【Abstract】 This paper researches multiple attribute synthetical evaluation problems with Error Back Propagation Training artificial neural network(BP neural network).To comment the mark is the background to invite tenders by the construction project item, BP’s models of the multiple attribute synthetical evaluation have been established,lead the additional momentum law and become the long algorithm of step,transform to BP’s neural network algorithm,and by which study training speed has been greatly raised.This paper uses this kind of neural network to solve the real problems,and gives the result of it.更多还原
