Study On Intelligence Decision-making Support System Of Rice Production

The study of this system is a part of national 863 program "study and application onintelligent agriculture information processing system development plat" and the significentscience and technology special program of hefei city "study and application on intelligentagriculture information network technology ".The research object of this system is oneseason rice of Anhui province, and the goal of this system is to achieve high yield,goodquality,high efficiency of rice production, integrated knowledge and experiments of ricecultivation,plant protection,soil fertilizer,agricultural ecology. etc. field experts, adoptedmultidisciplinary crossing and organic combination, combine information experts andagronomy experts,and construct it by from macro to micro,qualitative to quantitative.This system combine qualitative analysis of expert system and quantitative analysis ofdecision support system based on models, overcome their limitations and play theiradvantages respective, with logic reasoning judgement,decision-making ability and higheraccuracy and reliability. This research of the system is based on objected-oriented component technology andintegrated environment of xiongfeng expert system development tool. The system is madeup of decision-making before sowing(variety selection,fertilizer preparing),sowing seededseeding management,growth and development stages management,diseases,pests,weedsdiagnosis and protection,nutrition diagnosis,etc, subsystem. Encoding of knowledge baseadopt productive rule expressing knowledge of expert system, at the same time add somemodel datum to rules or the calling models directly, made the expert system which madeaided decision-making using qualitative analysis and decision support system which madeaided decision-making based model date system using quantitative analysis combinedorganically, enhance ability of adaptbility analysis and decision-making of expert system,provide right decision-making basis for variety selection and cultivation management of aseries of rice production technology link. The system has characteristics as follow: 1.Rich content of knowledge base, combining sound,pictures,words. The knowledgein base come from agricultural field experts, and demonstrated again and again,selectedand integrated, rich and full-scale knowledge and deserve believing, encoded byprofessional engineers, with high structure degree and utilization efficiency. Knowledgebase is combined qualitative reasoning and quantitative compute , and integrated pictures,flash,video and lot of kinds hypermedia knowledge, form of representation expressionflexible,vivid. 2.The system is integrated agriculture expert system,decision-making support systemand multimedia technology ,which is intuitional , visual , friend interface ofperson-computer,simple and convenient to use and operate, easy to learn and tounderstand. 3.Realization remote decision-making through intelligence decision system andnetwork technology integrating. Development tool xiongfeng 7.2 is a new generationexpert system development plat based on component system structure, which make systemto distribute reasonably and flexibly in terms of users' need. Maintenance, updatingconveniently. Providing decision-making consultant service for many users throughnetwork to satisfy agriculture technology service need of network form.
