Maintenance planning and failure prediction from data observed within a time window

摘要

A system for predicting a failure of equipment from prior maintenance data of the equipment collected during a time duration estimate a number of preceding failures of the equipment prior to the time duration. The system constructs a model, based on the prior maintenance data, of an impact of an external intervention on a failure of the equipment. The system constructs a model, based on the constructed model of the impact of the external intervention and the estimated number of preceding failures, of a replacement policy of the equipment and a probability of a subsequent failure of the equipment in a subsequent time period.
