Risk Evaluation Of Urban Rail Transit Project Of PPP Mode Based ISM-ANP-Grey Clustering

Urban rail transit projects of PPP model with the amount of large, long cycle, complex and diverse characteristics, determine its own risk is also large, over the entire life cycle of the project is accompanied by risks.Meanwhile, urban rail transit projects of PPP model have public welfare, generally.Therefore, in-depth study and research urban rail transit project of PPP model risk management is important.Combined with domestic and foreign construction project risk management research status and related outcomes, describes the preliminary definition of the Urban rail transit project of PPP model risk management, and analysis of PPP Mode in Urban Rail Transit project risk characteristics and classification, and then discusses the Urban rail transit project of PPP model risk factors, in particular.Refer to the relevant literature, according to theoretical evaluation index system construction, incorporating the principles and methods of systematic reviews constructs containing the total risk, urban rail transit project of PPP model Risk Evaluation System guidelines layer and evaluation, where total risk is highest risk, guidelines for the second layer level risk.Then, according to the characteristics of the Urban rail transit project of PPP model risk, based on interpretation of the structural model (ISM), network analysis (ANP) and gray clustering, the first clustering index weight, and then the parameters of a comprehensive evaluation, Construction the PPP mode urban rail Transit project risk evaluation model based on ISM-ANP-gray clustering, enhanced evaluation results and scientific credibility. And examples of analysis to verify the rationality of this model.Methods used in this paper that the information collected to maximize the role model calculates concise, scientific and reasonable results.Based on interdependence ISM method to identify risk factors, so that the present model of the evaluation process more consistent feature of human thinking, so that the calculation process more maneuverability. Through this article we know, ISM-AHP- gray clustering method is an effective way to solve the PPP mode Urban Rail Transit Project Risk Management.
