Research on Project Schedule Method of Critical Chain Method

Abstract

The critical chain method proposed by the bottleneck resource thought based on TOC is a new method of project management. This paper first introduces the background of the development of critical chain method and the research situation at home and abroad from the critical chain method. Secondly, critical chain method and PERT/CPM are compared in five aspects: different understanding of the resources, different understanding of the organizational behavior, different views on the risk, the disagreement in the network plan and the determination of the critical path, and the improvement of the critical chain method to the PERT/CPM is obtained. Finally, a simple list of the two critical chain buffer size calculation methods, so as to further deepen the study of the critical chain method.
