| 1. A predictive maintenance method for an item of equipment, the method comprising:
establishing a first business module as a first resultant business framework for supporting maintenance work on the item of
equipment, the resultant business framework comprising at least three feature modules including:
a prediction module determining predictive maintenance as part of the maintenance work based on an actual discovery of a maintenance
need from inspection of the equipment, estimation of the maintenance need from a current performance evaluation of the equipment,
and a forecast of the maintenance need from historical performance evaluation of the equipment,
a resource availability module comprising temporal data and related geographic data of resources for performing prospective
predictive maintenance activity; and
an integration module comprising a scheduler integrating the prediction module and the resource availability module;
selecting first core elements for the first business module required for performing the maintenance work on the item of equipment
wherein the core elements comprise modular constituent parts of the first business module, and wherein desired features of
the first business module determine the first core elements and define functions of the first core elements, the first core
elements including;
a performance data manager in the prediction module managing storage and retrieval of performance standard data indicative
of a measurable achievement of a required specific task of the maintenance work within a specified time limit; and
an availability data manager in the resource availability module managing storage and retrieval of availability data, the
availability data including worker data, facility data, tool data and component data for performing the maintenance work;
organizing the first core elements into the first resultant business framework of a first provider of the maintenance work;
establishing an additional business module comprising additional core elements as an additional resultant business framework
of an additional provider of the maintenance work;
integrating and linking the first core elements and the additional core elements across the first business module and the
additional business module for allocation of human resources, test equipment, maintenance tools, components, infrastructure
and a facility for performing the predictive maintenance included in the maintenance work; and
executing the established first business module by predicting with the prediction module, and as part of the maintenance work,
a first required maintenance activity on a first component and a second required maintenance activity on a second component
by:
prior to performing either of the first and second required maintenance activities, identifying the first component and the
second component as suspect components of the item of equipment when first component performance data, received from an equipment
sensor, and second component performance data, input at a prediction module user interface, deviate from a defined performance
standard;
flagging the first component and the second component of the item of the equipment with a suspect status;
clearing the suspect status of the first component in response to an acknowledgement input at the prediction module user interface
prior to initiating performance of the first required maintenance activity;
determining a preliminary maintenance schedule for performing the second required maintenance activity on the second equipment;
and
wherein executing the established business module further comprises scheduling performance of the second required maintenance
activity for the item of the equipment with the scheduler by:
determining a first revision to the preliminary maintenance schedule, the first revision specifying substitution of an alternate
component for the second component of the item of equipment; and
generating a resultant maintenance schedule based on the preliminary maintenance schedule and the first revision.
