Abstract

This positioning configuration design device includes a positioning configuration setting unit that excludes facilities which are likely to be able to be excluded from facilities respectively positioned at a plurality of locations and sets a positioning configuration of the facilities; a feasibility confirmation unit that judges whether predetermined conditions are feasible or not in the set positioning configuration of the facilities; an exclusion candidate list updating unit that registers, in an exclusion candidate list, information of the facilities excluded in the positioning configuration in which the conditions are feasible, a non-excludable list updating unit that registers, in a non-excludable list, information of the facilities excluded in the positioning configuration in which the conditions are not feasible; and a control unit that repeatedly executes confirmation processing including setting of the positioning configuration and judgment of feasibility of the conditions while incrementing the number of facilities to be excluded one at a time until a positioning configuration in which the conditions are feasible and no further facilities are able to be excluded is able to be calculated.

First claim

1 - 6 . (canceled)

7 . A positioning configuration design device for calculating a smallest positioning configuration for positioning a plurality of facilities,
wherein the positioning configuration design device comprises a control unit that repeatedly executes confirmation processing including processing of setting the positioning configuration while excluding the facilities, in which predetermined conditions are not feasible when the facilities are excluded, from a exclusion target and processing of judging whether the conditions are feasible or not in the set positioning configuration while incrementing the number of the facilities to be excluded one at a time until the positioning configuration in which the conditions are feasible in the positioning configuration of the facilities and no further facilities are able to be excluded is able to be calculated.

8 . The positioning configuration design device according to claim 7 ,
wherein the control unit executes the confirmation processing on the basis of exclusion candidate list data in which information of the excludable facilities allowing the conditions to be feasible even when the facilities are excluded is registered and non-excludable list data in which information of the non-excludable facilities not allowing the conditions to be feasible when the facilities are excluded is registered.

9 . The positioning configuration design device according to claim 8 further comprising:
a storage unit that stores the exclusion candidate list data and the non-excludable list data;
a exclusion candidate list updating unit that registers, in the exclusion candidate list data, information of the facilities excluded in the positioning configuration in which the conditions are feasible; and
a non-excludable list updating unit that registers, in the non-excludable list data, information of the facilities excluded in the positioning configuration in which the conditions are not feasible.

10 . The positioning configuration design device according to claim 9 ,
wherein in the first confirmation processing,
the control unit sets the plurality of combinations of the positioning configurations by excluding the facilities one at a time from the plurality of facilities and judges whether the conditions are feasible or not for each of the plurality of combinations of the positioning configurations,
the exclusion candidate list updating unit registers, in the exclusion candidate list data, the facilities excluded in the positioning configuration in which the conditions are feasible, and
the non-excludable list updating unit registers, in the non-excludable list data, the facilities excluded in the positioning configuration in which the conditions are not feasible.

11 . The positioning configuration design device according to claim 9 ,
wherein in the nth (n is an integer larger than 1) confirmation processing,
the exclusion candidate list updating unit registers, in the exclusion candidate list data, combinations in which the conditions are feasible of combinations of the n facilities to be excluded, and
the non-excludable list updating unit registers, in the non-excludable list data, combinations in which the conditions are not feasible of the combinations of the n facilities to be excluded.

12 . The positioning configuration design device according to claim 9 ,
wherein in the n+1th confirmation processing,
the control unit sets as many combinations of the n+1 facilities to be excluded as possible from the combinations of the n facilities registered in the exclusion candidate list data such that the facilities and combinations of the facilities registered in the non-excludable list data are not included therein.

13 . The positioning configuration design device according to claim 8 ,
wherein the control unit ends execution of the confirmation processing when the combinations of the n facilities are not able to be created any longer such that combinations of the facilities registered in the non-excludable list data are not included therein in the nth confirmation processing.

14 . The positioning configuration design device according to claim 7 ,
wherein the control unit sets an auxiliary feeder line in the vicinity of a location where a value of a voltage becomes the smallest in a power network when the positioning configuration of power facilities supplying power to trains has been calculated.

15 . The positioning configuration design device according to claim 7 ,
wherein the control unit sets an up-down connection resistance connecting an up-line in which a voltage drop in the power network is equal to or greater than a threshold and a down-line in which a voltage drop therein is smaller than the threshold when the positioning configuration of power facilities supplying power to trains has been calculated.

16 . A positioning configuration design method for calculating a smallest positioning configuration for positioning a plurality of facilities,
wherein in the positioning configuration design method, confirmation processing including a step of setting the positioning configuration while excluding the facilities, in which predetermined conditions are not feasible when the facilities are excluded, from a exclusion target and a step of judging whether the conditions are feasible or not in the set positioning configuration is repeatedly executed while incrementing the number of the facilities to be excluded one at a time until the positioning configuration in which the conditions are feasible in the positioning configuration of the facilities and no further facilities are able to be excluded is able to be calculated.

17 . A non-transitory computer-readable medium storing a program for calculating a smallest positioning configuration for positioning a plurality of facilities,
wherein the program causes a computer to repeatedly execute
confirmation processing including a step of setting the positioning configuration while excluding the facilities, in which predetermined conditions are not feasible when the facilities are excluded, from a exclusion target and a step of judging whether the conditions are feasible or not in the set positioning configuration while incrementing the number of the facilities to be excluded one at a time until the positioning configuration in which the conditions are feasible in the positioning configuration of the facilities and no further facilities are able to be excluded is able to be calculated.
