Food safety is one of the hot issues in all over the world. It is related to national economy and people's livelihood. In recent years, food safety accidents occur in China frequently, so an effective food safety network public opinion early warning model is necessary and imperative. Therefore, the model of Back Propagation neural network based on Analytic Hierarchy Process (AHP-BP) is proposed. The...
For the reason of the complexity of software projects and the uncertainty of software risk factors, it is difficult to use a mathematical expression to represent the model of risk assessment. It belongs to the classification of nonlinear. In this paper, we established the evaluation model of software project risk based on BP neural network. Firstly, an evaluation index system of software project risk...
