Incremental Operator Assistance Knowledge System - an intelligent aid for a general class of problems

A new approach for knowledge representation and inference is introduced and discussed in this paper which is applicable to a wide range of daily probl ems-practically for all the problems, where some 'strategy' for fault searc h and rectification is provided by an expert. The system is efficient even if this 'strategy'-that is, the general understanding of the actual problem -is weak. The theory finds its application in the ADAC project, correspondi ng to a problem raised by Circuit Foil, Luxembourg, a leader in the copper foil industry.
