EPC项目的综合性、复杂性和特殊性要求项目总承包商在技术、管理、财务等方面都要具有很强的实力,这也就决定了业主选择EPC项目总承包商的重要性。从业主角度出发,建立了EPC项目总承包商选择评价指标体系,构建了基于Vague集的选择模型,该模型利用Vague集的相似度量原理能有效地对备选承包商进行优劣排序,选择出进入投标程序的总承包商。 The comprehensiveness, complexity and particularity of the EPC project require that the project general contractor has strong technical, management and financial aspects, which determines the importance of choosing the EPC contractor as the owner.
