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;
generating with the data processor an upgrade requirement if the actual configuration is noncompliant and storing the upgrade requirement in a third database in the storage device; and
executing with the data processor 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updating the actual configuration and the desired configuration prior to expiration of the limited duration to avoid an outdated configuration.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 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.
