Abstract: Traditional planning methods focus on critical path but neglect some uncertain factors which affected production planning. This would extend production cycle, decrease finishing rate and delay products delivery. To solve these problems, a new multi-project planning method called Key Chain Planning (KCP) was proposed by combining theory of constrains, critical chain and Web technology. This method considered human factors and resources constrains in the project management. To avoid influences caused by human or other risk factors, ideas of improving process pre-calculating time, eliminating process buffer time, as well as setting up project buffer and ability buffer were proposed. Then the KCP method was used to conduct scheduling in the bottleneck and non-bottleneck flexibly. The Monte arol simulation models were constructed for Critical Path Method (CPM)/Project Evaluation Review Technique (PERT)-based project planning and KCP-based project planning by the Crystal Ball software. The simulation result verified KCP's feasibility.
