Abstract

A method, computing system and computer program product provide additional information relating to maintenance actions to address an issue with a structure. For each maintenance action that has corrected an issue, a first group of structures in which the issue has reoccurred and a second group of structures in which the issue has not reoccurred are identified. The method then determines an actual correction duration value for each of the structures in the first and second groups, generates a correction duration estimate for the structures in the first group using the actual correction duration values and uses the correction duration estimate to identify a portion of the structures in the second group. The method also uses the actual correction duration values calculated for the first group and the identified portion of the second group to generate a fix duration estimate representing an overall time estimation for issue reoccurrence.

Claims

1. A method for providing information relating to maintenance actions to address an issue, the method comprising:

for a respective issue, identifying the maintenance actions that have been performed to correct the issue and that have corrected the issue;

for each respective identified maintenance action, identifying a first group of structures wherein the issue has reoccurred and a second group of structures wherein the issue has not reoccurred;

determining an actual correction duration value for each of the identified structures in the first and second groups;

generating a correction duration estimate (X_A) for the structures in the first group using the actual correction duration values;

using the correction duration estimate (X_A) to identify a portion of the structures in the second group;

using the actual correction duration values calculated for the first group and the portion of the second group to generate a fix duration estimate (FDE) representing an overall time estimation for reoccurrence of the issue; and

causing the FDE to be presented in association with the respective maintenance action to the user.

2. The method of claim 1 further comprising:

generating an FDE for each identified maintenance action; and

presenting the FDEs and the associated maintenance actions as a list for each issue being addressed.

3. The method of claim 1 wherein causing the FDE to be presented comprises presenting the FDE in association with a confidence score for the respective maintenance action.

4. The method according to claim 1 wherein the FDE is generated without consideration of the structures that have undergone the respective maintenance action to address the issue that has not since reoccurred and for which an elapsed time since performance of the respective maintenance action is less than the correction duration estimate (X_A).

5. The method according to claim 1 wherein using the correction duration estimate (X_A) to identify the portion of the structures in the second group comprises identifying the portion of the structures in the second group for which time since the maintenance action was performed exceeds the correction duration estimate (X_A), and wherein the actual correction duration value is defined to be the time since the maintenance action was performed for the portion of the structures in the second group.

6. The method according to claim 5 wherein generation of the FDE comprises determining a sum of the actual correction duration values for the first group and the portion of the second group, and dividing the sum by a total number of structures that are included in the first group and the portion of the second group.

7. The method according to claim 1 wherein a system reset comprises a maintenance action.

8. The method according to claim 1 wherein only actions that resolve the issue, at least temporarily, comprise a maintenance action.

9. A computing system for providing information relating to maintenance actions to address an issue, the computing system comprising processing circuitry configured to:

for a respective issue, identify the maintenance actions that have been performed to correct the issue and that have corrected the issue;

for each respective identified maintenance action, identify a first group of structures wherein the issue has reoccurred and a second group of structures wherein the issue has not reoccurred;

determine an actual correction duration value for each of the identified structures in the first and second groups;

generate a correction duration estimate (X_A) for the structures in the first group using the actual correction duration values;

use the correction duration estimate (X_A) to identify a portion of the structures in the second group;

use the actual correction duration values calculated for the first group and the portion of the second group to generate a fix duration estimate (FDE) representing an overall time estimation for reoccurrence of the issue; and

cause the FDE to be presented in association with the respective maintenance action to the user.

10. The computing system of claim 9 wherein the processing circuitry is further configured to:

generate an FDE for each identified maintenance action; and

present the FDEs and the associated maintenance actions as a list for each issue being addressed.

11. The computing system of claim 9 wherein the processing circuitry is configured to cause the FDE to be presented by presenting the FDE in association with a confidence score for the respective maintenance action.

12. The computing system according to claim 9 wherein the FDE is generated without consideration of the structures that have undergone the respective maintenance action to address the issue that has not since reoccurred and for which an elapsed time since performance of the respective maintenance action is less than the correction duration estimate (X_A).

13. The computing system according to claim 9 wherein the processing circuitry is configured to use the correction duration estimate (X_A) to identify the portion of the structures in the second group by identifying the portion of the structures in the second group for which time since the maintenance action was performed exceeds the correction duration estimate (X_A), and wherein the actual correction duration value is defined to be the time since the maintenance action was performed for the portion of the structures in the second group.

14. The computing system according to claim 13 wherein the processing circuitry is configured to generate the FDE by determining a sum of the actual correction duration values for the first group and the portion of the second group, and by dividing the sum by a total number of structures that are included in the first group and the portion of the second group.

15. A computer program product for providing information relating to maintenance actions to address an issue, the computer program product comprising at least one non-transitory computer-readable storage medium having computer-executable program code instructions stored therein, the computer-executable program code instructions comprising program code instructions for:

for a respective issue, identifying the maintenance actions that have been performed to correct the issue and that have corrected the issue;

for each respective identified maintenance action, identifying a first group of structures wherein the issue has reoccurred and a second group of structures wherein the issue has not reoccurred;

determining an actual correction duration value for each of the identified structures in the first and second groups;

generating a correction duration estimate (X_A) for the structures in the first group using the actual correction duration values;

using the correction duration estimate (X_A) to identify a portion of the structures in the second group;

using the actual correction duration values calculated for the first group and the portion of the second group to generate a fix duration estimate (FDE) representing an overall time estimation for reoccurrence of the issue; and

causing the FDE to be presented in association with the respective maintenance action to the user.

16. The computer program product of claim 15 wherein the computer-executable program code instructions further comprise program code instructions for:
