The Applied Research Of Critical Chain Method In Schedule Planning Of Taihu Ship Lock Project

Schedule management is one of the important factor in project management. Meanwhile,Schedule planning is the core of schedule management ,The quality of the progress of plans determines whether or not the construction enterprise could achieve the goal in resource management and contract performance, it has a crucial impact on the economic benefits of construction enterprises.At present, the vast majority of water projects use CPM / PERT represented by traditional network planning techniques to develop the project schedule ,Traditional project scheduling methods only consider the relationship between time constraints, putting the zero floating or the less work packages as the critical path.So in the practical application,the traditional techniques easily lead to the extension of project progress.Critical Chain Method is a project management method based on the Theory of Constraints (TOC). It concerns systematic relation of project consider the resource-constrained project schedule and personnel psychological factors, by setting the buffer to monitor the progress of the project.This paper analyzes the disadvantage of the traditional project schedule management, conducted in-depth analysis in critical chain project management and suggests to use it to improve the reliability, validity and stability of project schedule. This paper takes the ship lock as an example to solve the complex relationship between processes, schedule uncertainties,Using methods of calculating the amount of use of a buffer and buffer the decision-making trigger mechanism to address the critical chain process in the application of specific issues. Practice shows that the critical chain in hydraulic engineering project planning and implementation of management, which has a good prospect for use.
