【Abstract】 In this paper, the application of neural network in expert system, the design methods and system structure of neural network expert system are advanced. At last, some technological details for system realization are discussed. Theoretical basis of genetic algorithm and BP neural network andintegration methods of genetic algorithm, neural network and expert system, are discussed in this dissertation. Mineral processing expert system using genetic neural network in the dissertation is an important innovation, with great theoretical and practical significance. It can enrich the research methods on mineral processing expert system. Based on genetic neural network, the idea of building model is advanced, the genetic neural network models for predictionof ore beneficiability, flow-sheet selection and flotation production targets are built. The methods of original data pre-processing, the design of BP neural network, and some parameters selection are studied. Through verification of production examples, the prediction accuracy has achieved over 90%. ;更多还原
