Abstract

A computerized system for performing predictive maintenance on an item of equipment includes a desired configuration database, an actual configuration database and a data processor. The data processor determines if an actual configuration complies with a desired configuration. The data processor determines an upgrade requirement for upgrading the actual configuration to the desired configuration if the actual configuration is noncompliant. The data processor further defines an interim solution that eliminates delay in the execution of the upgrade requirement on the item of equipment.

Claims

1. A method of performing predictive maintenance on an item of equipment, the method comprising the steps of:

establishing a desired configuration of the item of equipment based on a predictive maintenance target of the item of equipment;

wherein the predictive maintenance target includes at least one of a physical configuration objective, a functional configuration objective, a logical configuration objective, and an operational configuration objective;

wherein the functional configuration objective of the item is consistent with meeting a performance metric of a group of equipment;

subjecting items of the group of equipment to more frequent predictive maintenance than other items of the group of equipment or prematurely retiring the items from service in accordance with the performance metric;

evaluating an actual configuration of the item of equipment;

determining if the actual configuration complies with the desired configuration;

planning an upgrade requirement if the actual configuration is noncompliant

establishing a real-time procedure comprising;

changing the actual configuration, the desired configuration and the upgrade requirement with time;

maintaining the actual configuration and the desired configuration on a selected item of equipment valid for a limited duration; and

updating the actual configuration and the desired configuration prior to expiration of the limited duration to avoid an outdated configuration.

2. The method according to claim 1, wherein the establishing comprises defining the logical configuration objective as a decision to substitute a generally suitable replacement component for an existing component of the item, rather than repair the existing component.

3. The method according to claim 1, wherein the establishing comprises defining the logical configuration objective as a decision to repair an existing component, rather than substitute a generally suitable replacement component for an existing component of the item.

4. The method according to claim 1, wherein the establishing comprises defining the logical configuration objective as a decision to repair a component, rather than to replace the component in kind.

5. The method according to claim 1, wherein the establishing comprises defining the logical configuration objective as a decision to replace the component in kind, rather than repair a component.

6. The method according to claim 1, wherein the establishing comprises defining the operational configuration objective as a measured response of the item to at least one operating requirement and an associated operating environment.

7. The method according to claim 1, wherein the establishing comprises defining the operational configuration objective as a measured response of a component of the item to at least one operating requirement and an associated operating environment.

8. The method according to claim 1, wherein the establishing comprises defining the operational configuration objective as a measured response of a system of the item to at least one operating requirement and an associated operating environment.

9. The method according to claim 1, further comprising enhancing the reliability of the item by incorporating redundant components into the desired configuration.

10. The method according to claim 1, further comprising enhancing the reliability of the item by incorporating a self-healing system into the desired configuration.

11. A system for performing predictive maintenance on an item of equipment, the system comprising:

a desired configuration database for storing a desired configuration of the equipment based on a predictive maintenance target of the item of equipment;

wherein the predictive maintenance target includes at least one of a physical configuration objective, a functional configuration objective, a logical configuration objective, and an operational configuration objective;

wherein the functional configuration objective of the item is consistent with meeting a performance metric of a group of equipment;

wherein items of the group of equipment are subjected to more frequent predictive maintenance than other items of the group of equipment or prematurely retired from service in accordance with the performance metric;

an actual configuration database for storing an actual configuration of the equipment based on an evaluation of the equipment; and

a data processor determining if the actual configuration complies with the desired configuration, the data processor determining an upgrade requirement for upgrading the actual configuration to the desired configuration if the actual configuration is noncompliant, wherein the data processor further defines an interim solution that eliminates delay in the execution of the upgrade requirement on the item of equipment, the interim solution covers time periods after a noncompliance with the desired configuration is detected and prior to placing the actual configuration in conformity with the desired configuration, and the interim solution requires restricted usage of the item of equipment whose actual configuration does not comply with the desired configuration and requires provisional operational training of human resource.

12. The system according to claim 11, wherein the logical configuration objective is defined as a decision to substitute a generally suitable replacement component for an existing component of the item, rather than repair the existing component.

13. The system according to claim 11, wherein the logical configuration objective is defined as a decision to repair an existing component, rather than substitute a generally suitable replacement component for an existing component of the item.

14. The system according to claim 11, wherein the logical configuration objective is defined as a decision to repair a component, rather than to replace the component in kind.

15. The system according to claim 11, wherein the logical configuration objective is defined as a decision to replace the component in kind, rather than repair a component.

16. The system according to claim 11, wherein the operational configuration objective is defined as a measured response of the item to at least one operating requirement and an associated operating environment.

17. The system according to claim 11, wherein the operational configuration is defined as a measured response of a component of the item to at least one operating requirement and an associated operating environment.

18. The system according to claim 11, wherein the operational configuration objective is defined as a measured response of a system of the item to at least one operating requirement and an associated operating environment.
