A Tower Plant Project Schedule Management, Applied Research, The Theory Of Constraints And Critical Chain

Bottle-neck exists anywhere, especially in projects. We always undertake many steel tower projects which include many kinds of bottle-neck factors. Due to the impacts of conflicts and these factors of technology and resources, which are called constraints, many projects are postponed. If managers want to finish the project in time, they have to lower quality standards. In traditional project scheduling management, although all tasks of the project have much safety time, but most projects still delay because of the impact of student syndrome and Parkinson's Law.Accounting for these problems, we review traditional methods for scheduling management with theory of constraints and critical chain method in contrast. The critical chain method considers both technology constraints and resource constraints among processes. The method lowers uncertainty effect on project plan with time buffers, known as the project buffer, the feeding buffers, and the resource buffer. It is illustrated by an example of real tower that the representative methods, theory of constraints and critical chain, emphasize system viewpoint, which can reduce the impact caused by some uncertain factor, and then reduce project time limit greatly and assure project quality effectively.
