基于可变模糊决策模型的EPC项目总承包商选择研究

结合水利EPC项目的特点,从业绩、信誉、组织管理等角度出发构建指标体系。在此基础上,借助于灰关联分析和层次分析法确定组合权重向量,建立可变模糊决策模型。结合工程实例,利用可变模糊决策选择模型计算EPC项目总承包商的综合优属度,并对EPC总承包商进行优劣排序,选择出具有投标资格的总承包商。研究表明,可变模糊模型应用于业主方选择EPC项目总承包商中切实可行,能够为总承包商选择提供有价值的参考依据。

Variable fuzzy decision-making model-based study on selection of lump-sum contractor for EPC project

Combined with the characteristics of EPC project of water conservancy，an index system is constructed from the aspects of performance，reputation，organization management，etc. On the basis of this，a variable fuzzy decision-making model is established by means of determining combined weight vector with the grey relational analysis and the analytic hierarchy process. In accordance with an actual engineering case，the comprehensive subordinate degrees of the lump-sum contractors for the EPC project are calculated with the variable fuzzy decision-making model，while the competencies of the lump-sum contractors for the EPC project are sorted and then the lump-sum contractors with the bidding qualification are selected. The study shows that it is feasible to apply the variable fuzzy decision-making model for the owner to select the lump-sum contractors for the EPC project，which can provide a reference basis for selecting the lump-sum contractor.
