Analyzing and Controlling Construction Engineering Project Gray Rhino Risks with Innovative MCDM Methods: Interference Fuzzy Analytical Network Process and Decision-Making Trial and Evaluation Laboratory

Construction engineering projects are costly and require large amounts of labor, physical, financial resources. The failure a construction project typically brings huge losses. Previous studies have focused on the identification risks, but insufficient attention has been given to strategic resource allocation for risk management after identification. Statistics show that most failures caused by common risks. Common risks called gray rhino This metaphor illustrates many obvious dangerous. study was motivated challenge efficiently managing with limited inputs. literature suggests abundant in there mutual eliciting relationships between them, which make it difficult manager devote enough resources prevention key Considerable wasted unimportant resulting occurrence projects. Therefore, this describes an innovative multi-criteria decision making (MCDM) technique ranking based strength them. used fuzzy created interference analytical network process (IF-ANP) method. By employing IF-ANP alongside decision-making trial evaluation laboratory (DEMATEL) approach, subjectivity can be effectively reduced accuracy improved during expert quantify DEMATEL rank result. An empirical done meticulously five were selected from Chengdu–Chongqing Middle Line High-speed Railway project. They capital chain rupture, failure, policy legal risk, economic downturn, stakeholder conflict. results showed source other these symptoms rather than disease.
