Project management concept and method are used in almost every work by a growing number of organizations; estimate the size of time buffer is the essence of Critical Chain Project Management. The paper use queuing theory to solve the size of time buffer of resource constrained Critical Chain Project Management. And then carry out the economic optimization analysis from the profit of the queuing system to determine the optimal size of time buffer. It can guide enterprises to rationally determine the project cycle, to use project resources effectively; and more effectively deploy and standardize the process of project implementation. Meanwhile, we discuss the existing difficulties in Critical Chain Project Management as well as future researches.
