Abstract

A computer implemented method may be used for analyzing equipment failures and maintenance schedules. An equipment maintenance system generates a model of equipment and components of each piece of equipment. In one embodiment, the model is a tree representation. The equipment maintenance system may then determine estimated failure information for each component based on a selected statistical model. The equipment maintenance system may also generate a maintenance schedule based on the determined estimated failure information for each component of the equipment. In one embodiment, the equipment maintenance system displays the equipment maintenance information.

Claims34

Dependent claims

A computer-implemented method for displaying equipment failure estimation information comprising:

receiving information, utilizing a first user interface displayed on an equipment maintenance system, relating to maintenance of a plurality of components of at least one item of equipment, wherein a source of the information includes a database;
generating, using a processor, display data indicative of a tree representation of the components;
receiving data, utilizing a second user interface displayed by the system, indicative of a selection of a portion of the tree representation;
receiving, utilizing a third user interface displayed by the system, an assignment of a statistical model to at least one of the components corresponding to the selected portion of the tree representation, wherein the third user interface is configured to receive an assignment of a first statistical model for one portion of the tree representation and a second statistical model for another portion of the tree representation;
and
estimating equipment maintenance information associated with at least the selected portion of the components based on the assigned statistical model.
