[0010] (The circumstances leading to the acquisition of the embodiments of this disclosure)

[0011] The progress management device described in Patent Document 1 focuses on the amount of work in planning and actual work. In other words, it visualizes how much of the actual work was completed compared to the planned amount of work. However, when a task involves multiple processes, it is difficult to grasp the progress of the work for each process.

[0012] The following embodiments describe a work information processing method and a work information processing device that can grasp the progress of work for each process.

[0013] (First Embodiment)

[0014] <Configuration of the work information processing device> FIG. 1 is a block diagram showing a configuration example of a warehouse operation support system 5 in the first embodiment. Note that the system configuration shown in FIG. 1 is an example, and one system or device may be divided into a plurality of components, or a plurality of systems or devices may be combined into one. Also, a plurality of the systems or devices shown in FIG. 1 may be provided. Furthermore, the processing entities shown below are examples, and a part of the functions of a certain system or device may be realized as the functions of another system or device.

[0015] The warehouse operation support system 5 includes a work management system 100, a work information processing device 200, a manager terminal 300, and a worker terminal 400. Each component constituting the warehouse operation support system 5 is configured to be communicable with each other via a network.

[0016] The work management system 100 is a system that manages and controls the logistics in the warehouse and is located above the work information processing device 200 in the configuration example shown in FIG. 1. The work management system 100 manages, for example, all aspects of warehouse operations such as the receipt and shipment of goods, storage, inventory management, picking of goods, shipping, and inventory monitoring. The work management system 100 may be referred to as a warehouse management system or a WMS (Warehouse Management System), etc.

[0017] The work information processing device 200 is an information processing device that manages and optimizes the work in the warehouse, and is located below the work management system 100 and the administrator terminal 300 in the configuration example shown in FIG. 1. The work information processing device 200 manages processes such as warehousing, shipping, picking, and packing in real time, and obtains work plan information regarding the work plan. The work information processing device 200 may generate work plan information within its own device, or may obtain work plan information from an external device. Further, the work information processing device 200 obtains work result information regarding the work results worked according to the work plan. The work information processing device 200 controls to display the work plan information and the work result information for each process included in the work. The work information processing device 200 functions as an interface of a system such as, for example, a warehouse operation management system or a WES (Warehouse Execution System). The work information processing device 200 transmits a work plan or a work instruction to the worker terminal 400. Although the case where the work information processing device 200 is an information processing device is described as an example, various functions and configurations of the work information processing device may be replaced with a cloud or the like.

[0018] The administrator terminal 300 is an information processing device such as a PC (Personal Computer) or a tablet terminal possessed by the administrator of the warehouse, and is located above the work information processing device 200 in the configuration example shown in FIG. 1. The administrator terminal 300 transmits various parameters (work plan parameters) necessary for creating a work plan, such as the work completion target time, to the work information processing device 200. Further, the administrator terminal 300 may obtain the work plan information and the work result information from the work information processing device 200 and display the same content as the display unit 15 of the work information processing device 200. Thereby, the user can confirm the work plan information and the work result information, for example, for each process, using the administrator terminal 300.

[0019] The worker terminal 400 is an information processing device, such as a tablet terminal, carried by each worker, and in the configuration example shown in Figure 1, it is located below the work information processing device 200. The worker terminal 400 transmits information such as the start and completion of work and the progress of work to the work information processing device 200 in real time. The worker terminal 400 may also acquire work plan information and work performance information from the work information processing device 200 and display the same content as the display unit 15 of the work information processing device 200. This allows the user to check the work plan information and work performance information, for example, for each process, using the worker terminal 400.

[0020] <Example of hardware configuration for work information processing device> Figure 2 is a block diagram showing an example of the hardware configuration of the work information processing device 200 according to Embodiment 1. The hardware configuration of the work information processing device 200 described herein is an example, and some parts may be omitted or other parts may be added as needed.

[0021] The work information processing device 200 comprises a control unit 11, a storage unit 12, a communication unit 13, an input unit 14, and a display unit 15. Each component is configured to communicate via an internal interface 16.

[0022] The control unit 11 may be configured using, for example, a CPU (Central Processing Unit), a GPU (Graphical Processing Unit), an MPU (Micro Processing Unit), a DSP (Digital Signal Processor), or an FPGA (Field-Programmable Gate Array). The control unit 11 implements various functions described later by, for example, referring to various databases stored in the storage unit 12 or reading programs.

[0023] The memory unit 12 is a memory unit for storing various data and programs, and may consist of volatile / non-volatile memory units such as RAM (Random Access Memory), ROM (Read Only Memory), and HDD (Hard Disk Drive). The memory unit 12 may store work plan information, work performance information, and information associated with various work processes (for example, work duration).

[0024] The communication unit 13 is an interface for communicating with external devices via a network. The communication standards supported by the communication unit 13 are not particularly limited and can be wired or wireless. Furthermore, it may support multiple communication standards. Therefore, the network may be composed of a combination of networks using multiple communication standards.

[0025] The input unit 14 accepts, for example, operations and instructions from the user. The input unit 14 may consist of a mouse, keyboard, touch panel display, microphone, etc. Users include those responsible for work planning or management, those responsible for managing progress or management, etc.

[0026] <Example of functional configuration of a work information processing device> Next, an example of the functional configuration of the work information processing device 200 will be described. Each part shown in Figure 1 may be realized, for example, by the control unit 11 reading a program stored in the storage unit 12, or by providing dedicated hardware.

[0027] Note that the configuration shown in Figure 1 is just one example; the parts shown in Figure 1 may be combined into a single configuration, or they may be further divided into more detailed configurations. Also, the links and arrows in Figure 1 show an example of data transmission and reception, but this connection configuration is not the only one that may be used; other connections and linkages may also be used.

[0028] The control unit 11 is composed of a work information processing unit 21 and a work performance storage unit 22.

[0029] The work information processing unit 21 creates work plan information based on work instructions (orders) obtained from the work management system 100 and work plan parameters obtained from the administrator terminal 300. The work information processing unit 21 outputs work instructions to each worker based on the created work plan information to each worker terminal 400.

[0030] The work performance storage unit 22 collects and stores work performance information for each worker based on work progress, such as work start notifications and work completion notifications obtained from each worker terminal 400. The work performance storage unit 22 outputs the collected or stored work performance information for each worker to the work information processing unit 21.

[0031] The work information processing unit 21 acquires the current time and calculates the delay time for the process and the entire work based on the current time, the current work plan information, and the work performance information of each worker acquired from the work performance storage unit 22. The work information processing unit 21 also calculates the additional work time, which will be described later, based on the delay time.

[0032] Furthermore, after the commencement of work based on the aforementioned work plan information, the work information processing unit 21 may reacquire work instructions from the work management system 100 and reacquire work plan parameters from the administrator terminal 300. Then, the work information processing unit 21 recreates (or "modifies" in a broad sense, hereinafter the same) the work plan information based on the reacquired work instructions and work plan parameters, as well as the work performance of each worker (or robot not shown, hereinafter the same) obtained from the work performance storage unit 22 and the calculated delay time of each worker's work. The work information processing unit 21 outputs work instructions to each worker based on the recreated work plan to each worker terminal 400 (or robot or device that controls the robot, hereinafter the same).

[0033] <Details of input information> Next, we will explain the input information (specifically, work plan parameters) that is entered from the administrator terminal 300 to the control unit 11.

[0034] The control unit 11 inputs information, for example, by importing a configuration file used for creating a work plan. The configuration file contains work plan parameters from the administrator terminal 300.

[0035] The input information serves as the source information for generating the work plan. This input information includes worker shift information, available work information, work plan creation rule information, target work completion time information, and detailed work information.

[0036] Worker shift information refers to information about workers' shifts and includes attendance information. Worker shift information may include the worker's scheduled start time, scheduled end time, break times, etc. Worker shift information may also include the workers available to work on that day and their working hours.

[0037] Worker-capable work information refers to information about the tasks that a worker can perform. Here, "worker" may include not only humans but also robots. Worker-capable work information may include information about the work processes that each worker can perform. Worker-capable work information may also include information about the worker's skills (for example, information such as being able to pick but not being able to pack).

[0038] Work planning rules are information about the rules that define how to create a work plan. Work planning rules may include, for example, the following first, second, and third rules: The first rule is to complete all work as quickly as possible. The second rule is to synchronize the estimated completion times of all work with the target completion times, while also synchronizing the processes. The third rule is to perform the work with the minimum number of people while aligning the estimated completion times of all work with the target completion times.

[0039] The target completion time information pertains to the target time for completing a task. For example, the time at which a delivery truck departs for its destination from a logistics warehouse is set as the target completion time. The target completion time information may also be entered by the user, for example, via the input unit 14.

[0040] Task details are information about the specific steps involved in a task. For example, task details include information such as the standard time required for each step (i.e., the total work time).

[0041] A "process" refers to a collection of tasks of the same category within the smallest unit of work (determined by the user). However, tasks within the same category do not have to be the same. The smallest unit of work may be determined by the user. For example, in the case of pick-and-place, the smallest unit of work is picking and placing product A, and the process is performing pick-and-place of product A 10 times. For example, in the case of packaging, the smallest unit of work is assembling the box, packing the product into the box, and sealing the box, and the process is the entirety of these three tasks. Since the work units may be set by the user, the process in Example 2 may be set as the smallest unit of work.

[0042] <Overview of warehouse operations support system processing> Next, we will explain the processing overview of the warehouse operations support system 5.

[0043] The control unit 11 acquires input information from the administrator terminal 300. The control unit 11 acquires work instruction information related to work instructions from the work management system 100. Based on the control instruction information and the input information, the control unit 11 generates work plan information for carrying out the instructed work. The work plan information includes process plan information, which is information about the plan corresponding to each process included in the work. In other words, the process plan information is work plan information divided by process. The control unit 11 may also acquire work plan information generated by an external device via the communication unit 13. Processes may include, for example, picking processes, packing processes, shipping processes, breaks, etc. The work plan information includes, for example, process identification information to identify the process, worker identification information to identify the worker who will carry out the process, and the scheduled time for carrying out the process. The scheduled time may include the scheduled start time and the scheduled completion time.

[0044] The control unit 11 acquires work start information indicating that a worker has started work (e.g., a process). For example, the control unit 11 acquires a work start notification from the worker terminal 400 as work start information, informing that the worker has started work. The control unit 11 may also recognize that work (e.g., a process) has started by acquiring code reading information, for example, when a code (e.g., a two-dimensional code, a barcode) has been read by a code reader. The work start information includes the worker who started the work, the time the work started, identification information of the started work, etc.

[0045] The control unit 11 acquires work completion information indicating that a worker has completed a task (e.g., a process). For example, the control unit 11 acquires a work completion notification from the worker terminal 400 as work completion information, informing the worker that the work has been completed. The control unit 11 may also recognize that a task (e.g., a process) has been completed by acquiring code reading information, for example, when a code (e.g., a two-dimensional code, a barcode) has been read by a code reader. The work completion information includes the worker who completed the task, the start time of the completed task, identification information of the completed task, etc.

[0046] The control unit 11 generates work performance information based on work start information and work completion information, and stores it in the work performance storage unit 22. The generation of work performance information is an example of acquiring work performance information. The work performance information includes each process performance information, which is information on the performance of each process included in the work. In other words, process performance information is work performance information divided by process. For example, the work performance information includes process identification information to identify the process, worker identification information to identify the worker who performed the process, and the actual time the process was performed. The actual time may include the start time and the completion time of the actual time performed.

[0047] The control unit 11 displays work plan information and work performance information on the display unit 15 for each process. In other words, for each process, it displays process plan information and process performance information corresponding to that process. This allows the user to compare and verify the work plan information and work performance information for each process. Furthermore, by comparing the process plan information and process performance information, the user can notice even if a process different from the one planned in the work plan information has been performed. This is because the difference between the process related to the displayed process plan information (e.g., picking 1) and the process related to the displayed process performance information (e.g., picking 2) becomes visible.

[0048] Furthermore, the control unit 11 may display work plan information and work performance information for each process, as well as for each worker.

[0049] The control unit 11 may display the work plan information with more emphasis than the work performance information. In this case, the control unit 11 may display the work performance information in gray. This makes it easier for the user to check the planned processes to be implemented in the future rather than the processes that have already been implemented in the past.

[0050] When the control unit 11 acquires completion information for a predetermined process included in the work plan information, it terminates the display of the process plan information for that process and begins displaying the process actual information for that process. In other words, when a planned process is completed, the control unit 11 shifts from displaying the plan to displaying the actual results.

[0051] If the control unit 11 determines that a predetermined process included in the work plan information is not completed within its scheduled time, it does not terminate the display of the process plan information for that process. In other words, the control unit 11 leaves this process plan information as is.

[0052] The control unit 11 may highlight the process plan information for a predetermined process included in the work plan information if that process has not been completed by the scheduled time. This makes it easier for the user to recognize processes that were planned but have not been completed.

[0053] Furthermore, the control unit 11 may update the work plan information periodically or irregularly. The control unit 11 may update the work plan information automatically or manually (for example, by detecting a button press). The control unit 11 may update the display of the work plan information periodically or irregularly. The control unit 11 may update the display of the work plan information automatically or manually (for example, by detecting a button press). The control unit 11 may update the work performance information periodically or irregularly. The control unit 11 may update the work performance information automatically or manually (for example, by detecting a button press). The control unit 11 may update the display of the work performance information periodically or irregularly. The control unit 11 may update the display of the work performance information automatically or manually (for example, by detecting a button press).

[0054] When the control unit 11 automatically updates the work plan information, information about the update schedule, including the update interval, may be stored in the storage unit 12. When the control unit 11 updates the work plan information, it also updates the display of the work plan information. When the control unit 11 automatically updates the work performance information, information about the update schedule, including the update interval, may be stored in the storage unit 12. When the control unit 11 updates the work performance information, it also updates the display of the work performance information.

[0055] The update frequency of work performance information may be higher than that of work plan information. The update frequency of the display of work performance information may also be higher than that of the display of work plan information. In this case, since work performance information is updated and reflected in the display frequently, users can check the latest performance.

[0056] Furthermore, the update frequency of work plan information may be higher than the update frequency of work performance information. The update frequency of the display of work plan information may also be higher than the update frequency of the display of work performance information. For example, if there are many urgent orders or if there are many plan revisions due to work delays, the update frequency of work plan information may consequently be higher than the update frequency of work performance information.

[0057] If the control unit 11 finds that a predetermined process planned in the work plan information has not been completed within the scheduled time for that process (i.e., by the target completion time), it recreates (i.e., updates) the work plan information, including the process plan information for this process. In other words, in the new work plan information, the control unit 11 schedules this process for a later time than the current time, meaning the plan to perform the process in the future is shifted.

[0058] Next, we will explain specific examples of how to display work-related information.

[0059] <Example of a work information display screen> Figure 3 shows the first example of a work information display screen (work information display screen G1).

[0060] The work information display screen G1 displays work plan information I1 and work performance information I2 for each worker for each process. Work plan information I1 includes one or more process plan information I10. Work performance information I2 includes one or more process performance information I20. The control unit 11 generates a process plan box B1 based on the worker and scheduled time for each process, and displays the process plan box B1 in the plan display area R1 in the schedule area SR at the time position corresponding to the scheduled time. The process plan box B1 is an example of a visualization of the process plan information I10.

[0061] When each process is initiated according to the work plan information I1, no processes are completed. Therefore, at the start of work, the work performance information I2 has not yet been generated, and neither the work performance information I2 nor the process performance information I20 is displayed. As time passes, each process planned in the work plan information is gradually completed. When the control unit 11 acquires process completion information after a predetermined process is completed, it generates process performance information for that process and stores the work performance information I2, including the process performance information I20, in the work performance storage unit 22. The control unit 11 generates a process performance box B2 based on the worker and the actual execution time of the process, and displays the process performance box B2 in the performance display area R2 in the schedule area SR at the time position corresponding to the actual execution time. On the other hand, when the control unit 11 acquires process completion information for a predetermined process, it deletes the process plan box B1 for the predetermined process from the plan display area R1 and hides it. The process performance box B2 is an example of visualizing the process performance information I20.

[0062] On the work information display screen G1, for each worker, work plan information I1 is displayed in the "Plan" row, i.e., the plan display area R1, and work performance information I2 is displayed in the "Actual" row, i.e., the actual performance display area R2. In other words, for each worker, work plan information I1 and work performance information I2 are displayed in two separate rows.

[0063] For example, in the display area for worker ID: 123456, the work plan information I1 includes an inspection process, and the inspection process plan box B1 is displayed. Upon completion of the inspection process, the inspection process actuals box B2 is added and displayed in the worker's actuals display area R2. The process actuals box B2 is displayed in a less conspicuous manner than the process plan box B1, for example, by being grayed out. In Figure 3, the grayed-out display is indicated by the dashed outline of the process actuals box B2. By graying out the process actuals box B2, the control unit 11 makes the information related to the plan easier to see than the actuals. Therefore, the user can clearly distinguish between the plan and the actuals, and it becomes easier to recognize the plan.

[0064] Furthermore, in the worker display field for worker ID: 908989, the work plan information I1 included picking process 1 (simply "Picking 1" in Figure 3) and picking process 2 (simply "Picking 2" in Figure 3), and the respective process plan boxes B1 were displayed. Let's assume that this worker performed picking process 2 instead of picking process 1 at the scheduled time for picking process 1, which was included in the work plan information I1.

[0065] In this case, the control unit 11 adds the process performance box B2 for picking process 2 to the performance display area R2, that is, it starts displaying the process performance box B2 for picking process 2.

[0066] On the other hand, in this case, the control unit 11 deletes the process plan box B1 for picking process 2 from the planning display area R1, that is, it terminates the display of the process plan box B1 for picking process 2. Also, if picking process 1 is not completed even after the scheduled time for execution of picking process 1, that is, if it is not completed by the scheduled completion time for execution, the control unit 11 does not delete the process plan box B1 for picking process 1, that is, it continues to display the process plan box B1 for picking process 1. In this case, the control unit 11 may highlight the process plan box B1 for picking process 1 (see area A6). For example, the control unit 11 may display the process plan box B1 for picking process 1 in a different display manner (e.g., a different color) than the other scheduled process plan boxes B1, so that it stands out more than the other scheduled process plan boxes B1.

[0067] The control unit 11 displays the work information display screen G1 on the display device 150. In addition to the information described above, the work information display screen G1 can display various other information in its respective areas. Note that the areas on the work information display screen G1 are not limited to the positions shown in Figure 1, but may be displayed in other positions as well.

[0068] Area A0 is the area that specifies from what perspective (display perspective) the work information will be displayed. Display perspectives include, for example, by worker, by process, etc. Work information includes at least one of work plan information and work performance information. The control unit 11 may specify the display perspective via the input unit 14. In the work information display screen G1, "by worker" is specified as the display perspective.

[0069] Area A3 is a time zone indication area that specifies which time period of work information to display. The control unit 11 may specify the time period to be displayed (for example, 8:00 to 20:00) via the input unit 14.

[0070] The Schedule Area (SR) is an area that displays process plan information and process performance information in chronological order for a predetermined period (e.g., one day), and is an area that displays work plan information and work performance information.

[0071] Area A7 is an area that displays detailed process information for a specified process. The detailed process information includes identification information for the specified process (e.g., picking 1), the area where the process is performed (e.g., area A), information about the delivery destination of the goods used in the process, etc. The control unit 11 may, for example, form area A7 and display the detailed process information for a process when a process is specified by clicking or hovering the mouse, which is the input unit 14, over the process planning box B1.

[0072] Area A8 is an area for displaying group identification information that identifies groups of work divided according to predetermined criteria. As shown in Figure 4, which will be described later, the group display area can display group identification information in a list, for example. For example, when multiple trucks transporting goods in a logistics warehouse are coming and going, groups of work to be loaded onto truck A, groups of work to be loaded onto truck B, and so on can be easily created.

[0073] Area A9 displays information such as the predicted completion time, target completion time, delay time, and additional required work time. The predicted completion time is the time when all tasks planned in the work plan are expected to be completed. The target completion time is the target time for all tasks planned in the work plan to be completed. The delay time shows the difference between the predicted completion time and the target completion time, indicating the time that will be delayed from the target completion time. The additional required work time is the time required to eliminate the delay time. Note that the target completion time, delay time, and additional required work time will not display specific values ​​until a group is specified.

[0074] The control unit 11 derives the predicted completion time and the target completion time based on the input information. Based on the predicted completion time and the target completion time, the control unit 11 calculates the delay time, specifically based on how much the predicted completion time is delayed relative to the target completion time. Based on the delay time, the control unit 11 calculates the additional required work time. For example, the control unit 11 may set the additional required work time to be the same as the delay time. The control unit 11 may also calculate the additional required work time based on the delay time and the work (process) where the delay is expected to occur. The control unit 11 displays the derived predicted completion time, target completion time, delay time, and additional required work time.

[0075] Furthermore, the control unit 11 may derive (for example, calculate) the number of additional workers to be added based on the additional work time required. By adding the derived number of workers, the control unit 11 can eliminate the delay time and meet the target time for work completion.

[0076] Area A10 is an area that displays information such as the plan creation status and the update date and time (work plan update date and time) when the work plan information was updated. The plan creation status includes "Success" indicating that the plan was created successfully, "Insufficient work time" indicating that the workload is large and the work cannot be completed with the current work time, "No work to create a plan for" indicating that there is no work for which a plan should be created, and "Invalid work plan setting" indicating a setting when there is an error in the work plan information.

[0077] The control unit 11 may, for example, derive the above-mentioned plan creation state based on the input information. The control unit 11 may, for example, store the date and time when the work plan was created or acquired in the storage unit 12, and derive this date and time as the work plan update date and time. The control unit 11 displays the information of the plan creation state and the work plan update date and time.

[0078] Area A11 is an area that displays information indicating the update interval for updating the work plan. This update interval may include, for example, every hour, or updating as needed.

[0079] Area A12 is the area where the work plan button is displayed. The work plan button is a button that instructs the creation or updating of work plan information.

[0080] When the control unit 11 receives input to the plan creation button via the input unit 14, it may generate or update work plan information. Furthermore, the control unit 11 may generate or update work plan information based on the input information each time it acquires input information. When updating work plan information, if a predetermined process included in the work plan information before the update has not been completed within the scheduled time, the control unit 11 may update (recreate) the work plan information to include this process.

[0081] For example, as shown in Figure 3, in the worker display field for worker ID: 908989, it is assumed that picking process 1 has not been completed by the scheduled end time (e.g., 10:00) of the scheduled execution time for picking process 1 included in the work plan information. In this case, the control unit 11 may recreate the work plan information including picking process 1, using a time later than the above scheduled end time (e.g., 10:00) for picking process 1 as the scheduled execution time.

[0082] Area A13 is an area that displays a plan display update button for updating the display of a created or updated work plan. The update target here may be the entirety or a part of the work information display screen G1. Note that operating the plan display update button does not update the work plan information. The control unit 11 may also automatically update the work plan display, for example, at predetermined intervals, even when no input is made to the plan display update button.

[0083] Area A14 is an area that displays a download button for downloading work progress data. The work progress data may include at least one of work plan information and work performance information. The control unit 11 downloads the work progress data by receiving input to the download button via the input unit 14.

[0084] In Figure 3, the process plan box B1 and process performance box B2 for each process included in the work are shown in essentially the same display format, but this is not limited to this. The control unit 11 may display the process plan box B1 with a different display format (e.g., color) for each process. The control unit 11 may also display the process performance box B2 with a different display format (e.g., color) for each process.

[0085] Figure 4 shows a second example of the work information display screen (work information display screen G2). In Figure 4, explanations of content similar to that in Figure 3 are omitted or simplified.

[0086] In area A8 of Figure 4, a list of group identification information for filtering work plan information I1 is displayed. The input unit 14 receives input specifying the desired group identification information from the list of displayed group identification information. The control unit 11 may specify the desired group according to the received input and filter the work plan information I1 related to the work belonging to that group to be displayed.

[0087] Figure 5 shows a third example of the work information display screen (work information display screen G3). In Figure 5, explanations of content similar to that in Figure 3 or Figure 4 are omitted or simplified.

[0088] In area A8 of Figure 5, the group identification information for the specified desired group is displayed.

[0089] Area A9 in Figure 5 displays information related to the work plan information I1 belonging to the designated group, including the predicted completion time, target completion time, delay time, and additional required work time. The predicted completion time here is the time when all tasks within the group planned in the work plan are expected to be completed. For example, it is the time when the last task in that group is expected to finish. The target completion time is the time when all tasks within the group planned in the work plan are expected to be completed. For example, the target completion time is the time when the delivery truck departs from the logistics warehouse, and this is the time by which the work should be completed. The delay time and additional required work time are as described above.

[0090] In the schedule area SR of Figure 5, the process plan information for a specified group may be displayed in a more prominent manner than the process plan information for groups other than the specified group, i.e., using a different display method (e.g., a different color). In Figure 5, the grayed-out display is indicated by the dashed outline of the process plan box B1.

[0091] Furthermore, the control unit 11 displays a target time line L1 in the schedule area SR at the time position corresponding to the target work completion time (e.g., 4:42 PM). The target time indicated by the target time line L1 is the same time as the target work completion time displayed in area A9. The control unit 11 also displays a predicted completion time line L2 in the schedule area SR at the time position corresponding to the predicted completion time (e.g., 4:00 PM). The predicted completion time indicated by the predicted completion time line L2 is the same time as the predicted completion time displayed in area A9. The control unit 11 also displays a current time line L3 in the schedule area SR at the time position corresponding to the current time (e.g., 10:00 AM). This allows the user to easily recognize a reference time.

[0092] In this way, the work information processing device 200 can provide the user with work progress information, including work plans and actual work results for a desired group. By checking the work information display screen G3, the user can confirm, for example, whether the entire operation, including the loading process, will be completed before truck A departs at 4:42 PM (an example of a target time for work completion).

[0093] Figure 6 shows the fourth example of the work information display screen (work information display screen G4). In Figure 6, the explanations of the same content as in Figures 3 to 5 described above are omitted or simplified.

[0094] The aforementioned work information display screens G1 to G3 used the worker as the key to categorize by process and display work plan information I1 and work performance information I2 for each worker. In contrast, work information display screen G4 uses the process as the key to display work plan information I1 and work performance information I2. The process plan information I10 in work plan information I1 is visualized by process plan box B11, which shows the number of workers for each process and time period. The process performance information I20 in work performance information I2 is visualized by process performance box B12, which shows the number of workers for each process and time period.

[0095] The control unit 11 generates work plan information based on the input information. The work plan information includes information indicating which worker will perform which process at which time. The work plan information may include information on the number of workers for each time period during which the process is performed. The control unit 11 may also derive (e.g., calculate) the number of workers for each time period during which the process is performed, based on the work plan information. Furthermore, the process performance information obtained upon completion of the process may include information indicating which worker performed which process at which time. The work performance information may include information on the number of workers for each time period during which the process was performed, based on the work performance information. The control unit 11 may also derive (e.g., calculate) the number of workers for each time period during which the process was performed, based on the work performance information.

[0096] The control unit 11 generates a process plan box B11 based on the number of workers for each time period for each process, and displays the process plan box B11 at the time position corresponding to this time period in the plan display area R1 of the schedule area SR.

[0097] When each process is initiated according to the work plan information I1, no processes are completed. Therefore, at the start of work, the work performance information I2 has not yet been generated, and neither the work performance information I2 nor the process performance information I20 (e.g., process performance box B12) is displayed. As time passes, each process planned in the work plan information is gradually completed. When the control unit 11 acquires process completion information after a predetermined process is completed, it generates process performance information for that process and stores the work performance information, including the process performance information, in the work performance storage unit 22. The process performance information includes information such as the worker who performed the process, the area where the process was performed, and the actual time the process was performed. Based on each worker and the actual time of each process, the control unit 11 generates a process performance box B12 and displays it in the performance display area R2 in the schedule area SR at the time position corresponding to the actual time. On the other hand, when the control unit 11 acquires process completion information for a predetermined process, it deletes the process plan box B1 for the predetermined time period from the plan display area R1 and hides it.

[0098] Therefore, the work information processing device 200 can check the number of workers for each time period of each process by comparing the work plan with the actual work results. For example, by comparing the plan with the actual results, the work information processing device 200 can easily determine the number of people needed if a similar process is to be performed again.

[0099] Furthermore, the control unit 11 may acquire the current time and, if a predetermined process included in the work plan information is not completed within the scheduled time, highlight the corresponding process plan box B11 (an example of a process plan box). Here, the control unit 11 may display the process plan box B11 of the process that was not completed within the scheduled time in a different display manner (for example, a different color) than the process plan box B11 of other scheduled processes, making it more conspicuous than the process plan box B11 of other scheduled processes.

[0100] For example, in the display area for picking process A, the work plan information shows that 3 workers are planned for the time period from 8:30 to 9:10, and process plan box B11 was displayed during this time period. When picking process A is completed, process actuals box B12 for picking process A is added and displayed in the actuals display area R2 for this time period. Process actuals box B12 includes and displays the actual number of workers. Process actuals box B12 is displayed in a less conspicuous manner than process plan box B11, for example, by being grayed out. In Figure 6, the grayed-out display is indicated by the dashed outline of process actuals box B12. By graying out process actuals box B2, the control unit 11 makes the information related to the plan easier to see than the actuals. Therefore, the user can clearly distinguish between the plan and the actuals and recognize the plan more easily.

[0101] Furthermore, in the display section for the inspection process, the work plan information includes a plan for inspection to be carried out by five or fewer workers during the time period of 8:30 to 9:40, and the process plan box B11 was displayed at this time. However, the scheduled inspection process was not completed during this time period.

[0102] In this case, the control unit 11 does not delete the process plan box B11 for this time period, that is, it continues to display the "~5 people" process plan box B11. In this case, the control unit 11 may highlight the "~5 people" process plan box B11 (see area D3). For example, the control unit 11 may display the "~5 people" process plan box B11 in a different display manner (e.g., a different color) than the process plan box B11 of other planned processes, making it more conspicuous than the process plan box B11 of other planned processes. The control unit 11 may also choose not to perform such highlighting.

[0103] Furthermore, the control unit 11 may consider the detailed processes, which are subdivisions of the process described later, and decide whether or not to delete the process plan box B11 from the work plan information depending on whether or not the detailed processes have been completed.

[0104] Furthermore, the control unit 11 may display the total number of workers in each process hourly based on the work plan information. In this case, the user can, for example, grasp the total number of workers performing each process in a logistics warehouse, making progress management easier.

[0105] The control unit 11 displays the work information display screen G4 on the display unit 15. In addition to the information described above, the work information display screen G4 can display various other information in its respective areas. Note that the areas on the work information display screen G4 are not limited to the positions shown in Figure 6, but may be displayed in other positions as well.

[0106] Area A0 is the area where the display viewpoint is specified. In the work information display screen G4, process-specific is specified as the display viewpoint.

[0107] Area D1 is an area that displays process identification information (e.g., process name) that identifies a process. Processes include receiving, inspection, picking, packing, etc. Processes may be the same process or they may be separated into individual processes.

[0108] Area D2 is the area that displays the area where the process is carried out.

[0109] Furthermore, process plan box B11 and process performance box B12 may indicate a fixed number of workers who are carrying out or have carried out a process, or they may indicate the maximum number. For example, "3 people" may indicate that there are 3 workers, and "~3 people" may indicate that there are 3 or fewer workers.

[0110] Figure 7 illustrates the maximum number of people in a given time period. In Figure 7, workers 1 to 3 perform the same process during the given time period. Since the maximum number of people performing the process simultaneously during the given time period is 3, the process plan box B11 and process actual box B12 are displayed as "~3 people". In other words, this indicates that the process was performed or is being performed by 3 people or less.

[0111] <Example of display regarding detailed process> Next, we will explain how to display work information when a process includes multiple detailed steps.

[0112] Figure 8 is a diagram illustrating the detailed steps included in the process. In Figure 8, picking 1 as a process includes eight detailed steps. A detailed step is the smallest unit of work as described above.

[0113] Figure 8 is a diagram illustrating the planned information, actual information, and process box display for picking 1 at each time point. In Figure 8, the displays for times t1 to t4 are shown in chronological order.

[0114] At time t1, the work plan information, including detailed processes 1-8, is displayed as process plan box B1 "Picking 1". This process plan box B1 has a length (time duration) corresponding to the planned execution time of detailed processes 1-8. Note that detailed processes 1-8 each have the same time duration, but are not limited to this. The planned execution time durations for each detailed process may be different. At this stage, none of detailed processes 1-8 have been executed, and process actuals box B2 does not exist.

[0115] At time t2, detailed process 1 is performed. In this case, detailed process 1 is excluded from the work plan information and included in the work performance information, and the process plan box B1 and process performance box B2 are displayed. Therefore, process plan box B1 "Picking 1" is displayed with a time length corresponding to the scheduled time of detailed processes 2 to 8. Also, process performance box B2 is displayed with a time length corresponding to the actual time of detailed process 1.

[0116] At time t3, detailed processes 3 and 4 are performed. In this case, detailed processes 3 and 4 are excluded from the work plan information and included in the work performance information, and the process plan box B1 and process performance box B2 are displayed. Therefore, the process plan box B1 "Picking 1" has a portion displayed at the time position where detailed process 2 is scheduled to be performed, with a time length corresponding to the scheduled time of detailed process 2, and a portion displayed at the time positions where detailed processes 5 to 8 are scheduled to be performed, with a time length corresponding to the scheduled time of detailed processes 5 to 8. In addition, the process performance box B2 is displayed at the time positions where detailed processes 1, 3, and 4 were performed, with a time length corresponding to the actual time of detailed processes 1, 3, and 4. Note that in Figure 8, detailed processes 3 and 4 are performed immediately after detailed process 1 is performed, so the process performance box B2 corresponding to detailed processes 1, 3, and 4 is not divided into multiple parts but is displayed as a single continuous process performance box B2.

[0117] Furthermore, if the display of process plan box B1 is divided into multiple parts (for example, two) as described above, the process plan box B1 may be displayed by connecting the two adjacent parts, provided that the time interval between the two adjacent parts (i.e., the length of time for the completed and deleted detailed process) is within a predetermined time. In this case, the work information processing device 200 can prevent the display of process plan box B1 from becoming fragmented and making it difficult to recognize the planned process by connecting the two adjacent parts.

[0118] At time t4, detailed processes 2 and 5 are performed. In this case, detailed processes 2 and 5 are excluded from the work plan information and included in the work performance information, and the process plan box B1 and process performance box B2 are displayed. Therefore, process plan box B1 "Picking 1" is displayed at the time position where detailed processes 6 to 8 are scheduled to be performed, with a time length corresponding to the scheduled time of detailed processes 6 to 8. Similarly, process performance box B2 "Picking 1" is displayed at the time position where detailed processes 1 to 5 were performed, with a time length corresponding to the actual time of detailed processes 1 to 5.

[0119] Thus, as time passes, the length of the process plan box B1 decreases, and the length of the process progress box B2 increases. This is because the detailed processes included in the work plan are carried out in order. Therefore, it is possible to update the work plan information and work progress information at a finer unit than each process (i.e., at the unit of the detailed process), and update the display of the process plan box B1 and process progress box B2. As a result, users can intuitively grasp the progress of the work, taking into account the detailed processes.

[0120] Figure 8 illustrates how the detailed process is taken into account and applied to the process plan box B1 and process performance box B2 in the work information display screens G1 to G3, but it is not limited to this. The control unit 11 may also take the detailed process into account and apply it to the process plan box B11 and process performance box B12 in the work information display screen G4.

[0121] As described above, the work information processing device 200 of this embodiment displays work performance information and work plan information for each process on the display unit 15 of the work information processing device 200, the administrator terminal 300, or the worker terminal 400. Therefore, a user who checks the display on the work information processing device 200, the administrator terminal 300, or the worker terminal 400 can easily grasp the progress of the work for each process. Furthermore, by displaying the work plan information more prominently than the work performance information, the user can easily grasp the work plan and also grasp the completed work based on the work performance. In addition, even if a worker changes the order of the work plan, if the work is not completed within the scheduled time for that process in the work plan, the process plan box B1 for that process is highlighted, making it easy to understand that the plan and the actual results are different.

[0122] In this embodiment, the control unit 11 primarily displays work plan information and work performance information on the display unit 15 of the work information processing device 200 for each process, but this is not limited to this. The control unit 11 may transmit the work plan information and work performance information to an external display device via the communication unit 13, and the external display device may display the work plan information and work performance information for each process. The external display device may include, for example, an administrator terminal 300 or a worker terminal 400.

[0123] (Summary of the embodiment) Based on the above, this disclosure contains at least the following information. The components and other elements in parentheses are examples of those corresponding to the embodiments described above, but are not limited to these.
