The Research Of Agricultural Production Macro Decision Support System And Demonstration Analysis

The research of Agricultural Production Macro Decision Support System is the formal scientific research project for adapting to the change of agricultural production management system and management concept,realizing the scientification and modernization of decisions of agricultural production,and realizing the everlasting use of resources and sustainable progress of the agriculture. In the introduction of the paper,I demonstrate systematically the current internal and external situation of agricultural decision support system,and we find that there is not systematically research for the theory of agricultural production macro decision support system.In view of the status of the research on agricultural production macro decision support system,in the main body of this paper,the writer firstly probe into the theory of agricultural production macro decision support system,it includes the definition,basic characteristics,function,the theoretic frame structure of agricultural production macro decision support system and the structure of software. The writer designs four function modules and two base structure of software,these four modules are the resource management module,the optimization module of the system synthesis,the macro economic development level module and the information management module,the two base software structure is data base,model base and conversational system.In the processing of exploitation software,the writer puts forward the idea that translating the theoretic frame structure to software structure,and the thought of manufacture of agricultural production macro decision support system based on data warehouse is confirmed. The system has four parts,which are data warehouse management system,data mining management system,model management system and conversational system. Besides,the system is connected with the Internet,and realizes the fast exchanging the information on Internet. The exploit platform of the software system is on SAS 8.0 that is the international newest exploit platform for decision support system. The system frame builted in this way has the following characteristics:the amount of data in the system is large,the opening of the system is better,the function of management data is strong,it is easy to modify the parameter in the models,and the speed of information spreading is accelerated by connecting the internet.On the basis of completing the research of the theoretic of agricultural production macro decision support system,the writer carries through the demonstration analysis research for ChuangYe Farm,who has established the data houseware of agricultural production in ChuangYe Farm,and has completed the the grain yield forecast,agricultural products' price index forecast,disaster changing forecast,industrial production structure assessment by usingdata mining system,the simulation of livestock's population change,analysis of input and output,and the establishment of model of industrial structure optimization. It settles the base for full information support to agricultural production macro decision of ChuangYe Farm. The writer has written the using book of the agricultural production macro decision support system for ChuangYe Farm,the manager of agricultural production can complete the decision of macro agricultural production by refereeing the using book. The agricultural production macro decision support system has been using in ChuangYe Farm,it has been certificated by the leaders of ChuangYe farm. This proved that the system is practicality and accords with the realism's need.Using the system in realistic production proves that the system structure is reasonable,whose running speed is fast,the information support is abroad,the browse interface bases on the Internet can not only be easy for browsing bur also realizes the calculation. The computer and user are fused,and the system is easy to extend.
