Abstract

PURPOSE:To perform automatic decision and indication of proper production allotment of a system in a short time to produce plural kinds of articles in a plurality of production lines. CONSTITUTION:In a production allotment indicating device M2, the number of productions per line is allotted by an allotting means M6 based on data, such as the number of production DS, an order W of kinds, an order K of lines, and the number DL of production possibility per line, which are stored in an allotment data memory means M4. When allotment is impossible, a re- allotment means M10 is stated and a line JA where the number of remaining production possibility is one line or more is specified by a line specifying means M12. A kind IB producible in a line JA is retrieved by means of a kind retrieving means M14. With regard to the kind IB, an already allotted line is retrieved by a line retrieving means M16 to specify a line JC. A content of the king IB allotted to the line JC is re-allotted to the line JA by the number DS (I) of production at a time when allotment is impossible, by means of a re-allotment practising means M18 and the number DS (I) of productions of a kind allotment of which is made impossible is allotted to the empty line JC.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a production allocation instructing device for determining and instructing allocation of each type of article to a production line in a system for producing a plurality of types of articles on a plurality of production lines. In addition, all products, parts, and the like produced by this production system are referred to as articles in this specification. Further, in this specification, the term "production" or "production processing" refers to any operation on the material, such as not only processing operations such as cutting but also operations related to production such as assembly of parts. Is widely included.

[0002]

2. Description of the Related Art With the trend of diversification of products and the like, a production system for producing a plurality of types of articles on a plurality of production lines has been widely used. In order to improve the production efficiency in such a production system, the allocation of which article and how many articles are produced in each production line is the most important factor. In particular, it is required to equalize the operating rate among a plurality of production lines. In the past, such production allocation decisions were often made manually by experienced managers or the like with a wealth of experience. That is, the skilled manager or the like has decided the allocation by judging, based on past experience, how many articles of which kind should be produced in each production line. According to the production allocation determined in this way, a plurality of types of articles are produced in the production system.

[0003]

However, as the number of types of articles produced in each production line increases as the number of products increases, the number of combinations of production allocations in the production system as described above can be considered innumerably. Became. As a result, it takes a very long time to manually determine the production allocation even by an experienced person. Further, in the conventional method, only a skilled person can determine the production allocation, which causes a problem of extremely low efficiency in production management. For this reason, there has been a demand for an assignment instructing device that enables even an unskilled person to determine an accurate production assignment in a short time. Therefore, the present invention provides a production allocation instructing device capable of automatically determining and instructing accurate production allocation in a system for producing a plurality of types of articles on a plurality of production lines in a short time. With the goal.

[0004]

Therefore, in the present invention, in order to solve the above-mentioned problems, a production allocation instructing device M2 whose construction is schematically shown in FIG. 1 was created. That is, the production allocation instructing device M2, for each type i (i = 1 to NS) of the article to be produced, the production number DS (i), the type order W (i), the line order K (i, j) (j = 1 to NL) and the producible number DL (j) for each line, the allocation data storage means M4, the type order W (i) as the main order, and the line order K (i, j) as the sub order. Then, the allocating means M6 for allocating the production quantity by line for each type, the reallocating means M10 which is started when the allocating means M6 becomes in the unallocatable state, and the allocating means after the operation of the reallocating means M10 is completed. In the production allocation instructing device M2 including the allocation resuming means M8 for restarting M6, the reallocating means M10 includes a line specifying means M12 for specifying a line JA having a remaining producible number of 1 or more, and a type order W ( Assign i) as the main order Types retrieval means M14 continue to search for producible types IB in specified line JA in line specification means M12 than category list when capacity in the direction to decrease by one,
Line search means M1 that searches for assigned lines in the direction in which the line rank of the line JA specified by the line specifying means M12 is decreased by 1 in the searched type IB.
6 and the line JC of the type IB specified by the type search means M14 to the line JC specified by the line search means M16, the line specified by the line specification means M16 by the production number DS (I) when it cannot be allocated. And a reassignment executing means M18 for reassigning to JA.

[0005]

Next, the operation of the production allocation instructing device of the present invention will be described.
This will be described with reference to FIG. As shown in FIG. 1, the production allocation instructing device M2 has an allocation data storage means M4.
An allocation means M6, a reallocation means M10, and an allocation restart means M8. Allocation data storage means M
4 shows, according to the type i (i = 1 to NS) of the article to be produced,
Number of products to be produced DS (i), type (1 to N
S) priority order W (i) indicating the priority order, and line order K (i, j) indicating the priority order between lines producing each type
(J = 1 to NL) and the number of producible lines DL by line
(J) is stored. Now, based on these allocation data, in the allocation means M6, the sort order W (i)
Is the main order, and the line order K (i, j) is the sub order, and the production quantity for each line is assigned for each type. That is, first, for the type having the first type order W (i), the line order K
(I, j) is assigned in order from the first line.

Here, when the allocating means M6 is in an unallocatable state, the reallocating means M10 is activated. The reallocation means M10 is composed of a line identification means M12, a type search means M14, a line search means M16, and a reallocation execution means M18. Now, when the allocating means M6 becomes in the unallocatable state, first, the line specifying means M12 specifies the line JA whose remaining producible number is 1 or more. Then, by the type searching means M14, the type IB which can be produced by the line JA specified by the line specifying means M12 in the direction in which the type order W (i) is set as the main order and is decreased by 1 from the type order when allocation is not possible. The search is done. Next, the line search means M16 searches for the assigned line in the direction in which the line rank of the line specified by the line specification means M12 in the searched type IB is decreased by one.

Then, the reallocation executing means M18 allocates the production quantity DS (I) of the type specified by the type searching means M14 to the line JC specified by the line searching means M16. ) Is reassigned to the line JA specified by the line specifying means M12. The line JC thus emptied is assigned the type of article that was previously unable to be assigned. After the completion of the operation of the reallocation means M10 as described above, the allocation restarting means M8 restarts the allocation means M6 to return to the normal allocation process. By the above operation, when a type becomes unallocatable during the normal allocation by the allocation means M6, the already allocated type is moved to the vacant line JA to Allocation is possible. By carrying out such reallocation, all types of articles to be produced 1
~ NS are reliably assigned to each line 1-NL. In this manner, the production allocation instructing device can automatically determine and instruct accurate production allocation in a system for producing a plurality of types of articles on a plurality of production lines in a short time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment embodying the present invention will be described with reference to FIGS. First, the basic configuration of the production allocation instructing device of the present invention and the allocation procedure will be described with reference to FIGS. FIG. 2 is a diagram showing the overall configuration of an embodiment of the production allocation instructing device according to the present invention. 3 to 5 are flow charts showing the procedure of allocation by the production allocation instructing device of this embodiment. As shown in FIG. 2, the production allocation instructing device of this embodiment uses a plurality of article types 1, ..., I, ...
In a system for producing on a plurality of production lines 1, ..., J, ..., NL, it is a device for determining the allocation of the articles 1 to NS to the production lines 1 to NL.

Here, as the allocation data 4, the number of production DS for each type i (i = 1 to NS) of the article to be produced.
(I), type order W (i), line order K (i, j) (j =
1 to NL) and the producible number DL (j) for each line are stored. That is, the allocation data 4 is W in order of type.
The data is in the form of a list in which (i) is arranged in the vertical direction and the line order is arranged in the horizontal direction. Here, <W> is
It is a variable that means a type whose type order is W. For example,
If the type order W (i = 1) of type 1 is 3, <3
> Means a type i of W = 3, that is, a type 1. On the other hand, it is also possible to use data in the form of a list in which the line numbers j are arranged in the horizontal direction like the allocation data 6. In this case, for example, for type 1, line 4
Assuming that (j = 4) is the first-ranked line, K (1,
4) = 1. At this time, in the allocation data 6, <K (1, j) = 1> means j = 4.

A specific control procedure will be described with reference to the flow charts of FIGS. The control program shown in the flowcharts of FIGS. 3 to 5 is stored in the ROM of the memory device of the production allocation instructing device, and the CPU (central processing unit) and RAM of the production allocation instructing device.
The above is repeatedly executed at short time intervals. Now, when the control is started in step S2, first, the number NS of types of articles to be produced is input. And this type i
The number of production DS to be produced from now on (i = 1 to NS)
(I), the type order W indicating the priority order among the types (1 to NS)
(I), the line order K (i, j) (j = 1 to NL) indicating the priority order between the lines producing each type, and the respective data of the producible number DL (j) for each line are input. (Step S4). According to these allocation data, the allocation process whose contents are shown in FIG. 4 is executed (step S6).

The specific contents of the allocation process in step S6 will be described with reference to the flowcharts of FIGS. When the allocation process starts in step S10, first, a variable I1 indicating the order of types to be considered
Is initialized. That is, 1 is input to the variable I1 (step S12). Then, the type order W (i) is I
The value of i that becomes 1 is specified, and this value of i is input as I (step S14). As a result, the type I to be assigned at the present time is specified. Next, a variable L1 indicating the line order to be considered is initialized. That is, 1 is input to the variable L1 (step S
16). Then, the value of j in which the line order K (i, j) matches the value of L1 (here, L1 = 1) is specified, and this value of j is input as J (step S18). As a result, the production line J currently under consideration for the type I is specified.

Then, it is judged whether or not the remaining producible number DL (J) of the specified line J is 0 or more (step S20). If the result of this determination is NO, the process moves to step S38 described later. On the other hand, the result of this judgment is Y
In the case of ES, that is, the remaining producible number of line J is 0
If not, it is determined whether or not the remaining production number of the type I in question, DS (I), is smaller than the remaining producible number DL (J) of the line J (step S22). If the determination result in step S22 is YES, that is, if DS (I) is smaller than DL (J), type I
It is decided to produce DS (I) pieces on the line J (step S24). As a result, the remaining production number DS (I) of type I becomes 0, and the remaining production number D of line J is D.
Since L (J) becomes DL (J) -DS (I), these values are input to the respective variables. On the other hand, step S
When the result of the determination in 22 is NO, that is, DS
If (I) is larger than DL (J), it is decided to produce DL (J) pieces of type I on the line J (step S26). As a result, the remaining production DS of type I
(I) becomes DS (I) -DL (J), and the remaining producible number DL (J) of the line J becomes 0, so these values are input to the respective variables.

After the processing in step S24, the value of the variable I1 is incremented by 1 in step S28 to obtain I
It becomes 1 + 1. Then, it is determined whether or not the value of the new variable I1 exceeds the number NS of types of articles to be produced (step S30). And the result of this judgment is YES
In this case, since the examination for all types has been completed, the control according to this flowchart ends (step S32). On the other hand, if the result of the determination in step S32 is NO, the process returns to step S14,
The above processing is continued. Further, after the processing in step S26, it is determined whether DS (I) is 0 (step S34). And the result of this judgment is YES
In this case, the process proceeds to step S28 described above. On the other hand, if the decision result in the step S34 is NO, the process advances to a step S36, and the value of the variable L1 is advanced by one.

Then, it is judged whether or not the new value of L1 exceeds the maximum value of the variable I, that is, the number of lines NL (step S38). And the result of this judgment is YE
In the case of S, it means that all the lines capable of producing the specific type i are full, that is, it corresponds to the unallocatable state. Therefore, the process proceeds to step S40, and the reassignment whose content is shown in FIG. The process is executed. The details of this reallocation process will be described later. On the other hand, step S
If the determination result in S38 is NO, step S
Returning to 18, the above-mentioned processing is continued.

Next, the specific contents of the reallocation process of step S40 will be described with reference to the flowchart of FIG. When the reallocation process starts in step S50, first, j in which DL (j) ≧ 1, that is, a line in which the remaining producible number is 1 or more is specified. Here, when there are a plurality of applicable lines, one of them is first identified and the line is set as the line JA (step S52). Next, the variable I2 for sequentially designating the type to be searched from the assigned types is initialized (step S54).
Then, the type corresponding to <W (I) -I2> is specified, and this type is set as IB (step S56). Here, IB = <W (I) -1>. by this,
As the already-assigned type to be searched, the type assigned immediately before the unassignable type is designated.

Next, it is judged whether or not the specified type IB can be produced on the line JA previously specified in step S52 (step S58). If the result of this determination is NO, the process moves to step S74 described below.
On the other hand, if the determination result in step S58 is YES, that is, if the type IB can be produced on the line JA,
A variable J2 for sequentially tracing back and specifying lines other than the line JA capable of producing the type IB to be searched is initialized (step S60). Then, the line <K specified by these variables IB, JA, J2
It is determined whether or not the type IB is assigned to (IB, JA) -J2> (step S62). When the result of this determination is YES, that is, <K (IB, JA)-
When the type IB is assigned to the line J2>, this line is set as the line JC. Then, in step S66, the reallocation process is executed. That is, the production number of the type IB on this line JC is DS (I).
The production number of the type IB in the line JA is reduced by DS
It is increased by (I). On the other hand, the remaining producible number of the line JC is increased by DS (I), and the remaining producible number of the line JA is reduced by DS (I) (step S6).
6).

After the reallocation process in step S66 is executed, a variable L1 indicating the line order to be searched is initialized (step S68). Then, the process is returned to step S18 of FIG. On the other hand, when the result of the determination in step S62 is NO, that is, <K (IB,
If the type IB has not been assigned to the line JA) -J2>, the process proceeds to step S70, and the value of the variable J2 is incremented by 1. Then, it is determined whether K (IB, JA) -J2 is 0 (step S72). If the result of this determination is NO, the process returns to step S62 and the above processing is repeated. On the other hand, if the decision result in the step S72 is YES, the process advances to a step S74, and the value of the variable I2 is incremented by 1. Then W
It is determined whether (I) -I2 is 0 (step S7).
6). If the result of this determination is YES, step S
Returning to 52, the above processing is repeated. On the other hand, if the determination result is NO, the process returns to step S56 and the above processing is repeated.

In this way, the processing of the flowchart of FIG. 5 is repeated until the reallocation processing of step S66 is executed, and if step S66 is executed, the variable L1
After initialization is performed, the process returns to step S18 in FIG. 4 and the normal allocation process is performed again. By this reassignment process, it is possible to assign the type i that cannot be assigned in the flowchart of FIG. As described above, when a specific type cannot be allocated in the middle of the normal allocation process shown in FIG. 4, the line is moved to a line where the type that has already been allocated is vacant. This enables the type of allocation. By carrying out such reallocation, all kinds of articles to be produced are surely assigned to each line.

Next, a specific example of control in a production line to which the production allocation instructing device 2 of this embodiment is applied will be described with reference to FIGS. 6 to 20. FIG. 6 is a diagram showing the overall configuration of a multi-product production system to which the production allocation instructing device 2 is applied. As shown in FIG. 6, the multi-product production system 10 to which the production allocation instructing device 2 is applied
The multi-product production system 10 includes a plurality of types of articles 1 to 1.
10 (enclosed by a circle in the figure) is a system for producing a plurality of production lines 12 to 20. This multi-product production system 10 includes a plurality of production lines 12-2.
0, storages 31 to 40 respectively storing a plurality of types of articles (1 to 10), and production lines 12 to 20
And a storage line 22 connecting the storages 31 to 40. That is, in this embodiment, there are 10 types of articles and 5 production lines.

Specific contents of control will be described with reference to FIGS.
This will be described with reference to 0. FIG. 7 is a specific example of data in which the production allocation instruction apparatus according to the present embodiment summarizes the order of types of articles to be produced, the number of productions on each production line, and the like. The data shown in FIG. 7 is obtained as a result of the input setting of each data in step S4 of FIG. 3 in the flowcharts of FIGS. 3 to 5 described above. In addition, in the present embodiment, as shown in FIG.
(I) and the type number i all match. Therefore,
8 to 20, only the type i is displayed in the vertical direction, and the type order W (i) is omitted. Also, each line 1
The number of products that can be produced in each of ~ 5 is 600, and the total number of products that can be produced in all lines, 3,000, is the same as the total number of products that can be produced in all types 1-10.

Now, with reference to the data shown in the table of FIG. 7, as a starting point, a concrete process when the allocation is executed according to the flow charts of FIGS.
-It demonstrates, referring FIG. 5 and FIG. 8-FIG. Figure 3
After the input setting process in step S4, the process proceeds to step S4, and the assignment process shown in FIG. 4 is executed. First, based on the procedure of steps S10 to S38 of FIG. 4, according to the type order W (i) (matches the type number i),
Allocation processing is executed for each type. As shown in FIG. 7, for the type 1 having the first rank W (i) in the order, all 500 production numbers can be assigned to the line 1 having the first rank in the line order. That is, the determination in step S22 of FIG. 4 is YES, and the total production number of type 1 500 pieces is assigned to line 1 in step S24 (FIG. 8). Similarly, for types 2, 3 and 4, the total number of productions is 470
, 420, and 350 are allocated to the line 3, line 5, and line 2 which are ranked first in the line order, respectively (FIGS. 9, 10, and 11).

Regarding the subsequent type 5, 500 pieces of type 1 have already been assigned to the line 1 which is ranked first in the line order, and the remaining producible number of the line 1 is 100 pieces, and the production number of the type 5 is 300 pieces. Less than. Therefore, it is determined to be NO in step S22 of FIG. 4, the process proceeds to step S26, and only the remaining producible number 100 of the line 1 out of the production number of type 5 is assigned to the line 1 (FIG. 12).
Then, the line 3 in the next line order (second place) is examined according to the procedure of steps S22 to S38. With respect to the line 3 as well, 470 pieces of the type 2 have already been assigned and the remaining production possible number is 130 pieces, which is less than the remaining production quantity of 200 pieces of the type 5. Therefore, step S2 in FIG.
By the processing of S2 and S26, 130 of the remaining production numbers of the type 5 are assigned to the line 3 (FIG. 12), and the line 4 in the next line order (third place) is examined. . Since the line 4 has 600 remaining productions, which is more than 70 productions of the type 5, the steps S22 and S2 in FIG.
By the process of No. 4, all the remaining 70 productions of the type 5 are allocated to the line 4, and the allocation of the type 5 is completed (FIG. 1).
2).

Similarly, for the subsequent type 6, after 250 pieces which can be assigned to the line 2 in the first line order are assigned, the line 3 in the second line order is considered. Since the remaining producible number of line 3 is 0, step S2 of FIG.
If NO is determined as 0, the process proceeds to step S36, the process returns from step S38 to step S18, and the line 5 in the third line order is considered. Then, all the remaining 50 productions of type 6 are assigned to the line 5 (FIG. 13). For the next type 7, since line 2 in the first place in the line order and line 3 in the second place are all full, line 4 in the line order 3 is considered. Number of remaining production on line 4 53
Since 0 pieces are larger than the total production quantity of 280 pieces of type 7, all production quantities are assigned to the line 4 (see FIG. 1).
4).

Subsequently, allocation for type 8 is performed. First, since line 3 in line order 1 is already full, line 5 in line order 2 is considered, and
By the process of step S26 of
Of the 0 pieces, only the remaining producible quantity of 130 in line 4 is allocated (FIG. 15). Next, steps S36 and S38.
Returns to step S18, and line 1 is the third place in line order.
Will be examined. However, since line 1 is already full, it is determined to be NO in step S20, and the process proceeds to step S36. Here, by the processing of step S36, the fourth line order is designated as the line order L1 to be examined next. However, since there are only three lines that can produce the type 8, the determination in step S38 is YES, the process proceeds to step S40, and the reallocation process shown in FIG. 5 is performed.

In other words, in step S52 of FIG. 5, the line (DL
(J) ≧ 1 j) is specified (first if there is more than one), and that line is designated as line JA. In the case of the present embodiment, as shown in FIG. 15, only the line 4 whose remaining producible number is not 0 is the line 4, and the line 4 becomes the line JA. Next, steps S54, S56 in FIG.
Types 1 to 7 already assigned by the processing of S58
However, the items are examined in descending order of sort order. First, according to steps S54 and S56, type 7
Is set as the type IB, and whether or not the type 7 can be produced on the line JA (= 4) is determined in step S58. Since the type 7 can be produced on the line 4, this determination is YES, and in step S60, S62, S70, S72, for each line that can produce the type 7 and is higher in line order than the line JA, the line order is lower. It will be examined from the beginning.

The line order for type 7 of line 4 is 3
Since it is the rank, the line 3 for the type 7 is the second in the line order, and the line 2 for the first rank is the target for consideration. However, as shown in FIG. 15, these lines 2, 3
Since the type 7 is not assigned to any of the above, the determination in step S62 of FIG. 5 is NO. Then, when the line 2 of the first place is examined, the judgment result of step 72 is also YE.
Since S, the steps S74, S76 to S
Returning to 56, the assigned type 6 having the next lowest sort order is examined. However, since the type 6 cannot be produced on the line 4, the determination in step S58 is NO, and the process proceeds to the examination of the type 5 in the previous order. Type 5
Can be produced on the line 4, so as with the case of the type 7, another line on which the type 5 can be produced is examined.
First, the line 3 in the second place in the line order is considered, and the determination in step S62 for the line 3 is YES. Therefore, after proceeding to step S64 and the line 3 is designated as the line JC, the reallocation process in step S66 is executed.

That is, the number of types 5 produced on the line 3 is reduced by the remaining 70 available for production of the type 8 which is currently unassignable, and the number of types 5 produced on the line 4 is increased accordingly. . As a result, the production allocation in line 3 of type 5 is 60, and the production allocation in line 4 is 140. In line with this, the remaining production capacity of line 3 is 7
The number of remaining producible lines 4 decreases by 0, and decreases by 70 (step S66 in FIG. 5). After this processing, the processing is returned from step S68 in FIG. 5 to step S18 in FIG. 4, and the normal allocation is resumed for the type 8 that cannot be allocated during the allocation processing. Then, since the remaining producible number of the line 3 which is ranked first in the line order is 70 this time, both the determinations in steps S20 and S22 are YES, and the remaining producible number of type 8 of 70 is assigned to the line 3 in step S24. (FIG. 16). In this way, the allocation of type 8 is completed, and the allocation of types 9 and 10 is further performed.

For the type 9, all 130 production numbers are assigned to the line 4 which is ranked first in the line order (FIG. 17) by the normal assignment procedure (FIG. 4). But type 10
About production line 5, line 2, line 1
Are all full and cannot be allocated by the normal procedure (FIG. 18). Therefore, as in the case of type 8, the reallocation process is executed according to the procedure of FIG. Specifically, after the production number 50 of type 5 is transferred from line 1 to line 4, the production number 50 of type 10 is assigned to line 1 (FIG. 19). By the above procedure, all the production numbers of types 1 to 10 to be produced are
~ Is assigned to line 5, and the assignment result shown in FIG. 20 is obtained. In this way, according to the production allocation instructing device 2 of the present embodiment, accurate production in a system for producing a plurality of types of articles (types 1 to 10) on a plurality of production lines (lines 1 to 5). Assignment (Fig. 20)
Can be automatically determined and instructed in a short time.

In this embodiment, the number of kinds of articles to be produced is 10 and the number of production lines is 5, but
It goes without saying that the number of types of goods and the number of production lines are not limited to these. Further, in the present embodiment, the item type number i and the type order W (i) are all matched, but they need not match. Starting with the production allocation instruction device, the structure of other parts such as the multi-product production system and production line,
The shape, size, material, quantity, etc. are not limited to those in this embodiment.

[0030]

According to the present invention, when the allocation according to the normal priority order is impossible, the production allocation instructing device is characterized in that an appropriate kind is re-allocated from the allocated kinds. Therefore, it is possible to automatically determine and instruct an accurate production allocation in a system that produces a plurality of types of articles on a plurality of production lines in a short time. With this accurate production allocation, a plurality of types of articles can be efficiently produced on a plurality of production lines, and the device becomes a very practical production allocation instruction device.
