[0012] In the present disclosure, the "measurement target" is not particularly limited, and may be, for example, a living organism such as a human being, or an object. Specific examples of the measurement target include garbage disposed in a garbage dump, a person waiting at a transportation stop, etc.

[0013] In this disclosure, a "measurement point" refers to, for example, a point where work related to the measurement target is performed. The work may be work performed on the measurement target, or work performed by the measurement target. As a specific example, if the measurement target is garbage, the work is garbage collection, and if the measurement target is a person (passenger) waiting at a bus stop, the work is boarding and disembarking the transportation facility. Specific examples of the measurement point include garbage collection points and transportation stops (bus stops, train stations, etc.).

[0014] The present disclosure can be particularly suitably used, for example, for estimating the amount of garbage (measurement target) collected at each garbage collection point (point) from the total amount collected. However, the present disclosure is not limited thereto, and can also be used, for example, for estimating the number of passengers (measurement target) who boarded at each bus stop (point) from the total number of passengers.

[0015] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. The present disclosure is not limited to the following embodiment. In each of the drawings, the same parts are given the same reference numerals. In addition, the description of each embodiment can be mutually incorporated unless otherwise specified, and the configurations of each embodiment can be combined unless otherwise specified. Can be obtained.

[0016] [Embodiment 1] Fig. 1 is a block diagram showing an example of the configuration of a partial amount estimation support device 10 (hereinafter also referred to as "this device") according to this embodiment. As shown in Fig. 1, this device 10 includes an activity time acquisition unit 11, a total amount acquisition unit 12, a position information acquisition unit 13, an activity time correction unit 14, and a partial amount estimation unit 15. In addition, although not shown, this device 10 may include, for example, an input unit, an output unit, a display unit, and / or a storage unit.

[0017] The device 10 may be, for example, a single device including each of the above-mentioned units, or a device to which each of the above-mentioned units can be connected via a communication line network. The device 10 may be connected to an external device described later via the communication line network. The communication line network is not particularly limited, and a known network may be used, for example, wired or wireless. Examples of the communication line network include an Internet line, a World Wide Web (WWW), a telephone line, a Local Area Network (LAN), a Storage Area Network (SAN), a Delay Tolerant Networking (DTN), a Low Power Wide Area (LPWA), and a Local 5G (L5G). Examples of wireless communication include Wi-Fi (registered trademark), Bluetooth (registered trademark), a Local 5G, and a LPWA. Examples of the wireless communication may include a form in which each device directly communicates with each other (Ad Hoc communication), an infrastructure (infrastructure communication), and an indirect communication via an access point. The device 10 may be incorporated into a server as a system, for example. Furthermore, the present device 10 may be, for example, a personal computer (PC, for example, desktop type or notebook type) in which the program of the present disclosure is installed, a smartphone, a tablet terminal, etc. The present device 10 may be in the form of cloud computing or edge computing, for example, in which at least one of the above-mentioned units is on a server and the other units are on a terminal.

[0018] 2 illustrates a block diagram of a hardware configuration of the present device 10. The present device 10 includes, for example, a central processing unit (CPU, GPU, etc.) 101, a memory 102, a bus 103, a storage device 104, an input device 105, an output device 106, a communication device 107, etc. Each part of the present device 10 is connected to each other via the bus 103 by each interface (I / F).

[0019] The central processing unit 101 cooperates with other components through a controller (such as a system controller or an I / O controller) and controls the entire device 10. In the device 10, the central processing unit 101 executes, for example, the program disclosed herein and other programs, and also reads and writes various information. Specifically, for example, the central processing unit 101 functions as an activity time acquisition unit 11, a total amount acquisition unit 12, a position information acquisition unit 13, an activity time correction unit 14, and a partial amount estimation unit 15. The device 10 may include, as a computing device, other computing devices such as a CPU, a GPU (Graphics Processing Unit), an APU (Accelerated Processing Unit), or a combination of these.

[0020] The bus 103 can also be connected to, for example, an external device. Examples of the external device include a user terminal, an external storage device (external database, etc.), a printer, an external input device, an external display device, an external imaging device, etc. The present device 10 can be connected to an external network (the above-mentioned communication line network) by, for example, a communication device 107 connected to the bus 103, and can also be connected to other devices via the external network.

[0021] An example of the memory 102 is a main memory (primary storage device). When the central processing unit 101 performs processing, the memory 102 reads various operation programs, such as the program of the present disclosure, stored in the storage device 104 described below, and the central processing unit 101 receives data from the memory 102 and executes the program. The main memory is, for example, a RAM (random access memory). The memory 102 may also be, for example, a ROM (read only memory).

[0022] The storage device 104 is also called an auxiliary storage device, for example, in contrast to the main memory (primary storage device). As described above, the storage device 104 stores an operating program including the program of the present disclosure. The storage device 104 may be, for example, a combination of a recording medium and a drive that reads and writes from the recording medium. The recording medium is not particularly limited, and may be, for example, an internal or external type, such as a hard disk (HD), CD-ROM, CD-R, CD-RW, MO, DVD, flash memory, or memory card. The storage device 104 may be, for example, a hard disk drive (HDD) in which the recording medium and the drive are integrated, or a solid state drive (SSD).

[0023] In the present device 10, the memory 102 and the storage device 104 can store various information such as log information, information acquired from an external database (not shown) or an external device, information generated by the present device 10, and information used when the present device 10 executes processing. In this case, the memory 102 and the storage device 104 may store, for example, the above-mentioned information of the user of the present device. Note that at least a part of the information may be stored, for example, in an external server other than the memory 102 and the storage device 104, or may be distributed and stored in a plurality of terminals using blockchain technology or the like. In addition, when the present device 10 includes the storage unit, for example, the memory 102 and the storage device 104 function as the storage unit. The storage unit can store, for example, work time information, total amount, amount of measurement target, total work time, work amount per unit time, worker identification information, worker information, target information, measurement point position information, work reference position information, threshold value, etc.

[0024] The device 10 further includes, for example, an input device 105 and an output device 106. The input device 105 may be, for example, a pointing device such as a touch panel, a track pad, or a mouse; a keyboard; an imaging means such as a camera or a scanner; a card reader such as an IC card reader or a magnetic card reader; and an audio input means such as a microphone. The output device 106 may be, for example, a display device such as an LED display or a liquid crystal display; an audio output device such as a speaker; a printer; or the like. In the first embodiment, the input device 105 and the output device 106 are configured separately, but the input device 105 and the output device 106 may be configured as an integrated device, such as a touch panel display.

[0025] Next, an example of the partial amount estimation support method of this embodiment will be described with reference to the flowchart of Fig. 3. The partial amount estimation support method of this embodiment is implemented as follows, for example, using the device 10 of Fig. 1 or Fig. 2. Note that the partial amount estimation support method of this embodiment is not limited to use of the device 10 of Fig. 1 or Fig. 2.

[0026] The work time acquisition unit 11 acquires work time information for at least one measurement point (S1, work time acquisition step). The work time information is information that links point identification information that identifies the measurement point with work time for work related to the measurement target at the measurement point. The point identification information is, for example, information that identifies the measurement point, and includes information such as the ID, address, and name of the measurement point. When the measurement target is garbage at a garbage collection point, the work time is, for example, the time spent on garbage collection (collection) work at the garbage collection point (measurement point). The work time information may include information on the recording date and time. The recording date and time information is information on the date and time when the work time was recorded at the measurement point (for example, garbage collection date and time). The work time information may include attribute information of the measurement point. The attribute information of the measurement point may be, for example, information on the measurement point (e.g., identification information of a garbage collection site, an address, an area, the type of garbage to be collected, etc.), identification information of a worker at the measurement point (e.g., identification information of a garbage collector), or information on a measurement target at the measurement point (e.g., information on the type of measurement target). The work time acquisition unit 11 may acquire the work time information from, for example, a device that measured the work time (e.g., a terminal of a worker), or may acquire the work time information from a recording medium on which the work time information is recorded. The work time acquisition unit 11 may record the acquired work time information in a memory unit of the present device 10. In this case, the memory unit that records the work time information is also referred to as, for example, a work time memory unit.

[0027] Next, the total amount acquiring unit 12 acquires the total amount of the measurement objects in a predetermined period (S2, total amount acquiring step). The total amount is, for example, information measured on the total amount of the measurement objects present at a plurality of points in a predetermined period. The unit of the total amount is not particularly limited, and may be, for example, the number, the volume, or the weight. The predetermined period is not particularly limited, and may be set appropriately according to, for example, the type of the measurement object and the purpose of use of the present device 10. The predetermined period may be, for example, in hours, days, months, or years. The total amount acquiring unit 12 may acquire the total amount inputted to the input device 105, or may acquire the total amount from an external device via a communication line network. The external device may be, for example, a terminal of a user of the present device 10, a measuring device for the total amount, or the like. The total amount acquiring unit 12 may store the acquired total amount in, for example, the memory 102, the storage device 104, or an external storage device outside the present device 10. In this case, the storage device that stores the total amount is also referred to as a total amount storage unit, for example.

[0028] Next, the position information acquisition unit 13 acquires measurement point position information and work reference position information (S3, position information acquisition step). The measurement point position information is not particularly limited as long as it is information indicating the position of the measurement point, and examples thereof include an address, a GPS (Global Positioning System) information coordinate, and the like. The work reference position information is, for example, information on a reference position at the measurement point where the worker starts work. When the collection target is garbage discarded at a garbage collection site, the measurement point position information is, for example, the address of the garbage collection site, and the work reference position information is, for example, the position information (for example, GPS coordinates) of a garbage collection vehicle. The measurement point position information and the work reference position information may be, for example, recorded in the memory unit of this device 10, or may be recorded in an external storage device outside this device 10.

[0029] The task time correction unit 14 calculates the travel distance at the measurement point from the measurement point position information and the task reference position information (S4A), estimates the travel time at the measurement point based on the travel distance (S4B), and calculates a corrected task time by correcting the task time based on the travel time (S4C) (task time correction process). The task time correction unit 14 can calculate the travel distance by using a known calculation method for the relative distance between two points using, for example, spherical trigonometry. The calculation method for the travel distance is not limited to the method using spherical trigonometry. The task time correction unit 14 can estimate the travel time of the worker at the measurement point by, for example, calculating the travel distance for each of the measurement points and multiplying the calculated travel distance by a predetermined travel speed. The predetermined travel speed is not particularly limited, and can be set to any speed, for example. Specific examples include, but are not limited to, 1 m / s, 2 m / s, 3 m / s, 4 m / s, 5 m / s, 10 m / s, etc. Furthermore, the task time correction unit 14 can calculate a corrected task time by, for example, subtracting the travel time from the task time at the measurement point. The task time correction unit 14 can also subtract the travel time multiple times. This can correct the travel time for, for example, the amount of travel time that the worker takes to travel back and forth.

[0030] The partial amount estimation unit 15 estimates the amount of the measurement object for each measurement point in the predetermined period based on the corrected work time for each measurement point and the total amount (S5, partial amount estimation step). The partial amount estimation unit 15 may estimate the amount of the measurement object for each measurement point by distributing the total amount based on the ratio of the work time for each measurement point, or may estimate the amount of the measurement object for each measurement point based on the work time for each measurement point and the work amount per unit time. Specifically, the partial amount estimation unit 15, for example, first calculates a total corrected work time by summing up the corrected work times for each measurement point in the predetermined period. Next, calculates the work amount per unit time based on the total corrected work time and the total amount. The work amount per unit time can be calculated by dividing the total amount by the total corrected work time. Then, the partial amount estimation unit 15 can estimate the amount of the measurement object at the measurement point by multiplying the corrected work time for each measurement point by the work amount per unit time. The partial amount estimation unit 15 may store the amount of the measurement target at the measurement point in the memory 102, the storage device 104, or an external storage device outside the device 10. In this case, the partial amount estimation unit 15 may store the amount of the measurement target and the point identification information in association with each other. In this case, the storage device that stores the total amount is also referred to as a measurement point amount storage unit, for example.

[0031] The device 10 may, for example, store the estimated amount of the measurement target at the point in a storage unit or output the amount. The output may be, for example, to an output device 106 (e.g., a display) of the device 10 or to an external device outside the device 10.

[0032] A specific example of the use of the device 10 will be described below. In the following description, the measurement target is garbage disposed at a garbage collection point. Also, garbage collection points A, B, and C are taken as examples of the at least one measurement point, and a case will be described in which a user of the device 10 (a collection worker who collects garbage from the garbage collection points) collects garbage from the garbage collection points A, B, and C and estimates the amount of garbage disposed at each of the garbage collection points A, B, and C, but the present disclosure is not limited to the following examples in any way.

[0033] A garbage collector, who is a user of the device 10, collects garbage (measurement target) discarded at at least one garbage collection point (measurement point). At this time, the garbage collection truck is stopped at each garbage collection point, garbage collection work is performed, and the time (work time) until collection is completed is measured, and the measured work time and work time information linked to the identification information of the garbage collection point (point identification information: ID, name, address, etc.) are recorded. Specific examples of the recorded work time information are shown in Table 1 below, but the present disclosure is not limited to the following examples. The record of the work time is not particularly limited, and may be recorded, for example, on a terminal (for example, a smartphone) owned by the garbage collection worker, or may be recorded on an on-board device of the garbage collection truck (for example, a PC, a tablet terminal, etc.). A storage unit that stores a pair (work time information) of the work time and the identification information of the garbage collection point is also called, for example, a work time recording unit. [Table 1]

[0034] Next, the device 10 calculates the distance from the work reference position to the collection point for each collection point ID based on the location information of the collection point and the location information of the garbage collection truck during garbage collection work. The device 10 then calculates a corrected work time for each collection point ID: A, B, C by multiplying the work distance by the worker's movement speed (1 m / s) and subtracting the travel time from the work time. Table 2 below shows specific examples of the corrected work times calculated by the device 10, but the present disclosure is not limited to the following examples. [Table 2]

[0035] Next, the device 10 calculates a total corrected work time (20 seconds + 13 seconds + 67 seconds = 100 seconds) by adding up the corrected work times. Next, the device 10 obtains the total amount (100 kg), and calculates the amount of garbage collected per second (amount of work per unit time) based on the total corrected work time and the total amount (100 kg / 100 seconds = 1 kg / second). Then, the device 10 estimates the amount of garbage collected at each garbage collection point based on the corrected work time at each collection point and the amount of garbage collected per second. Table 3 below shows specific examples of the estimated amount of garbage collected at each garbage collection point, but the present disclosure is not limited to the following examples. [Table 3]

[0036] The device 10 acquires the work time information for collection point IDs: A, B, and C, and adds up the work times at each waste collection point on the same date and time (August 1, 2023) to calculate the total work time (32+17+73=122 seconds).

[0037] After completing collection work at all garbage collection points on the collection route, the worker measures and records the total weight of collected garbage (total amount, for example, 360 kg) at a garbage incineration facility or the like. The device 10 acquires the total amount and calculates the amount of garbage collected per second (amount of work per unit time) based on the total work time and the total amount (360 kg / 122 seconds = 2.951 kg / second). Then, the amount of garbage collected at each garbage collection point is estimated based on the work time at each collection point and the amount of garbage collected per second. Table 4 below shows specific examples of the estimated amount of garbage collected at each garbage collection point, but the present disclosure is not limited to the following examples. [Table 4]

[0038] In the above description, an example is given in which S1 to S5 are executed in sequence, but the present disclosure is not limited to this, and it is sufficient that S1 to S4 are executed upstream of S5, for example. Also, S1 to S4 may be executed simultaneously or sequentially, and in the latter case, the order of execution is arbitrary.

[0039] The partial amount estimation support device of this embodiment, for example, calculates a travel distance at the measurement point from the measurement point position information and work reference position information acquired by a position information acquisition unit, estimates a travel time at the measurement point based on the travel distance, calculates a corrected work time by correcting the work time based on the travel time, and the partial amount estimation unit can estimate the amount of measurement target at each measurement point in the predetermined period based on the corrected work time for each measurement point and the total amount. When estimating the amount of garbage collection from the work time, by subtracting the travel time from the work time, it is possible to suppress the influence of fluctuations in work time that affect the location of a garbage collection site, for example, and to more accurately estimate the amount of garbage collection.

[0040] (Modification) Next, a description will be given of a modified example of the processing of the portion amount estimation support device 10. In the modified portion amount estimation support device 10, for example, when the estimated amount of the measurement target at each measurement point exceeds a threshold, the task time correction unit 14 calculates a corrected travel distance by correcting the travel distance, estimates a corrected travel time based on the corrected travel distance, and calculates a recorrected task time by recalculating the task time based on the corrected travel time, and the portion amount estimation unit 15 re-estimates the amount of the measurement target at each measurement point in the predetermined period based on, for example, the recorrected task time at each measurement point and the total amount.

[0041] In a modified example, the work time correction unit 14 can determine whether the amount of the measurement object for each measurement point estimated in S5 exceeds a threshold value. The threshold value can be set to, for example, an arbitrary value. When the measurement object is garbage discarded in a garbage collection site, the threshold value can be, for example, the amount that a worker can carry in one round trip from the work reference position to the measurement point position information.

[0042] When the task time correction unit 14 determines that the amount of the measurement target exceeds the threshold, it calculates a corrected moving distance by correcting the moving distance. The task time correction unit 14 can calculate the corrected moving distance by, for example, increasing the number of round trips made by the worker for the moving distance. The number of round trips is not particularly limited and may be one, or may be two or more. The task time correction unit 14 can calculate the corrected moving distance by, for example, multiplying the number of round trips n by 2n, the distance from the task reference position to the measurement point position information. Then, the task time correction unit 14 recalculates the task time based on the corrected moving distance to calculate the re-corrected task time. The calculation of the re-corrected task time is the same as that of S4C, except that the corrected moving distance is used instead of the moving distance.

[0043] The partial amount estimation unit 15 re-estimates the amount of the measurement target for each measurement point in the predetermined period, for example, based on the re-corrected operation time for each measurement point and the total amount. The processing of the partial amount estimation unit 15 in the modified example can be performed in the same manner as S5 in the first embodiment, except that the re-corrected operation time is used instead of the operation time or the corrected operation time.

[0044] The modified device 10 can then repeat the processing by the operation time correction unit 14 and the partial amount estimation unit 15 and perform calculations recursively until the amount of the measurement target at each measurement point does not exceed the threshold. This enables estimation that reflects the actual work performed by the worker at each measurement point, and allows more accurate estimation of the amount of the measurement target at each measurement point.

[0045] A specific example will be given to explain the processing of the operation time correction unit 14 and the partial amount estimation unit 15 in the modified example. In the following example, a case will be explained in which the threshold value indicating the set collection amount per round trip by a worker is 50 kg, and the value shown in Table 3 above is calculated as the estimated collection amount. As shown in Table 5 below, the estimated collection amount at collection point ID: C is 67 kg, which exceeds the threshold value of 50 kg. Therefore, the device 10 in the modified example recalculates the estimated collection amount. [Table 5]

[0046] The device 10 calculates a corrected travel distance by gradually increasing the number of round trips made by the worker at the collection point ID: C, where the estimated collection amount exceeds the threshold, from 1, and estimates a corrected travel time based on the corrected travel distance.The device 10 then calculates a total corrected work time by adding up the corrected travel time at collection point ID: C and the work times at collection points ID: A and B, and calculates the amount of garbage collected per second (work amount per unit time) based on the total work time and the total amount (100 kg). Then, recalculation is performed until the estimated collection amount at each collection point meets the threshold value. At this time, the device 10 also recalculates the threshold value based on the number of round trips each time it recalculates (for example, if the threshold value for one round trip is 50 kg, the threshold value for two round trips is 100 kg, the threshold value for three round trips is 150 kg, and so on, increasing the threshold value according to the number of round trips). Table 6 below shows specific examples of the estimated collection amount at each waste collection point after recalculation, but the present disclosure is not limited to the following examples. [Table 6]

[0047] [Embodiment 2] The second embodiment is another example of the portion amount estimation support device of the present disclosure.

[0048] FIG. 4 is a block diagram showing an example of the configuration of the portion amount estimation support device 10A. As shown in FIG. 4, the portion amount estimation support device 10A includes a target information acquisition unit 16 in addition to the configuration of the portion amount estimation support device 10 of the first embodiment. The hardware configuration of the portion amount estimation support device 10A is the same as that of the portion amount estimation support device 10 of FIG. 2, except that the central processing unit 101 has the configuration of the portion amount estimation support device 10A of FIG. 4 instead of the configuration of the portion amount estimation support device 10 of FIG. 1. The processing of the target information acquisition unit 16 will be described below. The processing of the target information acquisition unit 16 can be appropriately inserted at any position in the flowchart of FIG. 3 described in the first embodiment, for example, but is preferably inserted after S5 as shown in FIG. 5.

[0049] First, steps S1 to S5 are carried out in the same manner as steps S1 to S5 in the first embodiment, and the amount of the measurement target at each measurement point is estimated.

[0050] The object information acquiring unit 16 acquires object information including the types of objects contained in the measurement object and their ratios (S11, object information acquiring step). The ratios in the object information are not particularly limited, and any ratio can be set. Furthermore, the object information acquisition unit 16 may further acquire, for example, ratio correction information for correcting the types of objects contained in the measurement target and their ratios for each of the measurement points. The ratio correction information is, for example, information on an index indicating the bias in the amount of the types of objects for each of the measurement points confirmed by the worker.

[0051] The partial amount estimation unit 15 estimates the amount of each type of object for each measurement point based on the estimated amount of the measurement object and the object information (S12, partial amount estimation step). The partial amount estimation unit 15 can estimate the amount of each type of object for each measurement point by, for example, apportioning the estimated amount of the measurement object for each ratio of the types of objects included in the object information and their ratios.

[0052] In the present embodiment, the case where S1 to S5, S11, and S12 are executed in sequence has been described as an example, but the present disclosure is not limited to the above example. In the present disclosure, S1 to S4 may be executed in a process upstream of S5, and S11 and S12 may be executed in a process downstream of S5. S1 to S5 may be executed simultaneously or sequentially, and in the latter case, the execution order is not particularly limited and may be any order.

[0053] When the measurement target is garbage discarded at a garbage collection site, for example, even if the volume of the garbage is the same, the weight differs depending on the specific gravity of the garbage. The partial amount estimation support device of this embodiment can estimate the amount of each type of target at each measurement point based on the target information. Therefore, according to this embodiment, for example, it is also possible to estimate the collected amount of each type of garbage discarded at a garbage collection site.

[0054] [Embodiment 3] The third embodiment is another example of the portion amount estimation support device of the present disclosure.

[0055] FIG. 6 is a block diagram showing an example of the configuration of the portion amount estimation support device 10B. As shown in FIG. 6, the portion amount estimation support device 10B includes an individual worker time correction unit 17 in addition to the configuration of the portion amount estimation support device 10 of the first embodiment. The hardware configuration of the portion amount estimation support device 10B is the same as that of the portion amount estimation support device 10 of FIG. 2, except that the central processing unit 101 has the configuration of the portion amount estimation support device 10B of FIG. 6 instead of the configuration of the portion amount estimation support device 10 of FIG. 1. The process of the individual worker time correction unit 17 will be described below. The process of the individual worker time correction unit 17 can be appropriately inserted at any position in the flowchart of FIG. 3 described in the first embodiment, for example, but is preferably inserted after S4 and before S5 as shown in FIG. 7.

[0056] The task time acquisition unit 11 acquires, for at least one measurement point, the task time information and the worker identification information that identifies the worker at the measurement point in association with each other (S1, task time acquisition step). The worker identification information is not particularly limited as long as it is information that can identify the worker, and examples of the worker identification information include name, nickname, ID, password, email address, telephone number, IP address, MAC address, device specific information of the terminal (serial number of the terminal, identification number such as International Mobile Equipment Identifier, etc.). The worker may be, for example, a single individual or a team including multiple people. Step S1 can be performed in the same manner as S1 in the first embodiment, except that the task time information and the worker identification information are acquired in association with each other.

[0057] Next, steps S2 to S4 are carried out in the same manner as steps S2 to S4 in the first embodiment.

[0058] The worker-specific time correction unit 17 calculates the worker-specific corrected work time by correcting the corrected work time based on the worker information (S21, worker-specific time correction process). The worker information includes information in which the worker identification information is linked to a time correction coefficient. The time correction coefficient is, for example, a coefficient for correcting the work time determined based on the work efficiency of the worker. The time correction coefficient may be, for example, manually set to an arbitrary value, or may be calculated based on the work performance of the worker. When the time correction coefficient is calculated based on the work performance, it can be calculated, for example, by multiple regression analysis using the work time of each worker as an explanatory variable and the amount of work of each worker as an objective variable. Note that the calculation method of the time correction coefficient is not limited to multiple regression analysis, and may be calculated using a known calculation method for an optimization problem, such as linear programming or simulated annealing (SA). The worker information may be, for example, information generated by the present device 10 or information generated outside the present device 10. The worker information may be recorded, for example, in the storage unit of the device 10, or may be recorded in an external storage device outside the device 10. The worker-specific time correction unit 17 can calculate the corrected work time, for example, based on the worker identification information linked to the work time information, by multiplying the work time information by the time correction coefficient calculated based on the work ability as a coefficient.

[0059] The partial amount estimation unit 15 estimates the amount of the measurement target for each measurement point in the predetermined period based on the worker-specific corrected work time for each measurement point and the total amount (S5, partial amount estimation step). Step S5 can be performed in the same manner as S5 in the first embodiment, except that the worker-specific corrected work time is used instead of the corrected work time information.

[0060] A specific example of the use of the device 10 will be described below. In the following description, the measurement target is garbage disposed at a garbage collection point. Also, garbage collection points A, B, and C are taken as examples of the at least one measurement point, and a case will be described in which a user of the device 10 (a collection worker who collects garbage from the garbage collection points) collects garbage from the garbage collection points A, B, and C and estimates the amount of garbage disposed at each of the garbage collection points A, B, and C, but the present disclosure is not limited to the following examples in any way.

[0061] First, using Table 7 below, a specific example of worker information when the collection target is garbage discarded at a garbage collection site will be described. As shown in Table 7 below, information on pairs of work time and total collection amount for each worker identification information is prepared by date. Then, multiple regression analysis is performed with each worker's work time as an explanatory variable and the total collection amount as a response variable to calculate a time correction coefficient. Table 8 below shows the calculated time correction coefficient for each worker (team). [Table 7] [Table 8]

[0062] Next, the device 10B obtains the work time information of the collection points IDs: A, B, and C in association with the worker identification information of each collection point. Then, in the same manner as in the first embodiment, the device calculates the corrected work time information shown in Table 9 below. Next, the device corrects the corrected work time shown in Table 9 below based on the time correction coefficient shown in Table 8. Specifically, the device 10B multiplies the corrected work time of 32 seconds for the garbage collection point A by the time correction coefficient of 1.2 for worker A to calculate the corrected work time for each worker at the garbage collection point A (38.4 seconds). The device 10B multiplies the corrected work time of 17 seconds for the garbage collection point B by the time correction coefficient of 1.2 for worker A to calculate the corrected work time for each worker at the garbage collection point B (20.4 seconds). The device 10B multiplies the corrected work time for garbage collection point C (73 seconds) by the time correction coefficient 1.5 for worker B to calculate the corrected work time for garbage collection point C (109.5 seconds) for each worker. [Table 9]

[0063] Next, the device 10B calculates a total corrected work time (38.4 seconds + 20.4 seconds + 109.5 seconds = 168.3 seconds) by adding up the corrected work times for each worker. The device 10B obtains the total amount (360 kg) and calculates the amount of garbage collected per second (amount of work per unit time) based on the total corrected work time and the total amount (360 kg / 168.3 seconds = 2.139 kg / second). Then, the amount of garbage collected at each garbage collection point is estimated based on the corrected work time for each worker at each collection point and the amount of garbage collected per second. Table 10 below shows specific examples of the estimated amount of garbage collected at each garbage collection point, but the present disclosure is not limited to the following examples. [Table 10]

[0064] In the present embodiment, the case where S1 to S4, S21, and S5 are executed in sequence has been described as an example, but the present disclosure is not limited to the above example. In the present disclosure, S1 to S4 and S21 may be executed in a process upstream of S5. S1 to S4 and S21 may be executed, for example, simultaneously or sequentially, and in the latter case, the order of execution is not particularly limited and may be any order.

[0065] The partial amount estimation support device of this embodiment can, for example, correct the acquired work time based on worker information by the work time correction unit, and estimate the amount of the measurement object for each measurement point based on the corrected work time for each measurement point and the total amount. When the measurement object is garbage discarded at a garbage collection site, for example, the garbage collection time (work time) increases in correlation with the amount of garbage. On the other hand, when the work time is measured by each of multiple workers, even if the amount of garbage is the same, the collection time differs depending on the collection efficiency of the worker. According to the partial amount estimation support device of this embodiment, for example, the work time can be corrected by a time correction coefficient determined based on the work efficiency of the worker, so that the influence of the variation in the work time of each worker can be suppressed, and the amount of the measurement object for each measurement point can be easily estimated with higher accuracy.

[0066] [Embodiment 4] The program of this embodiment is a program for causing a computer to execute each step of the partial amount estimation support method described above. Specifically, the program of this embodiment is a program for causing a computer to execute a task time acquisition procedure, a total amount acquisition procedure, a position information acquisition procedure, a task time correction procedure, and a partial amount estimation procedure.

[0067] The task time acquisition step includes acquiring task time information for at least one measurement point, The work time information is information in which point identification information for identifying the measurement point is associated with work time for a work related to a measurement target at the measurement point, the total amount acquisition step acquires a total amount of the measurement target in a predetermined period of time; The position information acquisition step acquires measurement point position information and work reference position information, The operation time correction procedure includes: Calculating a travel distance at the measurement point from the measurement point position information and the work reference position information, and estimating a travel time at the measurement point based on the travel distance; Calculating a corrected task time by correcting the task time based on the travel time; The partial amount estimation step estimates the amount of the measurement target at each of the measurement points in the predetermined period based on the corrected operation time at each of the measurement points and the total amount.

[0068] The program of this embodiment can also be said to be a program that causes a computer to function as an activity time acquisition procedure, a total amount acquisition procedure, a position information acquisition procedure, an activity time correction procedure, and a partial amount estimation procedure.

[Industrial Applicability]

[0072] According to the present disclosure, the amount of the measurement object for each measurement point in a predetermined period can be estimated based on the work time information for at least one measurement point acquired by the work time acquisition unit and the total amount of the measurement object for a predetermined period acquired by the total amount acquisition unit.
