摘要
本文阐述了企业供需网概念,并对总承包商在供需网环境下的分包商选择流程进行设计,突出建筑分包商选择对建设项目顺利完成的重要影响。分析企业供需网环境的网络性、多功能性、开放性以及动态稳定性的四项基本特征,在此基础上探讨其对建筑分包商选择指标建立的影响及应遵守的体系构建原则。运用层次分析法(AHP)建立建筑分包商选择指标的层次结构模型,构造判断矩阵区分准则层与子准则层的不同权重,再将AHP与数据包络分析法(DEA)结合,利用组合权系数向量确定决策单元的"输入"和"输出",建立DEA的模型来评价同类分包商的相对有效性。最终实现主观考量与客观因素对各分包商进行权重与相对效率的综合判断,提高了建筑分包商选择的可靠性。
This article illustrates the concept of supply and demand network of enterprises with multi-function and opening characteristics（SDN） and designs the selection process of the general contractor for subcontractor in the SDN environment,which can highlight the important influence of the subcontractor selection for a successful project completion. The SDN characteristics of global networks, multi-functions, fully opening and dynamic stability are discussed. Based on this, influence factors and principles for the establishment of selection index are analysised. Then,the hierarchy structure model for construction subcontractor selection is established. A method of combining AHP with DEA is proposed to judge the relative efficiency of each subcontractor. Finally, it realizes the comprehensive judgment of subjective and objective factors to consider the weight and the relative efficiency of each subcontractor,which could improve the reliability of construction subcontractor selection.
