Evaluation Method of Hydropower Project Investment Decision-making

The evaluation methodology depends upon experts' subjective experiences excessively and treats the data strictly,which is applied in the investment decision-making of hydropower project at present.Meanwhile,there's no uniform standard for choosing evaluation index.Maximal uncorrelated method is used to analyze multiple correlations of the evaluation indexes for investment decision-making of hydropower project.And then it eliminates the evaluation indexes which have larger complex correlation coefficients.The evaluation decision-making system is built with simplified indexes.Finally,the fuzzy probability theory is applied to establish the fuzzy probability model of hydropower project investment decision-making.The application results show that the modified evaluation model overcomes the limitations of choosing evaluation index weight in practice.So,it is obviously rational and widespread used.
