Automatic maintenance estimation in a plant environment
First Claim
1. A method of automatically scheduling maintenance orders within a process plant comprises a plurality of assets, the method comprising:
- generating a maintenance order in response to a maintenance alert for at least one of the plurality of assets;
generating estimated maintenance information for the maintenance order, the estimated maintenance information indicating an estimated time or an estimated cost associated with the maintenance order;
communicating the estimated maintenance information to a maintenance scheduler for scheduling the maintenance order among a plurality of other maintenance orders; and
scheduling the maintenance order based on the estimated maintenance information, the scheduling resulting in a maintenance schedule that includes the maintenance order.

Abstract
A maintenance system for a process plant collects and uses historical data about maintenance orders. The data identifies the maintenance items for completing an order, such as the labor, materials, and maintenance tasks required. The data is historical data developed from actual completed maintenance orders. The system uses archived historical data and estimates various maintenance information, such as estimated cost for completing the maintenance order, and estimated start and completion times. The estimated data may be based on averaged data as a result. This estimated data along with the other maintenance order information may be sent to a scheduler for identifying a priority to the maintenance order and scheduling it accordingly.

18. A method of automatically scheduling maintenance orders within a process plant, the method comprising:
-
generating a maintenance order in response to a maintenance alert for an asset in the process plant, the maintenance order comprising maintenance items for completing the maintenance order; receiving actual data on the maintenance items; receiving estimated maintenance information on the maintenance items; comparing the actual data and the estimated maintenance information to generate estimated maintenance information for the maintenance order, the estimated maintenance information indicating an estimated time or an estimated cost associated with the maintenance order; generating a maintenance schedule including the maintenance order and based on the estimated maintenance information. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26)

27. A system to be used in a process control environment for estimating a maintenance order, wherein the process control environment includes a plurality of devices, the system comprising:
-
a computer readable memory; a first set of instructions stored on the computer readable memory and adapted to be executed on a processor to generate a maintenance order in response to a maintenance alert for one of the plurality of devices; a second set of instructions stored on the computer readable memory and adapted to be executed on a processor to generate estimated maintenance information for the maintenance order, the estimated maintenance information indicating an estimated time or an estimated cost associated with the maintenance order; a third set of instructions stored on the computer readable memory and adapted to be executed on a processor to communicate the maintenance order to a maintenance scheduler; and a fourth set of instructions stored on the computer readable memory and adapted to be executed on a processor to develop a maintenance schedule prioritizing the maintenance order based on the estimated maintenance information. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41)
