Abstract

A method includes monitoring a system for fault conditions, determining an estimated energy loss based on the fault condition, determining an estimated product loss and/or sales loss based on the fault condition, and scheduling maintenance to correct the fault condition. Maintenance is schedule to correct the fault condition prior to the energy loss and the product loss exceeding maintenance costs.

Claims

1. A method comprising:

monitoring a system for fault conditions;

determining a maintenance cost to correct said fault condition;

determining a monetary value of said fault condition;

comparing said maintenance cost to said monetary value; and

scheduling maintenance based on said comparison.

2. The method of claim 1, wherein said determining a monetary value includes determining at least one of an additional energy cost associated with said fault condition, a product loss associated with said fault condition, and a sales loss associated with said fault condition.

3. The method of claim 1, further comprising performing said maintenance if said monetary value exceeds said maintenance cost.

4. The method of claim 1, wherein said scheduling includes listing said maintenance with all other maintenance requests.

5. The method of claim 4, further comprising bundling said maintenance with said other maintenance requests based on said comparison.

6. The method of claim 5, further comprising completing said bundled maintenance at one service call.

7. The method of claim 1, wherein said monitoring includes electronic monitoring.

8. The method of claim 1, wherein said monitoring includes manual monitoring.

9. A method comprising:

monitoring a system for fault conditions;

determining an energy cost based on said fault condition;

determining a product cost based on said fault condition; and

determining a maintenance cost based on said fault condition; and

determining a time in which to correct said fault condition based on said energy cost, said product cost, and said maintenance cost.

10. The method of claim 9, wherein said product cost determination includes determining product lost due to said fault condition and sales lost due to said fault condition.

11. The method of claim 9, wherein said maintenance cost determination includes determining labor cost, parts cost, and travel time associated with correcting said fault condition.

12. The method of claim 9, wherein said time determination includes subtracting said product cost from said maintenance cost.

13. The method of claim 12, further comprising scheduling maintenance to correct said fault condition if said subtraction yields a time value equal to, or less than, zero.

14. The method of claim 12, further comprising delaying maintenance to correct said fault condition if said subtraction yields a time value greater than zero, said time value indicating a time in which to complete said maintenance.

15. The method of claim 12, further comprising dividing the difference between maintenance cost and product cost by said energy cost.

16. The method of claim 15, further comprising scheduling maintenance to correct said fault condition if a result of said division yields a time value that is less than a predetermined time value.

17. The method of claim 15, further comprising delaying maintenance to correct said fault condition if said division yields a time value greater than a predetermined time value, said time value indicating a time in which to complete said maintenance.

18. The method of claim 9, wherein said monitoring includes electronic monitoring.

19. The method of claim 9, wherein said monitoring includes manual monitoring.
