Research on value-added mechanism of hydraulic engineering with EPC general contracting mode based on DEMATEL-ISM(基于DEMATEL-ISM的水利工程EPC项目价值增值机理研究)

Abstract

Nowadays, the applications of engineering-procurement-construction (EPC) general contracting mode in hydraulic engineering projects are increasing. And it will benefit EPC general contractor in value management by exploring the value-added mechanism. Firstly, this paper studies the value chain of hydraulic engineering, and identifies the value-added factors through literature research and expert interviews. Then the approach of questionnaire is applied to investigate the influence degree among each factor, and their centrality and cause degree are obtained by analysis method of DEMATEL. On the above basis, this paper divides the factors into 6 layers by adopting the analysis method of interpretative structural modeling (ISM), hence builds the value-added path of hydraulic engineering project with EPC general contracting mode. The result will provide the inspiration for EPC enterprises to formulate strategies in value management and further research.(采用设计-采购-施工（engineering-procurement-construction，EPC）总承包模式的水利工程项目日益增多，研究其价值增值机理有利于总承包方做好项目的价值管理。从水利工程EPC项目的价值链分析入手，基于文献和专家访谈得到23个价值增值影响因素。采用问卷调查方式得到各因素间的影响程度评分，用决策实验和评估实验（decision-making trial and evaluation laboratory，DEMATEL）法计算了各因素的中心度和原因度，结合解释结构模型（interpretative structural modeling，ISM）对数据进行分析，将价值增值因素划分为6类，构建了水利工程EPC项目价值增值的递阶模型，探究和揭示了项目价值增值的路径和机理。研究结果对水利工程EPC总承包方制订管理策略有一定启示作用。)
