Description

The present disclosure relates to a work management device, and in particular to a work management device that adjusts the work hours of workers performing maintenance work on a toilet room equipped with multiple cubicles.

JP 2022-19085 A (Patent Document 1) discloses a service support system that can support service providers at facilities. For example, for toilet cleaning services, this support system identifies toilets and time periods suitable for providing cleaning services based on aggregated data on the number of toilet users. For example, based on the criterion that time periods with fewer toilet users are suitable for cleaning, toilets and time periods with fewer users than a predetermined number are identified, and this information is provided to the service provider (cleaning worker) as service support information (see Patent Document 1).

Japanese Patent Application Laid-Open No. 2022-19085

When it comes to restroom maintenance work, workers' initial response is often short, and it's best to complete the work quickly. However, when workers work in a restroom for the opposite sex (especially when a male worker works in a women's restroom), there's a risk that users may become upset. As a result, even when workers arrive at the site, they may have to wait longer than necessary until the line of users clears, or they may have to perform the work during overtime hours after the facility closes, which increases the costs of the work.

This disclosure has been made to solve this problem, and its purpose is to provide a work management device that enables workers performing maintenance work on toilets to perform their work promptly at the time of their choice.

The work management device disclosed herein adjusts the work hours of workers performing maintenance work on a restroom equipped with multiple stalls. It includes a communications device that acquires the desired time slot and required time for the worker's maintenance work from the worker's terminal device, and a processing device that executes processing to adjust the work time based on the desired time slot and required time acquired by the communications device. The processing device calculates the utilization rate and average utilization time per restroom stall for each specified time slot based on the time and duration of use of the stalls collected for each of the multiple stalls, and extracts, from the specified time slots, time slots that satisfy first to third conditions as candidate work times. Here, the first condition is that the time difference from the desired time slot is less than a specified time, the second condition is that the utilization rate is lower than a threshold, and the third condition is that the time obtained by subtracting the average utilization time from the length of the specified time slot is longer than the required time.

With the above configuration, candidate work times are extracted taking into account the worker's desired work time and the availability of the restroom. Based on the extracted candidate work times, the worker can select a time slot that is close to the desired work time and allows the work to be completed quickly, and then carry out the work.

The work management device disclosed herein allows workers performing maintenance work on restrooms to perform their work promptly during the desired time slot.

Embodiments of the present disclosure will now be described in detail with reference to the drawings. Note that identical or equivalent parts in the drawings will be designated by the same reference numerals and their description will not be repeated.

Figure 1 shows the overall configuration of a work time adjustment system according to an embodiment of the present disclosure. This work time adjustment system is a system for adjusting the work time of workers performing maintenance work on restrooms used by an unspecified number of people in commercial facilities such as shopping malls.

Referring to FIG. 1, the work time adjustment system 1 includes a toilet room 10, a usage management server 20, a work management server 30, and a terminal device 40. The toilet room 10, the usage management server 20, the work management server 30, and the terminal device 40 are each provided with a communication device, and the toilet room 10, the usage management server 20, the work management server 30, and the terminal device 40 can communicate via a network 50.

Toilet room 10 is one of the toilet rooms provided in a commercial facility such as a shopping mall that can be used by an unspecified number of users, and is the subject of maintenance work by workers. In the following, toilet room 10 is assumed to be a women's toilet room, and toilet room 10 has multiple private rooms.

The usage management server 20 is the management server for the "Toilet Usage Status Providing System," which detects the usage status of the toilet room 10 and provides a service that displays this information to those who wish to use it. The usage management server 20 collects the usage status of each stall in the toilet room 10 and executes processing to display the usage status of the toilet room 10 on a display device installed at the entrance/exit of the toilet room 10 or on the user's mobile device, etc.

The work management server 30 executes a series of adjustment processes to enable the worker performing maintenance work on the toilet room 10 to carry out the work promptly during the desired time period.

When it comes to restroom maintenance work, workers' initial response is often completed in a short amount of time, and they want to complete the work quickly, but if a male worker works in a women's restroom, there is a risk that users may become upset (the same is true if a female worker works in a men's restroom). As a result, even if a worker heads to the site, they may have to wait longer than necessary until there are no users, or they may have to work during overtime hours after the facility closes, which increases the costs of the work.

The work management server 30 therefore executes a process to adjust the time the worker will work in the toilet room 10 based on the worker's desired work time and required time, which are acquired from the worker's terminal device 40, and the usage status of the toilet room 10, which is acquired from the usage management server 20. This adjustment process by the work management server 30 enables the worker to perform the work in a time period that is close to the worker's desired work time and allows the work to be performed quickly.

The terminal device 40 is the terminal device of the worker performing maintenance work on the toilet room 10, and the worker can exchange various information with the work management server 30 through the terminal device 40. Specifically, the worker can input the desired time period and required time for the work from the terminal device 40. The terminal device 40 also displays candidate work time periods presented by the work management server 30 based on the desired time period and required time, and the worker can select the desired scheduled work time from the displayed candidate work time periods. This terminal device 40 is configured, for example, as a tablet, smartphone, or personal computer. The overall processing flow of the work time adjustment system 1, which is performed by the usage management server 20, the work management server 30, and the terminal device 40, will be explained in detail later.

Figure 2 is a diagram showing an example of the floor plan of the toilet room 10 shown in Figure 1. Referring to Figure 2, this toilet room 10 is provided with three cubicles 11-1 to 11-3. Note that the number of cubicles is not limited to this. The cubicles 11-1 to 11-3 are each provided with door sensors 12-1 to 12-3 that detect the open/closed state of the door. Note that hereinafter, the cubicles 11-1 to 11-3 may be referred to as "cubicles 11" without distinction from one another, and the door sensors 12-1 to 12-3 may be referred to as "door sensors 12" without distinction from one another.

In this example, the occupancy status of each private room 11 is detected by detecting the open/closed state of the door using the door open/close sensor 12. Note that instead of the door open/close sensor 12, the occupancy status of the private room 11 may be detected using a key sensor that detects the open/closed state of the door lock, or a human presence sensor that uses infrared light, etc.

The toilet room 10 is further provided with a communication device 13. The communication device 13 is capable of communicating with the door opening/closing sensor 12 and receives a detection signal indicating the open/closed state of the door from the door opening/closing sensor 12. The communication device 13 is also capable of communicating with the usage management server 20 (Figure 1) via the network 50 and transmits the detection signal of the door opening/closing sensor 12 to the usage management server 20.

A display device 15 is provided near the entrance 14 of each toilet room 10. The display device 15 is connected to the communication device 13 and displays the usage status (occupied/vacant) of each cubicle 11 based on the detection signal of the door opening/closing sensor 12. This display device 15, the usage management server 20, the door opening/closing sensor 12, and the communication device 13 constitute a "toilet usage status providing system" that detects the usage status of the toilet room 10 and provides a service that displays the status to users.

In addition, when the scheduled time for the worker to work in the toilet room 10 approaches, the display device 15 can display a notification that the worker will be working in the toilet room 10, or can display that the worker is currently working. This point will be explained in more detail later.

Figure 3 is a diagram showing an example of the hardware configuration of the usage management server 20 shown in Figure 1. Referring to Figure 3, the usage management server 20 includes a processing device 21, a communication device 24, a usage time database (DB) 25, and a communication bus 26.

The processing device 21 is composed of a CPU (Central Processing Unit) 22 and memory 23 including RAM (Random Access Memory) and ROM (Read Only Memory). The CPU 22, memory 23, communication device 24, and usage time DB 25 can exchange various data via a communication bus 26.

The CPU 22 loads the program stored in the ROM into the RAM and executes it. The program stored in the ROM describes various processes to be executed by the processing device 21. The communication device 24 is configured to be able to communicate with the communication device 13 installed in the toilet room 10 and the work management server 30.

The usage time DB 25 is a storage device that accumulates the usage status of the cubicles 11 in the toilet room 10. The processing device 21 sequentially stores the usage time and usage duration of each cubicle 11-1 to 11-3 in the toilet room 10 in the usage time DB 25 based on the detection signal of the door opening/closing sensor 12 in the toilet room 10 received by the communication device 24.

Figure 4 shows an example of the data structure of the usage time DB 25. Referring to Figure 4, the usage time DB 25 stores information such as the start date and time of use, end date and time of use, and usage time for each private room 11, along with the building name, floor number, room name, and private room number.

"Building name" indicates the name of the building in which the toilet room 10 is located. "Floor" indicates the floor on which the toilet room 10 is located. "Room name" indicates the name of the toilet room 10. "Standby number" is the number assigned to stalls 11-1 to 11-3 within the toilet room 10. "Start of use" indicates the date, day of the week, and time when use began for each stall 11. "End of use" indicates the date, day of the week, and time when use ended for each stall 11. "Usage time" indicates the time from the start of use to the end of use for each stall 11. Note that symbol A in the figure is data showing usage status between 9:00 a.m. on Monday, June 6, 2022.

Figure 5 is a diagram showing an example of the hardware configuration of the work management server 30 shown in Figure 1. Referring to Figure 5, the work management server 30 includes a processing device 31, a communication device 34, a table database (DB) 35, and a communication bus 36.

The processing device 31 includes a CPU 32 and a memory 33 including RAM and ROM. The CPU 32, memory 33, communication device 34, and table DB 35 can exchange various data via a communication bus 36.

The CPU 32 loads the program stored in the ROM into the RAM and executes it. The program stored in the ROM describes various processes to be executed by the processing device 31. The communication device 34 is configured to be able to communicate with the usage management server 20 and the worker's terminal device 40 (Figure 1).

Table DB35 is a storage device that stores various tables used by the work management server 30. Table DB35 includes a private room utilization rate table, a candidate work time table, and a scheduled work time table.

The cubicle utilization rate table is a data table that shows the utilization rate per cubicle in the toilet room 10 (hereinafter also referred to as "cubicle utilization rate") and average utilization time (hereinafter also referred to as "average cubicle utilization time") for each time period. In this example, the length of a time period is one hour, and the cubicle utilization rate and average cubicle utilization time for each time period (9:00, 10:00, etc.) are stored in the table.

A higher cubicle utilization rate indicates that the toilet room 10 is used more frequently. Furthermore, a longer average cubicle utilization time indicates a longer average utilization time of the toilet room 10 (average time per cubicle utilization). As described below, this cubicle utilization rate and average cubicle utilization time are used to adjust the work time of workers in the toilet room 10. This cubicle utilization rate table is created in a timely manner by the processing device 31. The method for creating the cubicle utilization rate table will be explained later.

The candidate work time table is a data table that shows candidate time periods when a worker can perform maintenance work, based on the worker's desired time period and required time for the work, which are input from the worker's terminal device 40. This candidate work time table is created by extracting time periods that meet specified conditions from the private room utilization rate table, using the desired time period and required time, and the private room utilization rate and average private room utilization time for each time period shown in the private room utilization rate table. When the desired time period and required time for the work are input into the terminal device 40, this candidate work time table is created by the processing device 31 in response to the input information. The method for creating the candidate work time table will be explained later.

The planned work time table is a data table showing the planned work time periods selected by the worker from the candidate work time table. The candidate work time periods shown in the candidate work time table are sent to and displayed on the terminal device 40, and when the worker selects a planned work time period from the candidate work time periods, the processing device 31 creates a planned work time table. According to this planned work time table, the display device 15 in the toilet room 10 displays the planned work and information that work is currently being done.

Figure 6 is a flowchart explaining the processing flow in the work time adjustment system 1. Referring to Figure 6, the usage management server 20 collects data regarding the usage status of the toilet room 10 (step S10). In detail, the usage management server 20 receives detection signals from the door opening/closing sensors 12 installed in each stall 11 of the toilet room 10 via the communication device 13 (Figure 2) of the toilet room 10, and based on the detection signals, sequentially stores the usage time and usage duration of each stall 11 of the toilet room 10 in the usage time DB 25 (Figure 4).

The work management server 30 acquires from the usage management server 20 the data collected in the usage time DB 25 of the usage management server 20, and calculates the cubicle utilization rate and average cubicle utilization time of the toilet room 10 for each time period (in this example, in one-hour increments) (step S12). Specifically, the cubicle utilization rate and average cubicle utilization time of the toilet room 10 are calculated using the following formulas.

Private room occupancy rate (%) = (total usage time during the time period) / (number of private rooms x 60 minutes) x 100... (1)
Average private room usage time = (total usage time during the time period) / (number of times private rooms were used) ... (2)
For example, from the data indicated by symbol A in Figure 4, the occupancy rate and average occupancy time of the toilet room 10 in the 9:00 hour on June 6, 2022 are calculated as follows.

Private room occupancy rate = (39 minutes 45 seconds) / (3 private rooms x 60 minutes) x 100 = 22.1 (%)
Average private room usage time = (39 minutes 45 seconds) / (7 times) = 5 minutes 41 seconds The work management server 30 calculates the private room usage rate and average private room usage time, for example, every time period, every few hours, or once a day, and stores the calculation results in the private room usage rate table (step S14).

Figure 7 shows an example of the data structure of a private room utilization rate table. Referring to Figure 7, the private room utilization rate table stores data for each time period, such as the building name, floor number, room name, date, time period, private room utilization rate, average private room utilization time, total utilization time, and number of private rooms.

The data indicated by symbol B is data on the cubicle occupancy rate and average cubicle usage time of toilet room 10 from 9:00 AM on June 6, 2022, calculated from the data indicated by symbol A (Figure 4) in the usage time DB 25. In this way, the cubicle occupancy rate and average cubicle usage time of toilet room 10 for each time period (in one-hour increments in this example) are calculated from the usage time DB 25 collected by the usage management server 20, and stored in the cubicle occupancy rate table.

Referring again to FIG. 6, when a worker performing toilet maintenance work receives notification of a malfunction in the toilet room 10, the worker inputs the desired time period and required time for the work from the terminal device 40 (step S20). The input desired time period and required time are transmitted to the work management server 30. The worker can also receive notification of a malfunction in the toilet room 10 from, for example, the facility's monitoring center or information center.

When the work management server 30 receives the desired time period and required time for the work from the terminal device 40, it extracts time periods that meet the following conditions from the private room occupancy rate table as candidate work times based on the desired time period and required time (step S22).

First condition: The difference from the desired time slot is less than a predetermined time. Second condition: Private room occupancy rate < threshold value. Third condition: (length of time slot - average private room usage time) > required time. In the above, the "predetermined time" of the first condition is set to, for example, one hour. In other words, the first condition is the desired time slot and a time slot one hour before and after it. The "threshold value" of the second condition is set to, for example, 20-25%. Note that the threshold setting is not limited to this. The "length of time slot" of the third condition is one hour in this example. Note that in this example, the time slots in the private room occupancy rate table are in one-hour units, but they may be more specific, in 30-minute units, or longer than one hour.

Then, the work management server 30 stores the time period data extracted from the private room occupancy rate table based on the desired time period and required time for the work in the candidate work time table as a candidate work time (step S24).

Figure 8 is a diagram showing an example of the data structure of the candidate work time table. Referring to Figure 8, the candidate work time table stores data such as building name, floor, room name, time period, private room occupancy rate, and average private room usage time for time periods that satisfy the first to third conditions described above. In this example, the data is stored in order of priority, with time periods with low private room occupancy rates at the top. However, if a time period includes a work time period input from terminal device 40 in step S20, that time period may be given the highest priority, or the priority may be higher in order of shortest average private room usage time.

Referring again to FIG. 6, the work management server 30 transmits the candidate work time periods stored in the candidate work time table to the worker's terminal device 40 (step S26). The terminal device 40 then displays the candidate work time periods received from the work management server 30 on its display unit (step S28). Note that when displayed, the time periods with the highest priority in the candidate work time table are displayed at the top.

In step S20, the worker inputs the desired work time period and required time from the terminal device 40, and can select the desired planned work time period from the candidate work time periods displayed on the terminal device 40. The terminal device 40 then transmits the planned work time period selected by the worker to the work management server 30 (step S30).

When the work management server 30 receives the planned work time period from the terminal device 40, it stores the received planned work time period in the planned work time table (step S32).

Figure 9 shows an example of the data structure of the planned work time table. Referring to Figure 9, the planned work time table stores data for time periods selected by the worker on the terminal device 40 from the data in the candidate work time table shown in Figure 8.

At this time, the "time slot" data in the candidate work time table is stored as the "scheduled work time slot," and the "average private room usage time" data in the candidate work time table is stored as the "estimated private room usage time." In this example, of the data in the candidate work time table shown in Figure 8, the data for the 4:00 PM time slot is stored in the scheduled work time table.

Referring again to FIG. 6, the work management server 30 transmits the data of the planned work time stored in the planned work time table to the usage management server 20 (step S34). Specifically, the work management server 30 notifies the usage management server 20 that the "planned work time zone" is "between 4 p.m." and that the "expected private room usage time" is "9 minutes 23 seconds" (hereinafter referred to as "X minutes").

When the usage management server 20 receives the above data regarding the scheduled work time from the work management server 30, it displays the work schedule for the restroom 10 on the display device 15 (Figure 1) based on the received data. In more detail, the usage management server 20 displays a notification on the display device 15 that the restroom 10 will be prohibited from use because work will be carried out by workers in the restroom 10 after the time indicated by the "estimated cubicle use time" (i.e., around 4 p.m.) when the time indicated by the "estimated cubicle use time" (X minutes before in this example) precedes the time indicated by the "scheduled work time zone" (in this example, around 4 p.m.) (step S36).

Figure 10 is a diagram showing an example of a notification displayed on the display device 15 of the toilet room 10 in step S36 of Figure 6. Referring to Figure 10, the usage management server 20 displays a notification on the display device 15 of the toilet room 10, stating "Use prohibited due to scheduled toilet work in X minutes (for example, 9 minutes in this example)," based on the data of the scheduled work time received from the work management server 30.

Referring again to FIG. 6, the usage management server 20 monitors the usage status of the toilet room 10, and when it detects a user in the toilet room 10 at the scheduled work time (between 4 p.m. in this example) (step S38), it notifies the work management server 30 of this fact. In response to the notification from the usage management server 20, the work management server 30 notifies the terminal device 40 that a user is present in the toilet (step S40), and this fact is displayed on the terminal device 40 (step S42). This allows the worker to recognize that maintenance work cannot begin because there is still a user in the toilet room 10.

On the other hand, if the usage management server 20 detects that there are no users in the toilet room 10 at the scheduled work time (between 4 p.m. in this example) (step S44), it notifies the work management server 30 of this fact. In response to the notification from the usage management server 20, the work management server 30 notifies the terminal device 40 that there are no users in the toilet room (step S46), and this fact is displayed on the terminal device 40 (step S48). This allows the worker to know that maintenance work on the toilet room 10 can begin.

When the worker confirms on the terminal device 40 that no one is using the restroom 10, they input a command to start work from the terminal device 40. The terminal device 40 then transmits a notification that the worker has started work to the work management server 30 (step S50), and the work management server 30 notifies the usage management server 20 that the worker has started work (step S52). Upon receiving the notification from the work management server 30, the usage management server 20 displays on the display device 15 (Figure 1) of the restroom 10 that the worker is working (step S54).

Figure 11 shows an example of a notification displayed on the display device 15 of the toilet room 10 in step S54 of Figure 6. Referring to Figure 11, the usage management server 20 displays a notification "Male worker working in toilet" on the display device 15 of the toilet room 10 (women's) based on the notification of the start of work received from the work management server 30.

Figure 12 is a flowchart illustrating an example of the steps for the private room occupancy rate table storage process executed by the work management server 30. Note that the series of processes shown in this flowchart are executed at a predetermined frequency (for example, every time period, every few hours, or once a day).

Referring to FIG. 12, the work management server 30 acquires data on the use time and use duration of each stall 11 in the toilet room 10 from the usage management server 20 (step S110). The data on the use time and use duration of the toilet room 10 is stored in the usage time DB 25 (FIG. 4) of the usage management server 20.

Next, the work management server 30 uses the above-mentioned formulas (1) and (2) to calculate the private room utilization rate and average private room utilization time for each time period from the utilization time and utilization duration data acquired from the usage management server 20 (step S120). The work management server 30 then stores the calculated private room utilization rate and average private room utilization time for each time period in the private room utilization rate table (Figure 7) (step S130).

Figure 13 is a flowchart illustrating an example of the procedure for work time adjustment processing executed by the work management server 30. The series of processes shown in this flowchart are repeatedly executed at a predetermined interval.

Referring to FIG. 13, the work management server 30 determines whether the desired time period and required time for work on the toilet room 10 have been received from the worker's terminal device 40 (step S210). If the desired time period and required time have not been received from the terminal device 40 (NO in step S210), the process proceeds to return without executing the subsequent series of processes.

If it is determined in step S210 that the desired time period and required time for the work have been received from the terminal device 40 (YES in step S210), the work management server 30 extracts data for time periods that satisfy the first to third conditions from the private room occupancy rate table (Figure 7) (step S220). The first to third conditions have already been explained, so they will not be explained again here.

The work management server 30 then stores the extracted time period data in the candidate work time table (Figure 8) (step S230). The work management server 30 then transmits the candidate work time periods stored in the candidate work time table to the terminal device 40 (step S240). In response to transmitting the candidate work time periods to the terminal device 40, when the work management server 30 receives from the terminal device 40 the planned work time periods selected by the worker on the terminal device 40 (YES in step S250), the work management server 30 stores the received planned work time periods in the planned work time table (Figure 9) (step S260).

Then, the work management server 30 transmits the data on the planned work time stored in the planned work time table, i.e., the "planned work time zone" and "estimated private room usage time" data, to the usage management server 20 (step S270).

Figure 14 is a flowchart illustrating an example of the processing steps executed by the usage management server 20. The series of processes shown in this flowchart begins when the usage management server 20 receives data regarding the worker's scheduled work time from the work management server 30 (data sent from the work management server 30 in step S270 of Figure 13).

Referring to FIG. 14, the usage management server 20 determines whether it is X minutes before the time period indicated by the "scheduled work time period" based on the data of the scheduled work time received from the work management server 30 (step S310). This "X minutes" is the time indicated in the "estimated private room usage time" received from the work management server 30.

If it is determined that X minutes remain before the scheduled work time (YES in step S310), the usage management server 20 displays a work notification, an example of which is shown in Figure 10, on the display device 15 of the toilet room 10 (step S320).

Next, the usage management server 20 determines whether the "scheduled work time period" received from the work management server 30 has arrived (step S330). When the scheduled work time period arrives (YES in step S330), the usage management server 20 detects whether a user is present in the toilet room 10 based on the detection value of the door opening/closing sensor 12 installed in each stall 11 (step S340).

If it is determined that a user is present in the restroom room 10 (YES in step S340), the usage management server 20 notifies the work management server 30 of this fact (step S350). If it is determined NO in step S340, the usage management server 20 proceeds to step S360 without executing step S350.

Next, the usage management server 20 detects whether there are no users in the toilet room 10 based on the detection value of the door opening/closing sensor 12 (step S360). If it detects that there are no users in the toilet room 10 (YES in step S360), the usage management server 20 notifies the work management server 30 that there are no users in the toilet room 10 (step S370).

Next, the usage management server 20 determines whether a work start notification from the work management server 30 has been received from the worker (step S380). Then, upon receiving the work start notification from the work management server 30, the usage management server 20 displays a "Work in progress" notification, an example of which is shown in FIG. 11, on the display device 15 of the toilet room 10 (step S390).

As described above, in this embodiment, candidate work times are extracted taking into consideration the worker's desired work time and the usage status of the toilet room 10, and the extracted candidate work times are transmitted to the worker's terminal device 40. This allows the worker to check the candidate work times extracted by the work management server 30 on the terminal device 40 and select a desired planned work time period from the extracted candidates. Therefore, according to this embodiment, the worker can perform work in a time period that is close to the worker's desired work time and allows the work to be completed quickly.

In addition, in this embodiment, the display device 15 of the toilet room 10 displays information that a worker will be performing maintenance work during a time period that is the expected cubicle usage time before the scheduled work time. Therefore, people wishing to use the toilet room can be informed that a worker will be performing maintenance work on the toilet room 10 during the scheduled work time period.

In addition, in this embodiment, if a user is detected in the toilet room 10 during the scheduled work time, this is notified to the terminal device 40. This allows the worker to recognize that there is still a user in the toilet room 10 even though it is during the scheduled work time, and to refrain from starting work.

In addition, in this embodiment, if it is detected that there are no users in the toilet room 10 during the scheduled work time period, this fact is notified to the terminal device 40. This allows the worker to recognize that there are no users in the toilet room 10 and begin maintenance work.

In addition, in this embodiment, when a worker begins maintenance work on the toilet room 10, the display device 15 of the toilet room 10 displays a message that maintenance work is in progress. This allows people wishing to use the toilet room 10 to recognize that a worker is performing maintenance work, and to use another toilet room or wait until the maintenance work is completed.

In the above embodiment, the "average private room usage time" used to determine the timing of the display shown in Figure 10 was the "average private room usage time," but it may also be the "average private room usage time" multiplied by a coefficient greater than 1, or may be the time to which a margin of several minutes or 10 minutes is added.

Furthermore, in the above embodiment, the work management server 30 is configured as a server separate from the usage management server 20, but the work management server 30 and the usage management server 20 may also be configured as an integrated unit.

a communication device that acquires a desired time period and a required time for the maintenance work by the worker from a terminal device of the worker;
a processing device that executes a process to adjust the work time based on the desired time period and the required time acquired by the communication device,
The processing device includes:
Calculating a utilization rate and an average utilization time per toilet stall for each predetermined time period based on the utilization time and utilization duration of each stall collected for each of the plurality of stalls;
extracting, from the predetermined time periods, time periods that satisfy first to third conditions as candidates for the work time;
the first condition is that the time difference from the desired time zone is equal to or less than a predetermined time;
the second condition is that the utilization rate is lower than a threshold value;
The third condition is that the time obtained by subtracting the average use time from the length of the predetermined time period is longer than the required time.

This work management device extracts candidate work times based on the worker's desired work time and the availability of restrooms. Based on the extracted candidate work times, the worker can select a time slot that is close to the worker's desired work time and allows the work to be completed quickly, and then carry out the work.

(Appendix 2)
In the work management device according to Supplementary Note 1,
The communication device transmits the extracted candidates for the work time to the terminal device.

This allows workers to check the work time candidates extracted by the work management device on their terminal device and select the desired scheduled work time slot from the extracted candidates.

(Appendix 3)
In the work management device according to Supplementary Note 1 or Supplementary Note 2,
When it is detected that there are no users in the toilet room during the scheduled work time period selected by the worker from the extracted candidate work times, the communication device transmits to the terminal device a message indicating that there are no users in the toilet room.

This allows workers to know that no one is using the toilet room and begin maintenance work.

(Appendix 4)
In the work management device according to any one of Supplementary Note 1 to Supplementary Note 3,
When a user in the toilet room is detected during a scheduled work time period selected by the worker from the extracted candidate work times, the communication device transmits to the terminal device a message indicating that a user is in the toilet room.

This allows workers to know that there are still people using the restroom even during the scheduled work time, and to refrain from starting work.

(Appendix 5)
In the work management device according to any one of Supplementary Note 1 to Supplementary Note 4,
The toilet room is provided with a display device that displays information to a person who wishes to use the toilet room,
The communication device acquires from the terminal device a planned work time period selected by the worker from the extracted work time candidates;
The processing device executes a process for displaying, on the display device, a schedule for carrying out the maintenance work in a time period that is the average usage time before the scheduled work time period.

This allows people wishing to use the restroom to know that maintenance work will be carried out by workers in the restroom during the scheduled work time.

(Appendix 6)
In the work management device according to any one of Supplementary Note 1 to Supplementary Note 5,
the communication device acquires from the terminal device a notification that the worker has started the maintenance work;
When the maintenance work is started, the processing device executes a process for displaying on the display device that the maintenance work is in progress.

This allows people wishing to use a restroom to know that maintenance work is being carried out by workers, and allows them to use another restroom or wait until the maintenance work is completed.
