The present disclosure relates to a work support system, a work support method, and a work support program for giving work support.
Maintenance work performed by a plurality of workers, such as regular inspection work for plant equipment, requires a huge amount of work to be done within a limited work period while ensuring work quality. In such maintenance work, the work quality is likely to be influenced by a skill level of a worker. In recent years, however, it has become difficult to secure a skilled worker. In addition, there are increasing demands for cost cuts due to longer maintenance periods (intervals) and shorter work periods, and it is required to meet these demands.
In order to meet these demands, it has been proposed to give work support by managing the schedule of the huge amount of work included in the maintenance work with arithmetic processing by an electronic computation device such as a computer. For example, Patent Document 1 discloses a system for giving work support such that each worker involved in maintenance work acquires information about work contents distributed to each worker at an appropriate timing, by displaying maintenance work procedure information indicating a maintenance work procedure on a terminal based on scheduled work schedule information.
Patent Document 1: JP2003-233419A
Meanwhile, in the process of executing a work schedule related to the maintenance work as in Patent Document 1, an interruption event may occur in the work contents distributed to each worker. If the interruption event thus occurs in some works, it becomes difficult to perform another work that presupposes the concerned work (for example, work that belongs to a common critical path and is performed later in chronological order). In this case, the worker distributed to the another work has no choice but to wait until the work in which the interruption event occurs is restored, resulting in waste.
At least one embodiment of the present disclosure has been made in view of the above, and the purpose of the at least one embodiment of the present disclosure is to provide a work support system, a work support method, and a work support program capable of giving efficient work support even if the interruption event occurs in the middle of the work.
A work support system according to at least one embodiment of the present disclosure is a work support system that gives work support by using a work schedule which is created by dividing at least one support target work into a plurality of division tasks with a unit work amount corresponding to a worker unit including a plurality of workers, and distributing the worker unit to each of the plurality of division tasks, the work support system including an interruption information acquisition part configured to acquire interruption information indicating that an interruption event occurs in any of the plurality of division tasks, and a work schedule modification part configured to modify the work schedule by redistributing, to the division task started after the interruption event, the remaining worker unit excluding the worker unit distributed to the division task in which the interruption event occurs, if the interruption information acquisition part acquires the interruption information.
A work support method according to at least one embodiment of the present disclosure is a work support method that gives work support by using a work schedule which is created by dividing at least one support target work into a plurality of division tasks with a unit work amount corresponding to a worker unit including a plurality of workers, and distributing the worker unit to each of the plurality of division tasks, the work support method including a step of acquiring, by an interruption information acquisition part, interruption information indicating that an interruption event occurs in any of the plurality of division tasks, and a step of modifying, by a work schedule modification part, the work schedule by redistributing, to the division task started after the interruption event, the remaining worker unit excluding the worker unit distributed to the division task in which the interruption event occurs, if the interruption information acquisition part acquires the interruption information.
A work support program according to at least one embodiment of the present disclosure causes, in order to give work support by using a work schedule which is created by dividing at least one support target work into a plurality of division tasks with a unit work amount corresponding to a worker unit including a plurality of workers, and distributing the worker unit to each of the plurality of division tasks, a computer to function as a means for acquiring interruption information indicating that an interruption event occurs in any of the plurality of division tasks, and a means for modifying the work schedule by redistributing, to the division task started after the interruption event, the remaining worker unit excluding the worker unit distributed to the division task in which the interruption event occurs, if the interruption information is acquired.
According to at least one embodiment of the present disclosure, it is possible to provide a work support system, a work support method, and a work support program capable of giving efficient work support even if an interruption event occurs in the middle of work.
Embodiments of the present invention will now be described with reference to the accompanying drawings. It is intended, however, that unless particularly specified, dimensions, materials, shapes, relative positions and the like of components described in the embodiments shall be interpreted as illustrative only and not intended to limit the scope of the present invention unless particularly specified.
As shown in
The main server 4 is a server for performing main information processing in the work support system 1. The main server 4 creates work support information by performing predetermined information processing with information acquired from the data server 6, the input terminal 8, and the user terminals 10a and 10b, and provides the work support information to the user terminals 10a and 10b, thereby giving work support to a worker using the user terminals 10a and 10b.
The data server 6 is a server that includes a database for storing various types of data related to an operation of the work support system 1. The data server 6 is configured to store and read various types of information by being accessed from other system components via the communication network 2. The data server 6 includes a plurality of databases corresponding to the respective types of information, and
The input terminal 8 is an input interface for inputting the various types of information about the operation of the work support system 1. The input terminal 8 may be a human interface that can manually be input by an operator such as the worker, or may be an inter-device interface that can input data from another information processing device.
The user terminals 10a and 10b are, respectively, devices that can be used by the worker who is the implementing entity of the support target work. The work support information created by the main server 4 is output to the user terminals 10a and 10b to allow the worker to use the work support information. In the present embodiment, it is configured such that the work support information is displayed on the respective displays of the user terminals 10a and 10b to be used by the worker. However, an output form of the work support information on the user terminals 10a and 10b is not limited to the above configuration. In addition to outputting the work support information, the user terminals 10a and 10b may be configured to allow the worker to view a calculation result of the main server 4 and the various types of information stored in the data server 6 as needed.
The user terminals 10a and 10b may be configured to function not only as a means for providing the work support information and the like to the worker but also as an input interface for the worker to input various types of information to the work support system 1 as needed. In this case, the information input from the user terminals 10a and 10b may be processed by the user terminals 10a and 10b themselves, or may be sent to the main server 4 to be processed or may be stored in the data server 6 via the communication network 2.
The main server 4 has a hardware configuration constituted by an electronic computation device such as a computer, and is configured by installing a work support program according to at least one embodiment of the present disclosure on the hardware configuration. Thus, the main server 4 can perform the work support method according to at least one embodiment of the present disclosure. The main server 4 includes a work schedule creation part 12, a work schedule modification part 14, a division task completion information acquisition part 16, an interruption information acquisition part 18, a work support information creation part 20, a worker identification information acquisition part 22, and an output part 24. The respective blocks constituting the main server 4 may be integrated or further divided.
The work schedule creation part 12 creates a work schedule WS based on the various types of information stored in the data server 6. More specifically, the work schedule creation part 12 acquires information about a worker unit from the worker unit database 6a and information about the division task from the division task database 6b, and creates the work schedule WS based on these pieces of information.
The worker unit database 6a stores information about the worker unit composed of the workers who are, respectively, the implementing entities of the support target work. The worker unit includes the number of workers each corresponding to a unit work amount of each division task obtained by dividing the support target work. In the present embodiment, the number of worker units involved in the support target work and the number of workers included in each worker unit are optimized, making it possible to contribute to ensuring work quality and shortening a work period.
The number of worker units U under the supervision of one Foreman F may be set optionally. In the present embodiment, a case where five worker units A to E are placed is exemplified for the reasons to be described below. Depending on the scale of the support target work, the organizational structure may be made such that a plurality of Foremen F are placed and the plurality of worker units U are placed under the supervision of the respective Foremen F.
Returning to
In the present embodiment, the number of workers who communicate with each other upon executing the work in each worker unit as described above is set to “3” based on the reason to be described below, thereby building a good communication system in which occurrence of miscommunication is prevented.
As shown in
In addition to the above-mentioned three workers (the unit leader UL and the unit members UM1, UM2), the worker unit may include a helper H that can devotedly act for these workers. The helper H has the role of acting according to one-sided instruction from the workers and unlike the above-mentioned three workers, does not require mutual communication upon executing the work. In the example of
At a work site, the work is performed with the unit leader UL, the unit members UM1, UM2, and the helpers H, who hierarchically constitute the worker unit, being mixed. Thus, at the work site, each person may wear bibs for level discrimination so that each hierarchy (level) can be discriminated. As the bibs, it is possible to use a visually clear object, such as an object which is color coded according to the level.
Such information about the worker unit may artificially be created in advance or may be created by computer calculation. In the latter case, the information can be created by inputting a basic worker list to the computation device unit such as a computer and classifying the workers into each worker unit based on predetermined conditions. Then, the information about these worker units may be stored in the worker unit database 6a and prepared in advance, or may be input by using the input terminal 8.
Subsequently, the division task database 6b stores information about the division task created by dividing the support target work. The division task is created by dividing the support target work so as to correspond to the unit work amount of the worker unit. The information about the division task includes a plurality of division tasks thus created and relation information between the plurality of division tasks. The former is information about specific work contents in each division task, and includes, for example, information about work procedures, a caution in each work procedure, and a tool used in each work procedure. Further, the latter is information about the relative relationship between the respective division tasks, and includes, for example, information about a master-slave relationship and a critical path between the respective division tasks.
The work schedule creation part 12 creates the work schedule WS based on the information about the worker unit and the information about the division task described above.
These series of division tasks T1, T2, . . . are specified based on the information about the division task. More specifically, the master-slave relationship and the critical path of the respective division tasks T1, T2, . . . are defined based on the above-mentioned relation information. In
The plurality of worker units A to E are distributed to the division tasks T1, T2, . . . . The worker units A to E are equivalent to each other, and are distributed to the division tasks T1, T2, . . . in order according to a priority set in advance. The priority set for each of the division tasks T1, T2, . . . may be stored in the division task database 6b in advance, for example.
The work schedule WS is thus created by distributing the plurality of worker units A to E to the plurality of division tasks T1, T2, . . . . Then, the work schedule WS created by the work schedule creation part 12 is stored in the work schedule database 6c of the data server 6 via the communication network 2, for example.
In the present embodiment, one support target work is basically handled. However, if a plurality of support target works are handled, a plurality of work schedules WS may also be created to correspond to the plurality of support target works, respectively. In this case, the information about the division task and the information about the worker unit included in the data server 6 are also managed in association with each support target work.
The work schedule modification part 14 is configured to modify the work schedule WS. For example, the work schedule modification part 14 accesses the work schedule database 6c triggered by an input of a predetermined signal, and modifies the work schedule WS stored in the work schedule database 6c. In the present embodiment, the work schedule WS is modified if the division task completion information acquisition part 16 acquires division task completion information or the interruption information acquisition part 18 acquires interruption information.
The division task completion information acquisition part 16 acquires the division task completion information. If any one of the plurality of division tasks T1, T2, . . . is completed, the division task completion information is input to the main server 4 as a signal indicating the above-described completion. For example, if the specific division task is completed, the division task completion information is created by operating the user terminal 10a or 10b, and is input to the main server 4 via the communication network 2. Then, the work schedule modification part 14 modifies the work schedule WS by redistributing the worker unit to the remaining division task excluding the division task specified from the division task completion information. Thus, the work schedule WS is updated every time each division task is completed, allowing for efficient work schedule management according to the progress of the work.
The division task completion information may include work history information about the completed division task. In this case, the work history information is saved as a work history in the data server 6 to be used for work evaluation and the like.
If an interruption event Y occurs in any one of the plurality of division tasks T1, T2, . . . , the interruption information acquisition part 18 is input to the main server 4 as a signal indicating the above-described occurrence. The interruption event Y broadly includes the reason why the worker unit has no choice but to interrupt execution of the division task when executing the division task, and means, for example, an event which is difficult to be completed within a work time assumed in advance for completing the division task. To give a specific example, in a case where a division task includes the process of removing a bolt securing a certain part in order to inspect the part, if the bolt is stuck and thus is difficult to be removed by normal procedures, this corresponds to the interruption event Y.
For example, such interruption information is created by operating the user terminal 10a or 10b by the worker in the occurrence of the interruption event Y, and is sent to the main server 4 via the communication network 2, thereby being acquired by the interruption information acquisition part 18.
With reference to
First, the work schedule modification part 14 determines whether the interruption information acquisition part 18 acquires the interruption information (step S100). By repeatedly performing the determination in step S100, the occurrence of the interruption event Y is monitored. In the present embodiment, as shown in
If the interruption information acquisition part 18 acquires the interruption information (step S100: YES), the work schedule modification part 14 accesses the work schedule database 6c of the data server 6 and acquires the current work schedule WS (see
Subsequently, the work schedule modification part 14 modifies the work schedule WS by redistributing the worker unit to the division task started after the interruption event (step S102). The modification of the work schedule WS in step S102 is performed by redistributing, to the division task started after the interruption event, the remaining worker unit excluding the worker unit distributed to the division task in which the interruption event occurs. In the example of
In the modified work schedule WS' shown in
Alternatively, the modification of the work schedule WS in step S102 may be performed by distributing the worker unit, which is distributed to the division task included in the critical path to which the division task where the interruption event Y occurs belongs and started after the interruption event, to the division task which is included in the critical path different from the critical path of the division task where the interruption event Y occurs and is started after the interruption event. In the example of
In the work schedule WS before the modification shown in
The division task to which the worker unit is redistributed may be executed ahead of schedule according to the time allowance of the worker unit. In the example of
Subsequently, the work schedule modification part 14 stores the modified work schedule WS′ in the work schedule database 6c (step S103). Thus, the work schedule WS stored in the work schedule database 6c is updated to the latest state.
If the work support system 1 handles the plurality of support target works as described above, the work schedule modification part 14 may modify the plurality of work schedules respectively corresponding to the support target works. In this case, the worker unit may be redistributed to the division task over a plurality of work schedules. Thus, if the interruption event occurs in any of the division tasks, each work schedule is modified by redistributing the worker unit to the division task in each work schedule, making it possible to utilize the human resources more effectively.
Returning to
The work support information creation part 20 may create useful work support information for the worker who is specified based on the worker identification information acquired by the worker identification information acquisition part 22. The worker identification information acquisition part 22 acquires the worker identification information for identifying the worker. For example, each worker owns a worker identification device capable of outputting the worker identification information for specifying an individual, and the worker identification information acquisition part 22 acquires, via the communication network 2, the worker identification information output from the device. As the worker identification device, it is possible to use, for example, an ID card owned by each worker and having an RFID tag capable of transmitting the worker identification information, a barcode capable of reading the worker identification information, or the like. The user terminal 10a or 10b acquires the worker identification information from these devices and sends the acquired worker identification information to the main server 4 via the communication network 2.
The work support information creation part 20 specifies, based on the thus acquired worker identification information, the worker who is the destination of the work support information, and creates the work support information for the specified worker. Thus, it is possible to provide the work support information customized for each worker. Further, the worker may be able to refer to work support information for other workers and the various types of information stored in the data server 6 via the user terminals 10a and 10b, by operating the user terminals 10a and 10b.
The output part 24 outputs the work support information created by the work support information creation part 20 to the user terminals 10a and 10b. Thus, based on the work schedule WS stored in the work schedule database 6c, the work support information about each division task is output to each worker.
The output part 24 may output the work support information on the condition that the worker identification information acquisition part detects the specific worker identification information. For example, the work support information for the worker unit A is output on the condition that the worker identification information corresponding to each worker constituting the worker unit A is acquired. Thus, since the work support information is output after recognizing the worker to whom the work support information is provided, the situation where the worker misses the work support information is systematically avoided, making it possible to effectively improve work quality.
Next, some specific examples of the work support information will be described.
In the example of
Further, in the example of
The specific example of the cautionary point M7 included in the work support information will now be described. Herein, as an example of the division task, assembly work of a pipe 30 inside of which a fluid flows in a given direction will be described. As shown in
Therefore, the work support information displays, as the cautionary point M7, the direction N of the fluid in the pipe 30 which is the work target on the display of the user terminal 10b. Thus, the worker can easily and accurately grasp the direction N of the fluid in the pipe 30 by checking the display, and it is possible to effectively prevent a work mistake such as the wrong direction of the orifice 36.
Returning to
The work support information may also include information about the tool used in the division task.
Each shelf 40a of the storage shelf 40 may be provided with a display 46 such as a photograph or a name of the tool 42 on the surface of each shelf 40a so that the stored tool 42 can be determined.
As shown in
Further, which tool 42 is stored in which storage shelf 40 may be determined according to the frequency of use and the weight of each tool 42. For example, the frequently used tool 42 and the tool 42 which is heavy and requires a large amount of labor for transportation may be stored in the storage shelf 40 located near the reference position O of the worker.
Further, as a device for outputting the tool identification information from each tool 42, an RFID tag capable of transmitting a signal related to the tool identification information may be used. In this case, by attaching the RFID tag to each tool 42 and acquiring the tool identification information transmitted from each tool 42, which tool 42 is stored in which storage shelf 40 may be managed. Furthermore, based on the storage state of the tool 42 in each storage shelf 40, a tool collection route TR for efficiently collecting each tool 42 required in each division task T1, T2, . . . to which the worker unit is distributed may be included in the work support information.
As described above, according to the above-described embodiments, it is possible to provide the work support system, the work support method, and the work support program capable of giving efficient work support by effectively utilizing the limited resources even if the interruption event occurs in the middle of execution of the work.
As for the rest, without departing from the spirit of the present disclosure, it is possible to replace the constituent elements in the above-described embodiments with known constituent elements, respectively, as needed and further, the above-described embodiments may be combined as needed.
The contents described in the above embodiments would be understood as follows, for instance.
(1) A work support system (1) according to an embodiment of the present disclosure is a work support system that gives work support by using a work schedule (such as the work schedule WS of the above-described embodiment) which is created by dividing at least one support target work into a plurality of division tasks (such as the division tasks T1, T2, . . . of the above-described embodiment) with a unit work amount corresponding to a worker unit (such as the worker units A to E of the above-described embodiment) including a plurality of workers, and distributing the worker unit to each of the plurality of division tasks, the work support system including an interruption information acquisition part (such as the interruption information acquisition part 18 of the above-described embodiment) configured to acquire interruption information indicating that an interruption event (such as the interruption event Y of the above-described embodiment) occurs in any of the plurality of division tasks, and a work schedule modification part (such as the work schedule modification part 14 of the above-described embodiment) configured to modify the work schedule by redistributing, to the division task started after the interruption event, the remaining worker unit excluding the worker unit distributed to the division task in which the interruption event occurs, if the interruption information acquisition part acquires the interruption information.
With the above configuration (1), the work schedule is created by dividing the support target work into the plurality of division tasks having the unit work amount and distributing the worker unit to each of the plurality of division tasks. In such work schedule, if the interruption event occurs in any of the division tasks, the work schedule is modified by redistributing, to the division task started after the interruption event, the remaining worker unit excluding the worker unit distributed to the division task in which the interruption event occurs. Thus, even if the interruption event occurs in some of the division tasks, it is possible to construct the work schedule that efficiently utilizes the worker unit distributed to another division task.
(2) In some embodiments, in the above configuration (1), the work schedule modification part modifies the work schedule to distribute the worker unit, which is distributed to the division task included in a critical path to which the division task where the interruption event occurs belongs and started after the interruption event, to the division task which is included in a critical path different from the critical path of the division task where the interruption event occurs and is started after the interruption event.
With the above configuration (2), the worker unit distributed to the division task which is difficult to start due to the occurrence of the interruption event is redistributed to the division task belonging to the critical path different from the critical path of the division task in which the interruption event occurs. Thus, it is possible to assign the worker unit which may have wasted waiting time due to the occurrence of the interruption event to the division task which is not affected by the interruption event, and to reconstruct the work schedule capable of efficiently utilizing the human resources.
(3) In some embodiments, in the above configuration (1) or (2), the support work system further includes a division task completion information acquisition part (such as the division task completion information acquisition part 16 of the above-described embodiment) for acquiring division task completion information indicating that any of the plurality of division tasks is completed. The work schedule modification part is configured to modify the work schedule by redistributing the worker unit to the remaining division task, if the division task completion information acquisition part acquires the division task completion information.
With the above configuration (3), if some of the division tasks are completed, the worker unit is redistributed to the uncompleted division task. Thus, the work schedule is updated every time each division task is completed, allowing for efficient work schedule management according to the progress of the work.
(4) In some embodiments, in any one of the above configurations (1) to (3), the at least one support target work includes a plurality of support target works independent of each other, and the work schedule modification part is configured to modify a plurality of work schedules corresponding to the plurality of support target works, respectively.
With the above configuration (4), if there are the plurality of support target works, the work schedule is created for each support target work by distributing the worker unit to the division task obtained by dividing the plurality of support target works. Then, if the interruption event occurs in any of the division tasks, each work schedule is modified by redistributing the worker unit to the division task in each work schedule, making it possible to utilize the human resources more effectively.
(5) In some embodiments, in any one of the above configurations (1) to (4), the support work system further includes an output part (such as the output part 24 of the above-described embodiment) configured to output work support information about the division task based on the work schedule.
With the above configuration (5), since the work support information based on the work schedule is output, it is possible to give efficient work support to each worker performing the work in accordance with the work schedule.
(6) In some embodiments, in the above configuration (5), the work support information includes information about at least one of a tool used in the division task, the worker unit, and a work caution.
With the above configuration (6), since the above information is included in the work support information, it is possible to give effective work support.
(7) In some embodiments, in the above configuration (6), the division task includes installation work for an orifice (such as the orifice 36 of the above-described embodiment) which is disposed between a pair of pipe members (such as the pipe members 32, 34 of the above-described embodiment) in correspondence with a direction of a fluid (such as the direction N of the fluid of the above-described embodiment) flowing inside the pair of pipe members, and the work caution includes information about an installation direction of the orifice.
With the above configuration (7), since the work caution included in the work support information includes the information about the installation direction of the orifice, it is possible to effectively prevent the worker from mistaking the installation direction of the orifice in the orifice installation work.
(8) In some embodiments, in any one of the above configurations (5) to (7), the support work system further includes a worker identification information acquisition part (such as the worker identification information acquisition part 22 of the above-described embodiment) configured to acquire worker identification information for identifying the worker. The output part is configured to output the work support information, if the worker identification information acquisition part acquires the worker identification information, which corresponds to the work support information, corresponding to the worker unit.
With the above configuration (8), the work support information is output on the condition that the worker identification information corresponding to the specific worker is acquired. Thus, it is possible to accurately provide the work support information to the specific worker, making it possible to give higher-quality work support.
(9) In some embodiments, in any one of the above configurations (5) to (8), the information about the used tool includes information about a shortest route (TR) passing through a plurality of storage shelves (such as the storage shelves 40 of the above-described embodiment) in which a plurality of tools (such as the tools 42 of the above-described embodiment) used in the division task are stored, respectively.
With the above configuration (9), the work support information includes the route for collecting the tool required in the division task. If the plurality of tools are respectively stored in the plurality of storage shelves, for example, by providing the shortest route passing through the plurality of storage shelves as the work support information, the worker can collect the tool by the most efficient route.
(10) A work support method according to an embodiment of the present disclosure is a work support method that gives work support by using a work schedule (such as the work schedule WS of the above-described embodiment) which is created by dividing at least one support target work into a plurality of division tasks (such as the division tasks T1, T2, . . . of the above-described embodiment) with a unit work amount corresponding to a worker unit (such as the worker units A to E of the above-described embodiment) including a plurality of workers, and distributing the worker unit to each of the plurality of division tasks, the work support method including a step (such as step S100 of the above-described embodiment) of acquiring, by an interruption information acquisition part (such as the interruption information acquisition part 18 of the above-described embodiment), interruption information indicating that an interruption event (such as the interruption event Y of the above-described embodiment) occurs in any of the plurality of division tasks, and a step (such as step S102 of the above-described embodiment) of modifying, by a work schedule modification part (such as the work schedule modification part 14 of the above-described embodiment), the work schedule by redistributing, to the division task started after the interruption event, the remaining worker unit excluding the worker unit distributed to the division task in which the interruption event occurs, if the interruption information acquisition part acquires the interruption information.
With the above method (10), the work schedule is created by dividing the support target work into the plurality of division tasks having the unit work amount and distributing the worker unit to each of the plurality of division tasks. In such work schedule, if the interruption event occurs in any of the division tasks, the work schedule is modified by redistributing, to the division task started after the interruption event, the remaining worker unit excluding the worker unit distributed to the division task in which the interruption event occurs. Thus, even if the interruption event occurs in some of the division tasks, it is possible to construct the work schedule that efficiently utilizes the worker unit distributed to another division task.
(11) A work support program according to an embodiment of the present disclosure causes, in order to give work support by using a work schedule (such as the work schedule WS of the above-described embodiment) which is created by dividing at least one support target work into a plurality of division tasks (such as the division tasks T1, T2, . . . of the above-described embodiment) with a unit work amount corresponding to a worker unit (such as the worker units A to E of the above-described embodiment) including a plurality of workers, and distributing the worker unit to each of the plurality of division tasks, a computer to function as a means (such as the interruption information acquisition part 18 of the above-described embodiment) for acquiring interruption information indicating that an interruption event occurs in any of the plurality of division tasks, and a means (such as the work schedule modification part 14 of the above-described embodiment) for modifying the work schedule by redistributing, to the division task started after the interruption event, the remaining worker unit excluding the worker unit distributed to the division task in which the interruption event occurs, if the interruption information is acquired.
With the above program (11), the work schedule is created by dividing the support target work into the plurality of division tasks having the unit work amount and distributing the worker unit to each of the plurality of division tasks. In such work schedule, if the interruption event occurs in any of the division tasks, the work schedule is modified by redistributing, to the division task started after the interruption event, the remaining worker unit excluding the worker unit distributed to the division task in which the interruption event occurs. Thus, even if the interruption event occurs in some of the division tasks, it is possible to construct the work schedule that efficiently utilizes the worker unit distributed to another division task.
