A construction project is often affected by some uncertain factors such as policy constraints, environmental factors
and resource conflicts, etc. In order to improve the accuracy of the progress schedule and reduce the construction costs，the
progress schedule of renovation of SKP Berth No. 10 was post-evaluated and the scheduled progress and its uncertain factors were simulated with the use of a discrete-event system simulation model. The results show that the modeled period of construc tion coincides with the practical period of construction and the feasibility of this method is verified. During establishing project plans，the dynamic and intuitive simulation modeling can be used to deal with the risk，the resource utilization plans and cost control plans can be made.
