Maintenance management of a machine
First Claim
1. A method of providing maintenance management of a machine comprising:
- identifying a machine component failure that if not repaired will result in a functional failure of the machine;
assigning a criticality factor to the machine component failure based on at least a probability of occurrence of the functional failure and a consequence of the functional failure to a machine user;
generating a maintenance task to repair the machine component failure;
defining a triggering condition that activates the maintenance task;
conducting a machine repair in response to a detection of the triggering condition;
maintaining a record that includes information relating to the conducted machine repair;
calculating performance indicators based on at least the record, the performance indicators including at least a work order backlog indicating a number of open work orders; and
modifying the method of providing maintenance management based on at least the calculated performance indicators.

Abstract
Methods of providing maintenance management of a machine are disclosed. In one embodiment, the method involves identifying a machine component failure that, if not repaired, will result in a functional failure of the machine. A criticality factor is assigned to the machine component failure based on at least a probability of occurrence of the functional failure and a consequence of the functional failure to a machine user. A maintenance task is generated to repair the machine component failure, and a triggering condition that activates the maintenance task is defined. The method further involves conducting a machine repair in response to a detection of the triggering condition, and maintaining a record that includes information relating to the conducted machine repair. The method of providing maintenance management is also modified based on at least the record.

18. A method of providing maintenance management for machines located at geographically separated worksites comprising:
-
classifying a failure of at least some of the machines based on a criticality of the failure to a functioning of the worksite, the machines including multiple first machines located at a first worksite and multiple second machines located at a second worksite geographically separated from the first worksite; comparing the failures of the first machines to the failures of the second machines; developing a predictive maintenance task based on the classification; developing a preventive maintenance task based on the classification; scheduling the preventive maintenance task to perform maintenance of a plurality of the first machines or a plurality of the second machines at a same time; scheduling the predictive maintenance task to perform maintenance of a plurality of the first machines or a plurality of the second machines at a same time, where the preventive task and predictive task are scheduled during other planned machine downtime; maintaining a record that includes information related to the performance of the maintenance; calculating a performance metric based on the record; and modifying the method of providing maintenance management based on at least the performance metric. - View Dependent Claims (19, 20, 21, 22, 23)
