Research On The Investment Cost Allocation For Multi-purpose Hydro-engineering

Multi-purpose hydro-engineering is an important part of basic water conservancy establishments in our country, which works both in improving development of water resources and controlling disasters. It meets the strategic requirement of coordinately developing the economy and society well. Because multi-purpose hydro-engineering needs many investments and long construction period, some related departments, such as flood control, energy production, water logging treatment, irrigation, shipping, and environment protection etc, must participate in it together to make sure implementing the project efficiently. Fairly allocating the investment cost between these departments is in favor of choosing economic exploitation manner and scale, increasing veracity of economy analysis, and improving management of multi-purpose hydro-engineering. It also provides references for studying methods of raising and distributing engineering project capital, and making investment planning for various departments.There is no uniform method for multi-purpose hydro-engineering investment cost allocation. This dissertation will first introduce the fundamentals of several traditional methods recommended by correlative criterions, and then particularly compare their respective explicabilities and disadvantages. Based on applying the theory of n-person cooperative game in investment cost allocation process, the Non-separable Cost Gap method is brought forward. The differential square method which bases on probability and statistics theory is also discussed to synthetically analyze and work out coefficient of investment cost allocation for certain multi-purpose hydro-engineering.
