POMI: An Expert System for Integrated Pest Management of Apple Orchards

This paper describes an Expert System for apple orchard integrated control. The system consists of two parts. In the first one, help to the agricultural producer is provided in classifying the producer observations. In the second part an interactive abductive module suggests explanations of those observations. Classification has been implemented with the aid of discrimination net techniques. The abductive module exploits results from the parsimonious covering theory by Peng and Reggia. The system has been implemented in KEE with an extensive use of the graphical tools provided by the language. In a future work it will be extended with a module responsible for treatment suggestion. 1 Introduction The general reevaluation of ecological-environmental problems has increased interest in those forms of agriculture characterized by reduced environmental impact. In fact, the traditional model of agricultural development, based on massive introduction of innovative technologies, while allowi..
