查询词典 Monte Carlo

The integrated risk between hydraulic, hydrologic uncertainty and the construction scheduling uncertainty should be analyzed. The paper puts forward the risk analysis model for the construction scheduling and the risk analysis model for construction diversion on the assumption that the construction scheduling is affirmable. Thus the Monte-Carlo method is used to simulate the integrated risk of construction diversion system considering hydraulic, hydrologic uncertainty and the construction scheduling uncertainty.
