This paper studies critical chain method(CCM) used for project management. By using CCM and based on the model of resource-constrained project scheduling problems (RCPSPs), a CCM project scheduling model is developed. To make the critical chain project plan, firstly this paper presents a priority-based scheme, in which the active plan can be produced based on the priority list, and then the unique critical chain can be defined. Regarding feeding buffers as dummy tasks and re-scheduling the project plan, the resource conflict problems produced in embedding feeding buffers are resolved. A hybrid genetic algorithm approach is designed to search the optimal task priority list for solving the CCM project scheduling model. Finally, the effectiveness of the model and its solution is verified by simulation experiments.
