However, the storage device 32 mainly corresponds to the operation record recording means 6.

[Operation list table]
FIG. 3 is a diagram showing an operation list table. The contents of the operation to be scheduled are shown. Input is performed for each operation from the operation information input device 44 shown in FIG. Then, it is recorded on the hard disk 30.

  The operation number 60 is an identification number assigned to each operation to be scheduled. It may be input or automatically numbered together with the input.

  The subject 61 is the name of the operation.

  The operation type 62 is a code for identifying the type of operation.

  The operation end time 63 represents a time limit at which the operation should be completed by that time at the latest. When performing inspection and maintenance of electrical equipment, etc., it is set because the power supply must be stopped before the start of the work. On the other hand, how soon the operation can be finished is determined by the strict adherence degree 66 described later.

  The operation start time period 64 represents a time when the operation can be started. The operation can be started after this time. The subject 61, the operation type 62, the operation end time 63, and the operation start time 64 are input target items.

  The operation time 65 is a time required for the operation. This is not input, but is set based on past operation results. The setting method will be described later.

  The strict adherence degree 66 is the difference between the operation end time and the operation end time for the operation for which the operation end time is determined, and the operation start time and the operation start time for the operation for which the operation start time is determined. This represents the level at which the difference is acceptable. When the strict adherence degree is 1, the allowable time difference is 0, when the strict adherence degree is 2, the allowable time difference is 20 minutes, and when the strict adherence degree is 3, the allowable time difference is 40 minutes. This is shown in an allowable time difference table (FIG. 4) described later. The strict adherence degree 66 is an input target item.

  The allowable time difference 67 represents the time difference allowed by the strict adherence degree 66 as described above. The allowable time difference is automatically determined based on the degree of strict adherence to time, but it may be corrected for each individual operation as necessary thereafter. For this purpose, description of the input screen and the like is omitted.

  The earliest start time 68 represents the time when the operation can be started earliest from the operation end time 63 or the operation start time 64, the operation time 65, and the allowable time difference 67.

  The latest start time 69 represents the time when the operation can be started latest from the operation end time 63 or the operation start time 64, the operation time 65, and the allowable time difference 67.

  The operation level 70 represents the skill required for the operator who performs the operation. Only an operator with a skill of 1 can perform an operation with an operation level of 1. On the other hand, for an operation with an operation level of 2, any operator with a skill of 1 or 2 can perform. In this example, only the operation level and the skill are set to 1 and 2, but the division may be set more finely. Normally, an operator having a higher skill level can perform an operation with a lower required skill level, but the relationship between the operation level and the skill level of the operator who can perform the operation may be determined as appropriate. The operation level 70 is an input target item.

  The prerequisite operation number 71 represents an operation that must be completed before the operation is performed. Here, only one such operation is determined, but a plurality of operations may be determined. The prerequisite operation number 71 is an input target item.

  The electric station display 72 shows the display of electric stations related to operations in order to perform a schedule under the restriction that only one operation can be performed at the same time zone at one electric station. If there are no such restrictions, this display can be omitted. The electric station display 72 is an input target item.

  The operator limitation / identity 73 is a code that specifies whether or not the operation indicated by the operator limitation / operation number 74 should be the same as the operator. When the operator limitation / identity 73 is “same”, the operation indicated by the operator limitation / operation number 74 and the operator must be the same. When the operator limitation / identity 73 is blank and the operator limitation / operation number 74 is described, the operation and the operator are made to be the same as much as possible. Not necessarily. When the operator limitation / operation number 74 is not described, there is no limitation regarding the identity of the operator. The operator limitation / identity 73 and the operator limitation / operation number 74 are input target items.

[Allowable time difference table]
FIG. 4 is a diagram showing an allowable time difference table. A correspondence relationship between the strict adherence degree 80 and the allowable time difference 81 is shown. A flexible schedule can be set by appropriately changing the allowable time difference.

[Operator table]
FIG. 5 is a diagram illustrating an operator table. It holds an operator name 90, an operator number 91, a skill 92, and an assigned site number 93. In this example, it is shown that two operators, operator A and operator B, are operating at the operation site having the assigned site number 10 and that the skills of the respective operators are 1 and 2. Skill 1 represents a highly skilled person, and skill 2 represents a general skill person.

[Operation result table]
FIG. 6 is a diagram showing an operation result table. An operation type 100 representing the type of operation, a start time 101 that is the time when the operation is actually started, an end time 102 that is the time when the operation is actually ended, and an operation time calculated from the difference between the start time 101 and the end time 102 103, the operation date 104 that is the operation date, the operation number 105 on the operation date, the operator number 106 of the operator who performed the operation, and the skill 107 of the operator.

  The operation result table is input when the operation starts and ends. In actual operation, instead of inputting the time each time, the scheduled content is displayed on the display screen of the operation information input device 44, and a predetermined location is clicked when the operation starts and ends. Just be fine. This is because if the start time and end time are known, other information is determined at the time of scheduling. Thereby, the progress of the operation can be known.

  In the operation result table, since records related to past operations are accumulated, statistics of operation time can be obtained for each operation type. In setting the operation time based on the operation result table, an average value, standard deviation, mode value, maximum value, or the like can be used as necessary. If there is no sufficient record in the past, a standard time set in advance may be used.

Scheduling stop operation
FIG. 7 is a diagram illustrating a stop operation allocation table. Operation scheduling includes operations that have a fixed time limit (hereinafter referred to as a stop operation in the sense that the power must be stopped by the start time of a certain work), and the operation start time limit. This operation is divided into predetermined operations (in the sense that power can be restored after a certain work is completed, hereinafter referred to as a restoration operation). And since the operator's identity may be required between the two, the schedule to be selected is finally narrowed down together. FIG. 7 is a table used for scheduling the stop operation.

  First, from the operation list table (FIG. 3), the operation number 60 and the operation level 70 of the operation whose operation end time limit 63 is determined are extracted. Here, since there are two operators, operator A and operator B, and the skills of both are 1 and 2, respectively, the assignment of the eight extracted operations is based on the operation level according to this example. And there are 64 ways in total. Each case is given a name from assignment 1 to assignment 64. These are merely the types of assignment methods to the operators, and those that satisfy the constraints of the operation start time limit and the operation end time limit are narrowed down. Among these, for example, allocation k is narrowed down according to the following procedure.

  FIG. 8 is a diagram showing the operation number assigned to each operator in the assignment k. In the allocation k, the operator A assigns three operations with operation numbers 1, 3, and 6 (hereinafter referred to as operation 1, operation 3, and operation 6, respectively, the same applies to operations with other operation numbers). B is assigned with five operations of operation 2, operation 4, operation 5, operation 7, and operation 8, respectively.

  FIG. 9 is a diagram illustrating a stop operation order table. This is a list of candidates in the order in which the operator A can perform the three operations of operation 1, operation 3, and operation 6. Since operator A performs three operations, a total of six orders can be considered. For these six ways, names are given to the operation orders Ak1 to Ak6.

  FIG. 10 is a diagram illustrating a method for determining the start time of each operation in the operation order Ak1. Since the operator A can perform only one operation at the same time, consider a case where the operation 1, the operation 3, and the operation 6 are performed in this order.

  Since the operation end time limit is determined for these operations, the operation 6 that ends latest is scheduled so as to meet the operation end time. From the operation list table (FIG. 3), it can be seen that the operation end time of the operation 6 is 10:00 and the operation time of the operation 6 is 30 minutes, so that the operation 6 only needs to start at 9:30. In this case, since the operation 6 ends just at the operation end time limit, the allowable time difference 0 of the operation 6 is satisfied.

  Next, consider operation 3. Operation 3 needs to be completed by the earlier of operation 6 start time 9:30 and operation 3 operation end time 9 o'clock, whichever comes first. And since the operation time of the operation 3 is 40 minutes, it turns out that the operation 3 should just start at 8:20. In this case, since the operation 3 ends just at the operation end time limit, the allowable time difference of the operation 3 of 20 minutes is satisfied.

  If the operation start time is determined for the operation 1 in the same manner, the operation 1 start time is 8 o'clock. In this case, the operation end time limit of operation 1 is 8:40, and the operation end time is 8:20, so the difference is 20 minutes. On the other hand, since the allowable time difference of operation 1 is 40 minutes, the specification of the strict adherence degree is satisfied.

  From the above, if operation 1, operation 3, and operation 6 start at 8 o'clock, 8 o'clock 20 o'clock, and 9:30 o'clock, respectively, all are within the allowable time difference range, and the strict adherence level is designated. It will be satisfied.

  FIG. 11 is a diagram illustrating an evaluation table for each operation order. FIG. 11A shows the operation start time determined by the method described above and the time of each operation when the operator A performs the operation in the order of operation 1, operation 3, and operation 6 (operation order Ak1). This indicates whether or not the strict adherence is possible. FIG. 11B shows the operation start time determined by the same method and the strict adherence time of each operation when the operator A performs the operation in the order of operation 3, operation 1, and operation 6 (operation order Ak3). It is shown whether or not. According to this, since the operation 3 cannot satisfy the allowable time difference, the operation order Ak3 cannot be adopted. Here, the total operation time 108 is the difference between the time at which one of the operations was initially started and the time at which all the operations were completed. The total time difference 109 was the difference between the end times of each operation (the operation end time and the operation end time limit). Difference).

  FIG. 12 is a diagram illustrating an operation order narrowing table related to the assignment k of the operator A. Whether or not the operation order Ak2 and Ak4 to Ak6 can be determined by the same method can be determined as shown in FIG. That is, it can be understood that only the operation order Ak1 can be scheduled to satisfy the condition of the allowable time difference of each operation in the allocation k (when the operator A performs the operations 1, 3, and 6). At this time, for those satisfying the conditions, the total operation time and the total time difference are set.

  Hereinafter, it is possible to check whether or not the operator B can perform scheduling that satisfies the condition of the allowable time difference by the same method. For example, regarding the assignment k, if the operator B can perform the assigned operation by satisfying the conditions in the two operation orders Bki and Bkj, the operator B is combined with the operation order Ak1 related to the operator A. Thus, two schedules, Ak1 + Bki and Ak1 + Bkj, can be created. For each, the total of the operation time for operator A and the total operation time for operator B is the total operation time of the schedule, the total time difference for operator A, and the total time difference for operator B Is the sum of the time differences in the schedule.

  Thereafter, the same method can be used for allocation 1 to allocation 64 to extract a schedule that satisfies the conditions for the allowable time difference.

  FIG. 13 is a diagram illustrating a stop operation schedule narrowing table. It shows that S schedules were extracted in all. Then, for each operation, based on the electric station display, those that satisfy the condition that two or more operations are not performed at the same electric station in the same time zone are narrowed down. In this example, schedule 1 indicates that the condition cannot be satisfied.

[Scheduling recovery operations]
Next, the recovery operation will be described.

  FIG. 14 is a diagram illustrating a recovery operation allocation table. The operations are extracted from the operation list table (FIG. 3) for operations for which the operation start time limit is determined. This corresponds to the stop operation assignment table (FIG. 7). In this example, seven operations are extracted, and a total of 32 assignments are possible considering the operation level. Hereinafter, the allocation m will be described.

  FIG. 15 is a diagram showing an operation number assigned to each operator in assignment m. In the assignment m, the operator A is assigned three operations of operation 10, operation 13, and operation 15, and the operator B is assigned four operations of operation 9, operation 11, operation 12, and operation 14.

  FIG. 16 is a diagram illustrating a recovery operation order table. This is a list of candidates for the order in which the operator A can perform the three operations of the operation 10, the operation 13, and the operation 15. Since operator A performs three operations, a total of six orders can be considered. For these six ways, names are given to the operation orders Am1 to Am6.

  FIG. 17 is a diagram illustrating a method of determining the start time of each operation for each operation order. First, consider the case where operation 10, operation 13, and operation 15 are performed in this order (operation order Am1). FIG. 17A shows the operation order Am1.

  Since the operation start time limit is determined for these operations, the operation 10 that starts first is scheduled to meet the operation start time limit. From the operation list table (FIG. 3), it can be seen that the operation start time limit 64 of the operation 10 is 17:00 and the operation time 65 of the operation 10 is 40 minutes, so that the operation 10 ends at 17:40. In this case, since the operation 10 starts just at the operation start time period 64, the difference between the operation start time and the operation start time period is 0, and the allowable time difference of 20 minutes is satisfied.

  Next, the operation 13 will be examined. The operation 13 can be started from the later of the end time 17:40 of the operation 10 and the operation start time 16:00 of the operation 13. On the other hand, the allowable time difference of the operation 13 is 0, and the operation must be started at the operation start time limit. That is, the operation 13 cannot satisfy the allowable time difference condition. Therefore, the operation order Am1 cannot be adopted.

  When other operation orders are also examined, none of the operation orders Am2 to Am5 can satisfy the condition for the allowable time difference. With respect to the operation order Am6, as shown in FIG. 17B, since all operations can be started at the operation start time limit, the permissible time difference is 0, and it is understood that the condition is satisfied.

  FIG. 18 is a diagram illustrating an evaluation table for each operation order. FIG. 18A shows the operation start time determined by the method described above and the time of each operation when the operator A performs the operation in the order of the operation 10, the operation 13, and the operation 15 (operation order Am1). This indicates whether or not the strict adherence is possible. FIG. 18B shows the operation start time determined by the same method and the strict adherence time of each operation when the operator A performs the operation in the order of operation 15, operation 13, and operation 10 (operation order Am6). It is shown whether or not.

  FIG. 19 is a diagram showing an operation order narrowing table related to the assignment m of the operator A. For those that satisfy the conditions, the time from the start of the first operation to the end of the last operation is taken as the total operation time, and the difference between the operation start time of each operation and the scheduled operation start time Is set as the total time difference.

  Since the operator B can perform the same method, when all of the allocations 1 to 32 are performed, a schedule that satisfies the allowable time difference can be extracted.

  FIG. 20 is a diagram showing a recovery operation schedule narrowing table. This shows that a total of T schedules have been extracted. The narrowing down based on the electric station display is the same as that in the case of the stop operation, and thus the description thereof is omitted.

[Consistency of stop operation and recovery operation]
After scheduling each of the stop operation and the recovery operation, the consistency when these are viewed as a whole is checked. Items to be checked include a check when the operator performing the recovery operation and the operator performing the stop operation must be the same, and other specific operations must be completed as a premise for performing a certain operation There is a check in the case.

[Operator identity determination table]
FIG. 21 is a diagram illustrating an operator identity determination table. As a premise of this figure, regarding the stop operation, in the stop operation schedule narrowing table (FIG. 13), it is assumed that n schedules of schedules t1 to tn are narrowed to satisfy the allowable time difference, and for the recovery operation, It is assumed that m schedules f1 to fm are narrowed down.

  The schedules t1 to tn are scheduled for the operations 1 to 8, and the schedules f1 to fm are scheduled for the operations 9 to 15. Since both are schedules for different operations, there can be n × m combinations of the schedules combining the two.

  Therefore, these are entered in the operator identity determination table (FIG. 21), and the operator identity is determined for the operation for which the operator identity is required. According to FIG. 21, the recovery operation of operation 10 must be the same as the stop operation of operation 3, and the recovery operation of operation 13 must be the same as the stop operation of operation 6 and the operator. And those that do not satisfy these conditions are dropped. In the example of FIG. 21, the combination of schedule t1 and schedule f1, and the combination of schedule tn and schedule fm are missing.

[Operation order judgment table]
FIG. 22 is a diagram illustrating an operation order determination table. This is to determine whether or not the specification of the operation order is satisfied in the n × m overall schedules in which the n schedules of the schedules t1 to tn and the m schedules of the schedules f1 to fm are combined. It is.

  For n × m schedules, the start time and end time of each operation are entered in FIG. In the example of FIG. 22, the operation 5 is premised on the operation 7, so the start time of the operation 5 must be later than the end time of the operation 7. Therefore, both schedules are compared for each schedule. And those that do not satisfy these conditions are dropped. In the example of FIG. 22, the combination of the schedule tn and the schedule fm is missing.

[Post-combination restriction condition judgment result table]
FIG. 23 is a diagram illustrating a post-combination restriction condition determination result table. After the above two determinations are made, the combinations that pass both the determinations are arranged. According to the example of FIG. 23, three combinations of the combination of the schedule t1 and the schedule f2, the combination of the schedule t2 and the schedule fm, and the combination of the schedule tn and the schedule f1 have finally passed the above two determinations. .

[Optimum schedule judgment table]
FIG. 24 is a diagram showing an optimal schedule determination table. It is used to select an optimal schedule by evaluating a schedule that remains without being dropped through the above process.

  For schedules marked with a circle in the post-combination limiting condition determination result table (FIG. 23), total operation time 112 related to stop operation, total time difference 113 related to stop operation, total operation time 114 related to recovery operation, related to recovery operation The total time difference 115, the operation elapsed time 118, the operation time 119 of the operator A, and the operation time 120 of the operator B are entered.

  The total operation time 112 related to the stop operation is an elapsed time from the start time of the first stop operation to the end time of the last stop operation. The operator is not asked.

  The total time difference 113 related to the stop operation is the sum of the differences between the operation end time and the operation end time of each stop operation. The time to start the operation can be obtained by subtracting the operation time from the operation end time of each stop operation, and the time to start the operation (the time scheduled as the start time) by subtracting the operation time from the operation end time. Therefore, the time difference sum 113 can also be interpreted as the sum of the differences between the time period (start reference time) at which each stop operation should be started and the time at which each stop operation should be started.

  The total operation time 114 related to the recovery operation is an elapsed time from the start time of the first recovery operation to the end time of the last recovery operation. The operator is not asked.

  The total time difference 115 related to the recovery operation is the total difference between the operation start time and the operation start time of each recovery operation.

  The operation elapsed time 118 is an elapsed time from the start time of the first stop operation to the end time of the last recovery operation.

  The operation time 119 of the operator A includes the elapsed time from the start time of the first stop operation related to the operator A to the end time of the last stop operation and the last time from the start time of the first recovery operation related to the operator A. This is the total of the elapsed time up to the end time of the recovery operation. The same applies to the operation time 120 of the operator B.

  The total time difference 116 related to the entire operation is the sum of the total time difference 113 related to the stop operation and the total time difference 115 related to the recovery operation, and is automatically calculated.

  The total operation time 117 related to the entire operation is the sum of the total operation time 112 related to the stop operation and the total operation time 114 related to the recovery operation, and is automatically calculated.

  The operation time difference 121 between the operators is a difference between the operation time 119 of the operator A and the operation time 120 of the operator B, and is automatically calculated. When the number of operators is three or more, the difference between the longest operation time and the shortest operation time is assumed.

  Any of these can be easily obtained by using an operator who should perform an operation, an operation start time, and an operation end time for each operation.

  From these numerical values, an optimal schedule can be selected by determining the priority. For example, the following selection rule can be considered.

  First, a schedule (combination of a schedule for a stop operation and a schedule for a recovery operation) with the shortest time difference total 116 for the entire operation is selected. This is because the time difference between the operation start time period and the operation end time period and the operation start time and the operation end time is the smallest overall, for example, there is an effect that the power failure time can be minimized.

  When a plurality of schedules are selected in the first selection, the second one having the smaller total operation time 117 for the entire operation is selected.

  If a plurality of schedules are also selected in the second selection, the third one having the shorter operation elapsed time 118 is selected.

  When a plurality of schedules are selected in the third selection, the fourth one having the smaller operation time difference 121 between operators is selected.

  When a plurality of schedules are selected even in the fourth selection, the operation number of the operation number is determined even though the identity limited to the operator is blank in the operator identity determination table (FIG. 21). For the designated one, the operator who has the same operation number as the operation is selected. This is because the identity of the operator is not a necessary condition but an expected condition as long as the identity is blank.

  Note that these are examples of selection rules, and the selection rules are not limited to this, and the selection rules may be set appropriately according to the purpose.

[flowchart]
FIG. 25 is a diagram showing an overall processing flow of the operation schedule creation system.

  S1: The operation information input device 44 inputs an operation to be scheduled. Here, the operation schedule creation system includes operation item input means 2.

  S2: Based on the operation record in the operation record DB recorded on the hard disk 30, an expected operation time is set for the operation input by the operation information input device 44. Here, the operation schedule creation system includes an expected operation time setting unit 3.

  S3: Set schedule parameters. The schedule parameters include an allowable time difference (contents of the allowable time difference table (FIG. 4)) corresponding to the degree of strict adherence, the number of operators and skills (contents of the operator table (FIG. 5)), and the like. If necessary, an allowable time difference may be set for each operation.

  S4: The operator and the operation start time are determined for each operation in consideration of the allowable time difference. Details of each process will be described with reference to a flowchart described later. Here, the operation schedule creation system includes an operation start schedule determination means 4.

  S5: It is determined whether a schedule that satisfies the conditions is possible. This is because, for example, the number of operations is large, and the schedule that satisfies the condition may not be satisfied by the number of operators set initially. If a schedule that satisfies the conditions cannot be established (S5: No), the process returns to S3, the schedule parameters are reset, and the processes from S3 onward are repeated. For resetting the schedule parameter, a preliminary schedule parameter may be prepared in advance, or an input for resetting may be obtained. When a schedule that satisfies the conditions can be made (S5: Yes), the operation proceeds to execution.

  S6: Although the execution of the operation itself is performed by the operator, the start and end of each operation are input in the execution process of the operation. In response to the input, the progress of the operation status and the operation results are recorded in the operation record DB.

  S7: The operation status is displayed. This includes voice guidance for operation time and the like. Here, the operation schedule creation system includes an operation status display means 5.

  S8: When the operation is completed earlier than scheduled or when trouble occurs, it may be necessary to schedule the remaining operations optimally under the circumstances. Therefore, it is checked whether or not there is such a schedule change factor. If there is a change factor (S8: Yes), the process returns to S1 and scheduling is performed again.

  At that time, if there is a new operation added, or if an operation that has not been started is canceled due to an already input operation, it will be performed from the input of the operation item, but if the operation ends earlier than planned, There is no new input, only the remaining operations are rescheduled.

  Note that when canceling an already input operation, it is sufficient to input only the cancellation, but the operation item input means 2 checks whether the operation can be canceled, such as whether the operation has not started yet.

  FIG. 26 is a diagram showing a processing flow of the operation start schedule determination means 4 of the operation schedule creation system.

  S10: The stop operation to be scheduled is assigned to each operator. Specifically, a stop operation allocation table (FIG. 7) is created.

  S11: The operation order performed by the operator is set for the distributed operations. Specifically, a stop operation order table (FIG. 9) is created.

  S12: For each operation order, it is determined whether or not the time condition related to the allowable time difference is appropriate. Specifically, an operation order-specific evaluation table (FIG. 11) is created.

  S13: As a result of determining whether or not the time condition is correct, a schedule that satisfies the condition is extracted. At that time, the condition that two or more operations are not performed at the same electric station in the same time zone is also determined. Specifically, a stop operation schedule narrowing table (FIG. 13) is created.

  S14 to S17: The same processing as described above is performed for the recovery operation.

  S18: The stop operation and the recovery operation are combined to determine whether or not the relevant condition between the operations is correct. Specifically, the operator's identity condition is determined and the processing order condition between operations is determined (FIGS. 21 and 22).

  S19: As a result of the above determination, a condition satisfaction is extracted. Specifically, an optimum schedule determination table (FIG. 24) is created.

  S20: The optimum schedule plan is selected. Specifically, the optimal schedule plan is selected according to the evaluation rule based on the optimal schedule determination table (FIG. 24).

(Second Embodiment)
In the first embodiment, the operation level is set for each operation and the skill required for the operator is specified. However, in the second embodiment, the operation level is not set, and instead, the skill of the operator is set. The operation time is changed accordingly. This is because, depending on the operation, there is an operation that requires a high skill, but even if it is not a high-skilled operator, there is a possibility that such an operation can be performed if time is required.

  Even in this case, if a certain operation can only be left to a highly skilled person, the operation time of the general skill person should be set to infinity (actually a sufficiently long time such as 1000 minutes). Therefore, it is possible to take operations that are substantially limited to highly skilled workers.

  FIG. 27 is a diagram showing an operation list table according to the present embodiment. In this embodiment, the operation list table (FIG. 27) does not have an operation level column, but has a column for setting an operation time according to the skill. And when setting operation time based on an operation performance table (FIG. 6), the operation time according to skill can be set by taking statistics according to skill.

  If there is not enough performance data for one skill, a standard time set in advance may be used, or the other operation time may be proportionally increased or decreased by a predetermined ratio. The operation schedule of the operator is performed using the operation time set in this way. The skill level is not limited to two and may be three or more.

  According to the present embodiment, scheduling that reflects the fact that the operation time generally varies depending on the skill of the operator is possible. As a result, it can be expected that the willingness to improve skills is likely to increase. In addition, when there is a shortage of high-skilled operators, it is possible to schedule when the number of general-skilled operators can be increased.

  As mentioned above, although embodiment of this invention was described, this invention is not restricted to embodiment mentioned above. The effects described in the embodiments of the present invention are only the most preferable effects resulting from the present invention, and the effects of the present invention are limited to those described in the embodiments of the present invention. is not.
