| The paper presents research and development production of wheat Expert System for Shanxi Province. After we are analyzing foreign and domestic agriculture ES, resolution has been demonstrated in details. The system has used ASP, ES and Database technology and can be accessed.The paper puts forward a solution of the system that consists of production information management and intelligence decision-making subsystem. In intelligence decision-making subsystem, following technologies are discussed: knowledge representation method based on fuzzy production rules; forward and backward chaining; approximate reasoning based on ANN model, which great success has been achieved especially in the resolution of complexity and fuzzy facts of agriculture knowledge. Besides, the idea of realization of reasoning machine by FNN combining fuzzy reasoning with neural net is presented, and the process of fuzzyreasoning is worked by using the structure of PDP. Moreover, a new reasoning algorithm based ANN is offered to improve efficiently the performance of the wheat system. |
