Diagnosis of Equipment Failures by Pattern Recognition

The main problems in relation to automatic fault finding and diagnosis in equipments or production systems are discussed: 1) compression of the syndrome and observation spaces for better discrimination between failure modes; 2) simultaneous display of the failure patterns and the failure instants, for maintenance control and review of the reliability design; 3) automatic production of a final set of diagnosis assumptions classified according to their probabilities. 4) sequencing of the inspections in accordance with the failure rates and inspection costs.
