Description

  Embodiments described herein relate generally to a vehicle operation plan creation device that creates a vehicle operation plan, an inspection plan, and a cleaning plan.

  In railways, it is necessary to create an operation plan that takes into account inspection, cleaning, operation, etc. for each vehicle to be operated. Conventionally, in a railway, each person in charge creates an inspection plan, a cleaning plan, an operation plan, and the like for each vehicle according to the restrictions of the person in charge. However, in reality, it is necessary to create a final operation plan while exchanging opinions between each person in charge of inspection, cleaning, and operation. For this reason, for example, a person who makes a plan later, such as an operation plan, may have a back work such as requesting the person in charge of the inspection or cleaning who created the plan to remake the plan. In fact, it takes a lot of time and cost.

  Conventionally, inspection plans, cleaning plans, and operation plans are created in this order, and each is often created individually. If an optimal plan cannot be created by creating an operation plan, an inspection that requires much effort is created. The plan and the cleaning plan must also be corrected, which causes rework and extra time. Therefore, there has been a demand for a vehicle operation plan creation device that can efficiently create an optimal vehicle operation plan for the entire inspection plan, cleaning plan, and operation plan.

  According to the embodiment, the vehicle operation plan creation device includes a first setting means, a first creation means, a second setting means, a second creation means, and a third creation means. The first setting means sets an inspection constraint condition as a constraint for inspecting the vehicle. The first creation means creates an inspection plan for the vehicle in accordance with the inspection constraint condition set by the first setting means. The second setting means sets a cleaning restriction condition as a restriction for cleaning the vehicle. The second creating means creates a cleaning plan in which the cleaning restriction condition set by the second setting means is applied to the inspection plan created by the first creating means. The third setting means sets an operation restriction condition as a restriction for operating the vehicle. The third creation means creates an operation plan in which the operation restriction condition set by the third setting means is applied to the cleaning plan created by the second creation means.

Hereinafter, embodiments will be described with reference to the drawings.
First, the configuration of the vehicle operation creation device according to the present embodiment will be described.
FIG. 1 is a diagram illustrating a hardware configuration example of the vehicle operation plan creation device 1. In the configuration example shown in FIG. 1, the vehicle operation plan creation device 1 includes a computer (electronic computer) and peripheral devices connected to the computer. The computer of the vehicle operation plan creation device 1 realizes various processes by the processor executing software. As shown in FIG. 1, the computer of the vehicle operation plan creation apparatus 1 includes a processor (CPU) 11, ROM 12, RAM 13, nonvolatile memory 14, HDD 15, and network interface 16. The vehicle operation plan creation device 1 also includes an operation unit 17, a display unit 18, a printer 19, and the like that are connected to a computer via an interface. The vehicle operation plan creation device 1 may be realized as a system in which a plurality of computers are connected. For example, setting information described later or a created plan may be stored in a server device as an external device.

  The processor 11 controls each unit in the vehicle operation plan creation device 1. The processor 11 implements various processing functions by using the RAM 13 and executing programs stored in the ROM 12, the nonvolatile memory 14, or the HDD 15. The ROM 12 is a non-rewritable non-volatile memory, and stores a control program, control data, and the like that control the basic operation of the computer. The RAM 13 is a working memory used when the processor 11 executes processing, for example. The nonvolatile memory 14 is a rewritable nonvolatile memory. The nonvolatile memory 14 stores, for example, an updatable control program or setting information. The HDD 15 is a large-capacity rewritable nonvolatile memory. The HDD 15 stores, for example, constraint conditions for creating various plans or created plans. The network interface 16 is an interface for connecting to a network. The network interface 16 is connected to a network for acquiring information from an external device via the network and outputting information such as the created plan to the external device.

  The operation unit 17 is a device through which an operator inputs information. For example, the operator inputs information to be reflected in the plan created by the operation unit. The display unit 18 is a device that displays information to the operator. For example, the display unit 18 displays information such as the created plan as an output of the created plan. The printer 19 forms an image on a recording medium such as paper. For example, the printer 19 prints the created plan on a recording medium such as paper as an output of the created plan.

Next, a function for creating a vehicle operation plan in the vehicle operation plan creation device 1 will be described.
FIG. 2 is a diagram schematically showing a processing function for creating an operation plan in the vehicle operation plan creation apparatus 1.
The vehicle operation plan creation device 1 realizes an operation plan creation function by the processor 11 executing a program. The vehicle operation plan creation device 1 includes an inspection plan unit 101, a cleaning plan unit 102, and an operation plan unit 103 as a vehicle operation plan creation function (operation plan creation unit). The inspection planning unit 101, the cleaning planning unit 102, and the operation planning unit 103 perform inspection planning and cleaning based on constraint conditions (conditions that must be observed) and desired conditions (conditions that should be observed if possible). Create plans and operation plans.

  Each planning unit 101, 102, 103 wants a condition that the person in charge inputs through the operation unit 17 with the inspection condition, the cleaning condition, the operation condition for the vehicle, and the plan created in the previous planning unit as a constraint condition. As a condition, an inspection plan, a cleaning plan, and an operation plan are created. Each planning unit 101, 102, 103 creates each plan by an algorithm that comprehensively finds combinations that satisfy the given constraint conditions and satisfy the desired conditions as much as possible. For example, an algorithm for creating each plan in each planning unit 101, 102, 103 can be an optimization processing algorithm that sets the violation of the constraint condition to 0 and minimizes the violation of the desired condition.

  Conditions to be observed as inspections for vehicles are inspection restriction conditions 121, conditions to be protected as cleaning for vehicles are cleaning restriction conditions 122, and conditions to be protected as vehicle operations are operation restriction conditions 123. The vehicle operation plan creation apparatus 1 is assumed to store the inspection restriction condition 121, the cleaning restriction condition 122, and the operation restriction condition 123 in a storage device such as the HDD 15 as setting information. Further, the vehicle operation plan creation device 1 may refer to the inspection constraint condition 121, the cleaning constraint condition 122, and the operation constraint condition 123 stored in an external device connected via a network or the like. Desired conditions 131, 132, and 133 are conditions that are to be realized if the person in charge of plan creation is possible.

  For example, the inspection constraint condition 121 is a restriction on the inspection item itself, and includes, for example, an executable place, a required time, an inspection cycle, and the like. The desired condition (desired inspection condition) 131 relating to the inspection is, for example, a place where the inspection is to be performed or a date and time when the inspection is to be performed. The cleaning restriction condition 122 is a restriction on the cleaning item itself, and includes, for example, an executable place, a required time, a cleaning cycle, and the like. The desired condition (desired cleaning condition) 132 regarding the cleaning is, for example, a place where cleaning is desired to be performed or a date when cleaning is desired. The operation restriction condition 123 is a restriction on the operation itself, and includes, for example, a place and time uniquely determined for the operation. The desired condition (desired operation condition) 133 regarding the operation is, for example, information indicating that a specific operation is desired for a specific vehicle.

  In addition to the constraint conditions such as inspection, cleaning, and operation, each planning unit 101, 102, 103 also uses the already created plan (the plan created by the previous planning unit) itself as the constraint condition. For example, as in the configuration example shown in FIG. 2, the vehicle operation plan creation device 1 that creates a plan in the order of an inspection plan, a cleaning plan, and an operation plan, the cleaning plan unit 102 includes not only a cleaning constraint condition, The inspection plan created by the inspection plan unit 101 is also a constraint condition to be observed. In addition, the operation planning unit 103 sets not only the operation restriction conditions but also the cleaning conditions (inspection and cleaning plan) created by the cleaning planning unit 102 as the restriction conditions to be observed.

  However, the inspection planning unit 101, the cleaning planning unit 102, and the operation planning unit 103 can be operated individually. That is, the inspection planning unit 101, the cleaning planning unit 102, and the operation planning unit 103 independently create an inspection plan, a cleaning plan, and an operation plan, without using the plans created by other planning units as constraints. It is also possible to do. Further, the order in which the inspection planning unit 101, the cleaning planning unit 102, and the operation planning unit 103 create the inspection plan, the cleaning plan, and the operation plan can be changed to an arbitrary order (for example, an order designated by the person in charge). May be.

  In the configuration example illustrated in FIG. 2, the cleaning plan unit 102 creates a cleaning plan in consideration of the inspection plan after the inspection plan unit 101 creates the inspection plan. That is, the cleaning plan unit 102 needs to create a cleaning plan that satisfies the cleaning constraint condition and the inspection plan created by the inspection plan unit 101. Therefore, the cleaning plan unit 102 determines whether or not a cleaning plan that satisfies the cleaning constraint condition and the inspection plan can be created.

  When a cleaning plan that satisfies the cleaning constraint condition and the inspection plan cannot be created, the vehicle operation plan creation device 1 creates the inspection plan again. The inspection plan unit 101 creates an inspection plan in consideration of inspection constraint conditions and desired inspection conditions. If it is assumed that the inspection constraint condition cannot be changed, the vehicle operation plan creation device 1 accepts re-input of the desired inspection condition. When the desired inspection conditions are re-input, the inspection planning unit 101 recreates an inspection plan that takes into account the re-input desired inspection conditions. By such processing, the vehicle operation plan creation device 1 repeatedly executes re-creation of the inspection plan until a cleaning plan that satisfies the cleaning constraint condition and the inspection plan can be created.

  In addition, the operation plan unit 103 needs to create an operation plan that satisfies the operation restriction condition and the cleaning plan created by the cleaning plan unit 102. For this reason, when an operation plan that satisfies the operation constraint condition and the cleaning plan cannot be created, the vehicle operation plan creation device 1 creates the cleaning plan again. Assuming that the inspection constraint condition and the cleaning constraint condition cannot be changed, the vehicle operation plan creation device 1 accepts the desired cleaning condition or the re-input of the desired inspection condition. When the desired cleaning condition or the desired inspection condition is re-input, the cleaning planning unit 102 or the inspection planning unit 101 recreates a cleaning plan or inspection plan that takes into account the re-entered desired cleaning condition or desired inspection condition. By such processing, the vehicle operation plan creation device 1 repeatedly executes the cleaning plan or the inspection plan re-creation until an operation plan that satisfies the inspection constraint condition, the cleaning constraint condition, and the cleaning plan (cleaning and inspection plan) can be created. To do.

  In order to create an operation plan, it is necessary to obey the operation restriction conditions that must be observed (for example, the connection between the place of operation and the place) and the desired operation conditions (if possible, such as assigning an operation on a certain vehicle). ) And exist. In the inspection plan unit 101 and the cleaning plan unit 102, an inspection plan or a cleaning plan may be created by assigning a temporary operation plan so as to satisfy an operation restriction condition that must be observed. By such processing, when the operation plan unit 103 creates an operation plan, it is possible to prevent in advance at the time of creation of the inspection plan or cleaning plan that a plan that does not satisfy the operation constraint condition is created. It becomes.

Next, the flow of processing for creating an operation plan will be described.
FIG. 3 is a flowchart for explaining an operation plan creation process.
The vehicle operation plan creation device 1 starts creating an operation plan in response to an operation by the operation unit 17. When creating an operation plan, the processor 11 of the vehicle operation plan creation apparatus 1 first performs a process of creating an inspection plan (inspection plan creation process). The processor 11 acquires the inspection constraint condition (step S11). The processor 11 reads the inspection constraint condition from the HDD 15. Further, the processor 11 may acquire the inspection constraint condition from an external device that can communicate via the network interface. Further, the processor 11 receives an input of desired inspection conditions through the operation unit 17 (step S12). For example, if there is a condition desired by the person in charge of the inspection in the inspection plan, the desired inspection condition is input by the operation unit 17. If there is no desired inspection condition, a message indicating that there is no hope may be input by the operation unit 17.

  When the inspection constraint condition and the desired inspection condition are acquired, the processor 11 creates an inspection plan that satisfies the inspection constraint condition and satisfies the desired inspection condition as much as possible (step S13). Creation of such an inspection plan is realized by an optimization algorithm that sets the violation of the inspection constraint condition to 0 and minimizes the violation of the desired inspection condition. The processor 11 outputs the created inspection plan (step S14). For example, the processor 11 stores the created inspection plan in the HDD 15 and displays the stored inspection plan on the display unit. The processor 11 may print the created inspection plan by a printer connected via an interface.

  Further, the processor 11 accepts a request for correcting the output inspection plan (step S15). For example, if there is a point to be corrected in the output inspection plan, the correction point is input by the operation unit 17. If there is no correction point in the inspection plan, the operation unit 17 may input that there is no correction (or determination of the inspection plan). When the correction point is input, the processor 11 reflects the input correction point on the desired inspection condition, and executes the processes of steps S12 to S15. Further, the processor 11 may re-plan the inspection plan using the input correction points as inspection constraint conditions. When correction points are input, matters related to the correction points input in the re-created inspection plan may be highlighted or displayed in a different color.

  When the inspection plan is finalized (step S15, NO), the processor 11 performs a process of creating a cleaning plan (cleaning plan creation process). Here, the processor 11 creates a cleaning plan reflecting the created inspection plan. In the present embodiment, in order to create an inspection plan, the processor 11 sets not only the cleaning constraint condition for performing cleaning independently but also the inspection plan itself as a constraint condition. That is, the processor 11 creates a cleaning plan (cleaning and inspection plan) using the cleaning constraint condition and the inspection plan for performing cleaning independently as a constraint condition.

  That is, the processor 11 acquires a cleaning restriction condition for performing cleaning independently (step S16). For example, the processor 11 reads the cleaning restriction condition from the HDD 15. Further, the processor 11 may acquire the cleaning restriction condition from an external device that can communicate via the network interface 16. Furthermore, the processor 11 receives an input of desired inspection conditions through the operation unit 17 (step S17). For example, if there is a condition desired by the person in charge of cleaning in creating the cleaning plan, the desired cleaning condition is input by the operation unit 17. If there is no desired cleaning condition, the operation unit 17 may input that there is no request.

  When the cleaning restriction condition and the desired cleaning condition are acquired, the processor 11 creates a cleaning plan (cleaning and inspection plan) that satisfies the cleaning restriction condition and the inspection plan and satisfies the desired cleaning condition as much as possible (step S18). ). The creation of such a cleaning plan is realized by an optimization algorithm that sets the violation of the cleaning constraint condition and the inspection plan to 0 and minimizes the violation of the desired cleaning condition. The processor 11 outputs the created cleaning plan (step S20) when the cleaning plan using the cleaning constraint condition and the inspection plan as the constraint condition can be created (step S19, YES). For example, the processor 11 stores the created cleaning plan in the HDD 15 and displays the stored cleaning plan on the display unit 18. Further, the processor 11 may print the created cleaning plan by a printer connected via an interface.

  Moreover, the processor 11 receives the correction request | requirement of the output cleaning plan (step S21). For example, if there is a point to be corrected in the output cleaning plan, the correction point is input by the operation unit 17. When there is no correction point in the cleaning plan, the operation unit 17 may input that there is no correction (or the cleaning plan is confirmed). When the correction point is input, the processor 11 reflects the input correction point on the desired cleaning condition, and executes the processes of steps S17 to S21. Further, the processor 11 may re-create the cleaning plan with the input correction point as a constraint condition. In addition, when correction points are input, items related to the correction points input in the re-created cleaning plan are highlighted or displayed in another color on the display unit 18 or printed on paper. You can do it.

  Further, when the cleaning plan with the cleaning constraint condition and the inspection plan as the constraint conditions cannot be created (NO in step S19), the processor 11 prompts the user to re-enter the desired inspection condition, and returns to step S12 to set the inspection plan. Recreate it. In this case, the processor 11 creates an inspection plan in consideration of the inspection constraint conditions, the cleaning constraint conditions, and the desired inspection conditions that are re-input. In addition, when the plan that satisfies the inspection constraint condition and the cleaning constraint condition is impossible, the processor 11 may notify that the constraint condition cannot be realized, and stop the operation plan creation process.

  When an inspection plan that takes into account the re-input desired inspection conditions is created, the processor 11 receives input of the desired cleaning conditions again. When the desired inspection conditions are re-input, the processor 11 recreates a cleaning plan (inspection and cleaning plan) that takes into account the re-input desired cleaning conditions. By such processing, the vehicle operation plan creation device 1 repeatedly executes re-creation of the inspection plan until a cleaning plan that satisfies the cleaning constraint condition and the inspection plan (a plan that satisfies the inspection constraint condition) can be created.

  When the cleaning plan is determined (step S21, NO), the processor 11 performs a process (operation plan creation process) for creating an operation plan (inspection, cleaning, and operation plan). Here, the processor 11 creates an operation plan reflecting the created cleaning plan as an operation plan. In the present embodiment, in order to create an operation plan, the processor 11 uses not only the operation restriction condition as a restriction on the operation itself but also the cleaning plan itself as the restriction condition. That is, the processor 11 creates an operation plan (inspection, cleaning, and operation plan) as a constraint condition that should observe the constraint on the operation itself and the cleaning plan.

  In other words, the processor 11 acquires an operation restriction condition as a restriction on the operation itself (step S22). For example, the processor 11 reads the operation restriction condition from the HDD 15. Further, the processor 11 may acquire the operation restriction condition from an external device that can communicate via the network interface 16. Further, the processor 11 receives an input of desired operation conditions through the operation unit 17 (step S23). For example, if there is a condition desired by the person in charge of operation in creating the operation plan, the desired operation condition is input by the operation unit 17. In the case where there is no desired operation condition, a message indicating that there is no hope may be input by the operation unit 17.

  When the operation restriction condition and the desired operation condition are acquired, the processor 11 creates an operation plan (inspection, cleaning, and operation plan) that satisfies the operation restriction condition and the cleaning plan and satisfies the desired operation condition as much as possible ( Step S24). The creation of such an operation plan is realized by an optimization algorithm that sets the violation of the operation restriction condition and the cleaning plan to 0 and minimizes the violation of the desired operation condition. The processor 11 outputs the created operation plan (step S26) when the operation plan with the operation constraint condition and the cleaning plan as the constraint condition can be created (step S25, YES). For example, the processor 11 stores the created operation plan in the HDD 15. The processor 11 displays the created operation plan on the display unit 18 as an output of the created plan, or prints it on paper by a printer connected via an interface.

  Further, the processor 11 accepts a request for correcting the output operation plan (step S26). For example, if there is a point to be corrected in the output operation plan, the correction point is input by the operation unit 17. If there is no correction point in the operation plan, the operation unit 17 may input that there is no correction (or determination of the operation plan). When the correction point is input, the processor 11 reflects the input correction point on the desired operation condition, and executes the processes of steps S23 to S27. Further, the processor 11 may re-create the operation plan using the input correction point as a constraint condition. Further, when correction points are input, items related to the correction points input in the re-created operation plan are highlighted or displayed in a different color on the display unit 18 or printed on paper. You can do it.

  Further, when the operation plan with the operation constraint condition and the cleaning plan as the constraint condition cannot be created (step S25, NO), the processor 11 prompts the user to re-enter the desired inspection condition or the desired cleaning condition, and returns to step S12. Re-create inspection plan and cleaning plan. In this case, the processor 11 creates an operation plan by adding the desired inspection condition or the desired restriction condition that is re-input to the inspection restriction condition, the cleaning restriction condition, and the operation restriction condition. In addition, when a plan that satisfies the inspection constraint condition, the cleaning constraint condition, and the operation constraint condition is impossible, the processor 11 notifies that the constraint condition cannot be realized, and cancels the operation plan creation process. Also good.

  When the cleaning plan is re-created, the processor 11 receives input of desired operation conditions again. When the desired operation conditions are re-input, the processor 11 recreates an operation plan (inspection, cleaning, and operation plan) that takes into account the re-input desired operation conditions. By such processing, the vehicle operation plan creation device 1 creates an operation plan that satisfies the operation constraint condition and the cleaning plan (a plan that satisfies the inspection constraint condition and the cleaning constraint condition) (step S28). According to the processing as described above, the operator can easily create a satisfactory operation plan by repeatedly inputting desired conditions or corrections.

  As described above, the vehicle operation plan creation device creates an inspection plan that satisfies the inspection restriction condition and satisfies the desired inspection condition as much as possible, satisfies the created inspection plan and the cleaning restriction condition, and satisfies the desired cleaning condition. A cleaning plan that satisfies as much as possible is created, and an operation plan (operation plan) that satisfies the created cleaning plan and operation constraint conditions and satisfies desired operation conditions as much as possible is generated. Thereby, the vehicle operation plan creation device can easily create the operation of the vehicle that meets various conditions of inspection, cleaning, and operation.

  In addition, in order to create a vehicle operation plan, it is necessary to ensure that the operation restriction conditions (for example, the connection between the place of operation and the place) that must be observed and the desired operation condition (if possible, to assign the operation on a certain vehicle) Limitations). For this reason, the processor 11 as the inspection plan unit 101 and the cleaning plan unit 102 may create a test plan or a cleaning plan by assigning a temporary operation plan so as to satisfy an operation constraint condition that must be observed. good. According to such a process, when the processor 11 as the operation plan unit 103 creates an operation plan, it is preliminarily created at the time of creation of the inspection plan or the cleaning plan that a plan that does not satisfy the operation restriction condition is created. It becomes possible to prevent.

Next, an operation plan rework process (operation plan re-creation process) will be described.
For example, in a railway or the like, an unforeseen situation may occur, such as a timetable disruption in actual work. When an unexpected situation occurs, naturally, there are many cases where the business (vehicle operation) cannot be performed according to the operation plan created by the vehicle operation plan creation device 1. In such a case, the vehicle operation plan creation device 1 has a function of refining the operation plan. For example, in a transportation system such as a railroad, securing of transportation capacity is the most important matter for the time being when there is a diamond disruption. The vehicle operation plan creation device 1 assigns which operation to which vehicle when the vehicle is not able to reach the planned place due to the disruption of the schedule and the vehicle ends (ends the day's work). It has a function of confirming the next day shipment such as whether to secure operation, that is, a function of recreating the next sunrise storage (operation) plan.

FIG. 4 is a diagram for schematically explaining the next day delivery confirmation function (reproduction function of the delivery plan) in the vehicle operation plan creation device 1.
The vehicle operation plan creation device 1 has a delivery plan re-creation function (a delivery plan re-creation unit) 160. The delivery plan re-creation function 160 is a function realized by the processor 11 executing a program, similarly to the operation plan creation function. As shown in FIG. 4, the exit plan re-creation unit 160 of the vehicle operation plan creation device 1 includes the original operation plan 161 that is the original plan and the detained position information 162 of each vehicle including the disturbance that has occurred in the actual operation. Then, the next sunrise storage plan (recreated operation plan) 164 is recreated based on the constraint condition 163.

  The indwelling position information 162 for each vehicle is acquired from an external device. In addition, the operator may be able to input and confirm the detention position by changing the operation unit 17 so that the vehicle can be moved using night forwarding (operation other than normal operation). . Note that the constraint condition 163 includes an operation constraint condition and an inspection constraint condition that a vehicle whose inspection period has expired is not operated.

FIG. 5 is a flowchart for explaining the flow of the re-creation process of the shipping plan.
When a plan change occurs due to a schedule disruption or the like, the processor 11 of the vehicle operation plan creation apparatus 1 executes a re-creation process of the delivery plan in order to correct the operation plan. The delivery plan re-creation process includes an inspection plan re-creation process, a cleaning plan re-creation process, and an operation plan re-creation process, and each plan re-created in turn is a re-created delivery plan. In the re-creation process of each plan, a plan with a smaller change amount than the original plan is re-created as much as possible by referring to the original plan. In the re-creation process of each plan, the plan is re-created repeatedly while adding corrections that take into account information input by the operator through the operation unit 17. In the process example shown in FIG. 5, the process of creating each plan is executed until the delivery (operation) plan is completed.

  That is, when re-creating an inspection (or cleaning, operation) plan, the processor 11 first acquires the original inspection plan (step S31). Furthermore, the processor 11 acquires indwelling position information indicating the current position of the vehicle (the position where the vehicle is placed) (step S32). Indwelling position information is obtained from an external device via the network interface 16. In this case, the network interface 16 functions as a detention position information acquisition unit.

  Furthermore, the processor 11 acquires a constraint condition (inspection, cleaning, or operation constraint condition) (step S33). For example, the processor 11 reads the constraint condition from the HDD 15. Further, the processor 11 may acquire a constraint condition from an external device. In this state, the processor 11 accepts input of desired conditions (desired inspection conditions, desired cleaning conditions, or desired operation conditions) by the operation unit 17 (step S34).

  When the desired condition is acquired, the processor 11 re-creates a plan that satisfies the detention position and the constraint condition and satisfies the desired condition as much as possible based on the original plan (step S35). Such re-creation of the plan is realized by an optimization algorithm that sets the violation of the constraint condition to 0 and minimizes the violation of the desired condition. The processor 11 outputs the recreated plan (step S36). For example, the processor 11 displays the recreated plan on the display unit 18 or prints it with the printer 19. In this case, the processor 11 highlights the portion changed from the original plan or displays it in another color (specific color). Further, the processor 11 may display a list of locations changed from the original plan.

  In addition, the processor 11 receives a request for correcting the output plan (step S37). For example, if there is a point to be corrected in the output plan, the operator inputs the correction point through the operation unit 17. When the correction point is input (step S37, YES), the processor 11 reflects the input correction point on the desired condition and recreates the plan again. Further, when outputting the re-created plan, the processor 11 may highlight or display items related to the correction points input in the re-created plan in different colors.

  When the re-created plan is confirmed (step S37, NO), the processor 11 determines whether or not the re-creation of the operation plan as the next sunrise storage plan is completed (step S38). For example, when a plan is created in the order of inspection, cleaning, and operation, the processor 11 determines whether or not the next sunrise storage plan is completed depending on whether or not the operation plan is completed. In this case, since the processor 11 recreates the cleaning plan next when the inspection plan is finalized, the processor 11 determines that the next sunrise storage plan is incomplete, and proceeds to the cleaning plan recreation processing. When the cleaning plan is finalized, the operation plan is re-created next, so it is determined that the next sunrise storage plan is incomplete, and the operation plan re-creation processing proceeds.

  If the next sunrise storage plan is incomplete, that is, if there is a plan to be re-created next (step S38, NO), the processor 11 returns to step S31 and receives information according to the plan to be re-created next. To get. When the next sunrise storage plan (re-creation of the operation plan) is completed (step S38, YES), the processor 11 stores the re-created operation plan in the HDD 15 or the like as the next sunrise storage plan (step S39), and the next day Finalize the shipping plan.

  As described above, the vehicle operation plan creation device not only creates a vehicle operation plan in consideration of inspection constraint conditions, cleaning constraint conditions, operation constraint conditions and desired conditions, but also disturbs actual vehicle operation. When it occurs, the original plan and the current detention position information are acquired, and a new plan that is close to the original plan (less changes from the original plan) is added with various constraints and desired conditions. Recreate it.
