Research on the Application of TOPSIS Method in EPC Risk Assessment

TOPSIS method, as a relatively new comprehensive evaluation method for multi-objective decision making, makes use of the proximity between the evaluation object and its ideal target to rank the relative advantages and disadvantages, and is a comprehensive evaluation method for intra-group distance. This method is often combined with risk identification technology in the field of risk assessment, which can accurately reflect the gap between evaluation schemes, correctly identify risks, assess risks and scientifically control risks, reduce adverse effects and improve management level, so it is widely used in the engineering field. As the infrastructure construction tends to be saturated and the industry competition becomes increasingly fierce, the project construction mode is gradually changing from the traditional mode to the EPC mode. EPC projects have the characteristics of large construction scale, many personnel and mixed technologies, and are faced with complex risk factors in the construction process. Therefore, it will become a trend to explore the better integration of EPC projects and TOPSIS method. This paper mainly discusses the advantages and disadvantages of TOPSIS method, research status and applicability with EPC, proposes my own views on the improvement of TOPSIS method in EPC projects, and looks forward to its future research direct0069on in the field of risk assessment, so as to provide references for the integration and improvement of EPC projects and TOPSIS method.
