Risk element transmission model of construction project chain based on system dynamic

This study aims to study the dynamic risk transmission process through project chain among multi projects, which means the risk of one project would influence other projects through project chain. Based on system dynamic, a model of risk element transmission in cost-period chain between 2 construction projects is established and then accordingly studies how the risk element influences the other project. At last an example is simulated by using system dynamic software and the final effect on other project result from risk element transmission is calculated, under which the risk managers would take reasonable risk response measures for risk management. Besides, the simulated result of model provides strong support for using system dynamic to do research on risk element transmission.
