Maintenance support system and maintenance support method

1. A maintenance support system, comprising:

a network interface;

a memory; and

a processor configured to:

upon receipt of first information indicating a status of a first apparatus among a plurality of apparatuses via the network interface, store the first information in the memory,

upon receipt of second information indicating a status of a second apparatus among the plurality of apparatuses via the network interface, store the second information in the memory, and

determine a priority of on-site maintenance between the first and second apparatuses based on the first and second information stored in the memory, wherein

the processor is further configured to:

calculate a maintenance score for each of the first and second apparatuses,

compare an average score of maintenance scores calculated for all of the plurality of apparatuses with the calculated maintenance score, and

modify the priority based on a comparison result of the average score and the calculated maintenance score.

2. The maintenance support system according to claim 1 , wherein the first and second information indicate one or more errors that have occurred in the first and second apparatuses, respectively.

3. The maintenance support system according to claim 2 , wherein the processor is further configured to:

acquire a first number of errors that have occurred in the first apparatus in a particular period from the first information,

acquire a second number of errors that have occurred in the second apparatus in the particular period from the second information, and

determine the priority based on the first and second numbers of errors such that a higher priority is given to the one of the first and second apparatuses in which more errors have occurred in the particular period.

4. The maintenance support system according to claim 1 , wherein

the memory stores third information indicating a period when each of the first and second apparatuses is most frequently used, and

the priority is determined further based on the third information such that a higher priority is given to one of the first and second apparatuses in which a current date is closer to the period.

5. The maintenance support system according to claim 1 , wherein

the first and second information indicate first and second numbers of devices connected to the first and second apparatuses, respectively, and

the processor is further configured to:

calculate first and second increase rates of devices connected to the first and second apparatuses using the first and second numbers of devices, respectively, and

determine the priority using the calculated first and second increase rates of devices.

6. The maintenance support system according to claim 1 , wherein

the memory stores, for each of the first and second apparatuses, fourth information indicating at least one of: a non-OEM consumable part is being used, a lot number of an attached part, a total number of parts to be replaced, a date of last maintenance, a possibility of a request for future maintenance, and an expiration date of maintenance service, and

the priority is determined further based on the fourth information.

7. The maintenance support system according to claim 1 , wherein the priority is lowered when the calculated maintenance score is higher than the average score, and is increased when the calculated maintenance score is lower than the average score.

8. The maintenance support system according to claim 1 , wherein the first and second information are log information generated by the first and second apparatuses, respectively.

9. The maintenance support system according to claim 1 , wherein the first and second apparatuses are image processing apparatuses.

10. The maintenance support system according to claim 1 , wherein the maintenance score is calculated based on a total number of maintenances performed on each of the first and second apparatuses.

11. A maintenance support method, comprising:

upon receipt of first information indicating a status of a first apparatus among a plurality of apparatuses, storing the first information in a memory,

upon receipt of second information indicating a status of a second apparatus among the plurality of apparatuses, storing the second information in the memory,

determining a priority of on-site maintenance between the first and second apparatuses based on the first and second information stored in the memory,

calculating a maintenance score for each of the first and second apparatuses,

comparing an average score of maintenance scores calculated for all of the plurality of apparatuses with the calculated maintenance score, and

modifying the priority based on a comparison result of the average score and the calculated maintenance score.

12. The method according to claim 11 , wherein the first and second information indicate one or more errors that have occurred in the first and second apparatuses, respectively.

13. The method according to claim 12 , further comprising:

acquiring a first number of errors that have occurred in the first apparatus in a particular period from the first information;

acquiring a second number of errors that have occurred in the second apparatus in the particular period from the second information; and

determining the priority based on the first and second numbers of errors such that a higher priority is given to one of the first and second apparatuses in which more errors have occurred in the particular period.

14. The method according to claim 11 , further comprising:

storing third information indicating a period when each of the first and second apparatuses is most frequently used, wherein

the priority is determined further based on the third information such that a higher priority is given to one of the first and second apparatuses in which a current date is closer to the period.

15. The method according to claim 11 , wherein

the first and second information indicate first and second numbers of devices connected to the first and second apparatuses, respectively, and

the method further comprises:

calculating first and second increase rates of devices connected to the first and second apparatuses using the first and second numbers of devices, respectively, and

determining the priority using the calculated first and second increase rates of devices.

16. The method according to claim 11 , further comprising:

storing, for each of the first and second apparatuses, fourth information indicating at least one of: a non-OEM consumable part is being used, a lot number of an attached part, a total number of parts to be replaced, a date of last maintenance, a possibility of a request for future maintenance, and an expiration date of maintenance service, wherein

the priority is determined further based on the fourth information.

17. The method according to claim 11 , wherein the priority is lowered when the calculated maintenance score is higher than the average score, and the priority is increased when the calculated maintenance score is lower than the average score.

18. The method according to claim 11 , wherein the first and second information are log information generated by the first and second apparatuses, respectively.

19. The method according to claim 11 , wherein the first and second apparatuses are image processing apparatuses.

20. The method according to claim 11 , wherein the maintenance score is calculated based on a total number of maintenances performed on each of the first and second apparatuses.
