Research on marketing risk early-warning system based on FA-BP evaluation model

Marketing risk early-warning system is based on evaluation. Integrating fuzzy and neural network, marketing risk FA-BP (fuzzy Accurate -Back Propagation) evaluation model is built. Appling fuzzy logic inference, expert knowledge is introduced to measurement course, which makes that measurement system can solve nonlinear and uncertain problem. Moreover, self-study, self-adoption and generalization ability of neural network make system accomplish the circulation work, realizing intelligence of measurement. Probability is applied to partition risk degree.EI
