Risk Management of Urban Pipe Gallery Based on System Dynamics

Abstract Under the background of continuous urbanization in China, urban underground comprehensive pipe gallery will become an inevitable trend of urban comprehensive management in the future. After the completion of the management gallery, how to effectively manage the risks in operation and maintenance management has become a topic at this stage. Based on the classic method of AHP combined with DSM method, and through a lot of literature research, to build the relationship between the risk of an integrated pipe rack system, and has carried on the system dynamics simulation using Anylogic software, finally, the simulation results obtained a few of comprehensive pipe gallery has the greatest effect in the overall risk of several risk paths, convenient operational phase in the pipe gallery risk in the future, you can draw on the results of several path for more effective management.
