The Research Of Expert System On The Engineering Of Protected Horticulture

Aiming at rural technical personnel and farms knowledge lacking, protected horticultural engineering construction being unreasonable, the investment efficiency rate of the engineering low, National Ministry of Education establishes the important project, The Research of Intellectual Information System and Technology on Industrialized Agriculture, to overcome them. It is in this paper that the expert system on the engineering of protected horticulture, which is available in Shanxi province and adjacent area, is developed on the basis of summarizing knowledge, experience and data accumulated by experts in protected horticulture and protected horticultural engineering, mainly with computer technology and expert system theory.It is this research that overcomes the difficult problems which variable factors in system design are many and researches about their coupling property are few with using engineering-organism-economy united theory, which horticulture facility types are too many, standardization low and dimension diverse with delamination strategy, and which reasoning in decision -making subsystem is hard because rules are uncertain with using uncertain reasoning with weight.It is windows 95/98 that is taken as its develop platform. It is adopted for the programming that is the language of Visual Basic 6.0 and the method of Object-Oriented design. Through analyzing the requirements of users for protected horticultural information and protected horticulture construction decision-making, the expert system is composed of protected horticultural information counseling subsystem and protected horticulture construction decision-making subsystem. User interfaces are made up with visual design in friendly interfaces and conveniently operations.According to literature index, no report on research of expert system in the engineering of protected horticulture is found so far in our country. Therefore, the design and development on this system has practical meaning and appliance value. However the expert system is going to need to be advanced and perfected for the research capacity abundant and time inadequate.
