Abstract

A management system for creating an inspection schedule of objects to be tested within a plurality of management areas, includes a calculation unit that calculates the costs for inspecting the objects to be tested based on the positional information; and a schedule creation unit that creates a schedule for inspecting the objects to be tested based on calculation results. The calculation unit calculates a first cost required when the objects to be tested within the management areas are inspected at the same timing within a first time limit, and a second cost required when a part of the objects to be tested within the management areas is inspected within the first time limit, individually, and the other objects to be tested within the management areas are inspected at the same timing within a second time limit longer than the first time limit.

Claims

1. A management system for creating an inspection schedule of objects to be tested within a plurality of sectioned management areas, the management system comprising:

a database that stores an inspection time limit and positional information of the objects to be tested;

a calculation unit that calculates the costs for inspecting the objects to be tested on the basis of the positional information; and

a schedule creation unit that creates a schedule for inspecting the objects to be tested on the basis of calculation results,

wherein the calculation unit calculates a first cost required when the objects to be tested within the management areas are inspected at the same timing within a first time limit, and a second cost required when a part of the objects to be tested within the management areas is inspected within the first time limit, individually, and the other objects to be tested within the management areas are inspected at the same timing within a second time limit longer than the first time limit, and

wherein the schedule creation unit compares the calculated first costs with the calculated second costs, and creates an inspection schedule in which the time limits when the objects to be tested within each of the management areas are inspected are combined with the objects to be tested, individually, on the basis of comparison results.

2. The management system according to claim 1,

wherein the schedule creation unit forms the objects to be tested which are inspected, individually, and the objects to be tested which are inspected individually within the other management area into a group, and

wherein the schedule creation unit creates the inspection schedule that inspects the objects to be tested which are included in the group at the same timing.

3. The management system according to claim 1,

wherein the schedule creation unit creates the combination that minimizes the costs per a unit time.

4. The management system according to claim 1,

wherein the schedule creation unit compares the first costs with the second costs by the costs per a unit time.

5. The management system according to claim 1,

wherein the schedule creation unit compares the first costs with the second costs by calculating a difference between the first costs and the second costs in each of the management areas, and

wherein the schedule creation unit stores the calculated difference of the costs as an evaluation index for determining the combination.

6. The management system according to claim 5,

wherein the schedule creation unit creates an inspection schedule that inspects, individually, a part of the objects to be tested within the management area in which the second costs are lowest in the first costs among the evaluation index held by each of the management areas, and inspects the other objects to be tested within the management area at the same timing in the time limit longer than the given time limit.

7. The management system according to claim 1,

wherein the schedule creation unit acquires digitalized map information, and

wherein the schedule creation unit superimposes the created inspection schedule and the information on the objects to be tested which is included in the inspection schedule on the acquired map information, and displays the superimposed information.

8. The management system according to claim 1, further comprising:

a priority calculation unit that calculates the priority of the test of the objects to be tested on the basis of the information stored in the database, and calculates the time limit of the inspection according to the calculated priority.

9. The management system according to claim 8,

wherein the priority calculation unit calculates the time limit of the inspection on the basis of an influence rate when the objects to be tested fail, failure information caused by an installation environment of the objects to be tested, and history information that the objects to be tested have been tested or failed in past.

10. The management system according to claim 8,

wherein the time limit of the inspection is determined on the basis of the objects to be tested which are highest in the priority within each of the inspection areas.

11. The management system according to claim 8,

wherein each of the management areas is determined on the basis of the costs calculated on the basis of the priorities of the respective objects to be tested and the positional information.

12. A management method for creating an inspection schedule of objects to be tested within a plurality of sectioned management areas, the management method comprising:

a first step of storing an inspection time limit and positional information of the objects to be tested;

a second step of calculating a first cost required when the objects to be tested within the management areas are inspected at the same timing within a first time limit, on the basis of the positional information;

a third step of calculating a second cost required when a part of the objects to be tested within the management area is inspected in the first time limit, individually, and the other objects to be inspected within the management area are inspected within a second time limit longer than the first time limit at the same timing, on the basis of the positional information;

a fourth step of comparing the calculated first cost with the calculated second cost;

a fifth step of determining the combination of the time limit where the objects to be tested within each of the management areas are inspected with the objects to be tested which are inspected, individually, on the basis of a result of the comparison in the fourth step; and

a sixth step of creating the inspection schedule on the basis of the combination determined in the fifth step.

13. The management method according to claim 12,

wherein the fifth step includes

forming the objects to be tested which are inspected, individually, and the objects to be tested which are inspected within the other management areas, individually, into a group, and

creating the inspection schedule for inspecting the objects to be tested, which are included in the group, at the same timing.

14. The management method according to claim 12,

wherein the fifth step includes determining the combination which are lowest in the costs per a unit time.

15. The management method according to claim 12,

wherein the second step includes calculating the first cost per the unit time,

the third step includes calculating the second cost per the unit time, and

the fourth step includes comparing the first cost with the second cost by the cost per the unit time.
