[Solution] The reception department receives planning period information, worker information, work constraint information, and operation information of the trains to be worked on. The planning department uses the received information and a work plan formulation model to formulate a work plan for workers during the planning period.

[0012] Hereinafter, embodiments according to the present disclosure will be described with reference to the drawings.

[0013] <First Embodiment> The work schedule proposing device according to the first embodiment of the present disclosure has a function of formulating a work schedule for workers who perform maintenance work including cleaning inside trains, and is provided with a function aimed at equalizing the work burden of the workers when formulating the work schedule. The maintenance work inside a train herein refers to work performed at a predetermined station such as a turnaround station or a terminal station of the train while the train is stopped, so as to ensure passenger comfort. Specific examples of the maintenance work inside the train include collection of garbage falling on seats and floors, cleaning of seats, floors and toilets, disinfection of door knobs, changing the orientation of seats, and work of returning the inclination of backrests to the reference position. Such maintenance work is not necessarily performed on all trains stopping at the station, but is performed on predetermined trains subject to work (for example, Shinkansen and limited express trains). The work schedule proposing device of the first embodiment formulates a work schedule for workers who perform maintenance work for each station where such in-train maintenance work is performed.

[0014] Hereinafter, the configuration of the work schedule proposing device according to the first embodiment will be described. The work schedule proposing device of the first embodiment is a computer device, and as shown in Figure 1, includes an arithmetic device 10 and a storage device 20. The storage device 20 is provided with a storage medium that stores data and a computer program (hereinafter also referred to as a program) 21. There are multiple types of storage devices such as magnetic disk devices and semiconductor memory elements, and further, there are multiple types of semiconductor memory elements such as RAM (Random Access Memory) and ROM (Read Only Memory), so there are a large number of types. The work schedule proposing device 1 is provided with a plurality of storage devices with different uses, but the type and number thereof are not limited herein, and descriptions thereof are omitted. In addition, the plurality of storage devices provided in the work schedule proposing device 1 are collectively referred to as the storage device 20 without distinction. Note that the work schedule proposing device 1 is also connected to, for example, a database (storage device) 5, and writing of information to the database 5 and reading of information from the database 5 are performed as necessary, but in the following description, descriptions regarding writing of information to the database 5 and reading of information from the database 5 are omitted.

[0015] The arithmetic device 10 is configured by a processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit). The arithmetic device 10 can have various functions based on the program 21 by reading and executing the program 21 stored in the storage device 20. Here, the arithmetic device 10 includes, as functional units related to the formulation of worker work schedules, a receiving unit 11, an acquisition unit 12, a planning unit 13, and an output unit 14.

[0016] The reception unit 11 receives planning period information, worker information, work constraint information, and operation information. Planning period information is information that represents the planning period, which is the period covered by the work plan to be formulated. The planning period is specified by future dates in predetermined periods, such as weekly or monthly. Worker information is information that represents the workers who are the subject of the work plan and who perform maintenance work, including cleaning the train interior. Information included in worker information includes, for example, name, worker identification information, and worker attribute information (years of experience, expertise in cleaning and maintenance, health status, etc.). Work constraint information is information that represents the work constraints of workers during the planning period. There are several types of work constraints. One type of work constraint is, for example, working conditions such as working hours and holidays based on the Labor Standards Act. Another type of work constraint is, for example, the worker's requested days for work (leave), working hours based on childcare or elder care, and the number of days of leave that a worker can take. Operation information is information related to the operation of the trains that are the subject of work during the planning period. The operational information includes the time and location of the train's arrival at the station where maintenance work will be performed, the stopping time (i.e., information related to the available work time for maintenance), train identification information to identify the train, and the type of train (name, model, etc.). Here, for example, this information is transmitted from the computer device 3, as shown in Figure 1, to the work schedule proposal device 1, and the reception unit 11 receives the transmitted information. In addition, for each station where maintenance work is performed on the train, the above-mentioned information is linked to each other and transmitted from the computer device 3 to the work schedule proposal device 1.

[0017] In other words, the work schedule proposal device 1 is connected to the computer device 3 via an information and communication network. The computer device 3 is, for example, a device operated by the person in charge 2 who is responsible for formulating the work schedules of workers, and is incorporated into an attendance management system that manages the attendance of workers. Here, the computer device 3 functions as an input device for inputting information and commands to the work schedule proposal device 1. That is, the computer device 3 and the work schedule proposal device 1 operate in cooperation with each other. As a result, information that is input into the computer device 3 or read from the attendance management system's database by the person in charge 2 is transmitted from the computer device 3 to the work schedule proposal device 1 and received by the reception unit 11 of the work schedule proposal device 1. The cooperation between the computer device 3 and the work schedule proposal device 1 is performed by an application program (app) that gives the computer device 3 the function to cooperate with the work schedule proposal device 1. Alternatively, the cooperation (connection) between the computer device 3 and the work schedule proposal device 1 may be performed by a browser (software for viewing information on the internet). Whether the communication between computer device 3 and work schedule proposal device 1 is performed via an application or a browser is set as appropriate by the designer of work schedule proposal device 1, and is not limited to this.

[0018] The acquisition unit 12 acquires the information to be acquired from a predetermined information source 4. Here, the information to be acquired is information used to estimate the workload of maintenance work on the train under maintenance, and the type of information to be acquired is predetermined. For example, vehicle attribute information can be used. Vehicle attribute information is information that represents the attributes of the vehicles that make up the train under maintenance during the planned period (for example, vehicles with toilets or special vehicles (green cars)). Such information can be acquired, for example, from the database of the train operation management system that manages train operations. In other words, vehicle attribute information is acquired from the train operation management system as information source 4. In addition, information used to estimate the workload of maintenance work on the train under maintenance can be, for example, weather forecast information for the planned period. Weather forecast information can be acquired, for example, from a system that provides weather forecasts at the Japan Meteorological Agency or a weather-related company, using information source 4.

[0019] The planning unit 13 uses the information received by the reception unit 11, the information acquired by the acquisition unit 12, and the work plan formulation model to formulate a work plan for the workers. The work plan here includes information on the workers' workdays and work hours on those workdays, as well as information on the trains to which maintenance work will be assigned to the workers on those workdays. Work hour information refers to information indicating which of the multiple work hours set within a day the worker will work during.

[0020] The work plan formulation model is a model generated using AI (Artificial Intelligence) technology. It takes information received by the reception unit 11 and information acquired by the acquisition unit 12 as input, and outputs the work plan for workers for the planning period represented in the input planning period information. The basic formulation method used by this work plan formulation model to formulate workers' work plans is not limited here, and a detailed explanation is omitted. However, here, the work plan formulation model is a model that can formulate workers' work plans with the aim of leveling the workload of workers by learning the following data. In other words, the work plan formulation model learns data relating to train usage-related information and actual information on the amount of maintenance work performed on trains. Train usage-related information is information that represents matters related to the amount of maintenance work performed on trains, and includes, for example, occupancy rate, train attributes, and passenger attributes. For example, it is assumed that when the number of passengers on a train increases, the amount of garbage and dirt on the train increases, and the amount of maintenance work increases. For this reason, the occupancy rate, which is related to the number of passengers, is related to the amount of maintenance work performed. Furthermore, for example, if there are many passengers traveling for tourism purposes, it is assumed that increased eating and drinking on the train will lead to more trash and dirt on the train, thus increasing the workload for maintenance work. For this reason, train attributes that can estimate the purpose of passenger use are related to the workload for maintenance work. In addition, for example, it is sometimes observed that office workers returning home late at night drink alcohol on the train, and in such cases, it is assumed that trash and dirt on the train will also increase, thus increasing the workload for maintenance work. For this reason, passenger attributes are related to the workload for maintenance work. It should be noted that train usage-related information only needs to represent information that relates to the workload for maintenance work on the train, and is not limited to the occupancy rate, train attributes, and passenger attributes mentioned above, but may also include, for example, information on the time of day of operation.

[0021] Furthermore, in the first embodiment, an acquisition unit 12 is provided, and the acquisition unit 12 may acquire weather forecast information for the planned period. For example, if it is raining or snowing, it is assumed that the floor inside the train will get wet and dirty, increasing the amount of maintenance work required. For this reason, the weather in the area where the train operates is also related to the amount of maintenance work required.

[0022] The work schedule planning model is generated by learning the relationship data between the train usage-related information and the actual amount of maintenance work performed, as described above, so that it can estimate the amount of maintenance work performed on each train using the train usage-related information. Furthermore, in the first embodiment, if weather forecast information for the planning period is acquired by the acquisition unit 12, the work schedule planning model can estimate the amount of maintenance work performed on each train using the weather forecast information in addition to the train usage-related information. In other words, the work schedule planning model also learns the relationship data between weather conditions and the actual amount of maintenance work performed on trains. The work schedule planning model is also provided with relationship data between the amount of maintenance work and the number of workers required for that amount of work (hereinafter referred to as the "number of workers calculation data"). The work schedule planning model has a function to calculate the number of workers corresponding to the estimated amount of maintenance work performed on each train using the number of workers calculation data, and to determine which train to assign to each worker using the calculated number of workers for each train.

[0023] The work schedules formulated using this work schedule model include the allocation of a number of workers to each train based on the estimated workload for that train. In other words, more workers are allocated to trains estimated to have a heavy workload, and fewer workers are allocated to trains estimated to have a light workload, thus formulating a work schedule that allocates the number of workers to each train based on the estimated workload. Therefore, the work schedule model can formulate work schedules that reduce variations in the workload per worker between trains due to weather and train usage, and that aim to equalize the workload for workers.

[0024] In the first embodiment, the system may be configured to formulate a work schedule for workers using a work schedule formulation model, thereby further leveling the workload of workers. Specifically, when vehicle attribute information is acquired by the acquisition unit 12, the work schedule formulation model is further trained to learn the relationship between the attributes of the train's vehicles and the actual data on the amount of maintenance work performed. As a result, the work schedule formulation model is generated to be able to estimate the amount of maintenance work performed on each vehicle constituting the train being worked on, using the vehicle attribute information. The work schedule formulation model further determines which vehicle each worker will be responsible for in the train to which maintenance work is assigned, using the estimated amount of maintenance work for each vehicle and the data for calculating the number of workers. As a result, the work schedule for workers based on the work schedule formulation model can reduce variations in the workload per worker between trains due to weather and train usage, as well as variations in the workload per worker between vehicles within a train, thereby further leveling the workload.

[0025] The output unit 14 outputs work plan information representing the work schedules of workers formulated by the planning unit 13. The output destination for the work plan information is predetermined, for example, a computer device 3. In the first embodiment, the computer device 3 is incorporated into an attendance management system that manages the attendance of workers. As a result, the work plan information output from the output unit 14 to the computer device 3 includes, for example, the work schedules of all workers. Upon receiving the work plan information, the computer device 3 displays the information contained in the work plan information by controlling the display operation of a connected display device or a built-in display device. For example, Figure 2 shows an example of a work schedule display that shows a list of work schedules for all workers on a monthly basis. Alternatively, the computer device 3 may control the display so that a work schedule showing a list of monthly or weekly work schedules for each worker is displayed on the display device. Furthermore, as shown in Figure 3, the computer device 3 may control the display so that information representing the assigned train and vehicle for each workday for each worker is displayed on the display device.

[0026] Furthermore, while individual work schedule information for each worker 6 performing maintenance work may be transmitted from the computer device 3 to the worker 6's terminal device 7, the output unit 14 may output the individual work schedule information for each worker 6 to the worker 6's pre-registered terminal device 7. The terminal device 7 may be a smartphone, a notebook personal computer, or a desktop personal computer. In this case, for example, the individual work schedule of worker 6 may be displayed on the display device of the terminal device 7 on a monthly or weekly basis, or information such as that shown in Figure 3 may be displayed on the display device of the terminal device 7.

[0027] The work schedule proposal device 1 of the first embodiment is configured as described above. Next, an example of the operation of the work schedule proposal device 1 will be explained using the flowchart in Figure 4. Figure 4 can also be said to represent an example of a work schedule proposal method.

[0028] For example, the reception unit 11 receives planning period information, worker information, work constraint information, and operation information, and the acquisition unit 12 acquires the information to be acquired from a predetermined information source 4 (step 101). The planning period information, worker information, work constraint information, and operation information received by the reception unit 11 are related to each other. The timing of when the acquisition unit 12 acquires the information is predetermined, and for example, information acquisition is performed when the reception unit 11 receives the information described above.

[0029] Subsequently, the planning unit 13 uses the received and acquired information, along with the work plan formulation model, to formulate a work plan for the workers (step 102). The formulated work plan also includes information on the trains to which maintenance work will be assigned to the workers during the planning period. Then, the output unit 14 outputs work plan information representing the workers' work plans (step 103).

[0030] The work schedule proposal device 1 of the first embodiment, having the configuration described above, can formulate a work schedule for workers that takes into account the amount of maintenance work for each train, which varies depending on the weather and usage conditions. As a result, the work schedule proposal device 1 can reduce the variation in the workload per worker between trains due to weather and train usage conditions.

[0031] <Second Embodiment> A second embodiment relating to this disclosure is described below. In the description of the second embodiment, components with the same names as those used in the first embodiment will be denoted by the same reference numerals, and redundant explanations of these common components will be omitted.

[0032] The work schedule proposal device 1 in the second embodiment is equipped with a route calculation unit 15, as shown in Figure 5, in addition to the configuration of the first embodiment. When multiple different waiting positions are set for waiting for the train to be worked on, the route calculation unit 15 calculates a travel route that connects the multiple waiting positions for the train to be worked on in chronological order for the day assigned to the worker. There are various methods for calculating the travel route, including methods used in car navigation systems, for example, and the travel route calculation method used to calculate the travel route that connects the worker's waiting positions in chronological order is not limited here, and its explanation is omitted.

[0033] The route calculation unit 15, for example, triggered by the planning unit 13 formulating a work schedule for workers, uses the formulated work schedule and pre-assigned location information to identify waiting positions to calculate the movement routes of workers for each workday included in the work schedule.

[0034] The output unit 14 outputs, for example, work plan information representing the worker's work plan formulated by the planning unit 13, along with the travel route information calculated by the route calculation unit 15.

[0035] Other than the configuration described above, the configuration of the work schedule proposal device 1 in the second embodiment is the same as that of the first embodiment.

[0036] Since the work schedule proposal device 1 of the second embodiment has the same configuration as the first embodiment, it can achieve the same effects as the configuration of the first embodiment. Furthermore, the work schedule proposal device 1 of the second embodiment is equipped with a route calculation unit 15, which can calculate the worker's travel route and provide it to the worker, thereby increasing convenience for the worker.

[0037] <Other Embodiments> This disclosure is not limited to the first or second embodiments, and various forms of implementation are possible. For example, if an event occurs in the train's operating section that significantly increases the number of passengers compared to normal conditions, the increase in passengers will lead to an increase in garbage and dirt inside the train, thus increasing the workload for maintenance work. Taking this into consideration, the acquisition unit 12 may acquire information about scheduled events in the train's operating section during the planning period as information used to estimate the workload for maintenance work. In this case, the work plan formulation model formulates a work plan for workers, taking into account the increase in the workload for train maintenance work related to the detected event using the event information acquired by the acquisition unit 12. As a result, the work plan proposal device 1 can formulate a work plan for workers that also prepares for the increase in the workload for maintenance work caused by events in the train's operating section during the planning period.

[0038] Furthermore, although the acquisition unit 12 is provided in the first and second embodiments, the acquisition unit 12 may be omitted to reduce the processing load, for example, depending on the performance of the computer device constituting the work schedule proposal device 1. Even if the acquisition unit 12 is omitted, the work schedule proposal device 1 can still achieve the effect of suppressing variations in the workload per worker between trains due to train usage conditions.

[0039] The work plan proposal device in this disclosure may also take the configuration shown in Figure 6, for example. The work plan proposal device 60 shown in Figure 6 is, for example, a computer device and comprises a reception unit 61, a planning unit 62, and an output unit 65 as functional units realized by executing a computer program. The reception unit 61 receives planning period information representing the planning period which is the target period of the work plan to be formulated, worker information representing the workers who perform maintenance work including cleaning the train and are the target of the work plan, work constraint information representing the work constraints of the workers during the planning period, and operation information of the trains to be worked on during the planning period.

[0040] The planning unit 62 uses the received planning period information, worker information, work constraint information, operation information, and a work plan formulation model to formulate a worker work plan that includes information on the trains to which maintenance work will be assigned during the planning period. The work plan formulation model is a model that uses the received planning period information, worker information, work constraint information, and operation information to formulate a worker work plan for the planning period and the trains to which maintenance work will be assigned to the workers. Furthermore, the work plan formulation model is a model that has learned the relationship data between train usage-related information related to the amount of maintenance work on trains and actual information on the amount of maintenance work on trains. It then uses the estimated amount of maintenance work for each target train, which is calculated using the usage-related information of the target train, to formulate a worker work plan that includes information on the trains to which maintenance work will be assigned during the planning period.

[0041] The output unit 63 outputs work plan information representing the work schedule of the workers that has been formulated.

[0042] Next, an example of the operation of the work schedule proposal device 60 will be explained using Figure 7. Figure 7 is a flowchart illustrating an example of the operation of the work schedule proposal device 60. It can also be said that Figure 7 represents an example of a work schedule proposal method by the work schedule proposal device 60.

[0043] For example, the reception unit 61 receives information necessary for formulating a work plan, such as planning period information, worker information, work constraint information, and operation information (step 201). Then, the planning unit 62 uses the information received by the reception unit 61 and the work plan formulation model to formulate a work plan for workers, including information on trains to which maintenance work will be assigned during the planning period (step 202). Finally, the output unit 63 outputs the work plan information (step 203).

[0044] The work schedule proposal device 60 is configured to formulate a work schedule for workers, taking into account the estimated workload of maintenance work for each train being worked on. As such, it can formulate a work schedule for workers that can equalize the workload of workers performing maintenance work, including cleaning the inside of trains.

A planning unit formulates a work plan for the workers, including information on trains to which maintenance work is assigned during the planning period, using a work plan formulation model that formulates the work plan for the workers during the planning period and the trains to which maintenance work is assigned during the planning period, using the received planning period information, worker information, work constraint information, and operation information.

The output unit outputs temporary information representing the changed temporary work schedule. The work schedule proposal device described in Appendix 1.
