Research Of Select Classy-fingerpost And Decision-making On Development Scheme Of Dam

Choosing development scheme of Dam is one of the most parts of Dam scheme decision-making. Although we have made some very good operation scenarios, we can not choose the best one, or we choose the wrong one. All that will do bad to building of Darn. The key that how to choose scenarios is to set up a reasonable target system and select a good method. So the paper studied these problems as follows.The paper summarized the keystone, the process and the rule of choosing operation scenarios. By analyzing the associated factor of operation scenario in the joined blockage, the paper set up a target system of choosing operation scenarios, and made the criterion of every target. The target system was evaluated as comparatively reasonable.The paper decided to exert a colligated criteria decision making to choose by analyzing the common methods and the rule of choosing Dam building scenarios. Thereinto, improved AHP was adopted to calculate the power of every target ,the method not only overcomed the illegibility of the traditional nine-demarcation, but also overcomed the problem that the coherence needs to prove . and it had the goods of prompt, nicety and efficiency.The paper designed and realized the software of choosing development scheme of Dam. In order to test the correctness of the software, the paper selected three Dam building scenarios, and carried through choose on these. The example proved that the software was good to solve the quality and the efficiency of choosing Dam building scenarios.
