An expert system for diagnosis of pests, diseases, and disorders in apple crops

Abstract

A prototype expert system is being developed to diagnose pests, diseases, and disorders in apple trees. The system has the dual aims of supplying diagnostic advice to apple growers and teaching students to diagnose problems effectively. Notable features of the system include: clear separation between heuristic knowledge and domain/real world facts, a flexible certainty factor system, and a user-friendly environment. © Crown 1989.
