Predictive maintenance display system
First Claim
1. A maintenance display for predicting the optimum date on which components in a system are to be serviced, comprising:
- a sensor system for monitoring a parameter indicative or an operating condition of at least one of the components in the system;
an Equipment Failure And Degradation Module that receives an input from the sensor system and from the sensor system input determines if the component monitored in the system is in imminent danger of failing and the predicted remaining component life the monitored component; and
a probability of failure predictor module that determines and displays, for a specified date, the probability that a failure in the monitored component will occur prior to the specified date.

Abstract
A display system in which subsequent failures of plant equipment and plant systems are predicted to occur and in which the probability of failure before a specified date and the probability of failure after a specified date is determined and displayed and in which the calendar date is determined and displayed when the desired probability that the equipment not fail prior to the calendar date is specified. The system includes an Equipment Failure And Degradation Module that determines the remaining equipment/system life; a Probability-of-Failure Predictor Module that determines the probability of the equipment/system failing prior to a specified date and the probability of the equipment/system failing after a specified date; and a Date-of-Failure Predictor Module that determines the calendar date that corresponds to a specified probability that equipment not fail prior to the date.
