(Outline of this embodiment)
(1) A worker assignment method according to the present disclosure is a worker assignment method that assigns workers to work that occurs in a board production facility that produces boards, wherein when one or more of the above-mentioned works occur, each of the above-mentioned a creation step of creating a work plan representing the worker to be assigned to each work and the work order of each work based on the position of the worker and the proficiency level of each worker with respect to the work that has occurred; include.

Conventionally, when one or more operations occur in a circuit board production facility that produces circuit boards, it is necessary to manage the operators (or operators), such as which operator performs which operation and in what order the multiple operations are to be carried out. (administrator) made a decision and responded. However, since the judgment was made by the worker, the judgment was not necessarily made appropriately, and it sometimes took a long time to complete all the work.

According to the worker assignment method described above, a work plan is created that indicates the worker to be assigned to each work and the order of work for each work, based on the position of each worker and the proficiency level of each worker with respect to the work that has occurred. do. For this reason, according to the above-described worker assignment method, workers can be assigned so that all the work occurring in the board production equipment can be completed in a short time, compared to the case where the worker (or manager) decides to respond. can.

(2) In the creation process, a plurality of work plans with different workers assigned to the work are created, and the worker assignment method is selected from among the plurality of work plans created in the creation process. A transmitting step of transmitting the work plan that completes all the work earliest to a predetermined destination may be included.

According to the worker assignment method described above, a plurality of work plans with different workers assigned to the work are created, and the work plan that completes all the work that occurred the earliest among the created work plans is specified as a predetermined work plan. Since it will be sent to the destination, it is more likely that all the work that has occurred will be completed in a short time.

(3) In the creation step, the work plan is created from the viewpoint of shortening the movement time for the worker to move to the work position of the work, and the work plan is created from the viewpoint of shortening the work time of each work. may

The above-mentioned "predetermined destination" may be, for example, a mobile terminal carried by the worker, or an e-mail address of the worker. The transmission destination of the work plan is not limited to the mobile terminal of the worker, and may be the terminal device used by the manager who manages the work or the e-mail address of the manager.
According to the above worker assignment method, all work can be completed in a short time compared to creating a work plan that considers only travel time or work time. become more sexual.

(4) The circuit board production equipment has a plurality of production lines for producing the circuit boards, and each worker is assigned the production line to be in charge of, and the worker assignment method is such that each worker is assigned the work a first receiving step for receiving a setting as to whether to assign only the work of the production line that the worker is in charge of, or to also assign the work other than the production line that the worker is in charge of; If only the work on the line is set to be assigned, each worker is assigned only the work on the production line that the worker is in charge of, and the work other than the production line that the worker is in charge of is also set to be assigned. If there is, the work other than the production line in charge may be assigned.

According to the above worker assignment method, there is more freedom in assigning work compared to the case where only the work that occurred on the production line in charge is assigned or the work other than the production line in charge is also assigned. degree improves.

(5) The circuit board production equipment has a plurality of production lines for producing the circuit boards, and the worker assignment method includes a second receiving step of receiving designation of one of the plurality of production lines. and when a new work occurs on the production line specified in the second reception process while each worker is performing the work according to the work plan, in the creation process, the specified A work plan may be recreated in which the new work is assigned to the worker performing the work outside the production line.

According to the above worker assignment method, the work that occurred on the specified production line is assigned to the worker who is doing the work other than the specified production line, so the work that occurred on the specified production line can be terminated with

(6) In the creation process, the current work of the worker who is performing the work other than the designated production line may be interrupted and the new work interrupted.

According to the above worker allocation method, the current work of workers who are doing work outside the designated production line is interrupted and new work is interrupted. can be completed in a short time.

(7) In the creation process, the new work is interrupted after the current work of the worker who is performing the work other than the designated production line and before the next work of the worker. You can let

According to the worker assignment method described above, after the current work of a worker who is doing work that occurred outside the designated production line, and before the next work of that worker, a new work is interrupted. The work that occurred on the designated production line can be completed in a short time.

(8) including a third receiving step of receiving a setting as to whether or not to give priority to training for allocating the work with priority to the worker having a low proficiency level for the work, wherein the setting is made to give priority to training; If so, in the creation process, the worker with a relatively low proficiency level for the work may be preferentially assigned to the work that has occurred.

According to the worker assignment method described above, when there is a worker whose proficiency in a certain work is low, by assigning the worker to the work, the worker's proficiency in the work can be improved. can be done.

(9) including a fourth receiving step of receiving a setting as to whether or not to conduct extra-time education; may be preferentially assigned to the worker with a relatively low proficiency level for the work that has occurred, within the range where is completed.

If there is a worker with a low proficiency level for a certain task, and the worker is assigned to the task for training, all the tasks will not be completed within the target time due to the low proficiency level of the task. there is a possibility. If all the work is not completed within the target time, the board production equipment may stop and the productivity may decrease.
According to the worker assignment method described above, workers can be educated within a range in which the time required to complete all tasks does not exceed the target time, so it is possible to educate workers while suppressing a decrease in productivity.

(10) including a fifth receiving step of receiving a setting as to whether or not to subdivide the generated work and allocate it to a plurality of workers; If the number of workers is greater than the number of works, one work may be subdivided and a plurality of workers may be assigned in the creation process.

According to the worker assignment method described above, when the number of workers is greater than the number of works, by subdividing one work and allocating a plurality of workers, it is possible to shorten the time required to complete the work.

(11) A first method for notifying a predetermined notification destination of the necessity of training the worker for the work when the work time for the work performed by the worker is longer than the standard work time for the work. may include a notification step of

If the working time of a worker for a certain work is longer than the standard working time, it can be said that the worker is low in proficiency in the work and needs training.
According to the worker assignment method described above, for example, if a terminal of a manager who manages workers is set as a predetermined notification destination, the manager can determine which worker needs training for which task. become easier.

(12) The method may include a second notification step of notifying a predetermined notification destination of the fact that the allowable work time has been exceeded when the actual work time of the work exceeds the allowable work time.

If the actual work time of a certain worker exceeds the allowable time, there is a possibility that the board production equipment will stop due to the work delay.
According to the above worker assignment method, for example, if the terminal of the manager who manages the worker is set as a predetermined notification destination, the manager instructs other workers to help with the work that exceeds the allowable time. By doing so, delays in work can be suppressed.

(13) For each worker, the method may include an update step of updating the proficiency level of the work based on at least one of the cumulative work time of the work and the cumulative work count of the work for each work.

According to the worker assignment method described above, since the proficiency levels of workers can be automatically updated, the burden on the manager can be reduced compared to when the manager who manages the workers updates the proficiency levels manually.

<Embodiment 1>
Embodiment 1 will be described with reference to FIGS. 1 to 14. FIG. In the following description, the reference numerals in the drawings may be omitted except for some of the same components.

(1) Substrate Production Equipment A substrate production equipment 2 according to the first embodiment will be described with reference to FIG. The substrate production facility 2 includes two production lines L (production lines L1 and L2) for producing substrates. Each production line L includes a loader 11, a screen printer 12, a print inspection machine 13, a dispenser 14, and three surface mounters M (M11, M12, M13 for production line L1, M21, M22 for production line L2). , M23), a post-mounting visual inspection machine 15, a reflow device 16, a post-curing visual inspection machine 17, and an unloader 18, which are connected in series via a plurality of conveyors 19.

Each production line L is assigned with one worker (worker A for the production line L1, worker B for the production line L2) who is in charge of the work of the production line L. The number of workers assigned to one production line L may be two or more.
Each worker carries a portable terminal 30 (an example of a predetermined destination) such as a mobile phone or a tablet computer. A mobile terminal 30 is wirelessly connected to a communication network 33 via an access point 32 . The mobile terminal 30 includes a position detection sensor (for example, a GPS sensor) that receives radio waves transmitted from a satellite positioning system such as GPS (Global Positioning System) and detects the position of the mobile terminal 30 (in other words, the position of the worker). ing. The method of detecting the position of the mobile terminal 30 is not limited to this, and other methods may be used.

A manager terminal 31 (an example of a predetermined notification destination) is a terminal of a manager who manages each worker. The administrator terminal 31 may be a so-called personal computer, or may be a mobile terminal such as a mobile phone or a tablet computer.
A worker allocation device 1 (an example of a computer) is a device that allocates workers to work that occurs on a production line L. FIG.
Each device constituting the production line L, the mobile terminal 30 , the manager terminal 31 and the worker assignment device 1 are communicably connected via a communication network 33 .

(2) Work that occurs in the production line In the production line L, various types of work occur. For example, in the case of the screen printer 12, there are tasks such as replenishing solder paste to be printed on the board and coping with any errors in the screen printer 12. FIG. For example, when the amount of solder paste decreases to a predetermined amount, the screen printer 12 notifies the operator assignment device 1 that a solder paste replenishment operation has occurred. Even when some error occurs, the worker assignment device 1 is notified that work for coping with the error has occurred.

In the case of the dispenser 14, the work of replenishing the adhesive, the work of coping with some error of the dispenser 14, and the like occur. In the case of the surface mounter M, the work of replacing the reel around which the component tape holding the component is wound, the work of coping with some error of the surface mounter M, and the like occur.

In order to facilitate understanding, in the following description, the work that occurs in the surface mounter M will be taken as an example. Various errors occur in the surface mounter M. In the following description, an error related to the mounting head provided in the surface mounter M will be described as an example. A surface mounter M picks up a component supplied from a component tape, a component tray, or the like by a mounting head, moves the mounting head picking up the component to a mounting position on the board, and mounts the component on the board. In that case, there will be an error where component pickup fails (hereinafter referred to as a pickup error), an error where a component drops while the mounting head that is picking up the component is being moved (hereinafter called a component drop error), and an An error occurs in which the component is not mounted on the board and the mounting head picks up the component and returns to the position of the component tape or the component tray (hereinafter referred to as component return error).

(3) Electrical Configuration of Worker Assignment Device The electrical configuration of the worker assignment device 1 will be described with reference to FIG. The worker assignment device 1 is a so-called personal computer, and includes a control section 40, a storage section 41, a communication section 42 (an example of an acquisition section), a display section 43, an operation section 44, and the like.
The control unit 40 includes a CPU 40A, a RAM 40B, and the like. The storage unit 41 is a storage device including a nonvolatile storage medium such as a hard disk. The storage unit 41 stores various programs such as a worker allocation program for allocating workers to work occurring on the production line L, and various data described later. The control unit 40 controls each unit of the worker assignment device 1 by executing programs stored in the storage unit 41 . The communication unit 42 is a communication circuit for the worker assignment device 1 to communicate with other devices such as the mobile terminal 30 . The control unit 40 receives (an example of acquisition) position information from each mobile terminal 30 via the communication unit 42 . The display unit 43 is a display device such as a liquid crystal display. The operation unit 44 is an input device such as a keyboard, mouse, and touch panel.

(4) Various data stored in the storage section Various data stored in the storage section 41 include a proficiency level table, a work time table, a standard/permissible work time table, and each Location information representing the location of the device and the like are included. The proficiency level table, work time table, and standard/permissible work time table will be described below with reference to Tables 1 to 3.

Table 1 is an example of a proficiency level table. In the proficiency level table, the proficiency level of each worker is associated with each task. Proficiency is evaluated on a scale of 0 to 3. 0 is the lowest proficiency and 3 is the highest proficiency. The working time of each work becomes shorter as the worker's proficiency level increases.

Table 2 is an example of a work time table. The work time table records the actual work time of each work for each worker and for each work. Work hours are recorded for each work. Specifically, for example, the worker operates the mobile terminal 30 to notify the worker assignment apparatus 1 of the start of work when starting work, and operates the mobile terminal 30 to end the work when the work is finished. Notice. The worker assignment device 1 records the time from when the start of work is notified to when the end of work is notified as work time in the work time table.

Table 3 is an example of a standard/permissible work time table. The standard/allowable work time table associates the standard work time and the allowable work time for each work. The standard work time is the standard work time for the work count of the work. The standard working time becomes shorter as the number of operations increases. The allowable work time is the time allowed as work time for each work. If the work time exceeds the allowable work time, even if the board production equipment 2 does not immediately stop, the board production equipment 2 may stop as it is.

(5) Processing Executed by Worker Assignment Device The following processing executed by the worker assignment device 1 will be described.
・Work plan creation and transmission processing ・Training necessity notification processing ・Work delay notification processing ・Proficiency level update processing

(5-1) Work Plan Creation and Transmission Processing When one or more tasks occur in the board production equipment 2, the worker assignment device 1 determines the position of each worker and the proficiency level of each worker for the task that has occurred. Based on the above, a work plan representing the workers to be assigned to each work and the work order of each work is created, and the created work plan is transmitted to each worker's mobile terminal 30 (an example of a predetermined destination).

Specifically, the worker assignment device 1 creates a work plan from the viewpoint of shortening the movement time for the worker to move to the work position, and a work plan from the viewpoint of shortening the work time of each work. Send the work plan that completes all the work that occurred the earliest among the work plans. The work plan from the viewpoint of shortening the travel time and the work plan from the viewpoint of shortening the work time are examples of a plurality of work plans in which different workers are assigned to the work. A specific description will be given below.

(5-1-1) Setting of How to Create a Work Plan Setting of how to create a work plan will be described with reference to FIG. The worker assignment device 1 displays on the display unit 43 a setting screen for accepting settings for how to create a work plan. The administrator who manages the workers sets the method of creating the work plan on the displayed setting screen.

For the setting of how to create a work plan, the setting for the production line (an example of the first reception process and the second reception process), the setting for the proficiency level (the third reception process and the fourth reception process) There are three setting items: one example), and a setting for work subdivision (an example of the fifth reception process).
In the setting of the production line, any one of "all lines", "only lines in charge", "designated line priority (with interruption)" and "designation line priority (without interruption)" is selected. When "prioritize designated line (with interruption)" and "prioritize designated line (without interruption)" are selected, the preferential production line L is also designated. In the following description, the specified production line L will be referred to as the specified line.

"All Lines" is a setting that allocates to each worker also the work that occurred on production lines L other than the production line L that the worker is in charge of.
"Only the line in charge" is a setting that assigns to each worker only the work that occurred in the production line L that the worker is in charge of.

"Designated line priority (with interruption)" and "Designated line priority (no interruption)" are when new work occurs on the designated line while each worker is working according to the work plan. This is the setting for assigning the work done by the worker who is doing the work that occurred on the production line L other than the designated line (hereinafter referred to as the non-designated line). The worker assignment device 1 recreates a work plan in which newly generated work is assigned and transmits it to the workers.

With interruption is a setting that interrupts the work that the worker is currently doing and assigns the work that has newly occurred on the designated line to the worker that is doing the work that has occurred on the non-designated line. In this case, the worker who is performing the work that occurred on the non-designated line interrupts the current work and gives priority to the work that newly occurred on the designated line. After completing the new work on the designated line, the worker resumes the interrupted work. That is, when there is an interrupt, the work newly generated on the designated line is prioritized over the work currently being performed by the worker who is performing the work generated on the non-designated line.

No interruption does not interrupt the work currently being done by the worker who is doing the work that occurred on the non-designated line, but the work that the worker who is doing the work that occurred on the non-designated line is not interrupted. It is a setting that interrupts new work that occurred on the specified line before the work of . In other words, when there is no interruption, the work newly generated on the designated line is prioritized over the next work of the worker who is performing the work generated on the non-designated line.

In setting the proficiency level, one of "proficiency level priority", "education priority", and "surplus time education" is selected.
"Proficiency Priority" is a setting in which, when assigning a worker to a task that has occurred, a worker with a relatively high level of proficiency in the task is preferentially assigned.
"Education priority" means that when assigning a worker to a task that has occurred, a worker with a lower proficiency in that task than other workers (in other words, a worker with a relatively low proficiency in ) are assigned with priority.
“Surplus time education” is a system where when the time to complete all the work that has occurred is shorter than the target time (i.e., when there is surplus time before the target time), This is a setting for allocating a worker whose proficiency level of the work is lower than that of the workers of (in other words, a worker whose work proficiency level is relatively low). In other words, "surplus time education" is a setting to educate workers only when there is surplus time.

Either one of "work subdivision" and "do not subdivide work" is selected in the setting of work subdivision.
"Subdivide work" is when the number of workers is greater than the number of tasks that have occurred (in other words, when the number of workers has room), one task is subdivided into multiple workers. It is a setting to share with. "Do not subdivide work" is a setting that does not subdivide work. If "do not subdivide work" is selected, one worker is assigned to one work.

(5-1-2) Example of creating a work plan An example of creating a work plan will be described below.

(Creation example 1)
Creation example 1 is an example in which "all lines" are selected as the setting for the production line L, "preferred skill level" is selected as the setting for the proficiency level, and "do not subdivide the work" is selected as the setting for the subdivision of work.
As shown in FIG. 4, in Example 1, the reel change of the surface mounter M11 on the production line L1, the adsorption error of the surface mounter M22 of the production line L2, and the adsorption error of the surface mounter M23 of the production line L2 occurred almost simultaneously. are doing.

I will explain how to create a work plan from the viewpoint of shortening the travel time. Since the closer the distance between the worker's current position and the work position is, the shorter the travel time is, the worker assignment device 1 determines the position of the mobile terminal 30 from the worker's mobile terminal 30 (in other words, the worker's position). position information representing the position of the worker, and preferentially assigns to the worker work that occurred at a position close to the worker's position.

Specifically, in the example shown in FIG. 4, the worker A on the production line L1 is near the surface mounter M11 on the production line L1. assign. Since the worker B on the production line L2 is near the surface mounter M23 on the production line L2, the worker assignment device 1 assigns the worker B to deal with the pickup error of the surface mounter M23.

In the example shown in FIG. 4, the work assigned to worker A (exchange of reels of surface mounter M11 on production line L1) is the work assigned to worker B (suction error of surface mounter M23 on production line L2). countermeasure) is assumed to be shorter than the processing time. Here, the processing time is the total time of travel time and work time. In this case, the worker assignment device 1 assigns the worker A whose work has been completed first to the position of the worker A (that is, the position near the surface mounter M11) that is closest to the worker A among the tasks that have not yet been assigned to the worker. Assign work that occurs in close proximity. However, in the example shown in FIG. 4, there is only one remaining task (only the handling of the adsorption error of the surface mounter M22 on the production line L2). A countermeasure for the pick-up error of the mounter M22 is assigned.

A work plan 50 shown in FIG. 5 shows a work plan from the viewpoint of shortening the travel time. As shown in FIG. 5, in the work plan 50, the worker A on the production line L1 is instructed to replace the reel of the surface mounter M11 on the production line L1 and to deal with the adsorption error of the surface mounter M22 on the production line L2 in this order. Worker B on the production line L2 is assigned to deal with the pickup error of the surface mounter M23 on the production line L2.
The movement time for replacing the reel of the surface mounter M11 assigned to the worker A on the production line L1 in the work plan 50 is the movement from the position of the worker A to the surface mounter M11 when one or more tasks occur. It's time. The travel time for dealing with the pickup error of the surface mounter M22 assigned to worker A is the travel time from the surface mounter M11 to the surface mounter M22. That is, the travel time for each task varies depending on where the worker was prior to the task.

Creation of a work plan from the viewpoint of shortening work time will be described with reference to FIG. Since the higher the proficiency level, the shorter the work time, in the work plan from the viewpoint of shortening the work time, the worker assignment device 1 assigns each work to a work whose proficiency level is higher than that of other workers. Workers (in other words, workers with relatively high proficiency) are preferentially assigned. Specifically, as shown in Table 1, since the worker A on the production line L1 has a relatively high degree of proficiency in dealing with the pickup error, the worker assignment device 1 assigns the worker A to the surface mounter on the production line L2. Allocate action for pick-up error of M22. Here, in the example shown in FIG. 4, as the handling of the adsorption error, there are two handlings of the adsorption error of the surface mounter M22 of the production line L2 and the handling of the adsorption error of the surface mounter M23 of the production line L2. In this case, the worker assignment device 1 allocates the handling of the adsorption error that occurred at a position close to the current position of the worker A among these two handling of the adsorption error in order to shorten the movement time. On the other hand, as shown in Table 1, since the worker B has a relatively high degree of proficiency in reel replacement, the worker assignment device 1 assigns the worker B to replace the reels of the surface mounter M11 on the production line L1.

In the example shown in FIG. 4, the work assigned to worker A on production line L1 (coping with a pickup error that occurred in surface mounter M22 on production line L2) is the work assigned to worker B on production line L2 ( It is assumed that the processing time (=moving time + working time) is shorter than the reel replacement of the surface mounter M11 on the production line L1. In this case, the worker assignment device 1 assigns to the worker A who finishes the work first, the work with the high proficiency level of the worker A among the tasks that have not yet been assigned to the worker. However, in the example shown in FIG. 4, since there is only one remaining work (only dealing with the adsorption error of the surface mounter M23 on the production line L2), the worker assignment device 1 does not depend on the skill level of the worker A. A countermeasure for the pickup error of the surface mounter M23 on the production line L2 is assigned.

A work plan 51 shown in FIG. 5 is a work plan created from the viewpoint of shortening the work time. As shown in the work plan 51, the worker A on the production line L1 must deal with the pick-up error of the surface mounter M22 on the production line L2 and the pick-up error of the surface mounter M23 on the production line L2 in this order. The worker B is assigned to replace the reels of the surface mounter M11 on the production line L1. Since the worker B is far from the surface mounter M11 on the production line L1, the travel time for reel replacement is longer than in the work plan from the viewpoint of shortening the travel time.

As can be seen from FIG. 5, in creation example 1, the work plan 51 from the viewpoint of shortening the work time completes all the work earlier than the work plan 50 from the viewpoint of shortening the travel time. Therefore, the worker assignment device 1 transmits to workers A and B a work plan from the viewpoint of shortening the work time.
In creation example 1, the work plan with the viewpoint of shortening the work time ends earlier than the work plan with the viewpoint of shortening the travel time, but depending on how the work occurs, the work plan with the viewpoint of shortening the travel time is better. All the work may be completed earlier than the work plan from the viewpoint of shortening the work time. In that case, the worker assignment device 1 transmits a work plan from the viewpoint of shortening the travel time.

(Creation example 2)
Creation example 2 is an example in which "only assigned line" is selected as the production line setting, "proficiency level priority" is selected as the proficiency level setting, and "no work subdivision" is selected as the work subdivision setting.

FIG. 6 is an example of the work that has occurred. In the example shown in FIG. 6, a reel exchange and a suction error occur on the production line L1, and a reel exchange occurs on the production line L2. In this case, the worker assignment device 1 assigns to each worker only the work of the production line L that the worker is in charge of.
Here, the worker A on the production line L1 will be described as an example. A work plan 52 shown in FIG. 7 is a work plan from the viewpoint of shortening the travel time of worker A. In FIG. In creating the work plan 52 from the viewpoint of shortening the travel time, the worker assignment device 1 first assigns the reel exchange of the surface mounter M11 of the production line L1, which is the work near the current position of the worker A, and then the surface mounter M11. Allocate the handling of the pick-up error of the mounter M12. A work plan 53 shown in FIG. 7 is a work plan from the viewpoint of shortening the work time for worker A. In FIG. In creating the work plan 53 from the viewpoint of shortening the work time, the worker assignment device 1 first assigns the worker A to deal with the pickup error of the surface mounter M12 of the production line L1, and then the reel of the surface mounter M11. Allocate exchanges.

In the case of creation example 2, the work plan 53 from the viewpoint of shortening the work time takes a long time for worker A to first move to the surface mounter M12. However, all the work that occurs is finished early. Therefore, the worker assignment device 1 transmits to the worker A the work plan 52 from the viewpoint of shortening the travel time. The same applies to worker B.

(Creation example 3)
Creation example 3 is an example in which "specified line priority (with interruption)" is selected as the production line setting, "proficiency level priority" is selected as the proficiency level setting, and "do not subdivide work" is selected as the work subdivision setting. is. In creation example 3, it is assumed that the production line L1 is specified as the specified line.

As shown in FIG. 8A, worker A is performing work W1 on production line L1 (designated line) according to the transmitted work plan 55, and worker B is performing work W1 on production line L2 (non-designated line) according to the transmitted work plan 55. line) is being performed.
In the example shown in FIG. 8A , a new work W3 occurs on the production line L1 (designated line) at time T1 while each worker is performing work according to the work plan 55 . In this case, as shown in FIG. 8B, the worker assignment device 1 assigns a new work W3 occurring on the production line L1 to the worker B (that is, the worker who is working on the non-designated line). 56 is recreated and sent to worker A and worker B. Specifically, the worker assignment device 1 interrupts the work W2 currently being performed by the worker B on the production line L2 to interrupt the work W3 that has newly occurred on the production line L1.

(Creation example 4)
Creation example 4 is an example in which "specified line priority (no interruption)" is selected as the production line setting, "proficiency level priority" is selected as the proficiency level setting, and "do not subdivide work" is selected as the work subdivision setting. is. It is also assumed that the production line L1 is specified as the specified line in creation example 4 as well.

In the work plan 57 shown in FIG. 9A, a new work W4 occurs on the production line L1 at time T1. In this case, the worker assignment device 1 assigns the new work W4 generated on the production line L1 to the next work W2 currently performed by the worker B on the production line L2, as in the work plan 58 shown in FIG. 9B. Interrupt before work W3.

(Creation example 5)
Creation example 5 is an example in which "all lines" are selected as the production line setting, "education priority" is selected as the proficiency level setting, and "no work subdivision" is selected as the work subdivision setting.

FIG. 10 is an example of the work that has occurred. In the example shown in FIG. 10, the surface mounter M11 on the production line L1 has a reel exchange, the surface mounter M12 has a suction error, and the surface mounter M23 on the production line L2 has a reel exchange.
A work plan 59 shown in FIG. 11 indicates a work plan giving priority to education. As shown in Table 1 described above, the worker A on the production line L1 has a lower proficiency in reel replacement than in dealing with suction errors. For this reason, the worker assignment device 1 assigns the worker A to replace the reels of the surface mounter M11 and the surface mounter M23 in order to improve the worker A's proficiency in dealing with the pick-up error. More specifically, in order to shorten the travel time, the worker assignment device 1 first assigns the reel replacement of the surface mounter M11, which is a task near the current position of the worker A on the production line L1, and then Allocate reel replacement for the surface mounter M23. On the other hand, as shown in Table 1, since the worker B of the production line L2 has a lower proficiency in dealing with pickup errors than reel replacement, the worker assignment device 1 instructs the worker B to deal with the pickup error of the surface mounter M12. Assign an action.

(Creation example 6)
Creation example 6 is an example in which "all lines" are selected as the production line setting, "surplus time education" is selected as the proficiency level setting, and "no work subdivision" is selected as the work subdivision setting.
For example, assume that the surface mounter M11 on the production line L1 has a reel change, the surface mounter M13 has a suction error, the surface mounter M21 on the production line L2 has a suction error, and the surface mounter M23 has a reel change. In this case, it is assumed that the work plan 60 shown in FIG. 12A is selected as the work plan in which all the generated works are finished early.

The target time in FIG. 12A is the target time when all the work is completed. A target time is set by the worker assignment device 1 . For example, the surface mounter M does not immediately stop when reel replacement occurs, but it will eventually stop if the reel is not replaced. The worker assignment device 1 sets the target time before the time when the surface mounter M stops due to the reel not being replaced. Alternatively, when an adsorption error occurs, the surface mounter M immediately stops. In this case, if a target time until recovery is set, the worker assignment device 1 sets that time as the target time. The setting of the target time is not limited to these, and can be set as appropriate.

In the work plan 60 shown in FIG. 12A, the time for completing all the work is shorter than the target time. That is, there is surplus time before the target time. For this reason, as in the work plan 61 shown in FIG. 12B, the worker assignment device 1 assigns each worker a job with a low proficiency level for education within a range not exceeding the surplus time. Specifically, since the worker A on the production line L1 has a low proficiency in reel replacement, the worker assignment device 1 replaces the reel (Fig. 12B In the example shown in FIG. 2, the reel exchange of the surface mounter M11) is assigned. On the other hand, since the worker B on the production line L2 has a low proficiency in dealing with the pickup error, the worker assignment device 1 replaces one of the reels assigned to the worker B to deal with the pickup error (see FIG. 12B). In the example shown, the countermeasure for the pickup error of the surface mounter M21) is assigned.

In the example shown in FIG. 12B, the time to complete all the work is shorter than the target time even in the work plan 61 after changing the worker assignment. The worker assignment device 1 repeats assignment changes until the target time is exceeded, and transmits the work plan immediately before the target time is exceeded. The work plan to be transmitted does not necessarily have to be the work plan immediately before the target time is exceeded. For example, each worker may change only one work.

(Creation example 7)
Creation example 7 is an example in which "all lines" are selected as the production line setting, "proficiency level priority" is selected as the proficiency level setting, and "work subdivision" is selected as the work subdivision setting.

FIG. 13A is an example of the work that has occurred. In the example shown in FIG. 13A, reel replacement occurs in the surface mounter M11 on the production line L1, and work does not occur on the production line L2.
As shown in FIG. 13A, the reel replacement can be subdivided into the work of preparing a new reel, the work of removing the reel currently in use from the surface mounter M11, and the work of mounting the new reel on the surface mounter M11. Of these operations, the operation of preparing a new reel and the operation of removing the reel currently in use from the surface mounter M can be performed by different operators in parallel. Therefore, when "subdivide work" is selected, the worker assignment device 1 subdivides the work if there is a margin in the number of workers, and assigns workers to each subdivided work. For a plurality of subdivided tasks, it is possible to appropriately determine which worker is assigned to which task.

A work plan 62 shown in FIG. 13B is an example of a work plan in which work is subdivided. In the example shown in FIG. 13B, the work of preparing a new reel is assigned to the worker A of the production line L1, and the work of removing the reel currently in use from the surface mounter M and the work of preparing a new reel are assigned to the worker B of the production line L2. A task of mounting the reel on the surface mounter M is assigned. By assigning a worker to each subdivided work, the time required to complete the work can be shortened.

(5-1-3) Flow of Creation and Transmission of Work Plan A flow of creation and transmission of a work plan will be described with reference to FIG. This process is started when one or more operations occur in the board production equipment 2 . Here, an example will be described in which "specified line priority (with interruption)" or "designated line priority (without interruption)" is selected as the setting of the production line.

In S101, the worker assignment device 1 receives position information representing the position of the mobile terminal 30 (in other words, the position of the worker carrying the mobile terminal 30) from the mobile terminal 30 of each worker.
In S102, the worker assignment device 1 selects work from the viewpoint of shortening the travel time based on the position of each worker represented by the position information received in S101 and the proficiency level of each worker for each work. Create a plan and a work plan from the viewpoint of shortening the work time (an example of the creation process and creation process).

In S103, the worker assignment device 1 transmits to the mobile terminal 30 of the worker (an example of a predetermined transmission destination) the work plan that completes all the work that occurred the earliest among the work plans created in S102 (transmitting step and an example of transmission processing).
In S104, the worker assignment apparatus 1 determines whether or not all the work of the work plan transmitted in S103 has been completed.

In S105, the worker assignment device 1 determines whether or not new work is occurring on the designated line. The worker assignment device 1 returns to S104 if no new work has occurred, and returns to S101 if new work has occurred, and repeats the process. When the process returns to S101, a work plan in which the new work is interrupted by the work of the worker on the non-designated line is recreated and sent to the worker.

(5-2) Training Necessity Notification Processing For each worker, the worker assignment device 1 looks up the work time table to tally the number of times of work for each work and calculates the average work time for each work. The worker assignment device 1 refers to the standard/allowable work time table and determines whether or not the average work time is longer than the standard work time for the number of times of work. The worker assignment device 1 notifies the administrator terminal 31 (predetermined notification destination (an example) (an example of the first notification step). The worker assignment device 1 may send an e-mail to the manager's e-mail address indicating that worker education is required.

(5-3) Work Delay Notification Processing With reference to the standard/allowable work time table shown in Table 2, work delay notification processing will be described. When the work time exceeds the allowable work time, even if the board production equipment 2 does not stop immediately, the board production equipment 2 may stop as it is. When the mobile terminal 30 notifies the worker assignment device 1 of the start of work, it starts counting the work time. The terminal 31 is notified (an example of the second notification step). The worker assignment device 1 may send an e-mail to the e-mail address of the manager that the allowable work time has been exceeded.

(5-4) Proficiency level update process The worker assignment device 1 refers to the work time table, aggregates the cumulative work time of each work for each worker, and updates the proficiency level table according to the cumulative work time. update proficiency in For example, the worker assignment device 1 assigns a proficiency level of 0 when the cumulative work time is 0 to 10 hours, a proficiency level of 1 when the cumulative work time is 10 to 20 hours, and a proficiency level of 2 when the cumulative work time is 20 to 30 hours. (an example of an update process).

Although the case where the proficiency level is updated based on the cumulative work time has been described as an example, the proficiency level may be updated based on the cumulative number of times of work. For example, the proficiency level may be updated to 0 when the cumulative number of operations is 0 to 10, to 1 when the cumulative number of operations is 10 to 20, and to 2 when the cumulative number of operations is 20 to 30.

(6) Effect of Embodiment According to the worker assignment method according to the first embodiment, based on the position of each worker and the proficiency level of each worker with respect to the work that has occurred, the worker assigned to each work and each work Create a work plan that represents the work order and For this reason, according to the worker assignment method according to the first embodiment, compared to the case where the worker (or manager) decides to deal with the situation, the workers are arranged so that all the work occurring in the board production equipment 2 can be completed in a short time. can be assigned.

According to the worker assignment method described above, a plurality of work plans with different workers assigned to the work are created, and the work plan that completes all the work that occurred the earliest among the created work plans is specified as a predetermined work plan. Since it will be sent to the destination, it is more likely that all the work that has occurred will be completed in a short time.

According to the above worker assignment method, a work plan from the viewpoint of shortening the travel time and a work plan from the viewpoint of shortening the work time are created, and among the created work plans, the work plan that completes all the work fastest is selected. Send. Therefore, compared to creating a work plan that considers only travel time or only work time, it is more likely that all the work that has occurred will be completed in a short time. .

According to the worker assignment method described above, since it includes a reception process for accepting settings as to whether to assign each worker only the work of the production line L in charge, or to assign work other than the production line L in charge to each worker, The degree of freedom in assigning work is improved compared to the case where only the work that occurred on the production line L is assigned or the work other than the production line L in charge is also assigned.

According to the worker assignment method described above, when new work occurs on a designated line, the new work is assigned to a worker who is working on a non-designated line. can be terminated with

According to the above worker allocation method, in the case of "designated line priority (with interruption)", the current work of the worker who is doing the work that occurred on the non-designated line is interrupted and new work is interrupted. The work that occurred on the designated line can be completed in a short time.

According to the above worker allocation method, in the case of "designated line priority (no interruption)", after the current work of the worker who is doing the work that occurred on the non-designated line, before the next work of the worker can be interrupted by the new work, the work that occurred on the designated line can be completed in a short time.

According to the worker assignment method described above, when "priority on education" is set, workers with relatively low proficiency in each task are preferentially assigned to each task. Therefore, it is possible to improve the proficiency of the operator.

According to the worker allocation method described above, when "surplus time training" is set, workers can be trained to the extent that all work is completed within the target time. can educate people.

According to the worker assignment method described above, when the number of workers is larger than the number of works, one work is subdivided and a plurality of workers are assigned, so that the time for completing the work can be shortened.

According to the worker assignment method described above, when the work time of a worker is longer than the standard work time of the work, the manager terminal 31 is notified that the worker needs training for the work. This notification makes it easy for the manager to determine which worker needs training for which task.

According to the worker assignment method described above, when the actual work time exceeds the allowable time, the manager terminal 31 is notified that the allowable time has been exceeded. By instructing other workers to help, work delays can be suppressed.

According to the worker assignment method described above, for each worker, the proficiency level of the worker is automatically updated based on at least one of the cumulative work time of the work and the number of cumulative work of the work. The burden on the administrator can be reduced compared to when the administrator who manages manually updates the proficiency level.
