Abstract

PURPOSE:To provide a work composing device which can easily cope with the monthly or irregular variance of the production or the personal when the work is composed (or the persons are arranged) on a production line. CONSTITUTION:All jobs included in a composing range are divided into the jobs which are restricted by a work network and the working order cannot be changed and the free jobs which are not restricted by the work network. The data on these divided jobs are stored in a data file 2. Meanwhile a composition pattern consisting a 1st type person section where all restricted jobs and some free jobs are assigned and a 2nd type person section where only the free jobs are assigned. Then a composition rule is produced to first assign the part of restricted jobs and then the part of free jobs of the composition pattern. This rule is stored in a composition rule memory 3. A composition processing part 1 assigns the jobs to each person based on the composition rule.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work knitting apparatus which can easily cope with production changes and personnel changes in work knitting on a production line.

[0002]

2. Description of the Related Art In a recent automobile factory, with respect to line work organization, work is automatically assigned to each worker in accordance with a predetermined organization rule. For production fluctuations (number of units produced, production ratio, production tact, etc.) and personnel fluctuations (increased or decreased personnel due to relocation of workers, etc.), the supervisor generally corrects the inconvenient parts each time. The monthly organization is changed by repetition.

As a knitting method at that time, for example,
The production tact (hereinafter simply referred to as “tact”) and the allocation rule are set in advance, and then the setting is simply done without considering the attribute of the work to be allocated (whether the work order is fixed or not). According to the allocation rule, the work is allocated so that the takt time is not exceeded.

[0004]

However, in such a conventional knitting system, when the tact or the number of personnel changes, the knitting cannot be largely changed in consideration of the skill level of the operator. Many. In addition, it is difficult for the supervisor to correct trial and error because the original formation itself was not built on the assumption of such fluctuations. For this reason, there is a demand for a flexible formation that can easily cope with production fluctuations and personnel fluctuations.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a work knitting apparatus which can easily cope with production fluctuations and personnel fluctuations.

[0006]

In order to achieve the above object, in the work organization apparatus of the present invention, a work element indicating at least one work is a first type work that constitutes a work network whose work order cannot be changed. A storage unit for separately storing the element and a second-type work element independent of the work network, a first-type personnel section to which at least the first-type work element is assigned, and a second-type work element only A second type of personnel section that is set, and the first type of work element stored in the storage means is set in each of the first type of personnel groups so as not to exceed a preset tact according to a predetermined allocation rule. After the allocation, the first-type work elements stored in the storage unit are kept from exceeding the preset tact according to a predetermined allocation rule. Those having a knitting means for allocating to each ward and the second type man Ward.

Further, in another work knitting apparatus of the present invention, a storage means for storing data regarding a work amount that can be moved and a fixed work amount that is not moved for each worker, and an existing knitting result and the data are stored. Based on this, there is knitting means for changing the work allocation so as not to exceed the preset tact according to a predetermined allocation rule.

The tact is preferably set for each worker.

[0009]

In the work organization device thus configured, each work element is divided into a first type work element and a second type work element, depending on whether or not the work element is bound to the work network. The knitting pattern is at least the first
It is made up of a first-class work area to which seed work elements are allocated (that is, a second-class work element may be allocated) and a second-class work area to which only second-class work elements are allocated. The knitting means stores the first type work elements stored in the storage means into the respective first type personnel districts so as not to exceed a preset tact according to a predetermined allocation rule, and then stores the first type work elements in the storage means. The second-type work elements that are present are allocated to each of the first-type and second-type individual wards so as not to exceed a preset tact according to a predetermined allocation rule.

Further, in the other work knitting apparatus, data relating to the work amount that can be moved and the fixed work amount that is not moved is set for each worker, and new production data is input to the knitting means. Then, based on the existing knitting result and the data, the work allocation is changed so as not to exceed the preset tact according to a predetermined allocation rule.

In this case, considering the skill level of the operator,
It is preferable to set the tact for each worker in terms of efficiency.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an example of a work organization device according to the present invention. The knitting processing unit 1 is composed of a CPU or the like, and executes arithmetic processing relating to work knitting (or staffing). A data file 2, a composition rule memory 3, a composition result memory 4, and an input / output interface 5 are connected to the composition processing unit 1. A keyboard 6, a display 7, and a printer 8 are connected to the interface 5. A result editing unit 9 is connected between the input / output interface 5 and the knitting result memory 4. The storage means is composed of the data file 2,
The knitting means is composed of a knitting processing unit 1 and a knitting rule memory 3.

The data file 2 stores various data necessary for line work organization. Specifically, roughly classified, work data regarding work, worker data regarding workers, production data regarding production, and facility data regarding facilities are stored. The work data represents each data for at least one work (for example, main harness mounting work) as a work element,
It consists of reference time (time required for one work), work priority, tools used, work parts, applicable equipment, and the like.
Further, in the present embodiment, as work data, a work network in which the work order cannot be changed is constrained (hereinafter referred to as constrained work), or a work which is independent of the work network in a certain knitting range and is not constrained thereto (hereinafter referred to as constrained work). , Free work). Specific examples of the restraint work and the free work are as shown in FIG. Here, as the work networks, three work networks of a cabin-related work, a door-related work, and a window-related work are shown. The first type work element is configured by a restraining work, and the second type work element is configured by a free work. Next, the worker data consists of the proficiency level of each worker for a certain work, and the production data is the planned production quantity,
It is formed from the production ratio and the production tact.
Equipment data are line specifications.

The knitting rule memory 3 stores knitting rules serving as a reference for allocating the work to each worker's section, and the contents of the knitting rules are as described below.

When considering a formation that is easy to cope with monthly production fluctuations and personnel fluctuations, the elements that change in the composition are tact and personnel (all other elements are linked to tact and can be omitted). ), It can be said that the required formation is one that can respond to changes in tact and personnel. Therefore, in this embodiment, as shown in FIG. 2 (A), each worker is assigned a restraining work (N) and a little free work (F), and one worker is assigned to some workers (one worker to four workers in the figure). In other words, a mixed type knitting pattern is formed in which a worker who is in charge of only free work (F) is provided at a ratio of). The 1st division is a division to which restraint work (N) and free work (F) are assigned (however, it is possible to assign no free work (F) at all), and the 2nd division is free work. Only (F) is a division that is assigned. By adopting such a knitting pattern, it becomes possible to easily deal with the increase or decrease of the tact or the number of personnel. For example, increase in tact (T
For 1 <T2), as shown in FIG. 2 (B), the work of the worker (second type personnel ward) who was in charge of only free work (F) is performed by other workers (first type). It can be distributed in the free time due to the increase in tact time in the (person's ward), and conversely, decrease in tact time (T3> T
For 4), as shown in FIG. 2 (C), the free work (F) for the tact reduction is collected and a new worker (the second kind person section) who is solely in charge of the free work (F) is newly collected. It should be provided.

The knitting rules for forming such a knitting pattern will be described in detail later, but basically, the restraint work stored in the data file 2 is set in advance according to a predetermined allocation rule. T ') is allocated to each first-class individual ward so that the free work stored in the data file 2 does not exceed a preset main tact (T) according to a predetermined allocation rule. Allocate to each of the 1st and 2nd divisions. Here, the sub-tact (T ') is obtained by the following formula: sub-tact (T') = main tact (T) x restraint work rate, sub-tact (T ') <main tact (T)
Has been established. The restraint work rate is a set ratio of restraint work (N) and free work (F).

Further, the same standard as the conventional one is used as the allocation rule constituting the knitting rule. That is,
As for the condition of work selection, the absolute condition that should be absolutely protected,
There are requirements that are required in terms of work efficiency and work load. Furthermore, absolute conditions are to keep work priority,
There are two things to keep fixed equipment conditions (line specifications),
In addition, the necessary conditions are to concentrate the use of the same tool (hereinafter referred to as "the same tool"; hereinafter the same), avoid work interference ("work interference"), and concentrate heavy muscles and minute work. Should be avoided ("heavy muscle / fine"), two people should perform symmetrical work ("symmetrical work"), work for the same part should be assigned to the same worker ("same part"), Concentrate work on the same part (“same part”), secure parts storage (“parts storage”), and avoid mixing work for parts that are less likely to get dirty and work for parts that are easily soiled by workers. There are things to do (“clean / dirty”). The work allocation is calculated in accordance with such a work selection condition, and the conditions can be prioritized in advance and the knitting is organized according to this priority. For example, regarding the priority order of the necessary conditions, avoidance of work interference is a knitting condition between lines, and the knitting condition within one stage of a line is the same part, the same tool, the heavy muscle / fine priority order. The pattern 1 to have and the pattern 2 having the same tool, the same part, and the priority order of heavy muscle / fine can be arbitrarily set, and what kind of priority is given (that is, which pattern is used for knitting) Can be freely set or selected by operating the operator's keyboard 6 according to the situation.

The keyboard 6 performs input processing of various data and commands, the display 7 displays the knitting result and the like on the screen, and the printer 8 outputs various forms. Further, the output to the display 7 and the printer 8 is created in a predetermined format in the result editing section 9.

The knitting processing unit 1 executes work knitting (or staffing) in a certain range in accordance with the knitting rules stored in the knitting rule memory 3 while looking up various data in the data file 2. Is as shown in FIG. 3, for example.

First, when the operator operates the keyboard 6 to input parameters such as tact and priority (S
1) The knitting processing unit 1 fetches necessary data while looking up the data in the data file 2 (S
2) The knitting process is executed according to the knitting rule stored in the knitting rule memory 3.

That is, first, based on various data,
In addition to existing processes (eg total work time, total work time by region, total time of subsequent work for each work, etc.), pre-processing calculation such as classification of restricted work restricted by work network conditions and free work not restricted by it Is executed (S
3). Then, preconditions (for example, tact time over work, work order (network) relationship is consistent, work order / work attribute between same work is consistent (at the time of mixed flow organization), the number of stages is sufficient, etc. ) Is checked (S4), and if it is NG, it ends immediately, but if it is OK, the first stage (first-class race) is set (S5), and assignment of restraint work is performed (S6). .
At this time, the work is narrowed down and selected in accordance with the above-mentioned allocation rule so as not to exceed the sub-tact determined by the main tact × constraint work rate. For example, according to the above-mentioned pattern 1, that is, the same part, the same tool, the priority order of heavy muscle / fine, and the constraint condition according to the allocation state at this time, the work is narrowed down to one work and assigned. This is the end condition of the human ward (stage) (for example, the total time of allocation work is within ± 5% of the production tact (weighted average of each model), and the allocation time for each model is ± 20 of the production tact. %) Is satisfied (S7), and if there is remaining restraint work (S8), the next stage (first-class division) is set (S9) and the process returns to step 6. . If there is no remaining restraint work in step 10, it is judged that the assignment of restraint work has been completed, and the result of the assignment of restraint work is continued. Additional allocation is performed (S10). The takt at this time is the main takt, and the allocation rule may be the same pattern as in step 6 or another pattern different from step 6.

When the knitting is completed, the knitting result is sent to the knitting result memory 4, edited by the result editing section 9 into an appropriate format, and then output from the display 7 or the printer 8 (S11).

FIG. 5 shows a specific example in which the work group shown in FIG. 4 is knitted using this embodiment. In the same figure (A), a certain organization result in the main tact T5 is shown, and the workers in each section are represented by A, B, C, D and E. In the figure, the white parts represent restraint work, and the netted parts represent free work. In addition, the workers A, B, C,
D is a worker of the first kind people's ward, and worker C is a worker of the second kind people's ward. Based on this, FIG. 5 (B)
Shows the case where the tact increased, and FIG. 5 (C) shows the case where the tact decreased. As shown in FIG. 5 (B),
When the main takt time increases from T5 to T6, the free work of the worker C who is in charge of the second race is simply performed by the workers A, B, C, and D who are in charge of the first race. By distributing, it is possible to cope with the increase in tact. Further, in this case, the worker C is unnecessary, and the number of personnel is reduced. On the other hand, as shown in FIG. 5C, when the main tact decreases from T5 to T7, the free work of the parts of the workers A to E exceeding the main tact T7 is collected and newly added. The work is allocated to the worker F, and the remaining free work is allocated to the other unsatisfied worker X. In this case,
We respond to the decrease in tact by adding a second-class ward, that is, by increasing the number of personnel.

Therefore, in the present embodiment, all the work within the knitting range is divided into a restricted work that is restricted by the work network whose work order cannot be changed and a free work that is not restricted by the restricted work, and a small amount of the restricted work. A knitting pattern is composed of the first type of personnel division to which free work is assigned and the second type of personnel division to which only free work is assigned, and the restraint work part of this knitting pattern is assigned first and then the free work of that knitting pattern Since the parts are allocated, it becomes possible to easily cope with production fluctuations and personnel fluctuations centering on tact changes in the work organization (or staffing) of the production line.

Next, another embodiment of the present invention will be described. The work knitting apparatus in this embodiment is an apparatus in which the existing knitting result is effectively used to easily cope with, for example, monthly production variations, and its schematic configuration is the same as that shown in FIG. . However, in the present embodiment, the data group stored in the data file 2 includes the monthly organization conditions (deletion / additional personnel area, new work rate, new work count, fixed rate, rating), which will be described in detail later. Personnel data, production data, work data / same work data, equipment data, and existing organization (allocation stage, allocation section). Also in this case, the storage means is composed of the data file 2, and the knitting means is composed of the knitting processing unit 1 and the knitting rule memory 3.

The formation rule is stored in the formation rule memory 3, but in the present embodiment, new production data (product mix = vehicle type / vehicle type in the production amount) based on the past (for example, the previous month) formation result. According to the composition ratio, etc.), the reorganization is performed according to the following conditions. That is, as shown in FIG. 6, a work amount P that can be moved and a fixed work amount Q that does not move are set for each worker (for example, A, B, C, D) that constitutes a division. The movable work amount P and the fixed work amount Q are set by setting a new work rate, a new work number, and a fixed rate. Here, the new work rate is the ratio of the possible new allocation work to the takt time, the new work number is the maximum number of the new allocation work that is possible, and the fixed ratio is the ratio of the work that you want to keep as it is to the takt time. Is. If the new work rate is a%, the fixed work rate is represented by (100-a)%. Further, the rating is input to each worker, and the tact for each worker can be set according to the value. These data (new work rate of each worker, new work number, fixed rate, rating (tact)) are stored in the data file 2 as the monthly organization condition as described above. As described above, since the new work rate and the fixed rate have a relationship in which one can be derived from the other, only one of the values may be input.

Further, in the present embodiment, the knitting process is performed in the form of movement of the work in the human section in order to perform the re-knitting by utilizing the existing knitting result. Therefore, the allocation rules that make up the organization rules appear as conditions for work movement. There are absolute conditions (such as work side, clean / dirty, etc.) that must be strictly adhered to as conditions for this work movement, and work can be moved in accordance with a predetermined movement work priority while complying with these absolute conditions. ing. Here, the "working side" as an absolute condition is determined in relation to the component supply. For example, if a part storage area is on the right side of the line, it is not efficient to take a detour and take the part to the left side of the line. Also, "clean / dirty" is
As described above, it is necessary to avoid the mixture of the work of the component object that is disliked to be contaminated and the work of the component object that the worker easily stains.

The priority of the mobile work is set so that the restriction of the work network can be avoided as much as possible in consideration of the distinction between the restricted work and the free work related to the work network described in the first embodiment. Specifically, free work is prioritized for movement.

For example, in the case of moving the work to the unsatisfied section, the work is moved from the rear section, and the priority of the moving work at that time is "free work &"Same part work", "Free work & same block work", "Free work", "Direction or room block" work, "There is subsequent work" work, "Same block as allocation block" work, "Assignment site" These are the "same part" work, "there are many subsequent works that change the earliest" work, and "closest to the current person". In the actual processing, these priorities are used in the form of a logical product (AND condition) from above.

Here, in the above-mentioned "directional or room block" work, the directional work means that the work site is the right side of the front part of the body side (BFR) and the right side of the center of the body side (BCR). , The rear right side of the body side (BRR), or the front left side of the body side (BRR)
FL), the left side of the center of the body side (BCL), and the left side of the rear part of the body side (BRL). Room block work means that the work part is in the engine room (E
R), around the dash panel (DA), in the center of the cabin (CRC), around the center pillar on the left side inside the cabin (CRL), around the center pillar on the right side inside the cabin (CRR), inside the trunk room (TR) Say.
In the existing knitting result, the position of the worker (right side or left side) and whether or not the room block work is performed are determined. Therefore, it is advantageous to digest the above-mentioned work, which is the basis of these operations, in a section before the knitting. This is because there is a risk that allocation will not be possible if there are people left behind. For example, the work on the left side of the direction is NG on the right side. In addition, as for the work “with a subsequent work”, if the work having the work connected to the rear on the network is brought, the movable range of the subsequent work is expanded. Also, regarding the “same block as the allocation block” work, it is better to bring the work of the same block as the existing knitting result, because the block knitting can be protected. Also, regarding the “same part as the allocated part” work, the condition of the same part is protected if the work of the same part as the existing knitting result is brought. Further, it is because it is advantageous that the number of work is large as to the work “there are many subsequent works changing the earliest” for the same reason as in the case of the work “there are subsequent works”. The reason for the work "closest to the current division" is the same as the case of the work "there is a follow-up work" or the work "there are many follow-on works whose earliest changes". In other words, if the work is brought from a section close to the current section, there is more opportunity for a chained movement in which the work that follows it moves and the work that changes the earliest time appears again.

In addition, when moving a work from a tact-sufficient section, the work is moved to a rear section, and the priority of the moving work at that time is, in order from the highest,
“Free work & minimum block & minimum part”, “work without directionality other than room”, “minimum block & minimum part”. These priorities are also used in the actual processing in the form of a logical product (AND condition) from above.
Here, “work without directionality other than the room” means work in which the work portion is around the front end (FR) and around the rear panel (RR). Since these works are compatible with the section to which any work is assigned, even if these pieces of work are brought in, there is a high probability that they can be incorporated into the organization in that section. Regarding the "minimum block & minimum part", if these operations are eliminated from the existing knitting result, the block knitting and the condition of the same part can be further protected.

As conditions for the moving work, there are further set conditions that "the time value = 0 cannot be moved by free work" and "the work having a succeeding time value = 0 can be moved". Here, the time value indicates the time required for the work.For example, when the number of units in the month is small in optional work such as attaching a wiper to the headlight in a Nordic vehicle, the time value is the weighted average value. The value may be 0 (for example, rounded to two decimal places). In this case, when the work is free work, it does not affect others, so it is better not to move it (the former condition). On the other hand, even if the time value is 0, if there is a subsequent work, it may be possible to move other work by moving it, so it is better to use it as the target of movement (in the latter case). conditions).

The knitting processing unit 1 changes the work knitting in a certain range according to the knitting rules stored in the knitting rule memory 3 with reference to various data in the data file 2, and its flowchart is shown in FIG. 7, for example. It is as follows.

First, by operating the keyboard 6 by the operator, the monthly organization conditions (deleted / added personnel area, new work rate, new work number, fixed rate, rating), production data, and
Various data such as work data / same work data, equipment data, and existing organization (allocation stage, assigner section) are input and stored in the data file 2 (S20). If the data of the existing composition is stored directly in the data file 2 from the composition result memory 4, it is not necessary to manually input the data every time the composition is changed monthly.

When the necessary data input is completed, the knitting processing unit 1 sets the movable range (earliest stage and latest stage) for each work according to the existing knitting data (S2).
1), deletion / addition is performed based on the data of deletion / additional division (S22). When adding a division, a division is created on the specified stage, and when deleting a division, the work of the division to be deleted is moved to the stage as soon as possible while observing the absolute conditions. Then, select the ward to be considered (S2
3), it is determined whether or not the work allocation has been completed for all the districts (S24). The reorganization is complete when all the districts are completed.

On the other hand, if the work allocation has not been completed for all the people's blocks, the allocation time up to now (for example, the weighted average of all vehicle types) and the input for the people's blocks selected in step 23 are input in step 1. The tact for each worker is compared (S25). In addition, in the case of basic organization,
Although the weighted average time of the vehicle system is used as the value for determining the end, here, the weighted average is performed using the concept of a vehicle type finer than the vehicle system. For example, if the vehicle system P includes vehicle types a, b, and c, and the vehicle system Q includes vehicle types d, e, f, and g, the weighted average of vehicle types a, b, and c = time of vehicle system P Value Weighted average of vehicle types d, e, f, g = time value of vehicle system Q, and weighted average of vehicle systems P, Q = weighted average of all vehicle types a to g is established. Therefore, in step 25, the weighted average of all vehicle types may be replaced with the weighted average of all vehicle types.

As a result of the determination in step 25, when the allocation time is not satisfied, that is, when the weighted average of all vehicle types does not satisfy the tact of the worker, it is determined whether or not there is a movable work on another stage. Yes (S26). This judgment is made according to the set earliest / latest stage. Specifically, in the case of this unsatisfied person section, when the earliest stage value of the work of the succeeding person section is less than or equal to the current (unsatisfied) person section, it is determined that there is work that can be moved.

If there is a work that can be moved to another stage as a result of the judgment in step 26, the work is moved to the unsatisfied section from the rear section and the tact is satisfied (S2).
7). As described above, the priority of the moving work at this time is “free work & same part work”, “free work & same block work”, “free work”, “with directionality” "Room block" work, "There is a subsequent work" work, "Same block as allocation block" work, "Same part as allocation site" work, "Many subsequent works that change the earliest" work, "Closest to current population" Work is set.

As a result of the determination in step 25, when the allocation time is over, that is, when the weighted average of all vehicle types exceeds the tact of the worker, it is determined that there is a movable work on this stage. As a condition (S2
8) Then, the work is moved from this over-sufficient area to the rear area and the tact is satisfied (S29). The judgment in step 28 is made according to the set earliest / latest stage, similarly to the judgment in step 26. Specifically, in the case of this overfilled section, when the latest stage of work in the current (overfilled) section is equal to or greater than the current stage value, it is determined that there is work that can be moved. As described above, the priority of the moving work in step 29 is, as described above, the AND condition.
"Free work & minimum block & minimum part", "work without directionality other than room", "minimum block & minimum part" are set.

When the work is moved in step 27 or step 29, the earliest / latest stages of the work connected to the work by the network change (see, for example, FIG. 8), so that the earliest and latest stages are changed. After making the change (S30), the process returns to step 25.

Further, when the allocation time is satisfied as a result of the determination in step 25, when there is no work that can be moved to another stage as a result of the determination in step 26, or the stage concerned is determined as a result of the determination in step 28. When there is no work that can be moved to, the process returns to step 23 and the subsequent processing is repeated. Then, when it is determined in step 24 that the division has ended, a series of knitting processing ends.

Therefore, in this embodiment, a new work rate, a new work number, and a fixed rate are set for each worker, and these conditions are taken into consideration, and the existing knitting result is obtained based on the new production data. Since it is changed, it is possible to effectively use the existing knitting result and to easily cope with, for example, monthly production fluctuations.

Further, since the rating is input for each worker to set the tact for each worker, it is possible to further reflect the skill level of the worker in the work organization and further improve the efficiency. Is planned.

As described above, according to the present invention, each work element is divided into a first-class work element and a second-class work element, and a knitting pattern is formed in the first-class personnel section and the second-class personnel section. The production line is organized (or staffed).
Will be able to easily cope with monthly or irregular production fluctuations and personnel fluctuations.

Further, when setting the data regarding the movable work amount and the fixed work amount which is not moved for each worker, it is possible to change the work formation by effectively utilizing the existing formation result.

Further, when the tact is set for each worker, the efficiency can be further improved in consideration of the skill level of the worker.
