An expert system has been developed which forms the basis of a management procedure for weaving problems, the objective being to find the reason for each incident and to keep in a memory all the information concerned. Every weaving problem would thus be detected, indentified and filed. The system incorporates as easy dialogue facility at several levels as well as a systematic and precise diagnosis of the incident. The exploitation of the global data thus obtained might well pave the way to a true mastering system of both the productivity and the quality in a weaving mill. The expert system will be specially useful in modern high productivity weaving mills, where the investment cost per worker is high; furthermore the relevant data could be read online during the cloth inspection.
