Abstract

An equipment operating status tracking system is provided, which may include a graphical user interface (GUI), a processor, and a computer-readable medium operatively coupled to the processor. The computer-readable medium may include a memory in which are stored instructions for receiving operating status data for at least one piece of equipment and automatically, initially categorizing any downtime in the operating status data as uncharacterized. The computer-readable medium may include instructions for displaying at least some of the operating status data, including the uncharacterized downtime, to a user authorized to characterize downtime. Further, the computer-readable medium may include instructions for receiving input from the authorized user to characterize the downtime by selecting from a plurality of characterization categories, each category being indicative of a different cause of downtime. In addition, the computer-readable medium may further include instructions for displaying the characterized downtime.

Claims

1. An equipment operating status tracking system, comprising:

a graphical user interface (GUI);

a processor; and

a computer-readable medium operatively coupled to the processor and including a memory in which are stored instructions for;

receiving operating status data automatically collected for at least one piece of equipment;

automatically, initially categorizing any downtime in the operating status data as uncharacterized;

displaying, on the GUI, at least some of the operating status data, including the uncharacterized downtime, to a user authorized to characterize operating status data;

receiving input from the authorized user to characterize the downtime by selecting from a plurality of characterization categories, each category being indicative of a different cause of downtime; and

displaying the characterized downtime on the GUI.

2. The system of claim 1, wherein the characterization categories indicate whether the downtime is planned, unplanned, or caused by a problem with something other than the equipment from which data is collected.

3. The system of claim 1, wherein the computer-readable medium further includes instructions for:

determining availability and reliability of the equipment by using the processor to process characterized operating status data to generate availability and reliability data; and

displaying the availability and reliability data on the GUI.

4. The system of claim 3, wherein the availability and reliability of a piece of equipment during a time period is determined by the processor only if all operating status data collected during the time period has been characterized.

5. The system of claim 3, wherein the availability of the equipment is determined for a time period by subtracting planned downtime and unplanned downtime from the total amount of time in the time period and dividing by the total amount of time in the time period.

6. The system of claim 3, wherein the reliability of the equipment is determined for a time period by subtracting unplanned downtime from the total amount of time in the time period and dividing by the total amount of time in the time period.

7. The system of claim 1, wherein the characterization categories include two or more different categories of unplanned downtime, each unplanned downtime category corresponding to a different component of a system incorporating the at least one piece of equipment from which operating status data is automatically collected.

8. The system of claim 1, wherein the computer-readable medium further includes instructions for:

automatically, initially categorizing any time with missing operating status data as uncharacterized;

displaying, on the GUI, at least some of the uncharacterized time with missing data, to a user authorized to characterize downtime;

receiving input from the authorized user to characterize the time with missing data by selecting from a plurality of characterization categories, each category being indicative of a different operating status; and

displaying the characterized time with missing data on the GUI.

9. The system of claim 1, wherein the at least one piece of equipment is a fleet of equipment including pieces of equipment at two or more facilities;

and

wherein a fleet manager responsible for managing operation of the fleet of equipment is the only entity with authorization to characterize the operating status data of the fleet.

10. The system of claim 1, wherein the computer-readable medium includes instructions for displaying and receiving information regarding characterized and uncharacterized operating status data via a web-based interface.

11. A method of tracking operating status of equipment, comprising:

receiving operating status data for at least one piece of equipment onto a computer-readable medium;

using a processor operatively coupled to the computer-readable medium to automatically, initially categorize any downtime in the operating status data as uncharacterized;

displaying, on a graphical user interface (GUI), at least some of the operating status data, including the uncharacterized downtime, to a user authorized to characterize downtime;

receiving input from the authorized user to characterize the downtime by selecting from a plurality of characterization categories, each category being indicative of a different cause of downtime; and

displaying the characterized downtime on the GUI.

12. The method of claim 11, wherein the characterization categories indicate whether the downtime is planned, unplanned, or caused by a problem with something other than the equipment from which data is collected.

13. The method of claim 11, further including:

determining availability and reliability of the equipment by using the processor to process characterized operating status data to generate availability and reliability data; and

displaying the availability and reliability data on the GUI.

14. The method of claim 13, wherein the availability and reliability of a piece of equipment during a time period is determined by the processor only if all operating status data collected during the time period has been characterized.

15. The method of claim 13, wherein the availability of the equipment is determined for a time period by subtracting planned downtime and unplanned downtime from the total amount of time in the time period and dividing by the total amount of time in the time period.

16. The method of claim 13, wherein the reliability of the equipment is determined for a time period by subtracting unplanned downtime from the total amount of time in the time period and dividing by the total amount of time in the time period.

17. The method of claim 11, wherein the characterization categories include two or more different categories of unplanned downtime, each unplanned downtime category corresponding to a different component of a system incorporating the at least one piece of equipment from which operating status data is automatically collected.

18. The method of claim 11, further including:

automatically, initially categorizing any time with missing operating status data as uncharacterized;

displaying, on the GUI, at least some of the uncharacterized time with missing data, to a user authorized to characterize downtime;

receiving input from the authorized user to characterize the time with missing data by selecting from a plurality of characterization categories, each category being indicative of a different operating status; and

displaying the characterized time with missing data on the GUI.

19. The method of claim 11, wherein the at least one piece of equipment includes is a fleet of equipment including pieces of equipment at two or more facilities;

and

wherein a fleet manager responsible for managing operation of the fleet of equipment is the only entity with authorization to characterize the operating status data of the fleet.

20. The method of claim 11, further including displaying and receiving information regarding characterized and uncharacterized operating status data via a web-based interface.
