Abstract
Description
[Technical Field]
[0001] The present disclosure relates to a work assignment method and a work assignment system. [Background technology]
[0002] In building facility management work, the daily tasks are divided among the people on duty that day. These tasks include daily inspections, responding to sudden alarms and malfunctions, and responding to requests and complaints from building users. In all cases, the main tasks involve physical activity.
[0003] For example, daily inspection work involves walking to the installation locations of each piece of equipment scattered around the site and carrying out the inspection while bending and stooping. Inspecting electrical equipment and rotating machinery is dangerous and requires tense work. Heavy manholes may also be opened. In such situations, if all of a worker's working hours are allocated to this task, fatigue increases the likelihood of mistakes or personal injury, so it is necessary to allocate work to individuals in a way that does not tire them out.
[0004] Patent document 1 describes a method of inputting the constraint rate, which is the time a worker is confined to a designated work area relative to the total working time, the total time worked, and the number of steps the worker takes, and then calculating the worker's level of fatigue based on a predetermined calculation formula that includes these input data. [Prior art documents] [Patent documents]
[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-010157 Summary of the Invention [Problem to be solved by the invention]
[0006] The method described in Patent Document 1 calculates the degree of fatigue from the constraint rate, work time, and the number of steps the worker takes, and is therefore unable to adequately calculate the degree of fatigue of workers performing building facility management work.
[0007] Therefore, an object of the present disclosure is to provide a work allocation method and a work allocation system that can allocate work to workers in building facility management work so that the workers do not become too fatigued. [Means for solving the problem]
[0008] The work allocation method disclosed herein includes the steps of preparing a first table that defines the amount of work for each facility management task within a building, including the number of steps taken by the worker, the worker's stress time, and the number of times the worker performs physical work, and the steps of allocating multiple facility management tasks within the building for one day to each worker by referring to the first table.
[0009] The work allocation system of the present disclosure includes a memory unit that stores a first table that defines the workload for each facility management task within a building, including the number of steps taken by the worker, the worker's stress time, and the number of times the worker performs physical work, and a processor that allocates multiple facility management tasks within the building to each worker for one day based on the first table. [Effects of the Invention]
[0010] According to the present disclosure, work can be appropriately assigned to workers in building facility management tasks so as not to increase their fatigue level, thereby reducing the possibility of work errors and accidents occurring. [Brief explanation of the drawings]

Modes for Carrying Out the Invention
[0012] Hereinafter, embodiments will be described with reference to the drawings. Embodiment 1. FIG. 1 is a diagram showing the configuration of the work assignment system of Embodiment 1.
[0013] The work assignment system includes a work manager terminal 10 and a work assignment server 20. The work manager terminal 10 includes an input device 11, a communication device 12, a display device 13, a memory 14, and a processor 15. The communication device 21 executes communication with the communication device 21 of the work assignment server 20.
[0014] The display device 13 displays the contents of the work assignment table and the workload table by worker stored in the memory 14.
[0015] The memory 14 stores the work assignment table and the workload table by worker transmitted from the work assignment server 20. The memory 14 further stores a program executed by the processor 15. The processor 15 executes the program stored in the memory 14.
[0016] The work assignment server 20 includes a communication device 21, a memory 22, and a processor 23. The communication device 21 executes communication with the communication device 12 of the work management terminal 10.
[0017] The memory 22 stores a work amount table, a work amount upper limit table, a work assignment table, and a work amount table by worker. The memory 22 further stores a program executed by the processor 23. The processor 23 executes the program stored in the memory 22.
[0018] In the present embodiment, the work in the building management work is decomposed into elements causing fatigue, and the work is assigned to each worker so that each element does not exceed the upper limit (the amount at which fatigue is felt).
[0019] The inventor of the present application has found that the elements causing fatigue of the work in the building management work are the number of walking steps, the tension time, and the number of heavy work operations. The tension time means the time for performing work with a high possibility of physical danger such as falling, electric shock, being pinched, etc. while paying attention. Heavy work means work that requires momentary muscle strength not used in daily life and involves an operation that causes muscle fatigue later.
[0020] FIG. 2 is a diagram showing the walking route of the monthly electrical inspection. FIG. 3 is a diagram showing the number of steps of the monthly electrical inspection. The worker is waiting at the disaster prevention center. In the monthly electrical inspection, the worker alternately executes movement and inspection work of electrical equipment. The movement is in a short time and the number of steps increases during the movement. The inspection of electrical equipment is in a long time and the number of steps decreases during the inspection of electrical equipment. FIG. 4 is a diagram showing the work amount F1 of the monthly electrical inspection. In the electrical inspection, there is a risk of electric shock, so it is accompanied by tension. Also, although the heavy work operation is set to 0 here, if there is an electrical cable laid underground, it is necessary to lift the manhole. In such a case, the number of heavy work operations will not be 0.
[0021] Figure 5 is an elevation view of the walking route for in-building temperature rounds. Figure 6 is a plan view of the walking route for in-building temperature rounds. Figure 7 is a diagram showing the number of steps for in-building temperature rounds. For in-building temperature rounds, the operator walks for about 40 seconds and stops for about 15 seconds to measure the temperature, and repeats this. When moving between floors, since an escalator is used, the number of steps is reduced. Figure 8 is a diagram showing the workload F2 for in-building temperature rounds.
[0022] Figure 9 is a diagram showing the walking route for exhaust fan inspection. Figure 10 is a diagram showing the number of steps for exhaust fan inspection. For exhaust fan inspection, the operator moves from the disaster prevention center to the rooftop and visually inspects or checks for abnormal noises the exhaust fans scattered on the rooftop. When moving from the disaster prevention center to the rooftop and when moving from the rooftop to the disaster prevention center, the number of steps of the operator increases. During inspection, the number of steps decreases. Figure 11 is a diagram showing the workload F3 for exhaust fan inspection. For exhaust fan inspection, it is necessary to be careful not to get the hand caught by the fan or belt, so it is accompanied by tension.
[0023] Figure 12 is a diagram showing the walking route for water volume count value confirmation. Figure 13 is a diagram showing the number of steps for water volume count value confirmation. For water volume count value confirmation, the operator moves from the disaster prevention center to the location where the water meter is installed, reads and records the value of the water meter, and repeats this. Figure 14 is a diagram showing the workload F4 for water volume count value confirmation.
[0024] Figure 15 is a diagram showing the walking route for escalator startup. Figure 16 is a diagram showing the number of steps for escalator startup. For escalator startup, the operator starts from the disaster prevention center, performs the startup operation of the escalator, and moves to the next escalator. When moving from the disaster prevention center to the installation location of the west escalator group, when moving from the installation location of the west escalator group to the installation location of the east escalator group, and when moving from the installation location of the east escalator group to the disaster prevention center, the number of steps of the operator increases. While sequentially starting the west escalators and while sequentially starting the east elevators, the number of steps of the operator decreases. Figure 17 is a diagram showing the workload F5 for escalator startup.
[0025] The processor 23 of the work allocation server 20 prepares a work amount table that defines the work amount for each facility management task within a building, including the number of steps taken by the worker, the worker's stress time, and the number of times the worker performs physical work. FIG. 18 is a diagram illustrating a workload table according to the first embodiment.
[0026] The workload table defines the number of steps taken by the worker, the amount of stress time, and the number of times the worker performs physical labor for each facility management task within a building. Chemical solution replenishment in Figure 18 involves replenishing chlorine to be added to tap water in an underground tank, which involves lifting a manhole. Residual chlorine measurement involves sampling tap water and measuring the residual chlorine.
[0027] The processor 23 prepares a workload upper limit table that defines the upper limit of the workload of one worker per day. FIG. 19 is a diagram illustrating a workload upper limit table according to the first embodiment.
[0028] The workload limit table defines the upper limit of workload for each worker per day. For example, the upper limit of the number of steps per day may be set to 12,000 (steps), the upper limit of stress time per day may be set to 120 (minutes), and the upper limit of the number of strenuous work steps per day may be set to 5 (times).
[0029] The processor 23 refers to the workload table and the workload upper limit table, and assigns multiple tasks to each worker so that the workload of each worker in a day does not exceed the upper limit. The processor 23 creates a task assignment table that defines the workers to whom each task is assigned. FIG. 20 is a diagram illustrating a task assignment table according to the first embodiment.
[0030] The work assignment table indicates, for each facility management task in a building on a specified day, the worker in charge, the number of steps taken by the worker, the worker's stress time, and the number of times the worker performs heavy work.
[0031] The processor 23 creates a workload table for each worker that determines the workload of one or more tasks assigned to each worker. FIG. 21 is a diagram showing the workload table for each worker according to the first embodiment.
[0032] The workload table for each worker represents the workload (number of steps, stress time, number of heavy work levels) for each worker on a specified day.
[0033] FIG. 22 is a flowchart showing the operation procedure of the work assignment system according to the first embodiment.
[0034] In step S101, in the work assignment server 20, the processor 23 prepares a workload table as shown in FIG. 18 and stores it in the memory 22. The processor 23 may obtain the workload table from the outside, or may create the workload table based on the input of the user of the work assignment server 20.
[0035] In step S102, in the work assignment server 20, the processor 23 prepares an upper limit table of workload as shown in FIG. 19 and stores it in the memory 22. The processor 23 may obtain the upper limit table of workload from the outside, or may create the upper limit table of workload based on the input of the user of the work assignment server 20.
[0036] In step S103, in the work management terminal 10, the work manager inputs a work assignment request through the input device 11.
[0037] In step S104, in the work management terminal 10, the processor 15 transmits a work assignment request signal including the work names of a plurality of work contents on the specified day and the worker names of a plurality of workers on that day through the communication device 12.
[0038] In step S105, in the work assignment server 20, the processor 23 receives a work assignment request signal through the communication device 21, and stores in the memory 22 the work names of the multiple work contents on the designated date and the names of the multiple workers on that day.
[0039] In step S106, in the work assignment server 20, the processor 23 refers to the work names of the multiple work contents on the designated date, the names of the multiple workers on that day, the work volume table as shown in FIG. 18, and the upper limit table of work volume as shown in FIG. 19 stored in the memory 22, and assigns work to each worker so that the upper limit of the daily work volume of each worker is not exceeded.
[0040] In step S107, in the work assignment server 20, the processor 23 creates a work assignment table as shown in FIG. 20 based on the work assignment result, and stores it in the memory 22.
[0041] In step S108, in the work assignment server 20, the processor 23 creates a work volume table for each worker as shown in FIG. 21 based on the work assignment result, and stores it in the memory 22.
[0042] In step S109, in the work assignment server 20, the processor 23 transmits a work assignment response signal including the work assignment table and the work volume table for each worker to the work management terminal 10 through the communication device 21.
[0043] In step S109, in the work management terminal 10, the processor 15 receives the work assignment response signal through the communication device 12.
[0044] In step S109, in the work management terminal 10, the processor 15 displays the work assignment result and the work volume for each worker on the display device 13 based on the work assignment table and the work volume table for each worker.
[0045] According to this embodiment, the daily work load can be divided by taking into consideration the fatigue-causing factors such as the number of steps, the amount of stress, and the number of times manual labor is performed, thereby reducing the possibility of work errors and workplace accidents caused by excessive work. Embodiment 2 In the second embodiment, the upper limit of the amount of work per day differs for each worker. FIG. 23 is a diagram illustrating a workload upper limit table according to the second embodiment.
[0046] Workers A, B, and C have different upper limits on the number of steps they can take per day, different hours of stress per day, and different numbers of times they perform physical work per day. A variation of the second embodiment.
[0047] In a variation of the second embodiment, the upper limit of the amount of work per day varies depending on the group to which the worker belongs. The group may be determined taking into consideration experience, age, sex, physique, and the like. FIG. 24 is a diagram illustrating a workload upper limit table according to a modification of the second embodiment.
[0048] Groups 1, 2, and 3 differed in the upper limit of the number of steps per day, the amount of stress time per day, and the number of times of physical exertion per day. Embodiment 3 FIG. 25 is a diagram illustrating a workload table according to the third embodiment.
[0049] The workload table of the third embodiment includes a workload index in addition to the items in the workload table of the first embodiment. The workload index R is expressed as a weighted sum of the number of steps, stress time, and number of times of force work, as shown in the following formula. R=W1×X1+W2×X2+W3×X3...(1)
[0050] X1, X2, and X3 are the number of steps, the stress time, and the number of force works. W1, W2, and W3 are the weights.
[0051] FIG. 26 is a diagram showing the work assignment table of Embodiment 3. The work assignment table of Embodiment 3 includes a work amount index in addition to the items of the work assignment table of Embodiment 1.
[0052] FIG. 27 is a diagram showing the work amount table for each worker of Embodiment 3. The work amount table for each worker of Embodiment 3 includes a work amount index in addition to the items of the work amount table for each worker of Embodiment 1.
[0053] FIG. 28 is a flowchart showing the operation procedure of the work assignment system of Embodiment 3. The difference between the flowchart of Embodiment 3 and the flowchart of Embodiment 1 is that the flowchart of Embodiment 3 does not include step S102 and includes steps S206 to S209 instead of steps S106 to S109.
[0054] In step S206, in the work assignment server 20, the processor 23 refers to the work amount table as shown in FIG. 25 and assigns a plurality of tasks to each worker so that the variation in the work amount of each worker is minimized. For example, the processor 23 may assign a plurality of tasks to each worker so that the variance or standard deviation of the work amount index R of each worker is minimized.
[0055] In step S207, in the work assignment server 20, the processor 23 creates a work assignment table as shown in FIG. 26 based on the work assignment result and stores it in the memory 22.
[0056] In step S208, in the work assignment server 20, the processor 23 creates a work amount table for each worker as shown in FIG. 27 based on the work assignment result and stores it in the memory 22.
[0057] In step S209, in the work assignment server 20, the processor 23 transmits a work assignment response signal including the work assignment table and the worker-specific work amount table to the work manager terminal 10 via the communication device 21.
