采用约束理论对建筑项目工程造价进行分析,将对关键的极少数因素进行系统调控,找出影响工程造价超支的少数决定性因素,把这些因素所在的制约环节变为能显著改善工程造价控制的杠杆,主张改善瓶颈环节的功能,对于不紧迫的非瓶颈环节可以暂缓考虑达到有效控制建筑项目工程造价的目的。 Using constraint theory to analyze the construction project cost, we will systematically control and control a handful of key factors to find the few decisive factors that affect the project cost overruns, and turn the constraints of these factors into the lever that can significantly improve the project cost control , Advocating the improvement of the function of bottleneck link, the non-bottleneck link of non-pressing can be suspended for the purpose of effectively controlling the construction cost of the project.
