DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a delivery instruction method and a delivery instruction system for necessary parts in a production factory, and in particular, a multi-company delivery instruction management method for issuing a delivery instruction of the same kind of parts to a plurality of parts factories And a multi-company delivery instruction management system.

[0002]

2. Description of the Related Art Hitherto, as an important factor for improving the efficiency of product production management in a factory, there is management of parts procurement. In the production process, if the necessary parts are insufficient, the production cannot be performed. Therefore, the shortage of the parts must be avoided as much as possible. On the other hand, having parts unnecessarily in stock
Problems arise, such as the need for extra inventory space.
Therefore, it is desirable to procure parts that satisfy both of these requirements and that do not cause stockouts with minimum inventory. In particular, in the case of products manufactured using a large number of different parts, such as automobiles, it is very important to efficiently procure the parts.

[0003] As such a parts procurement method, there is a procurement method called a "kanban" method. In this method, on the premise that consumed parts are consumed again,
For example, a delivery instruction is given to a part instructed to be delivered to each parts factory on a monthly basis based on the planned usage of the parts by using a delivery timing instruction card (hereinafter referred to as a kanban) for instructing a delivery timing. That is, the kanban delivered to the production factory together with the parts (normally, the parts are packed in a box, and one part box and one kanban correspond), by using the parts,
Removed from parts box. Therefore, the lost Kanban is collected, put on a delivery instruction flight at a predetermined frequency, and sent to a parts factory ( delivery order).
Carry to indicate the destination). Here, the return flight of the normal delivery flight is used as the delivery instruction flight. Then, the parts ordered by the kanban are delivered from the parts factory to the production factory by delivery service. That is, the cycle of replenishing only used parts is repeated.

On the other hand, when a production factory receives parts from a parts factory, a plurality of parts factories (for example, A
Company, Company B, Company C, Company D). When parts are used in the production process, parts in each parts factory are not always used uniformly, but may be used unevenly. In this case, if the parts used are returned to the same manufacturer as they are and delivery instructions are given, the amount of delivery instructions will vary significantly depending on the usage of the parts. However, there arises a problem that a situation occurs in which only the company C is used, or there is a parts factory in which the delivery instruction is practically canceled because it is not used at all. Therefore, the person in charge of the parts delivery instruction determines the parts delivery instruction ratio from the experienced side, taking into account the production plan and the capabilities of the parts factory that are regularly created, and sorts out kanbans based on the delivery instruction ratio. They instructed each parts factory to deliver parts.

[0005] A conventional distribution will be described with reference to a processing table shown in FIG. For example, the delivery destination company A has 10 pieces of parts (the number of pieces) to be delivered with one kanban.
The set delivery instruction ratio is 10, and the delivery instruction destination company B has a capacity of 5 and the delivery instruction ratio is 12. Hereinafter, the same setting is performed for Company C and Company D.
When an out-of-order kanban occurs, the out-of-order kanban is distributed to the delivery instruction destination with the smallest distribution ratio (comparison number / delivery instruction ratio) determined by the delivery instruction ratio and the comparison number (the initial comparison number is all 0). Is performed. If the distribution ratios are the same, the distribution is performed to the larger (comparison number / accommodation number). If the distribution ratios are still the same, the distribution is performed to the larger delivery instruction ratio. When the kanban distribution is performed, the number of stored items is added to the number of comparisons.
The distribution ratio displayed in (delivery instruction ratio) is updated.

As shown in FIG. 6, when the first piece of kanban is generated, the distribution ratio is compared. In the case of the first one,
Since the number of comparisons is 0 for all companies, the distribution destination is determined for the company B having the largest delivery instruction ratio, 5 is added to the comparison number of the company B, and the distribution ratio is updated. When the second piece of kanban occurs, a comparison is made between companies A, C, and D with a distribution ratio of 0, and the distribution destination is determined to be the company A with the highest delivery instruction ratio, and the comparison of company A is performed. The number 10 is added, and the distribution ratio is updated. The same applies to D and C companies. At the time of the occurrence of the fifth outlying kanban, the distribution ratio can be compared, and the distribution destination is determined to the company B having the smallest distribution ratio. Company B, D at the time of the 8th outlying kanban
The distribution destination is determined for Company B, which has the same distribution ratio at the minimum but has the same (comparison number / accommodation number). in this way,
The distribution destination is determined sequentially. For example, even if only company A has 10 outbreaks, or if only company C has 10 outbreaks, company A has two, company B has five, company C has one, and company C has one.
The company distributes two sheets and distributes out-of-order kanbans in accordance with the delivery instruction ratio, thereby avoiding the situation where the delivery instruction is only for company A in the first half of the month and only for company C in the second half of the month. can do.

[0007]

However, in the conventional multi-company delivery instruction management method, since the delivery instructions are distributed based on the number of out-of-order kanbans, 100 parts are used and the kanban of company A is used. If 10 pieces are missing and 50 pieces are used and 10 pieces of KANBAN of Company B are removed, the kanban distribution is performed as described above, and the total number of parts newly ordered is 65 pieces. However, the number of parts actually used in the production process is not reflected in the delivery instruction, and there is a problem that the number of parts is excessive or insufficient.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and when a delivery instruction is given to a multi-company delivery destination, the delivery instruction ratio is actually used in the production process in accordance with the delivery instruction ratio. It is an object of the present invention to provide a multi-company delivery instruction management method and a multi-company delivery instruction management system capable of giving an efficient multi-company delivery instruction with less variation in the delivery instruction amount by reflecting the number of parts.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings.

The delivery timing instruction card (hereinafter, referred to as “kanban”) used in the present embodiment includes a delivery instruction destination (parts factory), a delivery destination (production factory), a product name, a product number, a kanban cycle described later, a number to be accommodated, and the like. The parts factory prepares the delivery in accordance with the kanban, and delivers the kanban together with the parts to a parts transport box or the like. When the parts are used in the production process, the kanban is removed from the parts transport box or the like and becomes the input information sheet for the multi-company delivery instruction processing.

FIG. 1 is realized by computer processing .
That Fukusha an explanatory diagram for explaining a configuration of a delivery instruction management system, double this in the management system, which is a processing table for performing data or Fukusha delivery instruction processing such as production capacity and delivery cycle for each parts plant A multi-company delivery instruction master 10 that stores a company delivery instruction file (to be described later), a kanban 2 format that actually performs the delivery instruction (for example, data on the part number type and the number of parts to be stored), and a multi-company delivery instruction is possible. A kanban master 12 in which data such as the group of the kanban 2 is stored is provided. Multi-company delivery instruction master 1
The zero and kanban master 12 is a database that can be updated each time data of a part to be instructed to be delivered by multiple companies is added.
Further, in the management system, the input information input based on the kanban 2 in which the part is used and removed from the parts transport box or the like, that is, the so-called “outside kanban” and the multi-company delivery instruction processing are completed, and the new kanban 2 is completed. A kanban reading result file 14 is provided for storing output information and the like provided when creating a.

FIG. 2 shows an example of the multi-company delivery instruction file 16 in the multi-company delivery instruction master 10. The multi-company delivery instruction file 16 is of the same type of parts that can be delivered to multiple companies (part numbers differ for each part factory, shapes and specifications are slightly different, but they can be used as the same part, regardless of the delivery destination) Are grouped together as a group, and the "delivery instruction destination", "accommodation number", "kanban number of rotations", "kanban cycle", "delivery instruction ratio", "appearance tendency value", "delivery instruction tendency value", "delivery instruction value""Surplus","necessary number of parts",
"Distribution number" and the like are described. The delivery instruction destination is A
Shows the parts factories of Company B, Company C, Company D, etc.
The number of parts to be delivered in one kanban 2 is shown. Also,
The number of kanban rotations indicates the number of kanbans circulating between the delivery destination and the delivery destination, and the kanban cycle indicates the function of the kanban. In the case of the kanban cycle abc, it indicates that there are b delivery instructions in a day a, and that parts are delivered after the c flight counted from the delivery instruction. The kanban rotation number M can be calculated by the following equation.

M = {N · h / m} · {a (c + 1) / b} (Equation 1) Here, N is a required number per day, h is a ratio setting to the required number per day, and N is set. H% of the required number per day
Means delivery to a specific parts factory. M is the number of stored parts. The required number N per day, the comparison setting h, and the like are values determined based on a production plan created every predetermined period, for example, every month. Is delivered after c flights, but taking into account the lead time from the delivery location to the line where the parts are actually used (c + 1)
It is what it was.

The delivery instruction ratio H representing the ratio of the number of kanbans issued per day to a predetermined parts factory for delivery instructions can be calculated by the following equation.

H = N · h / m = M · b / {a (c + 1)} (Equation 2) The appearance tendency value represents the expression of the delivery instruction ratio such that the sum total becomes 1 in the delivery instruction destination group. The delivery instruction tendency value is a value that can be updated based on the appearance tendency value each time one kanban is assigned, and the kanban 2 is assigned to the parts factory having the largest delivery instruction tendency value. . Note that the sum of the delivery instruction tendency values is also updated so as to always be 1. Delivery surplus is the number of parts that were ordered to be delivered extra in the previous delivery. Usually, to prevent parts shortages,
Delivery adjustment is performed so that the delivery surplus ≧ 0. Also,
The required number of parts indicates the number of parts currently required to be delivered in consideration of the surplus of delivery, and the number of distributions indicates the final delivery instruction distribution state in the delivery destination group.

An actual multi-company delivery instruction management system will be described below using the flowchart of FIG. 3, the processing table of FIG. 4, and the multi-company delivery instruction file of FIGS.

As shown in the main flowchart of FIG. 3A, when a part is used in a production process of a factory and a departure kanban 2 occurs, the system sequentially operates the departure kanban 2.
Are read and stored in the kanban reading record file 14 (S1: card reading step). Various data are displayed on the kanban 2 and the same data is also displayed by a symbol such as a bar code, which can be easily recognized by reading it with a reading device. In addition, reading of Kanban 2
It may be carried out every time an outlying kanban occurs or may be carried out collectively every predetermined time. When the sorting process is actually started, the kanbans 2 which can be distributed and delivered to a plurality of companies are selected from the read kanbans 2 and the number of kanbans for which the multi-company delivery is to be instructed is determined (S2: card selection step). .

Next, a kanban master 12 is searched for a multi-company delivery instruction possible group including the determined kanban 2 (S3), and a multi-company delivery instruction file 16 corresponding to the retrieved multi-company delivery instruction possible group is searched for by the multi-company delivery. Delivery instruction master 10
(S4). Then, the total number of parts described in the kanban 2 selected in the card selecting step (S2), that is, the number of parts to be delivered is calculated (S2).
5: part number recognition step). For example, in the case of the first sorting process after the change of the production plan, if two kanbans of company A with a capacity of 10 are selected and two kanbans of company B with a capacity of 5 are selected, the number of parts to be delivered is 30. Individual. When the calculation of the number of parts to be delivered is completed, a distribution calculation subroutine shown in FIG. 3B is entered (S6). In the distribution calculation subroutine, the number of parts additionally delivered in the previous delivery instruction is subtracted from the number of parts to be delivered, and the number of parts actually required to be delivered (the number of required parts) is calculated (S6-1: Required number calculation step). However, in the case of the first delivery instruction processing, the delivery surplus is zero. Next, it is determined whether or not the required number of parts is larger than 0 (S6-2). If it is larger than 0, the delivery instruction tendency values of the respective companies are compared to determine the parts delivery instruction destination. When determining the distribution destination of the first kanban 2, the delivery instruction tendency value uses the appearance tendency value based on the delivery instruction ratio as it is (trend calculation step), and the delivery instruction tendency value group is determined by the delivery instruction tendency value of each company. Form. For example, the delivery instruction tendency value group used to determine the distribution destination of the first kanban 2 is 0.36,0 .0 shown in (first group) in FIG.
43, 0.07, and 0.14. One kanban 2 is sorted to the parts factory having the largest delivery instruction tendency value among the delivery instruction tendency groups, that is, Company B having the delivery instruction tendency value of 0.43.
The distribution number of the company B is updated (S6-3: delivery instruction destination determination step).

After the distribution destination of the kanban 2 is determined, each appearance tendency value is added to each delivery instruction tendency value, and the delivery instruction tendency value of the parts factory (company B) determined in the delivery instruction destination determination step is determined. Is subtracted from the total, ie, 1 to obtain a new delivery instruction tendency value group (S6).
-4: trend value group updating step). That is, (second
0.72, -0.14, 0.14, 0.28
Becomes a new delivery instruction tendency value group. Further, the determined number of parts of the delivery instruction destination (company B) determined in the delivery instruction destination determination step is subtracted from the required number of parts to obtain a new required number of parts (S6-5: required number update step).
That is, the new required number of parts is 25. Then, returning to (S6-2), it is determined whether or not the required number of parts is greater than 0, and the delivery instruction destination determination step (S6-
3) Execute the tendency value group updating step (S6-4) and the required number updating step (S6-5), determine the allocation destination of the kanban 2 sequentially, and repeat until the required number of parts becomes 0 or less (S6- 2 to S6-5: repeated steps).

When the required number of parts is 0 or less, that is, when the delivery instruction amount is performed by a desired number or exceeds the desired number, it is recognized as a delivery surplus, and the delivery surplus data of the multi-company delivery instruction file 16 is recognized. Is updated (S6-6). In the case of this embodiment, the number of delivery instructions is 25 at the time of distribution of the fourth kanban, and the remaining five delivery instructions are required. Then, when the repetition steps of (S6-2 to S6-5) are executed, as shown in (fifth group), kanban distribution is performed to Company A, and ten delivery instructions are performed. Therefore, 35 delivery instructions have been issued, and five delivery surpluses are generated, and the data on the surplus delivery in the multi-company delivery instruction file 16 is updated in preparation for the next multi-company delivery instruction process. FIG. 5A shows the multi-company delivery instruction file 16 at this time.
It is. When the delivery surplus is updated, the distribution calculation subroutine ends, and the process returns to the main flowchart of FIG. 3A, and the kanban result file 14 is written based on the kanban distribution result of the present multi-company delivery instruction processing. Is performed (S7), and the first double-company delivery instruction process ends. After that, when a predetermined delivery instruction timing comes, a delivery instruction is issued to each parts factory based on the distributed kanban (delivery instruction step).

After the first multi-company delivery instruction processing, one new kanban of Company A with 10 accommodations, two Kanbans of Company B with 5 accommodations, and a new kanban of 5 Company B One kanban from the company is selected (S2), and through (S3 to S4),
When the multi-company delivery instruction file 16 described above is read and the kanban distribution process is started, the number of parts to be delivered becomes two.
There are five (S5), and the assignment calculation subroutine (S6)
Is executed. In the first multi-company delivery instruction process, there are five delivery surpluses, so in the required number calculation step (S6-1), five delivery surpluses are subtracted from 25 parts to be delivered, and the actual delivery instruction is required. The required number of parts 20 is calculated.

In the same manner as in the first multi-company delivery instruction processing, the distribution of the kanbans 2 is performed until the required number of components becomes 0 or less. FIG. 5B shows a multi-company delivery instruction file 16 showing the result of the second multi-company delivery instruction process. In addition, FIG.
In the first multi-company delivery instruction process, a delivery instruction is issued to each company, and the number of kanbans to be distributed shows only the result of the second multi-company delivery instruction process. If the delivery instruction is not issued in the first time, the number of sorted sheets is displayed by adding the result of the second time to the result of the first time. Thereafter, the kanban performance file 14 is rewritten in the same manner as described above, and waits for the delivery instruction or the start of the third multi-company delivery instruction processing.

As described above, in this embodiment, the delivery instruction destination is determined in accordance with the required number of parts based on the number of parts described in the delivery timing instruction card provided with the consumption of parts and the ratio of each company's delivery instruction. In addition, it is possible to prevent a bias in parts delivery instructions and an excessively short or excessive amount of parts delivery instructions.

[0027]

As described above, according to the multi-company delivery instruction management method and the configuration of the multi-company delivery instruction management system of the present invention, the contents of the delivery timing instruction card provided with the consumption of parts are read. From among them, select a delivery timing instruction card that can direct distribution delivery to multiple companies,
The number of parts to be delivered described in the selected delivery timing instruction card is recognized. Then, the number of surplus parts in the previous delivery instruction is subtracted from the number of parts to be delivered this time, and the number of parts actually required in this delivery is calculated.
On the other hand, a renewable delivery instruction tendency value group based on the appearance tendency value based on each company delivery instruction ratio is calculated, and if the required number of parts is greater than 0, the largest one of the delivery instruction tendency value groups is delivered. Determined as the instruction destination. Next, the determined number of parts of the delivery instruction destination determined earlier is subtracted from the required number of parts, the required number of parts is updated, and the appearance tendency value is added to each of the delivery instruction tendency value groups, and the number is determined first. Then, the sum of the appearance tendency values is subtracted from the delivery instruction tendency value of the delivery instruction destination, thereby obtaining a new delivery instruction tendency value group. Then, based on the updated delivery instruction tendency value group, the delivery instruction destination determination process, the required number update process, and the tendency value group update process are repeatedly executed to sequentially determine the delivery instruction destination. Then, when the required number of parts becomes 0 or less and a predetermined delivery timing comes, the delivery instruction of the parts is performed to the delivery instruction destination which has been determined. Therefore, the delivery instruction destination is determined according to the required number of parts based on the number of parts described in the delivery timing instruction card provided with the parts consumption and the ratio of each company's delivery instruction. It is possible to prevent excess or deficiency of the delivery instruction amount and to efficiently issue the delivery instruction of the parts.
