Regarding the current situation and problems,which exist in Modular Dispatch dynamic programming system that is widely used in open-pit truck real-time dispatching,two concepts for the completion of production target and the current truck flow saturation were proposed,and based on which the guideline of real-time optimized open-pit truck dispatching method was dissertated.

By analyzing and extracting the newest researches on lint yield and yield components in cotton, a dynamic knowledge model for decisionmaking on yield target and yield components was developed by integrating the effects of climatic conditions, soil fertilities, management levels and variety types.

The framework and content of rice N fertilizer application decision making based on method of fertilization for target yield by means of soil information system were introduced and the results of a preliminary study of Dafeng City,Jiangsu Province were showed.
