Abstract

ABSTRACT In the present study, an appropriate risk assessment and allocation model was developed between the various elements of PPP based infrastructure projects. For this purpose, after a review of the research literature and identification of the most important risks, with a case study on PPP-based freeway projects in Iran, a systematic model for risk assessment using fuzzy MCDM methods including FAHP has developed in order to critical risk assessment (Objective 1), FTOPSIS Identification of Common Risks in PPP Transportation Projects (Objective 2) and FDEMATEL for Allocation and Impact of Risk Between Different Project Elements (Objective 3). The results of risk analysis by FAHP method showed that economic and financing, construction and operational risks have the greatest impact, respectively. In addition, the results of FTOPSIS method showed that projects Isfahan-Shiraz Freeway, Salafchegan-Arak Freeway and Khorramabad-Arak Freeway, respectively, were more affected by risks. Finally, the results of FDEMATEL analysis show the degree of interaction and impact strength of risks for each risk and from the perspective of each project manager, which indicates a significant relationship between different risks. The results of this research can be used as a management model in the process of evaluation and risk management of PPP projects.

基于模糊多准则综合决策技术的公私合作模式下高速公路项目各要素风险分配模型

摘要在本研究中，在基于PPP的基础设施项目的各个要素之间建立了一个适当的风险评估和分配模型。为此，在回顾了研究文献并确定了最重要的风险后，通过对伊朗基于PPP的高速公路项目的案例研究，开发了一个使用模糊MCDM方法（包括FAHP）进行风险评估的系统模型，以进行关键风险评估（目标1），FTOPSIS确定PPP交通项目中的常见风险（目标2）和FDEMATEL确定不同项目要素之间的风险分配和影响（目标3）。采用FAHP方法进行风险分析的结果表明，经济和融资、施工和运营风险分别影响最大。此外，FTOPSIS方法的结果表明，伊斯法罕-设拉子高速公路、萨拉夫切根-阿拉克高速公路和Khorramabad-Arak高速公路项目分别受到更大的风险影响。最后，FDEMATEL分析的结果显示了每个风险的相互作用程度和风险的影响强度，并从每个项目经理的角度来看，这表明不同风险之间存在显著的关系。本研究的结果可作为PPP项目评估和风险管理过程中的管理模型。
