摘要：The quality of large complex projects is more difficult to manage, because there are more quality interfaces and quality conflicts. This paper aims to explore the quality coordination approaches of large complex projects from the quality chain perspective, so as to reduce the quality conflicts. We firstly give the definition and operation mechanism of the macro quality chain with comparing the supply chain quality management and the quality chain management. The analysis results indicate the feasibility and necessity to introduce the quality chain management into projects construction management. The large complex project is divided into five importance levels that have critical control points respectively. Finally, based on the optimization concept model, the optimization measures of quality capability are concluded to designate the quality improvement directions. The research results may provide a new theoretical perspective and management support.
