Applying critical chain in project scheduling and estimating buffer size based on fuzzy technique

Project scheduling has long been an area of intensive research. Aiming at the problems in the current Scheduling Management based on classical network scheduling techniques, this paper analyzes the principles of the theory of critical chain and the applications in project scheduling management, and discusses the principles of project buffer under the comparison of critical chain and classical network scheduling techniques. However, in the real world, project activities are subject to considerable uncertainty, which affects the performance of project scheduling management. A fuzzy method is researched to estimate the buffer size in critical chain scheduling to reduce the uncertainty degree. The test results indicate the evaluation based on fuzzy technique can improve the performance of project schedule. The future works are mentioned in the end.
