Résumé
Pinus sylvestris cultivate expert systems integrate a large number of expert knowledge and practical experience , in close connection with the actual production , in accordance with Pinus sylvestris seedlings production process into functional modules , each module within the project ’s decision-making scientific and meticulous , and throughout the whole process of seedling . The system interface is good , simple operation, users do not need the higher operating skills , and is conducive to the production units at the grassroots level applications , and real-time query and master Pinus sylvestris nurture scientific knowledge and technology to provide information services and decision support for forestry units and users , guide the seedling the nutrition bag seedlings and commodity the large seedlings intensive production operations . The National Agricultural Information Engineering Technology Research Center, and defense, University of Science and Technology jointly developed PAID expert system development tool . This paper briefly describes the workflow of the platform architecture , knowledge representation and reasoning mechanisms . The system is the knowledge base of production representation , performance problem solving class knowledge in the form of rules , each rule contains the premise and conclusion of its weight and credibility , and the Uniform Code stored in the rule base . System inference mechanism credibility of the method to indicate uncertainty reasoning . User selected fact table , the system automatically will correspond to the project ’s decision-making , and data entry date displayed reasoning produce reasoning results and show the reasoning process of decision - making project . Decision-making is complete , the user can view and print the reasoning process , where the reasoning process used in rules , the system automatically extracted to allow the user to view the interpretation of that rule .
