DETAILED DESCRIPTION OF THE INVENTION

[0011] 1 shows an example of the overall configuration of a warehouse-related work analysis system according to this embodiment. The warehouse-related work analysis system according to this embodiment performs an analysis (work analysis) of the work performed by workers in a warehouse WH, and displays a screen that visualizes the analysis results on a terminal such as the warehouse terminal 300.

[0012] The goods (products) shipped by the sender arrive at Warehouse WH. The goods received are managed as inventory in Warehouse WH. The goods stored in Warehouse WH are then shipped to the designated delivery destination.

[0013] Warehouse WH is provided with, for example, a receiving department DP1, an inventory management department DP2, and a shipping department DP3. Receiving department DP1 is a department that handles the receiving of goods. Inventory management department DP2 is a department that handles the inventory management of received goods. Shipping department DP3 is a department that handles the shipping of goods that have been managed as inventory.

[0014] Each of the receiving department DP1, the inventory control department DP2, and the shipping department DP3 is provided with one or more devices 100 that operate in response to predetermined tasks. The devices 100 may include, for example, beacons, DPSs, DASs, handheld terminals, code readers, other IoT dynamic analysis systems, cameras, etc.

[0015] The device 100 is communicably connected to a warehouse management system 400 via a network NW. The device 100 is also communicably connected to a work analysis apparatus 500 via the network NW.

[0016] The warehouse WH is also provided with a warehouse terminal 300. The warehouse terminal 300 is a terminal used by a user as a warehouse manager. The warehouse terminal 300 is communicably connected to the warehouse management system 400, the work analysis device 500, etc. via a network NW. The warehouse terminal 300 and the device 100 may be communicably connected to each other via the network NW or a local area network (LAN) within the warehouse WH. In this case, the LAN may be wired or wireless. The device 100 and the warehouse terminal 300 may also be connected to the network NW via a router corresponding to the LAN within the warehouse. The warehouse terminal 300 may be, for example, a personal computer, a tablet terminal, a smartphone, etc. The warehouse terminal 300 may also be used outside the warehouse WH.

[0017] The warehouse management system 400 is also called a WMS (Warehouse Management System), and is a system that centrally manages each process from receiving goods to shipping goods in the warehouse WH. The warehouse management system 400 stores information transmitted from the devices 100 operating in the warehouse WH as warehouse management information in the warehouse management information storage unit 401. The warehouse management system 400 performs management in the warehouse WH based on the warehouse management information stored in the warehouse management information storage unit 401.

[0018] The work analysis device 500 performs analysis (work analysis) of the work (movement) of workers in the warehouse WH. The work analysis device 500 performs work analysis using worker behavior history information in addition to warehouse management information stored in the warehouse management information storage unit 401. The devices 100 include devices (worker-related devices) that are used by workers after the workers register as users. Each worker-related device transmits predetermined information obtained in response to actions performed by the user to the work analysis apparatus 500. The format of the information transmitted by the worker-related device is not particularly limited, and may be, for example, a CSV format. Note that the worker-related device may be, for example, a terminal such as a smartphone that has a predetermined application installed and is carried by each worker. Such a worker-related device may transmit information including, for example, a worker ID that identifies the corresponding worker and a location obtained by positioning. Note that the worker-related device may also transmit predetermined information to a warehouse management system. The work analysis apparatus 500 stores the information transmitted from the worker device as action history information indicating the history of the worker's actions. The work analysis device 500 performs work analysis using warehouse management information acquired from the warehouse management information storage unit 401 via communication and action history information stored therein.

[0019] The work analysis device 500 displays a work analysis screen showing the results of the work analysis on the warehouse terminal 300. The work analysis device 500 may, for example, function as a web server that provides a work analysis website. The web server in the work analysis device 500 displays the work analysis screen in response to access from the warehouse terminal 300 to the work analysis website. The work analysis here includes visualizing work performance in a predetermined manner and presenting it on a work analysis screen. It also includes presenting the results of statistically processing work performance on the work analysis screen. It also includes the work analysis device 500 simulating a predetermined work item using warehouse management information and its own stored behavioral history information, and presenting the simulation results on the work analysis screen.

[0020] FIG. 2 shows an example of the contents of warehouse management information and behavior history information obtained for each area in the warehouse WH. In the figure, the work areas within the warehouse WH are shown as a receiving area, a receiving inspection area, an inventory area, a picking area, a sorting area, a distribution processing area, a shipping inspection area, and a shipping area. The receiving area is an area where work related to receiving goods is carried out. The receiving inspection area is an area where inspection work is carried out on received goods.

[0024] In the picking area, picking work performance information is obtained as warehouse management information, and card reader information and DPS information are obtained as behavior history information. In this case, the work performance information is information about the picking work process, and includes worker information about the worker who performed the picking work, the time the item was picked, and item information about the item that was picked. In this case, the card reader information includes worker information whose worker card was read by device 100 as a card reader, the time the worker card was read, and location information indicating that the location where the worker identification card was read is a picking area. The DPS information is information output from a DPS (Digital Picking System) used by a worker when picking. The DPS information includes worker information about the user, the time the picking was performed, and item information about the item to be picked.

[0025] In the sorting area, sorting work performance information is obtained as warehouse management information, and card reader information and DAS information are obtained as behavior history information. In this case, the work performance information is information relating to the process of the sorting work, and includes worker information of the worker who performed the sorting work, the time when the items were sorted, and item information of the sorted items. In this case, the card reader information includes worker information whose worker card was read by device 100 as a card reader, the time when the worker card was read, and location information indicating that the location where the worker identification card was read is the sorting area. The DAS information is information output from the DAS (Digital Assort System) used by the worker when picking. The DAS information includes worker information about the user, the time when the sorting work was performed, and item information about the items to be sorted.

[0026] In the distribution processing area, it is shown that distribution processing work performance information can be obtained as warehouse management information, and card reader information can be obtained as behavior history information. In this case, the work performance information is information relating to the distribution processing process, and includes the time when the distribution processing of the goods was carried out and the goods information of the goods that were distributed processed. In this case, the card reader information includes worker information whose worker card was read by device 100 as a card reader, the time the worker card was read, and location information indicating that the location where the worker identification card was read is a distribution processing area.

[0027] In the shipping inspection area, shipping inspection performance information can be obtained as warehouse management information, and card reader information and handy terminal information can be obtained as behavior history information. The shipping inspection performance information is information about the shipping inspection process, and includes the time when the shipped item was inspected and item information about the shipped item. In this case, the card reader information includes worker information whose worker card was read by device 100 as a card reader, the time when the worker card was read, and location information indicating that the location where the worker identification card was read was the shipping inspection area.

[0028] In the shipping area, sorting work performance information is obtained as warehouse management information, and card reader information is obtained as behavior history information. In this case, the work performance information is information relating to the process of shipping work such as packing, and includes the time when the shipping work of the item was carried out and the item information of the item that was the subject of the shipping work. In this case, the card reader information includes worker information whose worker card was read by device 100 as a card reader, the time the worker card was read, and location information indicating that the location where the worker identification card was read is the shipping area.

[0029] The work analysis device 500 may create a productivity model using multivariate analysis such as multiple regression analysis as a work analysis for a specified work type, thereby estimating a model that best fits each factor and calculating the degree of impact on productivity. As a specific example, for picking work, items such as the number of workers, product type, delivery destination, work content, and time for each work content are used as independent variables (x1 to x n ), and the dependent variable (y) is the amount of work per person (i.e., "labor-hour productivity") calculated by dividing the total time required for one picking operation from the behavioral history by the number of workers (y=β0+β1x1+β2x2+···+β n x n ) may be used to create a productivity model. Various items that serve as independent variables may be obtained from warehouse management information. Based on such a productivity model, the work analysis device 500 can identify, from among the elements of a picking work, elements that have a high degree of contribution to improving productivity, and elements that do not contribute to improving productivity. The work analysis device 500 may present the results of identifying the relationship between productivity improvement and elements as described above on an analysis screen.

[0030] 3 shows an example of a productivity analysis screen that displays the results of an analysis of productivity at warehouse WH, as an analysis screen displayed on the warehouse terminal 300. The productivity analysis screen in the figure has a productivity element ranking area AR1 and a productivity performance area AR2.

[0031] The productivity element ranking area AR1 shows the ranking of the degree of contribution to improving productivity (work efficiency within the warehouse WH) for each element of the work identified by the work analysis device 500 based on the above-mentioned productivity model. In the same figure, the degree of contribution to improving productivity is shown as a numerical value shown as "degree of influence." The larger the "degree of influence" numerical value of an element, the greater the degree of contribution to improving productivity. A negative "degree of influence" value indicates that the element contributes to a decrease in productivity, and the larger the absolute value of the element, the greater the degree to which it reduces productivity.

[0032] Productivity performance results are presented in the productivity performance area AR2. In the figure, the productivity performance area AR2 has tabs for "Overall" and "By DAS," and the "By DAS" tab is shown selected. When the "By DAS" tab is selected, the productivity performance area AR2 displays average productivity values ​​for each of the multiple DASs (two in the example shown) used in warehouse WH, broken down by category (delivery destination, employment type, day of the week, time period, and intermediate classification name of the item).

[0033] FIG. 4 shows an example of a simulation screen, which is an analysis screen displayed on the warehouse terminal 300, on which a work time simulation is performed. The simulation screen in the figure has a data input area AR11 and a simulation result area AR12. The data input area AR11 is an area where data (files) indicating the target of work time simulation are input. The user as a warehouse manager inputs the data to be used for work time simulation by dragging and dropping it into the drag-and-drop area AR111 in the data input area AR11. Note that the operation of inputting the data to be used for work time simulation is not limited to drag-and-drop operation, and may be, for example, an operation of specifying the data (files) to be used for work time simulation and instructing the input of the specified file.

[0034] In response to data being input into the drag-and-drop area AR111, the contents of the input data are presented in the input data AR112. Furthermore, in response to data being input into the drag-and-drop area AR111, the work analysis device 500 performs a simulation of work time using the input data. The work analysis device 500 presents the simulation results in the simulation result area AR12.

[0035] In the figure, an example is given in which the data input to the input data AR112 is data indicating a list of types of goods scheduled to be received or shipped from the warehouse WH. The simulation result area AR12 in the same figure shows an example of the simulation results of the work time corresponding to all categories (item types) included in the input data (work time prediction for all data) and the simulation results of the work time by category (item type).

[0036] An example of the functional configuration of the work analysis device 500 according to this embodiment will be described with reference to FIG. The work analysis device 500 may be configured with hardware such as a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), and storage devices such as an HDD (Hard Disk Drive) or SSD (Solid State Drive). The functions of the work analysis device 500 shown in the figure are realized by the CPU included in the work analysis device 500 executing a program. The work analysis device 500 may also include a GPU (Graphics Processing Unit).

[0037] The work analysis device 500 in the figure includes a communication unit 501, a control unit 502, and a storage unit 503.

[0038] The communication unit 501 is connected to the warehouse management system 400, the warehouse terminal 300, the device 100, etc. via a network so as to be able to communicate with them.

[0039] The control unit 502 executes various controls in the work analysis device 500. The control unit 502 includes an information acquisition unit 521, an analysis unit 522, and a screen control unit 523.

[0040] The information acquisition unit 521 acquires warehouse management information to be used for work analysis from the warehouse management information storage unit 401 in the warehouse management system 400. The information acquisition unit 521 stores the acquired warehouse management information in the warehouse management information storage unit 531. Note that, for example, a user acting as a warehouse manager may operate the warehouse terminal 300 to cause the information acquisition unit 521 to acquire specified warehouse management information from the warehouse management information stored in the warehouse management information storage unit 401. Furthermore, the information acquisition unit 521 acquires information output from the device 100 in response to operation as behavior history information of the worker using the device 100. The information acquisition unit 521 stores the acquired behavior history information in the behavior history information storage unit 532. In this way, the work analysis device 500 stores warehouse management information and behavior history information that the analysis unit 522 uses when analyzing work.

[0041] The analysis unit 522 uses the warehouse management information stored in the warehouse management information storage unit 531 and the action history information stored in the action history information storage unit 532 to perform an analysis (work analysis) of a predetermined work item. In response to a request for a work analysis screen from a warehouse terminal 300 that has accessed the work analysis website, the analysis unit 522 may acquire warehouse management information and action history information necessary for work analysis corresponding to the requested work analysis screen from the warehouse management information storage unit 531 and the action history information storage unit 532, respectively. The analysis unit 522 may perform work analysis using the acquired warehouse management information and action history information. Alternatively, the analysis unit 522 may perform work analysis in advance using the warehouse management information stored in the warehouse management information storage unit 531 and the action history information stored in the action history information storage unit 532, and store the analysis results in the storage unit 503.

[0042] The screen control unit 523 generates a work analysis screen that visualizes the analysis results by the analysis unit 522 in a predetermined manner. The screen control unit 523 transmits the generated work analysis screen to the warehouse terminal 300. The warehouse terminal 300 displays the transmitted work analysis screen.

[0043] An example of a processing procedure executed by the work analysis device 500 and the warehouse management system 400 in relation to the accumulation of warehouse management information in the work analysis device 500 will be described with reference to the flowchart of FIG. First, an example of a processing procedure executed by the work analysis device 500 will be described. Step S100: In the work analysis device 500, the information acquisition unit 521 waits until it is time to acquire warehouse management information. The acquisition timing may be, for example, at regular intervals, or when the size of warehouse management information newly stored in the warehouse management information storage unit 401 since the previous accumulation of warehouse management information exceeds a predetermined size.

[0044] Step S102: When it is time to acquire warehouse management information, the information acquisition unit 521 transmits a warehouse management information request to the warehouse management system 400.

[0045] Step S104: The information acquisition unit 521 stores in the warehouse management information storage unit 531 the warehouse management information transmitted from the warehouse management system 400 in response to the transmission of the warehouse management information request in step S102.

[0046] Next, an example of a processing procedure executed by the warehouse management system 400 will be described. Step S200: The warehouse management system 400 receives the warehouse management information request sent from the work analysis device 500 in step S102.

[0047] Step S202: The warehouse management system 400 transmits to the work analysis device 500 the warehouse management information stored in the warehouse management information storage unit 401 that has been newly stored since the previous transmission of the warehouse management information in step S202.

[0048] An example of a processing procedure executed by the work analysis apparatus 500 and the device 100 in relation to the accumulation of action history information in the work analysis apparatus 500 will be described with reference to the flowchart of FIG.

[0049] First, an example of a processing procedure executed by the device 100 will be described. Step S300: The device 100 executes a predetermined operation in response to an operation by the worker.

[0050] Step S302: The device 100 outputs information according to the operation executed in step S300.

[0051] Next, an example of a processing procedure executed by the work analysis device 500 will be described. Step S400: The information acquisition unit 521 of the work analysis apparatus 500 receives the information transmitted from the device 100 in step S302. Alternatively, the information output from the device 100 may be temporarily stored in a predetermined data medium (not shown), and the stored information may be arranged in the work analysis apparatus 500 manually or automatically in response to a predetermined trigger, and the information acquisition unit 521 may acquire the arranged information.

[0052] Step S402: The information acquisition unit 521 stores the information received in step S400 in the behavior history information storage unit 532 as behavior history information.

[0053] An example of a processing procedure executed by the warehouse terminal 300 and the work analysis device 500 in relation to the display of the work analysis screen will be described with reference to the flowchart of FIG. Step S500: When a user as a warehouse manager performs an operation to transition to a certain work analysis screen while logged in to the work analysis website provided by the work analysis device 500, the warehouse terminal 300 sends a work analysis screen request to the work analysis device 500, specifying the work analysis screen to which the user is to transition.

[0054] Step S502: The warehouse terminal 300 displays on the display unit the work analysis screen transmitted from the work analysis device 500 in response to the transmission of the work analysis screen request in step S500.

[0055] Next, an example of a processing procedure executed by the work analysis device 500 will be described. Step S600: In response to receiving the work analysis screen request sent from the warehouse terminal 300 in step S500, the analysis unit 522 of the work analysis device 500 identifies the work analysis screen specified by the received work analysis screen request. The analysis unit 522 obtains, from the warehouse management information storage unit 531, warehouse management information to be used for work analysis that corresponds to the identified work analysis screen.

[0056] Step S602: Furthermore, the analysis unit 522 acquires, from the action history information storage unit 532, action history information to be used for the task analysis corresponding to the identified task analysis screen.

[0057] Step S604: The analysis unit 522 executes an analysis process corresponding to the work analysis, using the warehouse management information acquired in step S600 and the action history information acquired in step S602. If the received work analysis screen request specifies a productivity analysis screen such as that illustrated in FIG. 3 as the work analysis screen, the analysis unit 522 may create a productivity model using multivariate analysis and analyze productivity. 4, the received work analysis screen request includes data entered into the work analysis screen as the simulation screen displayed on the warehouse terminal 300. In this case, the analysis unit 522 executes analysis processing as a simulation using the warehouse management information acquired in step S600 and the behavior history information acquired in step S602, targeting, for example, the items indicated by the data included in the work analysis screen request.

[0058] Step S606: The screen control unit 523 generates an activity analysis screen that presents the results of the analysis processing in step S604. The activity analysis screen may be in the form of a web page, for example. The processing of steps S600 to S604 may be performed in advance at a predetermined timing, and the analysis results of step S604 may be stored in the storage unit 503. In this case, in response to the transmission of the work analysis screen request in step S500, the screen control unit 523 may generate a work analysis screen by processing step S606 using the analysis results stored in the storage unit 503.

[0059] Step S608: The screen control unit 523 transmits the work analysis screen generated in step S606 to the warehouse terminal 300.

[0060] In the above embodiment, the history information related to the analysis of work in the warehouse WH may include not only behavior history information indicating the behavioral history of workers, but also operation history information indicating the operation history of mobile objects such as forklifts, carts, and transport vehicles in the warehouse WH. The operation history information may include, for example, a movement history in which the movement path of the corresponding mobile object is associated with time, information indicating the loaded items, information on the load amount, etc.

[0061] The configuration of the above embodiment is not limited to application to the management of warehouses WH, but may also be applied to the analysis of work in factories, garages, etc., for example.

[0062] Note that a program for implementing the functions of the warehouse terminal 300, warehouse management system 400, work analysis device 500, etc. may be recorded on a computer-readable recording medium, and the program recorded on the recording medium may be loaded into a computer system and executed to perform the processes of the warehouse terminal 300, warehouse management system 400, work analysis device 500, etc. Here, "loading a program recorded on a recording medium into a computer system and executing it" includes installing the program on a computer system. The term "computer system" here includes hardware such as an operating system and peripheral devices. The term "computer system" may also include multiple computers connected via a network, including the Internet, a wide area network (WAN), a local area network (LAN), a dedicated line, or other communication line. The term "computer-readable recording medium" refers to portable media such as floppy disks, optical magnetic disks, ROMs, and CD-ROMs, as well as storage devices such as HDDs and SSDs built into a computer system. The recording medium storing the program may also be a non-transitory recording medium such as a CD-ROM. The term "recording medium" also includes internal or external recording media accessible from a distribution server for distributing the program. The program code stored on the recording medium of the distribution server may be different from the program code in a format executable by the terminal device. In other words, the format in which the program is stored on the distribution server is not important as long as it can be downloaded from the distribution server and installed in a format executable by the terminal device. The program may be divided into multiple parts, each downloaded at a different time and then combined on the terminal device, or each part may be distributed by a different distribution server. Furthermore, the term "computer-readable recording medium" also includes a storage medium that stores a program for a certain period of time, such as volatile memory (RAM) within a computer system that serves as a server or client when a program is transmitted over a network. The program may also be for implementing part of the functions described above.Furthermore, the above-mentioned functions may be realized in combination with a program already recorded in the computer system, that is, a so-called differential file (differential program).
