The Invest Decision Based On Bayes On Highway Bot Project

Highway construction is an infrastructure, it requires large amount of capital. So it is important to analysis, forecast, statistics, comprehensive evaluate, and find the source of their risk before the BOT project investment decision-making. It provides a scientific and accurate prediction and judgment, also it provides a scientific basis for decision making for the future project.And with the development and scientific progress, we need the accuracy and reliability of risk evaluation. To address this issue, the paper, based on Bayesian network BOT project investment risk assessment methods carried out in-depth research. Based on the existing research results ,the paper describe standardized the characteristics of BOT project investment risk, creatively establish the norm of index system of investment risk and according to the norm establish the index system of investment risk, combining of fuzzy mathematics adopting the method of combination of qualitative and quantitative, establish methods of risk evaluation basing on Bayesian network, analysis the BOT project investment risk from the macro-and micro-angle, effectively solve the BOT project investment decision-making uncertainty and complexity; and through the two BOT road projects verify the method scientific.
