A function for exchanging the two is provided.

Japanese Unexamined Patent Publication No. 2000-071988

  However, in the above conventional technique, the exchangeable range is two operations on an arbitrary date, and there is a problem that the exchange cannot be performed in an arbitrary period of two days or more. In addition, before the exchange, the organization information before and after the exchange at the exchange source and exchange destination (operation details indicating the travel distance of each train, the number of station berths, etc.) cannot be confirmed. Therefore, for example, when there are multiple replacement candidate operations, it is not possible to determine in advance which of the multiple candidates is the best to select as the replacement destination, and the organization information is confirmed by performing a replacement once However, if it is determined that the exchange destination is not the best, it is necessary to perform the exchange again after canceling the operation (after returning to the original state).

  As described above, in the conventional equipment operation plan creation method and system, there is a problem that the operation exchange work in the editing (correction) work of the vehicle operation plan cannot be performed efficiently.

  The present invention has been made in view of the above, and an object of the present invention is to obtain a vehicle operation plan creation device and a vehicle operation plan correction method that realize efficient plan correction in a short time.

  In order to solve the above-described problems and achieve the object, the present invention creates a vehicle operation plan in which trains to be operated are assigned to route information indicating train operation routes and operation times in an arbitrary period. The vehicle operation plan creation device, wherein the vehicle operation plan display unit that displays the vehicle operation plan and allows a user to confirm the vehicle operation plan is designated as an exchange source organization and one of the trains assigned to the vehicle operation plan, In addition, when a predetermined period included in the arbitrary period is designated as a target period, a predetermined constraint condition violation is generated based on the switching source operation plan that is route information assigned to the switching source organization in the target period. And a constraint condition determination processing unit that extracts other trains that can exchange the operation allocation in the target period as replacement destination candidate formations.

  According to the present invention, when the operation (period and organization) as the exchange source is specified, the operation in which no constraint violation occurs even if the replacement is performed is extracted. Can be easily performed, and the work efficiency can be improved and the work load of the user can be reduced.

  Embodiments of a vehicle operation plan creation device and a vehicle operation plan correction method according to the present invention will be described below in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

  First, the vehicle operation plan creation device assumed in each embodiment will be described. The vehicle operation plan creation device is, for example, information on each train that is the target of the operation plan (information including identification information, location, etc.), operation start location of the train (station, vehicle base, etc.), operation start time, Various information necessary to create a vehicle operation plan, such as route information indicating the operation end location and operation end time, and work information related to train inspection and cleaning work, etc. ) (A function for allowing the user to input various information). In addition, when a predetermined operation instructing the start of creation of a vehicle operation plan is performed by the user, a function for automatically or manually creating a vehicle operation plan based on the above-mentioned various information, and the vehicle operation already created Has the function to modify the plan. It may have a function of creating a vehicle operation plan by combining automatic creation and manual creation. For example, a function may be provided in which an operation plan is manually performed for some dates and trains, and the rest is automatically planned. The vehicle operation plan is information that indicates when and on which route each train owned by a railway company (organization composed of one or more vehicles) is used (operated). Also, information on various operations different from normal operations, such as information on the date and time of inspection of each train and information on the location of inspection, information on the date and time of cleaning and information on the location of cleaning, is included.

  Next, an embodiment of a vehicle operation plan creation device having the above function will be described.

Embodiment 1 FIG.
FIG. 1 and FIG. 2 are diagrams illustrating an example of a screen display of the vehicle operation plan creation apparatus according to the first embodiment. In any figure, the example in the case of displaying the produced vehicle operation plan or the vehicle operation plan in the middle of preparation is shown. Moreover, the example at the time of displaying the vehicle operation plan of the same content for the comparison of the display content is shown. The vehicle operation plan creation device starts displaying these screens when a predetermined operation is received from the user. In FIG. 1 and FIG. 2, the same reference numerals are assigned to portions displaying the same information.

  The screen display shown in FIG. 1 includes an automatic creation tab 101 for displaying a result of automatically creating a plan, a manual creation tab 102 for displaying a result manually created by a user, and a route or inspection / work as a restriction condition in advance. It consists of a condition setting tab 103 to be input, and it is possible to create a plan and set constraint conditions automatically or manually. The vehicle operation plan created by selecting the automatically created tab 101 or the manually created tab 102 can be edited (corrected) on these tabs.

  FIG. 1 shows an example of the configuration of the manual creation tab 102 when the manual creation tab 102 is selected, but the configuration of the automatic creation tab 101 is the same as that of the manual creation tab 102. These automatic creation tab 101 and manual creation tab 102 are configured by arranging a vehicle operation plan table 104 on the left side and a vehicle operation order table 109 on the right side. A pull-down menu 115 is arranged on the upper right, and a constraint violation list 116 and an automatic creation button 117 are arranged on the lower side.

  The vehicle operation plan table 104 includes a composition number 105 displayed in the row header, a date 106 displayed in the column header, a route number 107 and work information 108 displayed in each cell specified by the composition number 105 and the date 106, It is composed of organization information 118 arranged at the right end of each row. The organization number 105 is train identification information, and the route number 107 is a management number of route information. The work information 108 is information indicating work such as cleaning and inspection. The formation information 118 is operation detailed information indicating the average mileage per day of each formation (train corresponding to the formation number 105), the total number of station delays in the plan creation period, and the like. The user can carry out manual operation plan creation work and editing work while referring to the composition information 118. In the display format shown in FIG. 1, since the display area of one cell is small, many vehicle operation plan creation results can be seen at a time.

  In the vehicle operation plan table 104, a horizontal scroll bar 120 and a vertical scroll bar 121 are displayed. These scroll bars are configured to be linked between the automatic creation tab 101 and the manual creation tab 102. For example, when the automatic creation tab 101 and the manual creation tab 102 are switched, the same cell as that displayed on the switching source tab is displayed immediately after switching. When the plan creation period is long and the plan creation period cannot be displayed on the screen, the horizontal scroll bar 120 is displayed. At this time, the composition information 118 may be always displayed without scrolling. When the composition information 118 is always displayed, it is easy to check the composition information 118 when the vehicle operation plan is created / edited, and the work can be performed efficiently.

  Further, when a predetermined operation is performed in the editing operation of the vehicle operation plan table 104 by the user, the vehicle operation plan creation device displays an edit context menu 119.

  The vehicle operation order table 109 includes a route number 110, an operation start location 111, an operation start time 112, an operation end location 113, and an operation end time 114, and for each route number 110, the operation start location 111 to the operation end location. The route information up to 113 is shown. The route number 110 corresponds to the route number 107 displayed in each cell of the vehicle operation plan table 104. When the user wants to know the details of the route corresponding to the route number displayed in each cell of the vehicle operation plan table 104, the user can know it by checking the item of the same route number in the vehicle operation sequence table 109. Further, as illustrated, the operation start time 112 and the operation end time 114 are displayed in parentheses on the right side of the operation start location 111 or the operation end location 113. Further, the vehicle operation order table 109 has a vertical scroll bar 122, which is the same as the horizontal scroll bar 120 and the vertical scroll bar 121 of the vehicle operation plan table 104, and the automatic creation tab 101 and manual creation. It is configured to link with the tab 102.

  The pull-down menu 115 is used when the user switches between the screen display of FIG. 1 and the screen display of FIG. The constraint violation list 116 shows that when the vehicle operation plan is manually created or the vehicle operation plan is edited, the departure place of the route number and the entry place on the previous day are inconsistent, or the inspection / work is violated. When this occurs, the violation content is displayed. The automatic creation button 117 is used when the user instructs the start of automatic creation of the vehicle operation plan in a state where the automatic creation tab 101 is selected. There is a problem if the automatic creation button 117 is erroneously operated and the automatic creation is started while the manual creation tab 102 is selected and the vehicle operation plan is being created manually. Therefore, in the manual creation tab 102, the automatic creation button 117 cannot be pressed (automatic creation is not started even when pressed). While the manual creation tab 102 is selected, the automatic creation button 117 may not be displayed.

  In this embodiment, since it is assumed that the condition setting is performed in advance, the detailed configuration of the condition setting tab 103 used in the condition setting operation by the user will not be described.

  On the other hand, the screen display shown in FIG. 2 is obtained by replacing the vehicle operation plan table 104 and the vehicle operation order table 109 of the screen display shown in FIG. 1 with a vehicle operation plan table 104a and a vehicle operation order table 109a. The vehicle operation plan table 104a is configured to further display an operation start time 201, an operation end time 202, a bar diagram 203, an operation start location 204, and an operation end location 205 in each cell of the vehicle operation plan table 104. is there. The vehicle operation order table 109 a is configured to further display the bar diagram 206 in the vehicle operation order table 109. Since this display format includes more information than the cell information of FIG. 1, the user can see the creation results of each organization in detail. Further, a bar diagram 203 indicating a time axis from the operation start time 201 to the operation end time 202 is also included, so that the time during which the train (train) is traveling can be visually understood.

  Next, the operation of the vehicle operation plan creation device will be described. In the present embodiment, an operation for creating a vehicle operation plan (new creation operation) and an operation for editing a created vehicle operation plan (editing operation) will be described.

(New creation operation)
When creating a vehicle operation plan, the user displays the screen of FIG. 1 or 2 and selects the condition setting tab 103 to set conditions. In the condition setting, the period for scheduling and the setting of the organization (that is, the setting of the row header and column header of the vehicle operation plan tables 104 and 104a), the setting of the route information, the setting of the constraint conditions such as the work schedule information, and the like are performed. When the condition setting is completed, the user switches to the automatic creation tab 101 or the manual creation tab 102 and creates a vehicle operation plan.

  When the vehicle operation plan is automatically created, the user presses the automatic creation button 117 on the automatic creation tab 101. Upon receiving this operation, the vehicle operation plan creation device performs an operation plan for the period and composition set using the condition setting tab 103 while considering that no constraint condition violation occurs.

  When the vehicle operation plan is manually created, the user uses the manual creation tab 102 to perform an operation plan for each organization using an input device such as a mouse. For example, one of the route information displayed in the vehicle operation order tables 109 and 109a is selected, and the cell to which the selected route information is assigned (identified by the organization number 105 and the date 106 of the vehicle operation plan tables 104 and 104a). Cell). The route information and the cell to which it is assigned are selected by dragging and dropping the route information. When a constraint violation occurs in the route information and assignment destination cell selection operation, the vehicle operation plan creation device displays a message to that effect on the constraint violation list 116. For example, if you try to assign a route that can be operated only on holidays to a weekday cell, or if you try to assign multiple same routes to a cell on the same date, there will be a discrepancy with the previous day or next day of the selected cell. Such as when the previous day's operation end location does not match the operation start location, or when the operation end location does not match the next day's operation start location, etc. ("This route cannot be assigned on weekdays") , "No more than one same route can be assigned on the same day", "The operation end location of the previous day does not match the operation start location (the operation start location of the next day does not match the operation end location") indicate.

(Editing action)
In the state where the screen display shown in FIG. 1 or FIG. 2 is performed (the vehicle operation plan that has been created or the vehicle operation plan that is being created is displayed) When the operation for exchanging the operation and the operation of another organization is performed, the vehicle operation plan creation device displays a screen (editing operation screen) as shown in FIG. For example, as shown in FIG. 1 or FIG. 2, the user selects 4/1 to 4/3 of organization number H01 with the mouse and, after right-clicking, activates the editing context menu 119, and then performs “exchange”. When selected, the editing work screen of FIG. 3 is displayed.

  FIG. 3 is a diagram illustrating an example of a vehicle operation plan editing work screen, and shows a work screen when exchanging operations for a specified period.

  The editing work screen shown in FIG. 3 includes an exchange source organization 301 and an exchange destination organization candidate list 308. The organization number 302 is displayed in the row header of the exchange source organization 301 and the exchange destination organization candidate list 308, and the date 303 included in the arbitrarily determined period (period selected by the user) is displayed in the column header. In each cell, a route number 304 and work information 305 such as cleaning / inspection are displayed.

  Here, the vehicle operation plan creation device displays information for one replacement source organization on the replacement source organization 301, and displays all the information on the exchangeable organization in the replacement destination organization candidate list 308. Details of the operation for extracting exchangeable composition information will be described later. The user can select one composition to be exchanged from exchangeable composition information (composition information displayed in the exchange destination composition candidate list 308). Further, the vehicle operation plan creation device displays the pre-replacement formation information 306 and the post-replacement formation information 307 at the right end of the replacement source formation 301 and the replacement destination formation candidate list 308. The composition information before replacement 306 is operation detailed information of each composition before the replacement is performed, and the composition information after replacement 307 is operation detailed information of each composition when the replacement is performed (after the execution). The post-exchange composition information 307 of the exchange composition 301 is displayed when the composition to be exchanged is selected (display contents are updated). The post-exchange composition information 307 in the exchange-destination composition candidate list 308 is always displayed because there is only one exchange partner (the composition information displayed in the exchange-source composition 301). As a result, the user can grasp detailed information such as the average mileage per day before and after the replacement and the total number of station berths during the planning period before performing the replacement. can do. FIG. 3 shows an example in which one entire row of the replacement destination organization candidate list 308 is selected. However, a screen configuration in which a check button or the like is provided and a check is made there may be adopted. The setting button 309 is a button for the user to instruct the start of the operation for exchanging the displayed operation of the exchange organization and the operation of the selected exchange organization, and the cancel button 310 cancels the operation exchange function. It is a button for instructing. When the cancel button 310 is pressed, the display of the editing work screen shown in FIG. 3 is terminated, and the previous screen display (screen display shown in FIG. 1 or FIG. 2) is returned.

  As shown in FIGS. 1 and 2, the user activates the editing context menu 119 by right-clicking in a state where an arbitrary period is selected, and then performs “cut”, “copy”, and “paste”. Alternatively, by selecting “Clear”, an editing operation corresponding to the selected content can be performed. Operations that can be selected in the editing context menu 119 are not limited to those shown in the figure. Other operations may be selected.

  Next, the configuration of the vehicle operation plan creation device will be described. FIG. 4 is a block diagram illustrating a configuration example of the vehicle operation plan creation device. As shown in the figure, the vehicle operation plan creation device includes a route information database 401, a route information selection unit 402, a date information database 403, a work schedule information database 404, a constraint condition determination processing unit 405, a plan information database 406, and a vehicle operation plan. A display unit 407 is provided.

  In the route information database 401, route information is registered. The route information selection unit 402 reads necessary route information from the route information database 401 in the operation of creating or correcting the vehicle operation plan, and displays the vehicle operation order table 109 based on the read route information. Further, when one of the routes displayed in the vehicle operation order table 109 is selected by the user, the selection result is notified to the constraint condition determination processing unit 405. In the date information database 403, date information for determining whether or not a route that can be operated only on weekdays is not input on a holiday or whether or not a route that can be operated only on holidays is input on a weekday is registered. . In the work schedule information database 404, work schedule information such as train inspection and cleaning is registered.

  The constraint condition determination processing unit 405 determines whether or not the user's operation falls under a constraint condition violation in the operation of creating or correcting the vehicle operation plan. Specifically, when the user selects a route in the vehicle operation order table 109 and performs an operation of assigning it to a cell in the vehicle operation plan table 104, it is determined whether or not the route can be assigned to the corresponding cell. That is, the date information database 403 is referred to and it is determined whether or not a route that can be operated only on weekdays is not assigned to a holiday. Further, the route information database 401 is referred to, and it is determined whether or not the departure place (operation start location) of the route to be allocated matches the entry location (operation end location) of the previous day. In addition, referring to the work schedule information database 404, it is determined whether or not the vehicle can be cleaned or inspected in the composition for inputting a route (whether or not a constraint condition violation for cleaning or inspection occurs).

  In the plan information database 406, plan information to be displayed as the vehicle operation plan table 104 (see FIGS. 1 and 2) is registered. This plan information is updated based on the route information or the like as a determination target when the constraint condition determination processing unit 405 performs the above determination process and is not determined to be a constraint condition violation.

  The vehicle operation plan display unit 407 displays the vehicle operation plan table 104 on the screen based on the plan information registered in the plan information database 406. When the plan information registered in the plan information database 406 is updated, the vehicle operation plan display unit 407 is notified to that effect, and the vehicle operation plan display unit 407 is based on the updated plan information. Update the display of.

  In addition, in the vehicle operation plan creation apparatus according to the present embodiment, in addition to the above-described operation, the constraint condition determination processing unit 405 further replaces the operation of a certain composition and the operation of another composition in an arbitrary period. If the exchange source organization is selected for this purpose, the replacement candidate organization (exchangeable organization) is extracted. That is, other knitting in which no constraint condition violation occurs even if the knitting of the exchange source and the exchange are executed is extracted. Details of this operation will be described separately.

  Next, a drawing of the characteristic operation of the vehicle operation plan creation device, specifically, the operation when the user performs an operation for exchanging the operation of the organization for an arbitrary period and the operation of another organization is shown in the drawings. The description will be given with reference.

  FIG. 5 is a flowchart showing an operation example of the vehicle operation plan creation device, and more specifically shows an operation example in a case where the operation of a certain composition is exchanged with the operation of another composition.

  When exchanging the operation of a certain composition and the operation of another composition, first, the user selects the composition and period of the exchange source on the screen of the manual creation tab shown in FIG. 1 or FIG. 2 (step S501). Then, after the editing context menu 119 is activated, “exchange” is selected (step S502). As a result, the editing work screen shown in FIG. 3 is activated, and on this editing work screen, the replacement source organization 301 and the replacement destination organization candidate list 308 that are the selection results in step S501 are displayed. When there is no exchangeable composition, the exchange destination composition candidate list 308 is blank. In this state, the user checks whether there is a composition to be exchanged among the compositions displayed in the exchange composition candidate list 308 (step S503). If there is a knitting to be exchanged (step S503: Yes), the knitting to be exchanged is selected and the setting button is pressed (step S504). When the setting button is pressed, the vehicle operation plan creation device returns to the screen display of the manual creation tab of FIG. 1 or FIG. 2, and the route / work information in the replacement organization / period and the route in the selected organization / period. Exchange work information (step S505). If there is no knitting to be exchanged in the knitting displayed in the replacement knitting candidate list 308 (step S503: No), the user presses the cancel button, and as a result, the vehicle operation plan is created. The device returns to the screen display of the manual creation tab of FIG. In this case, steps S504 and S505 are not executed.

  Here, a display method of the replacement source organization 301 and the replacement destination organization candidate list 308 on the editing work screen shown in FIG. 3 will be described. FIG. 6 is a flowchart showing an example of the flow of display processing when the vehicle operation plan creation device displays the replacement source organization 301 and the replacement destination organization candidate list 308.

  In the vehicle operation plan creation device, first, operation / work information (composition number 302, date 303, route number 304, work information 305) in the composition / period of the exchange source is displayed in the exchange source composition list (step S601). Next, a variable i indicating the organization name is defined, and the value of the variable i is set to 1 (step S602).

  Next, it is confirmed whether or not the organization of the variable i is the organization of the exchange source (step S603) and whether or not the organization of the variable i is an exchangeable organization (step S604). When the composition is not the exchange composition (step S603: No), and the composition is exchangeable (step S604: Yes), the operation / work information in the composition / period of the variable i (composition number 302, date 303, The route number 304 and the work information 305) are displayed on the replacement organization candidate list 308 (additional display when other operation / work information is displayed) (step S605). Then, the variable i is incremented (step S606). On the other hand, when the organization of the variable i is the organization of the exchange source (step S603: Yes), and when the organization of the variable i is not exchangeable (step S604: No), step S606 is not executed and step S606 is performed. Run.

  After executing step S606, it is checked whether or not “variable i ≦ total number of knitting” is satisfied (whether the value of variable i exceeds the total number of knitting) (step S607), and if satisfied (step S607: Yes). The processes in steps S603 to S606 are executed again. On the other hand, when the above condition is not satisfied (step S607: No), the process is terminated. That is, it is determined whether or not the knitting is exchangeable and the screen display is updated according to the determination result (the processing shown in steps S603 to S605) for all the knitting.

  Here, a method for determining whether or not the knitting can be exchanged in step S604 will be described. FIG. 7 is a flowchart illustrating an example of a procedure for determining whether or not two trains can be exchanged.

  When the process is executed in step S604, in the vehicle operation plan creation device, the constraint condition determination processing unit 405 (see FIG. 4) first performs the replacement source composition and variable i composition (determination target composition). Check whether the operation start station (location) on the first day of the specified period matches the operation end station (location) on the previous day, and if they match (step S701: Yes), define a variable j indicating the date. Then, the value of the variable j is set to the first day of the specified period (step S702).

  Next, it is confirmed whether or not the constraint condition related to the route is satisfied and the constraint condition related to the work are satisfied on the day of organization of the variable i and variable j (steps S703 and S704). If the constraint condition regarding the route is satisfied (step S703: Yes) and the constraint condition regarding the work is satisfied (step S704: Yes), the variable j is incremented (step S705). It is checked whether or not “j ≦ the last day of the specified period” holds (whether or not the variable j indicates a date within the specified period). If yes (S706: Yes), the processing of steps S703 to S706 is executed again. . That is, these steps S703 to S706 indicate an operation of confirming whether or not a constraint condition violation occurs as a result of replacement within the designated period of the organization of the variable i.

  Note that if an operation for exchanging the operation of one organization and the operation of another organization is performed while the vehicle operation plan is being created, a cell in which no route is set for the designated period of the organization of the exchange source and the organization other than the exchange source (Date) may be included. In this case, for a date for which no route is set, it is determined that the constraint conditions are satisfied in steps S703 and S704, and the process proceeds. Even if it is determined in this way, it is determined whether or not the constraint condition is satisfied in the route setting work (work for assigning a route to a cell for which a route has not been set at the time of replacement) that should be performed after the replacement. Must not.

  If it is determined in step S706 that the above condition is not satisfied (step S706: No), the operation end station on the last day of the specified period matches the operation start station on the next day in the composition of the exchange source and the composition of the variable i. If they match each other (step S707: Yes), it is determined that the composition of the variable i in the designated period is “exchangeable” (step S708), and the process is terminated.

  On the other hand, in the composition of the exchange source and the composition of variable i, if the operation start station on the first day of the specified period does not match the operation end station of the previous day (step S701: No), the composition of variable i and variable j In the day, when the restriction condition regarding the route or work is not satisfied (Step S703: No, or Step S704: No), and in the organization of the exchange source and the organization of the variable i, If the operation start stations on the next day do not match (step S707: No), it is determined that the composition of the variable i in the designated period is “non-exchangeable” (step S709), and the process is terminated. .

  As described above, in the vehicle operation plan creation device according to the present embodiment, the operation (period and organization) as the replacement source is selected in a state where the created vehicle operation plan or the vehicle operation plan being created is displayed. In such a case, an operation that does not cause a constraint violation even after replacement is extracted, and the extracted operation is displayed as a replacement destination candidate. In addition, regarding the operation of the exchange source and the operation of the exchange destination candidate, the organization information before and after the exchange is displayed together. As a result, the user can select the operation of the exchange partner from the exchange destination candidates that do not cause a constraint violation even if the exchange is performed, and when exchanging the operation plans of the two organizations, There is no need to consider whether a constraint violation occurs with the exchange. As a result, it becomes possible to easily perform the operation exchange of the composition satisfying the constraint condition, thereby improving the work efficiency and reducing the user's work load. In addition, work time can be reduced. Furthermore, before actually exchanging, the information of each organization before and after the exchange can be confirmed.

Embodiment 2. FIG.
In the second embodiment, a plan correction method (vehicle operation plan editing operation) different from the first embodiment will be described. The screen display example, device configuration, and operation flow are the same as in the first embodiment (see FIGS. 1 to 5). In principle, this embodiment is a method for exchanging the operation of one organization and the operation of another organization in an arbitrary period (a period specified by the user). In this method, the organization of the exchange destination is found by extending to the period including the previous day or the next day based on the selected period. In the present embodiment, description of operations common to those in the vehicle operation plan creation device of Embodiment 1 is omitted.

  Here, an operation procedure when the vehicle operation plan creation apparatus of the present embodiment displays the replacement source organization 301 and the replacement destination organization candidate list 308 on the editing work screen (see FIG. 3) will be described. FIG. 8 is a flowchart illustrating an example of a flow of display processing when the vehicle operation plan creation apparatus of the second embodiment displays the replacement source organization 301 and the replacement destination organization candidate list 308. In addition, the same step number is attached | subjected to the same process as the flow (refer FIG. 6) of the display process by the vehicle operation plan preparation apparatus of Embodiment 1. FIG. Description of the processing of the same step number as in FIG. 6 is omitted.

  When the processing of steps S601 to S607 shown in FIG. 8 is completed, the vehicle operation plan creation device determines whether there is a replaceable composition, that is, at least one composition that can be a replacement destination candidate in the processes of steps S601 to S607. It is confirmed whether it has been found (step S801). If there is a replaceable knitting (step S801: Yes), the process ends.

  On the other hand, if there is no exchangeable composition (step S801: No), it is determined whether the number of days in the designated period is an odd number. If the number is odd (step S802: Yes), a new designation is made for the designated period and the previous day of the period. A period is set (step S803), and steps S601 to S607 are executed for this new designated period to search for exchanges that can be exchanged. On the other hand, when the number of days in the designated period is not an odd number (step S802: No), the designated period and the day after the last day of the period are set as a new designated period (step S811). Steps S601 to S607 are executed as targets to search for exchanges that can be exchanged. The above process is repeated until a replaceable composition is found. As described above, in this embodiment, until a replaceable composition is found, the designated period is extended and updated (set as a new designated period), and a replaceable composition is searched for in the designated period after the update. .

  Note that the method for determining whether or not replacement is possible in step S604 is the same as in the first embodiment.

  If no exchangeable composition is found even after updating until the specified period reaches the maximum, the process ends at that point. Further, the determination condition in step S802 may be reversed (step S804 may be executed when the number of days is an odd number). In addition, when the specified period can be expanded only to either the front (the day before the first day of the specified period) or the rear (the day after the last day of the specified period), the expansion is performed regardless of the determination result of step S802. The specified period is extended in the possible direction, and the processes of steps S601 to S607 are executed.

  As described above, the vehicle operation plan creation apparatus according to the present embodiment, when no exchangeable train is found in the period specified by the user, extends the period one day at a time, while expanding the new period after expansion. The exchange destination candidate (exchangeable composition) search process shown in the first embodiment is continued until an exchangeable composition is found in FIG. As a result, similar to the first embodiment, it is possible to easily perform the operation exchange of exchangeable trains that satisfy the constraint conditions. Furthermore, the possibility of finding an exchangeable composition can be increased, and the difference from the originally created plan content can be made as small as possible.

Embodiment 3 FIG.
In the third embodiment, a plan correction method (vehicle operation plan editing operation) different from the first embodiment will be described. The screen display example and the device configuration are the same as in the first embodiment (see FIGS. 1 to 4). In principle, this embodiment is a method of exchanging the operation of one organization and the operation of another organization in an arbitrary period. However, when the organization of the exchange destination is not found, the selected period is further divided. It is a method of finding the organization of the exchange destination. In the present embodiment, description of operations common to those in the vehicle operation plan creation device of Embodiment 1 is omitted.

  FIG. 9 is a flowchart showing an operation example of the vehicle operation plan creation apparatus according to the third embodiment, and shows an operation example when exchanging the operation of a certain composition and the operation of another composition.

  When exchanging the operation of a certain organization and the operation of another organization, first, as in steps S501 and S502 shown in FIG. 5 of the first embodiment, the user creates the manual creation tab shown in FIG. 1 or FIG. In the screen, the exchange source organization and period are selected, and “exchange” is selected in the editing context menu 119 (steps S901 and S902). As a result, the vehicle operation plan creation device starts the editing work screen shown in FIG. 3, and at this time, searches for a knitted train that can be exchanged with a defined knitted train in the period specified in step S901. If there is a replaceable composition (found) (step S903: Yes), the found composition is displayed on the exchange destination candidate list 308 on the editing work screen. The user confirms the exchange destination candidate list 308, and if there is a composition to be exchanged (step S906: Yes), the user selects the composition to be exchanged and presses the setting button (step S907). When the setting button is pressed, the vehicle operation plan creation device exchanges the route / work information in the composition / period of the exchange source and the route / work information in the selected composition / period (step S908). Further, in the composition of the exchange source initially designated in step S901, it is confirmed whether there is a period in which the exchange has not been completed yet (step S910: No), and if not, the manual creation tab of FIG. 1 or FIG. , The route / work information in the composition / period of the exchange source is exchanged with the route / work information in the selected composition / period, and the operation ends.

  On the other hand, if there is a period in which the exchange has not been completed (step S910: Yes), the period in which the exchange has not been completed is set as a new designated period, and a train that can be exchanged within this new designated period is searched ( The same processing as that shown in FIGS. 6 and 7 is executed) (step S911). And it returns to step S903 and continues operation | movement.

  If it is determined in step S903 that there is no exchangeable composition in the designated period (step S903: No), it is confirmed whether the designated period is two days or more (step S904) and if it is two days or more (step S904). : Yes), the designated period until that time is divided into the first day and the remaining period, and the first day is set as a new designated period to search for exchanges that can be exchanged (search for exchanges that can be exchanged on the first day) (step S905). ). And it returns to step S903 and continues operation | movement. For the remaining period after the division, when a replaceable composition is found on the first day and an exchange operation is performed, a new designated period is set in step S911, and a search for a replaceable composition in this period is performed. Processing will be executed.

  When the user determines that there is no composition to be exchanged in step S906 (step S906: No), the cancel button is pressed by the user (step S909). In this case, the vehicle operation plan creation device returns to the screen display of the manual creation tab of FIG. 1 or FIG. If it is determined in step S904 that the specified period is not two days or longer (step S904: No), the replacement organization candidate list 308 (see FIGS. 1 and 2) is blank. The cancel button is pressed (step S909), and the screen returns to the manual creation tab screen shown in FIG.

  Here, a display method of the replacement source organization 301 and the replacement destination organization candidate list 308 on the editing work screen (see FIG. 3) in the vehicle operation plan creation apparatus of the present embodiment will be described. FIG. 10 is a flowchart illustrating an example of a flow of display processing when the vehicle operation plan creation device of the third exemplary embodiment displays the replacement source organization 301 and the replacement destination organization candidate list 308. In addition, the same step number is attached | subjected to the same process as the flow (refer FIG. 6) of the display process by the vehicle operation plan preparation apparatus of Embodiment 1. FIG. The description of the process with the same step number as in FIG. 6 is omitted.

  When the processing of steps S601 to S607 shown in FIG. 10 ends, the vehicle operation plan creation device determines whether there is a replaceable composition, that is, at least one composition of replacement destination candidates in the processes of steps S601 to S607. It is confirmed whether it has been found (step S1001). If there is a replaceable knitting (step S1001: Yes), the process is terminated. In this case, the found organization (replaceable organization) is displayed in the exchange destination organization candidate list 308.

  On the other hand, if there is no exchangeable composition (step S1001: No), it is determined whether or not the number of days in the specified period at the present time is one day. If it is one day (step S1002: Yes), exchangeable composition search processing is performed. Is finished, and a message to that effect is displayed and the process is terminated (step S1003). For example, a message that “cannot be exchanged because there is no exchangeable composition” is displayed. On the other hand, when the number of days in the designated period at the present time is two days or more (step S1002: No), the designated period is set to the first day of the designated period at that time (step S1004), and the designated period is changed. A message indicating that the search operation for exchangeable trains is to be continued is displayed (step S1005). For example, a message is displayed indicating that “a replaceable composition was not found, and a replaceable composition is searched only on the first day of the specified period”. Then, steps S601 to S607 are executed again for the new designated period after the setting change.

  Note that the method for determining whether or not replacement is possible in step S604 is the same as in the first embodiment (see FIG. 7).

  As described above, the vehicle operation plan creation apparatus according to the present embodiment divides the designated period into the first day and the remaining period when no exchangeable composition is found in the period designated by the user, It was decided to search for a train that can be exchanged in the period (first day and the remaining period). Also, if a replaceable formation is found on the first day after division and no exchangeable formation is found in the remaining period, if this remaining period can be further divided (if more than two days), then Dividing into the first day and the remaining period, the same search operation was continued. As a result, similar to the first embodiment, it is possible to easily perform the operation exchange of exchangeable trains that satisfy the constraint conditions. Furthermore, even when an exchangeable composition that completely satisfies the constraint condition is not found, it is possible to exchange the composition with a composition that partially satisfies the constraint condition.

  As described above, the vehicle operation plan creation device and the vehicle operation plan correction method according to the present invention are useful for creating and editing a vehicle operation plan table that represents train route information and work schedule information.
