A Survey of Case-Based Diagnostic Systems for Machines

Electrical and mechanical equipment such as gearboxes in an industrial robots or electronic circuits in an industrial printer sometimes fail to operate as intended. The faulty component can be hard to locate and replace and it might take a long time to get an enough experienced technician to the spot. In the meantime thousands of dollars may be lost due to a delayed production. Systems based on case-based reasoning are well suited to prevent this kind of hold in the production. Their ability to reason from past cases and to learn from new ones is a powerful method to use when a failure in a machine occurs. This enables a less experienced technician to use the proposed solution from the system and quickly repair the machine.
