The Application of Power Plant Construction Investment Estimation Based on Improved Neural Network by PSO

Using BP neural network estimate the investment of the power plant construction project is this paper´s innovative points. First we give the engineering characteristic factors of power plant construction project, then give the value of each qualitative index. Then use improved BP neural network by PSO to estimate the investment. From the result, we can see that is more accuracy and speedily than BP neural network algorithm. Lastly, we can get a satisfaction result. This can be guiding the project construction investment.
