Research on Risk Factors of EPC Consortium Based on Improved DEMATEL-ISM
From the perspective of judicial precedent,this paper extracted 22 risk factors through the case study,literature analysis and expert discussion of EPC consortium related documents in the"China Award Documents Network",constructed the risk impact system of EPC consortium,and combined the DEMATEL-ISM model with the Apriori algorithm to quantitatively analyze the relation-ship among the influencing factors.The results show that the improved model can reflect the objective relationship between the nodes of each factor:the 13 cause factors and 9 result factors of risk are de-termined,and a hierarchical structure model with 3 levels and 6 stages was built.Among them,trust cooperation risk and agreement risk of consortium are the key factors that lead to the risk of EPC con-sortium projects,and schedule risk and contract duration risk are the fundamental factors that lead to the risk of EPC consortium projects.The research results can provide reference for relevant parties of EPC consortium to take targeted preventive measures,and also provide a certain basis for risk man-agement and control of EPC consortium projects,and decision support for risk management.
