Research for the Risk Structure of Large Design Enterprise’s Projects Based on Hard System Methodology

In this paper, we use the analysis of the time, knowledge and logic attributes of the risk, furthermore, to define, recognize and classify it based on the identification of the risk of large design enterprise project. We also put forward the thought and basic methods of building hall structural system of complex project risks, using it to establish hall structure system of large design enterprise project risks and point out the support that the system will provide for the risk assessment and strategy choice.
