Hydraulic Engineering Project Economic Evaluation Base On System Dynamic

Hydraulic engineering project is a long duration, high investment, involving a wide range of technical complexity of the natural transformation project, It is the process of economic and social development irreplaceable foundation support is to improve the ecological environment of the indispensable support system. With China’s booming infrastructure construction, Hydraulic engineering project construction also ushered in a busy period of development. In order to make water projects can get better economic avoid irrational investment and scientific decision-making, etc., it needs to project economic evaluation. Economic evaluation of the construction project is an important basis for a reliable decision.Hydraulic engineering construction and operation and social economic influence each other and form a complex system, the entire system has dynamic, complex, multi-feedback and other characteristics. So, we will be system dynamics as a research tool, the Hydraulic engineering project’s personnel, materials, machinery, finance, the environment and a series of complex factors and systematic model, from the perspective of the overall system, the establishment of a economic evaluation model system based on Hydraulic engineering system dynamics. Through computer simulation to analyze the dynamic changes of Hydraulic engineering project investment and operation, understand the impact of changes in various factors on the project and brought to predict problems that may arise.This paper focuses on financial analysis, The use of model building for construction and operation of L hydropower stations actual simulation, Through the analysis of simulation data, it can learned changes of projects profit, solvency and net present value in dynamic, to make judgment of the project economically rational, next, sensitive analysis the project, in order to know key factors how to effect the viability of the project. Using the system dynamics assess hydraulic engineering economics is not only economic evaluation of a new attempt on the research tool, but also a reliable basis for decision-making water projects of a new exploration.
