Computer Prediction Forecast System Theory And Applied Research

This article researches on the computer prediction and forecast system,it does the system research on the computer prediction and forecast method in the agricultural plant disease aspect application,the article also has done technical analysis research of computer prediction and forecast realization on four aspects:expert system knowledge expressing,the principle of computer prediction and forecast system,the application appraisal models in computer prediction and forecast system and the application technology in computer prediction and forecast system,finally,taking the potato blight disease prediction and forecast system as an example,it proposes the most superior plan on prediction and forecast aspect,provides the technical support for instructing farmers scientific farming,realizing agriculture production increase and the farmers receive increase.The main research work and the achievements of this article is:Through the expansion of the frame language,it joins the defining relation and the rule expression,makes the union of the production pattern and the frame on the expression and use of the knowledge.Through the understanding and the analysis of many kinds of the computer prediction and forecast system models,it summarizes the proper method on the construction of prediction and forecast models,and the uses the frame language describing the domain main body.It designs potato blight disease prediction and forecast system,it can get the information of potato blight disease and transform it to the knowledge library. The system provides the man-machine interaction,the analysis to the user input symptom information,and gives the forecast result,the expert suggestion as well as the manage information to the user.
