Application of Fuzzy Theory in Contractor Risk Assessment under EPC Model
To meet the requirements for being geared to the international standards and to meet the demand for selfdevelopment of an enterprise, it becomes more and more common for an enterprise to execute EPC projects. The EPC model compares with the traditional contract model, the risk of general contactor is the biggest undoubtedly. Through the analysis of the EPC model to determine the risk source and loss of general contractor and then use the fuzzy comprehensive evaluation method to realize the quantization of the possibility of risk occurrence and risk loss. By the quantified possibility of risk occurrence and loss consequences to calculate the risk gene and get the risk quantized valve ultimately. The example shows that fuzzy comprehensive risk evaluation method can realize quantitative treatment of fuzzy and uncertain information and can practically and effectively evaluate the EPC general contractor's risk.
