Abstract
A method of predicting deterioration in a mechanical device includes the steps of providing a health model for the mechanical device, the health model including a plurality of health states for modeling the mechanical device, receiving device data for the mechanical device, estimating values for the plurality of health states, based on the device data, predicting one or more events based on the health model and the device data, each of the one or more events affecting one or more of the plurality of health states, and generating a prediction of deterioration in the mechanical device from the estimated values for the plurality of health states and the one or more predicted events.
Claims20
A method of predicting deterioration in a mechanical device, the method comprising the steps of:
- a) providing a health model for the mechanical device, the health model including a plurality of health states for modeling the mechanical device,
- b) receiving device data for the mechanical device;
- c) estimating values for the plurality of health states, based on the device data;
- d) predicting one or more events based on the health model and the device data, each of the one or more events affecting one or more of the plurality of health states;
- and
- e) generating a prediction of deterioration in the mechanical device from the estimated values for the plurality of health states and the one or more predicted events.
A program product comprising:
- a) an event and deterioration prediction program configured to at least facilitate:
- providing a health model for the mechanical device, the health model including a plurality of health states for modeling the mechanical device,
- receiving device data for the mechanical device;
- estimating values for the plurality of health states, based on the device data;
- predicting one or more events based on the health model and the device data, each of the one or more events affecting one or more of the plurality of health states;
- and
- generating a prediction of deterioration in the mechanical device from the estimated values for the plurality of health states and the one or more predicted events;
- and
- b) a computer-readable signal bearing media bearing the event and deterioration prediction program.
A deterioration and event prediction system for predicting deterioration in a mechanical device, the system comprising:
- a memory configured to store a health model for the mechanical device, the health model including a plurality of health states for modeling the mechanical device, and
- a processor coupled to the memory and configured to at least facilitate:
- retrieving the health model from the memory;
- receiving device data for the mechanical device;
- estimating values for the plurality of health states, based on the device data;
- predicting one or more events based on the health model and the device data, each of the one or more events affecting one or more of the plurality of health states;
- and
- generating a prediction of deterioration in the mechanical device from the estimated values for the plurality of health states and the one or more predicted events.
