This study advances a project duration risk transmission model based on CCPM and the generalized project risk element transmission theory. By combining the calculation of systemic duration risk of a single process and the transmission of duration delay through an activity chain, this study proposes an modified method of calculating and setting input buffer and project buffer and also distinguishes the bottleneck activities on both the critical chain and non-critical chain, this method can offer a more reliable basis for making a project schedule plan and duration risk control.
