Abstract

A maintenance procedure generation apparatus has an information model management unit that manages an information model including detailed information on maintenance work of a maintenance target, a maintenance target acquisition unit that acquires a maintenance target on which maintenance work is to be actually performed from candidates of the maintenance target, a procedure generation unit that generates a first procedure of maintenance work with respect to the maintenance target acquired by the maintenance target acquisition unit based on the information model managed by the information model management unit, and dynamically corrects a second procedure of maintenance work that needs to be performed in the future by a site worker based on maintenance work selected by the site worker, and a work monitoring control unit that acquires information on maintenance work actually performed by the site worker.

First claim

1 . A maintenance procedure generation apparatus comprising:
an information model management unit that manages an information model including detailed information on maintenance work of a maintenance target; a maintenance target acquisition unit that acquires a maintenance target on which maintenance work is to be actually performed from candidates of the maintenance target; a procedure generation unit that generates a first procedure of maintenance work with respect to the maintenance target acquired by the maintenance target acquisition unit based on the information model managed by the information model management unit, and dynamically corrects a second procedure of maintenance work that needs to be performed in the future by a site worker based on maintenance work selected by the site worker; and a work monitoring control unit that acquires information on maintenance work actually performed by the site worker based on the procedure generated by the procedure generation unit.

2 . The maintenance procedure generation apparatus according to claim 1 , wherein
the work monitoring control unit notifies the procedure generation unit of work selected by the site worker when the site worker selects the maintenance work of a procedure different from the procedure generated by the procedure generation unit, and the procedure generation unit dynamically correct the procedure generated once such that the maintenance work of the maintenance target acquired by the maintenance target acquisition unit is performed while prioritizing the maintenance work selected by the site worker.

3 . The maintenance procedure generation apparatus according to claim 1 , further comprising
a first user interface unit that allows a work editor to input information on a maintenance target, wherein the maintenance target acquisition unit acquires the maintenance target on which maintenance work is to be actually performed based on the information input by the work editor via the first user interface unit.

4 . The maintenance procedure generation apparatus according to claim 1 , further comprising
a second user interface unit that presents the second procedure of maintenance work dynamically corrected by the procedure generation unit to the site worker.

5 . The maintenance procedure generation apparatus according to claim 4 , wherein
the second user interface unit presents, to the site worker, at least one of detailed information on the maintenance work selected by the site worker and the second procedure of maintenance work that needs to be executed after the maintenance work selected by the site worker.

6 . The maintenance procedure generation apparatus according to claim 1 , wherein
the information model managed by the information model management unit includes a first information model systematically representing a class and a property of a maintenance target, a second information model systematically representing the maintenance work, and a third information model systematically representing the first procedure of maintenance work, and the first, second and third information models are associated with each other.

7 . The maintenance procedure generation apparatus according to claim 1 , further comprising
an instance management unit that manages an instance representing a substance of the detailed information included in the information model, wherein the procedure generation unit generates the first procedure of maintenance work with respect to the maintenance target acquired by the maintenance target acquisition unit based on the information model managed by the information model management unit and the instance managed by the instance management unit.

8 . The maintenance procedure generation apparatus according to claim 7 , wherein
the procedure generation unit generates the first procedure of maintenance work with respect to the maintenance target acquired by the maintenance target acquisition unit based on at least one of history information on the first procedure of maintenance work generated in the past and history information on the second procedure of maintenance work performed by the site worker in the past in addition to the information model managed by the information model management unit and the instance managed by the instance management unit.

9 . The maintenance procedure generation apparatus according to claim 1 , wherein
the work monitoring control unit records information on maintenance work performed by the site worker in the past, and the procedure generation unit dynamically corrects the second procedure of maintenance work that needs to be performed by the site worker in the future based on the maintenance work actually performed by the site worker and the procedure generated by the procedure generation unit.

10 . A maintenance procedure generation method comprising:
managing an information model including detailed information on maintenance work of a maintenance target; acquiring a maintenance target on which maintenance work is to be actually performed from candidates of the maintenance target; generating a first procedure of maintenance work with respect to the acquired maintenance target based on the information model, and dynamically correcting a second procedure of maintenance work that needs to be performed in the future by a site worker based on the maintenance work selected by the site worker; and acquiring information on maintenance work actually performed by the site worker based on the generated procedure.

11 . The maintenance procedure generation method according to claim 10 , wherein
the acquiring information on maintenance work notifies work selected by the site worker when the site worker selects the maintenance work of a procedure different from the generated procedure, and the generating the second procedure dynamically corrects the procedure generated once such that the maintenance work of the acquired maintenance target is performed while prioritizing the maintenance work selected by the site worker.

12 . The maintenance procedure generation method according to claim 10 , further comprising
allowing a work editor to input information on a maintenance target, wherein the acquiring the maintenance target acquires the maintenance target on which maintenance work is to be actually performed based on the information input by the work editor.

13 . The maintenance procedure generation method according to claim 10 , further comprising
presenting the second procedure of maintenance work dynamically corrected to the site worker.

14 . The maintenance procedure generation method according to claim 13 , wherein
the presenting the procedure presents, to the site worker, at least one of detailed information on the maintenance work selected by the site worker and the second procedure of maintenance work that needs to be executed after the maintenance work selected by the site worker.

15 . The maintenance procedure generation method according to claim 10 , wherein
the managed information model includes a first information model systematically representing a class and a property of a maintenance target, a second information model systematically representing the maintenance work, and a third information model systematically representing the first procedure of maintenance work, and the first, second and third information models are associated with each other.

16 . The maintenance procedure generation method according to claim 10 , further comprising
managing an instance representing a substance of the detailed information included in the information m
