THE EXPERT SYSTEM OF PINK BOLLWORM MANAGEMENT IN COTTON AND ITS REALIZATION

The expert system has been constructed to help extension staff or cotton planter forecast population of pink bollworm of cotton (PBW), diagnose PBW problems in their locat area, and determine recommendations on control strategy, time and methods. It is a great success to use mathematics models, historal data and experts' experance in the system. The system designed and realized with AIPROLOG computer logic logic language, composed of seren parts knowledge base, model pool, explanatory part, in- ference engine, knowledge capture part, data management subsystem and dialogue part between person and the system. A joint between the computer language PROLOG and C was developed in the system, which raised efficiency of quautitative and qualitative analysis of the system. Knowledge in this system was represanted by rule of IF (certain conditions are true) THEN (certain conclusious are true) with variable. The system has been run in DaFeng (Jiangsu Provence) to prove its validation and the rate of accurancy to forecast PBW population was over 95%.
