Abstract :
A learning component that has been incorporated into the transmission line troubleshooting system (TLTS), a knowledge-based system which implements a model for performing redesign, is presented. The model was applied in the domain of redesigning circuits which are laid on printed circuit boards. The knowledge of TLTS is organized in a blackboard architecture. The learning component can form new knowledge sources from redesign knowledge. It does this by compiling the knowledge that is contained in redesign plans that the user creates in cooperation with TLTS. The learning component also acquires redesign metaknowledge for selecting the most appropriate knowledge source to redesign a faulty circuit. It does this by utilizing the problem-solving information that is generated by TLTS and cooperating with the user
