An evaluating system for invite bid of Chinese Books purchasing based on BP neural network

On the basis of the establishment of evaluation index for book procurement tender, an evaluating system of book procurement tender was presented based on BP neural network algorithm. This designed system increased the speed of algorithm and improved the performance of algorithm. The analytic hierarchy process method was used to generate samples of network, which used the advantage of BP neural networks effectively and avoided some human errors in the process of evaluation for book procurement tender. Simulation results showed that this system was satisfactory. It can overcome some disturbances coming from subjective determine of normal values and weights effectively in the process of evaluation and evaluate the suppliers objectively. Therefore, the system can be an effective tool for choosing proper suppliers during the book procurement tender in the library.
