Research And Implementation Of The Potato Breeding Expert System

This article is passed collecting large amount of potato field knowledge, with the comparatively current expert system technology, having set forth detailed researching and realizing process of the potato breeding expert system. By adopt Windows DNA module technology which based on COM/COM+, have realized the potato breeding expert system with three layers (presentation layer ,business logic components and data services layer) of software framed structure, diminished the expert system's design degree of difficulty, improved the compatibility after systematic. And have carried out broad investigation and discussion on the technology developing owing to the frame software technology.During the period of reasoning system establishing of the expert system, have studied the contradiction conflict solve tactics middle of reasoning process in a deep-going way , brought forward the conflict solve tactics basis on Analytic Hierarchy Process method and Fuzzy Synthesis Judgment. When the knowledge base is ample, regulation similarity degree is bigger, join the user and expert's together decision-making thought in the process of reasoning, made an effect solution to the conflict. In structuring process, we argue strongly arrangement of ideas is limpid, explanation is detailed, in order to achieve this goal, this paper arranges contents as follows.First, give out basic theory about artificial intelligence , knowledge engineering , expert system and intelligent system , then introduce that the agriculture develops condition at home and abroad of agriculture expert system, under the big banners of developing vigorously in northeast China brought forward by Party and the government in recent years, think to the agriculture important position in developing vigorously and potato estate is hit by the pillar effect in northeast China economy, bring forward the subject content and the main job.Secondly, compare the building tools, Database and run platform, choose the programming implement being suitable to self, database, and the minimum request of running platform .make a detailed description about the mathematics theory and software engineering relating to the subject. And then, make a detailed theory constitution and designation in progress about the express way to knowledge of expert system, knowledge acquisition mechanism , reasoning mechanism, control tactics and data base design etc.Lastly, carried out the system which designed by theory in software method, have effectively testified the correctness of theory designs. The pragmatism is appraised, sufficiently testified the software pragmatism value and the subject correctness .
