Design of investment risk valuation model on subentry project of light track construction——investment risk analysis based on BP neural net
Liwen Chen · Computer Engineering and Applications Journal · 2008
The questionnaire survey cost datum from the first part of the Jin-Bin Light Track project and the statistic cost datum from this project and projects alike were processed to estimate the percents distribution of cost overspending on the subentry project and this kind of distribution caused by each risk factor.BP Neural Net Valuation Seed Model on the investment risk was constructed when the roadbed project was taken as an example with the neural net theory.It was helpful to valuate the investment risk of the second part project of the Jin-Bin Light Track and other city track projects which would begin as a effective quantified valuation model.It also prepared a promotion template for advanced valuation model with sufficient training sample.
