Performing predictive maintenance based on a predictive maintenance target
First Claim
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 noncompliantestablishing 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updating the actual configuration and the desired configuration prior to expiration of the limited duration to avoid an outdated configuration.

Abstract
A method and system for performing predictive maintenance on an item of equipment comprises establishing a desired configuration of the item of equipment based on a predictive maintenance target of the item of equipment. The predictive maintenance target may include at least one of a functional configuration objective, a logical configuration objective, and an operational configuration objective. An actual configuration of the item of equipment is monitored. It is determined if the actual configuration complies with the desired configuration. An upgrade requirement is planned for upgrading the actual configuration to the desired configuration if the actual configuration is non-compliant.

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. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
