Analytic hierarchy process was applied to risk identification,fuzzy probability-fault tree analysis to risk probability assessment,statistics and analogy process to risk consequences assessment, lastly, grey relevant analysis and comprehensive index process to risk impact evaluation. The main environment risk accident of the project is dam failure, the main causative factors of the accident are catastrophic flood and wrecking earthquake. The flash flood, due to dam failure, will impact on nature, society and economy. The major environment risk areas are Jingzhou and Xiangfan,Hubei Province. The environment risk management measures should be adopted in order to ensure the safety of the project-environment complex system.展开更多

The approach is to take the water source as a constraint on the regional economic development, calculate the difference between the generaded when the water source project is in operation and the gross product generated when the project is nonexistent, and then review the economic benefits on the project. For this purpose, we have constructed an input-output linear programming model and compiled a compatible using the routines for solving the input-output linear programming model. The above models and the routines have been used in paractical calculation of economic benefits of a water source project for a region. The computation result are satisfactory.展开更多
