Abstract:

 In order to achieve the comprehensive schedule risk management of grid project, based on enterprise risk management （ERM） framework, a comprehensive schedule risk management system was formed, which concluded five subsystems: target system, environment system, organization system, process system and method system. Meanwhile, it presented the risk research method with circular transmission. Further, based on the research framework, it explored the risk link relations on the base of a new concept of “risk map” and built a risk evaluation model, then quantified the impact of each risk value via fuzzy evaluation. Finally, key risk with higher degree of influence was obtained, which could provide a reference for risk prevention and control. 

Key words: enterprise risk management （ERM）, schedule management, comprehensive schedule risk management system, risk map, risk evaluation
