[0016] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0017] Fig. 1 is an overall view of a store system 1 according to this embodiment. The store system 1 is a system that manages the work of employees in a store that provides food and drink products, such as a restaurant. The store system 1 may manage one store or multiple stores.

[0018] The store system 1 comprises a work manager device 10, an order terminal device 20, an accounting device 30, and an administrator device 40. The work manager device 10, the order terminal device 20, the accounting device 30, and the administrator device 40 are connected via a network N such as a wireless LAN (Local Area Network). The work manager device 10 is configured, for example, from a stationary general-purpose computer or a cloud-type server, and manages the work of employees in a store such as a restaurant.

[0019] The order terminal device 20 is a smart device such as a handheld terminal, smartphone, or tablet terminal. The order terminal device 20 is carried by a user such as a waiter and is used to input orders from customers. The input information is sent to the accounting device 30. Although one order terminal device 20 is shown in the example shown in FIG. 1, there may be multiple order terminal devices 20. The accounting device 30 performs accounting processing for the ordered items. The manager device 40 is an information processing device used by a manager of the store system 1, etc. In this embodiment, the manager device 40 requests a work shift from the work manager device 10 in response to an operation by the manager, and when the manager device 40 receives the work shift, it displays it on the display unit 41.

[0020] The work manager device 10 includes a control unit 11, a storage unit 12, and a communication unit 13. The control unit 11 includes a processor such as a CPU (Central Processing Unit) and memories such as a ROM (Read Only Memory) and a RAM (Random Access Memory) for the processor to execute processes, and executes various processes. The control unit 11 executes various programs stored in the storage unit 12, the ROM, etc. The control unit 11 of this embodiment manages work and the like by executing the programs stored in the storage unit 12.

[0021] The control unit 11 of the duty manager device 10 includes, as functional units, a predicted sales amount acquisition unit 111, a work shift creation unit 112, a predicted man-hour sales amount calculation unit 113, an actual man-hour sales amount calculation unit 114, a difference calculation unit 115, and a display processing unit 116. The functions of the predicted sales amount acquisition unit 111, the work shift creation unit 112, the predicted man-hour sales amount calculation unit 113, the actual man-hour sales amount calculation unit 114, the difference calculation unit 115, and the display processing unit 116 are realized by the processor reading out a program stored in the memory unit 12 or the like and executing this program. In other words, the processes described as being executed by each of the above functional units are processes executed by the control unit 11.

[0022] The predicted sales acquisition unit 111 acquires predicted sales for each unit time of each day. Here, the unit time is a predetermined time, and is assumed to be a unit shorter than one day, such as one hour or 30 minutes. In restaurants and the like, sales vary depending on the day of the week and the time of day, so predicted sales for each unit time are acquired in this manner. The work shift creation unit 112 creates work shifts based on the predicted sales. A work shift includes the number of employees who should be working at each date and time, and identification information of the employees who will be working. Here, the employee identification information is the employee's name, etc. Here, employees include part-timers, casual employees, full-time employees, etc.

[0023] The predicted man-hour sales calculation unit 113 calculates the predicted man-hour sales. The actual man-hour sales calculation unit 114 calculates the actual man-hour sales. The predicted man-hour sales is the sales per unit time and per employee determined by the predicted sales and the number of employees indicated in the work shift. The actual man-hour sales is the actual sales per unit time and per employee determined by the actual sales (hereinafter referred to as actual sales) and the number of employees who actually worked (hereinafter referred to as actual number of employees). In restaurants and the like, labor costs fluctuate in addition to sales. Therefore, the man-hour sales is calculated as an index of profit. The difference calculation unit 115 calculates the man-hour sales difference, which is the difference between the actual man-hour sales and the predicted man-hour sales. In this embodiment, the difference calculation unit 115 obtains a value obtained by subtracting the predicted man-hour sales from the actual man-hour sales as the man-hour sales difference.

[0024] The display processing unit 116 displays the man-hour sales difference on the display unit 41 of the manager device 40. Specifically, the display processing unit 116 transmits the man-hour sales difference to the manager device 40. Then, the manager device 40 receives the man-hour sales difference and displays it on the display unit 41. Detailed processing in each functional unit of the work manager device 10 will be described later with reference to FIG. 2 etc.

[0025] FIG. 2 is a flowchart showing the first work management process by the work manager device 10. Here, one week is the processing target. However, the processing target period is not limited to this, and may be, for example, one day or one month. In the first work management process, the predicted sales amount acquisition unit 111 of the work manager device 10 acquires the predicted sales amount for each unit time in the processing target period (one week) (step S100). Here, the unit time is one hour. The predicted sales amount acquisition unit 111 acquires the predicted sales amount for each hour, such as the predicted sales amount at 16:00 and the predicted sales amount at 17:00, for each day in the processing target period. The predicted sales amount for each unit time is input by the manager via the manager device 40, and the predicted sales amount acquisition unit 111 acquires the predicted sales amount from the manager device 40 via the communication unit 13.

[0026] As another example, past sales are stored in the memory unit 12 of the work manager device 10, and the predicted sales amount acquisition unit 111 may determine the predicted sales amount from the past sales amount. For example, the predicted sales amount acquisition unit 111 may determine the sales amount for each hour of the day one week before the target day of processing as the predicted sales amount for each hour of the target day of processing.

[0027] Next, the work shift creation unit 112 creates work shifts for the period to be processed (step S102). Specifically, first, the number of employees to be employed (hereinafter referred to as the planned number of employees) is determined based on the predicted sales amount in each unit time. In this manner, the work shift creation unit 112 determines the planned number of employees. In other words, the work shift creation unit 112 is an example of an employee number determination unit that determines the planned number of employees based on the predicted sales amount.

[0028] Next, the work shift creation unit 112 assigns employees scheduled to work to each time period according to the determined number of employees scheduled to work. The employee assignment is performed in response to the manager's operation of the manager device 40 in accordance with the wishes of the employees. As another example, each employee may input the time period during which they wish to work on an employee device such as a mobile terminal (not shown) carried by the employee, and employees may be assigned in response to this input. With the number of employees determined and the employee assignment completed, the work shift is complete.

[0029] As another example, a sales standard range, which is a standard range of predicted man-hour sales, may be set in advance. In this case, the work shift creation unit 112 determines the number of employees scheduled for each unit time so that the predicted man-hour sales falls within the sales standard range. This automatically allocates the number of employees to achieve the desired predicted man-hour sales.

[0030] Next, the predicted man-hour sales calculation unit 113 calculates the predicted man-hour sales for each unit time based on the planned number of employees for each unit time indicated in the work shift and the predicted sales for each corresponding unit time (step S104). For example, if the predicted sales for a unit time is x and the planned number of employees for a unit time is y, then x / y is the predicted man-hour sales for the unit time. The predicted sales, planned number of employees, and predicted man-hour sales obtained in the first work management process are stored in the memory unit 12 together with the work shift.

[0031] FIG. 3(a) shows a bar graph of forecasted sales. The horizontal axis indicates time, and the vertical axis indicates forecasted sales. FIG. 3(b) shows a bar graph of the planned number of employees. The horizontal axis indicates time, and the vertical axis indicates the planned number of employees. FIG. 3(c) shows a bar graph of forecasted sales per man-hour. The horizontal axis indicates time, and the vertical axis indicates forecasted sales per man-hour. The forecasted sales shown in FIG. 3(c) is calculated based on the forecasted sales shown in FIG. 3(a) and the planned number of employees shown in FIG. 3(b).

[0032] Next, the second work management process by the work manager device 10 will be described. FIG. 4 is a flowchart showing the second work management process. The second work management process is executed after the period to be processed in the first work management process has elapsed, with a period within the elapsed period as the processing target. This process is executed, for example, when an execution request is received from the manager device 40. In this case, the processing target is specified together with the execution request.

[0033] First, the actual sales amount calculation unit 114 processes a predetermined period that has passed, and obtains the actual sales amount per unit time within the predetermined period from the accounting device 30 via the communication unit 13 (S200). Here, the predetermined period may be the same as or different from the period that is the subject of processing in the first work management process.

[0034] Next, the actual manned sales calculation unit 114 obtains the actual number of employees per unit time in the period to be processed (S202). Here, the actual number of employees is the number of employees who actually worked. The actual number of employees is assumed to be input, for example, in response to an operation of the manager device 40 by the manager. The actual manned sales calculation unit 114 then obtains the actual number of employees from the manager device 40 via the communication unit 13. Next, the actual manned sales calculation unit 114 calculates the actual manned sales per unit time in the period to be processed based on the actual sales amount and the actual number of employees (S204).

[0035] FIG. 5(a) shows a bar graph of actual sales. The horizontal axis indicates time, and the vertical axis indicates actual sales. FIG. 5(b) shows a bar graph of the actual number of employees. The horizontal axis indicates time, and the vertical axis indicates the actual number of employees. FIG. 5(c) shows a bar graph of actual sales during working hours. The horizontal axis indicates time, and the vertical axis indicates actual sales during working hours. Based on the actual sales shown in FIG. 5(a) and the actual number of employees shown in FIG. 5(b), the actual sales during working hours shown in FIG. 5(c) are calculated.

[0036] Actual sales may differ from forecast sales. Also, the actual number of employees may differ from the planned number of employees due to, for example, sudden absences by employees, overtime work due to busy schedules, etc. Due to these factors, actual sales per person-hour may differ from forecast sales per person-hour.

[0037] Next, the difference calculation unit 115 calculates a man-hour sales difference, which is the difference between the actual man-hour sales and the predicted man-hour sales (S206). Next, the display processing unit 116 displays the man-hour sales difference on the display unit 41 of the administrator device 40 (S208). Specifically, the display processing unit 116 transmits the man-hour sales difference to the administrator device 40 via the communication unit 13.

[0038] 6 is a diagram showing a display screen 400 of the man-hour sales difference displayed on the display unit 41 of the administrator device 40. A bar graph showing the man-hour sales difference is displayed on the display screen 400. The horizontal axis of the graph of the man-hour sales difference shows time, and the vertical axis shows the man-hour sales difference.

[0039] Furthermore, the display processing unit 116 displays the bars in the time slots in which the actual man-hour sales are smaller than the predicted man-hour sales and the man-hour sales, which is the difference between the predicted man-hour sales and the actual man-hour sales, is equal to or larger than the warning threshold, in a color different from the bars in the other time slots. For example, as shown in FIG. 6, in the time slots of 21:00 and 22:00, the actual man-hour sales are smaller than the predicted man-hour sales and the difference between the predicted man-hour sales and the actual man-hour sales is equal to or larger than the warning threshold. Furthermore, in the other time slots (16:00 to 20:00), the actual man-hour sales are greater than the predicted man-hour sales. In this case, 21:00 and 22:00 are classified as the first time slot, and the bars corresponding to these time slots are displayed with diagonal hatching. Moreover, the time slots other than the first time slot, that is, 16:00 to 20:00, are classified as the second time slot, and the bars corresponding to these time slots are displayed in white without hatching. The warning threshold is a preset value. In this embodiment, the warning threshold is a negative value, but the warning threshold can be set arbitrarily. For example, the warning threshold may be zero or a positive value.

[0040] In this embodiment, the first time zone and the second time zone are displayed with or without hatching, but as long as the two time zones are displayed in different display modes so that they can be distinguished, the display modes are not limited to those in the embodiment. As another example, the bars for the two time zones may be displayed in different colors. As another example, the frame of the bar for the first time zone may be displayed with a thicker line than the frame of the bar for the second time zone.

[0041] In this way, by displaying each time period in a different manner, the manager can understand that there were an excess of employees between 9 p.m. and 10 p.m., in other words, that the work being done was not commensurate with sales.

[0042] In restaurants and other establishments, during busy hours, unscheduled employees may be working. On the other hand, even when it is not busy, there may be more employees than expected for the work shift working wastefully. However, in the past, it was difficult to identify such wasteful work. In contrast, the work manager device 10 of this embodiment can automatically extract time periods during which wasteful work may have been performed and display them in a manner that makes them distinguishable from other time periods. Therefore, with the work manager device 10 of this embodiment, the manager can easily check whether or not there is wasteful work. This in turn can reduce labor costs.

[0043] The above embodiment is an example for implementing the present invention, and various other embodiments can be adopted. For example, various modifications and changes are possible within the scope of the gist of the present invention described in the claims, such as applying one modified example to another modified example. For example, the present invention may be realized as a work management system in which multiple functional units constituting the work manager device 10 are distributed to different devices. In addition, some of the configurations of the above-mentioned embodiment may be omitted, and the order of processing may be changed or omitted.

[0044] As a first variant example, the predicted man-hour sales amount calculation process (step S104) in the first work management process described with reference to Figure 2 may be executed before the man-hour sales amount difference calculation process (S206) in the second work management process, and the execution timing is not limited to that of the embodiment.

[0045] As a second modified example, the period to be processed in the second work management process is not limited to the embodiment. In addition, the execution timing of the second work management process is not limited to the embodiment. For example, the second work management process may be executed after the end of business hours for one week that is the processing target of the first work management process, with the one week as the processing target. In addition, as another example, the second work management process may be executed after the end of business hours for one week, with the specified day as the processing target, when a specific day of the week is specified by the manager.

[0046] As a third variant, the first time period may be limited to time periods during which actual man-hour sales are smaller than predicted man-hour sales and the difference is greater than or equal to the warning threshold, and further limited to time periods during which the actual number of employees is greater than the planned number of employees.

[0047] When the actual man-hour sales are smaller than the predicted man-hour sales and the difference is equal to or greater than the warning threshold, it is assumed that the actual number of employees is too large compared to the actual sales, or that the actual sales are smaller than the predicted sales. By showing these cases separately, the manager can easily understand that more people than were scheduled to work in the work shift were working.

[0048] As a fourth modified example, the display processing unit 116 may classify, among the time periods when the actual man-hour sales are smaller than the predicted man-hour sales and the man-hour sales difference is equal to or greater than the warning threshold, the time periods when the actual number of employees is equal to or less than the planned number of employees as the third time period. Then, the display processing unit 116 causes the display unit 41 to display the first time period, the second time period, and the third time period so that they can be distinguished from one another.

[0049] For example, as shown in Figures 3(b) and 5(b), at 20:00, the actual number of employees was greater than the planned number of employees, and therefore the actual man-hour sales were less than the predicted man-hour sales. On the other hand, at 21:00, although the actual number of employees was equal to the planned number of employees, the actual sales were less than the predicted sales, and therefore the actual man-hour sales were less than the predicted man-hour sales. Therefore, the display processing unit 116 classifies 21:00 as the third time slot.

[0050] FIG. 7 is a diagram showing an example of a display screen 410 according to this modified example. As shown in FIG. 7, the bars of the first time period are displayed with diagonal hatching that slopes upward to the right, and the bars of the second time period are displayed in white without hatching. Furthermore, the bars of the third time period are displayed with hatching that slopes downward to the right. This makes it possible to distinguish and display the time periods in which the actual man-hour sales are smaller than the predicted man-hour sales and the man-hour sales difference is equal to or greater than the warning threshold value as time periods in which the actual number of employees is equal to or less than the planned number of employees and time periods in which the actual number of employees is greater than the planned number of employees. Therefore, the manager can distinguish and grasp these time periods.

[0051] As a fifth modified example, the display processing unit 116 may display a band showing each time period instead of displaying the man-hour sales difference, and may display the first time period, the second time period, and even the third time period in the band in a distinguishable manner. FIG. 8 is a diagram showing an example of a display screen 420 according to this modified example. As shown in FIG. 8, the display screen 420 shows a band showing 16:00 to 22:00, and the areas corresponding to the first time period, the second time period, and the third time period are displayed in different display modes. In this way, it is sufficient that the first time period, the second time period, and even the third time period are displayed in a distinguishable manner for the user, and the specific display mode for this is not limited to the embodiment. In addition, as another example, a line graph with the horizontal axis representing time and the vertical axis representing the difference may be displayed. In this case, the first time period and the second time period are also displayed in a distinguishable manner from the values ​​of the graph.

[0052] As a sixth modified example, the display processing unit 116 may further set a time period in which the actual man-hour sales amount is greater than the predicted man-hour sales amount and the man-hour sales amount difference is equal to or greater than the warning threshold as a fourth time period, and display the fourth time period in a display mode different from the first time period and the second time period. Furthermore, the fourth time period may also be displayed in a display mode different from the third time period. FIG. 9 is a diagram showing an example of a display screen 430 according to this modified example. As shown in FIG. 9, 5 p.m. is classified as the fourth time period, and the bar for the fourth time period is displayed with hatching of dots.

[0053] As a seventh modified example, the display processing unit 116 may display the actual man-hour sales amount on the display unit 41 instead of the man-hour sales amount difference. In this case, by checking the actual man-hour sales amount and the display mode of each time period, the manager can check whether there is any unnecessary work.

[0054] As an eighth modified example, in the case where the duty manager device 10 is provided with a display unit, the display processing unit 116 may cause the display unit of the duty manager device 10 to display the man-hour sales amount difference.

[0055] FIG. 10 is a diagram showing the configuration of the work manager device 10 according to the ninth modification. In this modification, the control unit 11 of the work manager device 10 includes a warning unit 117 instead of the display processing unit 116. The warning unit 117 issues a warning when the actual man-hour sales are smaller than the predicted man-hour sales and the man-hour sales difference is equal to or greater than the warning threshold value in a certain unit time within the processing period. Specifically, the warning unit 117 specifies a unit time and transmits information to the manager device 40 to inform the manager that the actual man-hour sales are smaller than the predicted man-hour sales and the man-hour sales difference is equal to or greater than the warning threshold value in the unit time. The information may be text information displayed on the display unit 41 to the effect that the actual man-hour sales are smaller than the predicted man-hour sales and the man-hour sales difference is equal to or greater than the warning threshold value, or an icon indicating the effect. As another example, if the manager device 40 includes a speaker, the information may be output as audio.

[0056] FIG. 11 is a diagram showing the configuration of the duty manager device 10 according to the tenth modified example. In the duty manager device 10 of this example, the control unit 11 includes a predicted man-hour profit calculation unit 141 and an actual man-hour profit calculation unit 142 in addition to the functional configuration of the control unit 11 of the duty manager device 10 according to the embodiment. The predicted man-hour profit calculation unit 141 calculates a predicted man-hour profit based on the predicted man-hour sales. The actual man-hour profit calculation unit 142 calculates an actual man-hour profit based on the actual man-hour sales. In this case, the difference calculation unit 143 calculates the difference between the actual man-hour profit and the predicted man-hour profit. Then, the display processing unit 116 classifies the time periods into a first time period and a second time period according to the difference, and displays them in an identifiable manner.

[0057] Furthermore, the tenth modified example may be applied to the ninth modified example, and the warning unit 117 may issue a warning when the difference between the actual person-hour profit and the predicted person-hour profit is equal to or greater than a warning threshold.

[0058] Furthermore, the present invention can be applied as a program or a method. The above-mentioned system, program, and method may be realized as a single device or may be realized by using shared components, and include various aspects. For example, it is possible to provide a method or program realized by the above-mentioned system. Also, it is possible to change it as appropriate, such as partly being software and partly being hardware. Furthermore, the invention can be established as a recording medium of a program that controls the device.
