011,-0.032 respectively, in the FUZZY VIKOR method, ranked first in both methods. It should be noted that the risks were identified and rated at the time of writing this paper. There are some suggestions and advice at the end. |
