There is provided a method of manufacturing a product characterized in that it is performed.

  According to the present invention, a product manufacturing support system, a product manufacturing system, a product manufacturing support method, and a product manufacturing method capable of determining the priority of the start of a manufacturing lot based on the delivery date and the manufacturing progress level Is provided.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram for illustrating a product manufacturing support system 1 according to an embodiment of the present invention.
As shown in FIG. 1, an input unit 2 and an output unit 3 are electrically connected to a product manufacturing support system 1. Further, it can be electrically connected to an online controller 21, manufacturing condition storage means 22, manufacturing apparatuses 23a, 23b, and 23c (see FIG. 6), which will be described later, and various data can be exchanged.

  The product manufacturing support system 1 includes a speed magnification calculating means 1a for calculating a speed magnification, which will be described later, and a priority determination for determining the priority of starting a production lot based on the speed magnification calculated by the speed magnification calculating means 1a. Means 1b.

  According to the speed magnification calculated by the speed magnification calculating means 1a, it is determined whether or not the production is progressing as planned with respect to the production plan that is completed and paid out from each production apparatus or production line. be able to. This speed magnification can be calculated for each production lot. Details of the speed magnification will be described later.

The priority determination means 1b determines the priority of the start of a plurality of production lots based on the speed magnification calculated by the speed magnification calculation means 1a.
The speed magnification calculation means 1a and the priority determination means 1b can be, for example, a module provided in a central processing unit (Central Processing Unit) or a program that can be executed on the central processing unit (Central Processing Unit).

For example, the input means 2 is for inputting information directly such as a keyboard and a mouse, and for inputting information via a recording medium such as a flexible disk device and a CD-ROM device. can do.
The output means 3 can be, for example, a flat panel display device or a printer device provided with a liquid crystal display panel or the like.
Note that the input means 2 and the output means 3 are not always necessary and can be omitted. Further, it is not necessary to be directly connected to the product manufacturing support system 1. It is also possible to input information or to output various information and commands to output means provided in the online controller 21, manufacturing condition storage means 22, manufacturing apparatuses 23a, 23b, 23c (see FIG. 6), etc. it can.

ここで、Ｓは速度倍率である。 Next, the speed magnification will be described.
The speed magnification can be calculated for each production lot, and can be calculated by the following equation (1).

Here, S is a speed magnification.

  For convenience of explanation, a case will be described in which the remaining work period (A) until delivery date and the remaining work period (B) required before delivery are calculated by “number of days” and the speed multiplication factor is calculated, but the delivery date and product work period are short. In the case of a thing, or conversely a long thing, it can also be set as the calculation by other units like the number of hours, the number of years, etc. instead of "days".

  In the speed magnification calculated by the equation (1), if S <1, it indicates that the manufacturing progress is more advanced than the production plan, and if S = 1, it indicates that the manufacturing progresses as per the production plan. , S> 1 indicates that the manufacturing progress is behind the production plan.

  In this case, for example, if the speed multiplication factor S of a certain production lot is “2”, it indicates that the remaining days until the delivery date is only half of the remaining work days required until the delivery. Therefore, it turns out that manufacture of the said production lot must progress at a speed twice with respect to the remaining work period. Here, the “manufacturing lot” may include only one product or may include a plurality of products. Further, the “production lot” may consist of only a single product type, or may include a plurality of product types.

FIG. 2 is a schematic graph for illustrating the concept of speed magnification.
As shown in Fig. 2, if the vertical axis is the work period and the horizontal axis is the delivery time, manufacturing progresses according to the production plan if the slope connecting the work period and delivery time determined by the production plan etc. is on a straight line of 45 degrees. (S = 1). And the thing below the straight line shows the case where the progress of manufacturing is progressing more than the production plan (S <1), and the thing above the straight line shows the progress of the manufacturing behind the production plan. The case (S> 1) will be indicated.

  As described above, it is possible to make up for manufacturing delay by calculating the speed magnification for each production lot and preferentially starting the work with a larger value of the speed magnification. Also, if the production lots that are progressing in production are not made to progress more than necessary, the production lots can be distributed to other production lots that are behind production, so the overall delay is minimized. Optimal manufacturing can be performed.

  Theoretically, the delivery date can be observed even if the production quota for the day is set and the production progress of the production lot is managed. However, the progress of manufacturing lots is not always optimal. For example, the manufacturing progress of each manufacturing lot may not be properly distributed due to a failure of the manufacturing apparatus, generation of a defective manufacturing lot, change of the delivery quantity or manufacturing conditions, and the like.

FIG. 3 is a schematic graph for illustrating the relationship between the speed magnification and the appropriate inventory.
The horizontal axis represents “process progress”, and the more the production lot “input” at the origin moves to the right, the more the manufacturing progresses and finally “payout” is performed. The vertical axis represents “in-process inventory quantity” (the number of production lots being produced).

  The broken line in the figure represents “appropriate inventory”, and indicates that “in-process inventory quantity” decreases as the manufacturing progresses from “injection” to “dispensing”. Further, if it is on the broken line in the figure, it represents a state of “proper inventory”, that is, a state in which manufacturing is progressing according to the production plan. On the other hand, the one below the broken line represents the case where the manufacturing progress is ahead of the production plan, and the one above the broken line represents the case where the manufacturing progress is behind the production plan. . The solid line in the figure represents the actual inventory status.

  In actual manufacturing, for example, due to a failure of a manufacturing device, generation of a defective manufacturing lot, etc., it does not necessarily become an “appropriate inventory” state, and manufacturing is delayed as shown by a solid line in FIG. What is going on will be mixed.

  In the present embodiment, the speed multiplication factor is calculated for each production lot, and the production delay closes by making the production lot with a high speed multiplication the priority, and the production close to “proper inventory” Can be done. For example, by preferentially starting the work on the upper side of the broken line in FIG. 3, the delay in the production of the production lot in the part can be recovered and brought closer to “appropriate inventory”.

  Moreover, it is possible to perform production close to “appropriate inventory” by preventing a production lot in which the production progress is progressing from being made more than necessary. In addition, since the remaining production capacity can be allocated to a production lot in which the progress of production is delayed, the whole can be brought close to “appropriate inventory” quickly. For example, if the portion below the broken line in FIG. 3 is not progressed more than necessary, the production lot in that portion can be brought closer to the “appropriate inventory”. In addition, since the production surplus generated by delaying the production of the production lot in the portion can be directed to the one on the upper side of the broken line, the whole can be brought close to “appropriate inventory” quickly.

  In this case, since the speed magnification can be calculated by a very simple calculation formula like the formula (1), the calculation can always be performed, and the real-time start priority can be determined. For this reason, it is possible to greatly improve the accuracy of determination of the priority of construction and the responsiveness. Since the calculation formula is simple, it is possible to reduce the load on the speed magnification calculating means 1a even if constant calculation is performed.

  In addition, since the rate of change increases as the speed magnification approaches the completion (payout) from the input, the work closer to the completion (payout) is started, and the responsiveness to the delivery date can be improved.

  In addition, since the priority of the construction can be quantified by the speed magnification and the calculation can also be made by a very simple calculation formula like the formula (1), it is widely used for manufacturing various production lots. Can be applied.

FIG. 4 is a flowchart for illustrating a speed magnification calculation method by the speed magnification calculation means 1a.
As shown in FIG. 4, a “remaining work period until delivery date (A)” is calculated based on the difference between the “production plan” and the “current time”. Also, based on the difference between the predetermined number of processes, the number of work days, etc., and the “inventory information” (current production status of the production lot) that represents the progress of production provided by each production device etc. The remaining work period (B) necessary for the calculation is calculated. The “current time” can be obtained from a clock (not shown) provided in the manufacturing support system 1 or can be obtained from information relating to time input from the outside. Further, the “production plan”, the predetermined number of processes, the number of work days, and the like can be input from the input unit 2 or can be provided from the manufacturing condition storage unit 22 or the like. Further, “inventory information” can be provided from each manufacturing apparatus or the like.

  Then, as shown in the equation (1), the speed magnification S is calculated from the “remaining work period until delivery date (A)” and the “remaining work period required before paying out (B)”. The speed magnification S is obtained for each production lot, and they are sorted to determine the priority of construction, and production is performed based on the priority. By doing so, as described above, it is possible to make up for the delay in manufacturing the manufacturing lot and to perform efficient manufacturing close to “appropriate inventory”. Moreover, since the speed magnification can be obtained by a very simple calculation, the priority of the start of construction can be managed in real time.

FIG. 5 is a flowchart for illustrating a method of calculating a speed magnification according to another embodiment.
Depending on the production lot to be manufactured, there may be many varieties and processes. In such a case, if it is possible to directly know the information on each product type and the process for them, the computation can be prevented from becoming complicated.

  In the present embodiment, it is possible to know information related to delivery date from “production plan”, identification of a production lot in the manufacturing process from “product name information”, and current production status of the production lot from “inventory information”.

  And it ranks in the order close to payout of a manufacturing process from these information. In this way, if prioritization is performed by prioritizing (assigning) from the ones close to the payout (completion) where it is difficult to recover the delay, it is possible to level the manufacturing delay.

Next, for the items ranked in the order closest to the payout, the “remaining work period until delivery date (A)” is calculated based on the difference from the “current time”.
On the other hand, based on the difference between the scheduled work period in each process from “process information” and the current production state (work period) of the production lot from “inventory information”, “remaining work period (B) required until delivery” Is calculated.

  The “current time” can be obtained from a clock (not shown) provided in the manufacturing support system 1 or can be obtained from information relating to time input from the outside. Further, “production plan”, “product name information”, “process information”, and the like can be input from the input unit 2 or can be provided from the manufacturing condition storage unit 22 or the like. Further, “inventory information” can be provided from each manufacturing apparatus or the like.

  Then, as shown in the equation (1), the speed magnification S is calculated from the “remaining work period until delivery date (A)” and the “remaining work period required before paying out (B)”. The speed magnification S is obtained for each production lot, and these are sorted to determine the priority of the start of construction, and production is performed based on the priority. By doing so, as described above, it is possible to make up for the delay in manufacturing the manufacturing lot and to perform efficient manufacturing close to “appropriate inventory”. Moreover, since the speed magnification can be obtained by a very simple calculation, the priority of the start of construction can be managed in real time.

  Next, the start priority determination performed in the priority determination means 1b will be described. The priority determination means 1b determines the priority of the start of each production lot based on the speed magnification calculated by the speed magnification calculation means 1a. At this time, it is determined that the construction is prioritized from the one with the larger value of the speed magnification.

  It should be noted that the “remaining work period (A) until delivery” and the “remaining work period (B) necessary until delivery” are not normally negative values. However, for example, when an abnormal situation (failure of the manufacturing apparatus) occurs and the “overtime until delivery date (A)” becomes a negative value, the value of the speed magnification is small (negative value). Nevertheless, the production of the target production lot can be preferentially performed. At this time, it is possible to prevent the “remaining work period until delivery date (A)” from becoming a negative value even if an abnormal situation occurs by reviewing the “production plan” as necessary.

Here, a procedure in the case where there is a change in the production plan with respect to a fluctuation in the capacity of the manufacturing apparatus will be exemplified. For example, when the manufacturing capability is improved because a new type of manufacturing device is introduced, or when the manufacturing capability is reduced because a part of the manufacturing device is broken, information on the delivery date of the “production plan” is changed.
Based on the “production plan” in which the information related to the delivery date is changed, ranking is performed in the order close to the payout of the manufacturing process.
Next, for the items ranked in the order closest to the payout, the “remaining work period until delivery date (A)” is calculated based on the difference from the “current time”.
On the other hand, based on the difference between the scheduled work period in each process from “process information” and the current production state (work period) of the production lot from “inventory information”, “remaining work period (B) required until delivery” Is calculated.
Hereinafter, as described above, the speed magnification S is obtained by calculating the speed magnification S from the “remaining work period until delivery (A)” and the “remaining work period required before delivery (B)”, and obtained for each production lot. Then, the priority of the construction is determined, and the production is performed based on the priority.
In this way, even when there is a change in the production schedule due to a change in the capacity of the manufacturing device, etc., and there is a change in the “production plan”, it is possible to make up for the delay in manufacturing the manufacturing lot. Efficient production close to “appropriate inventory” can be performed.
Further, since the speed magnification can be obtained by a very simple calculation, it is possible to manage the priority of the start of construction in real time even for an unexpected change caused by a failure of the manufacturing apparatus.

If the speed magnification is used as described above, real-time management can be performed. Therefore, for example, the occurrence of the above-described abnormal situation can be predicted by a rapid increase in the speed magnification.
It is also possible to provide a predetermined threshold value for the speed magnification and review the “production plan” when the predetermined threshold value is exceeded for a predetermined period or a predetermined number of times.

Next, a target production lot is sent to the manufacturing apparatuses 23a, 23b, and 23c by a transfer device (not shown) based on the priority data of the start of the process, and processing and processing based on manufacturing condition data (recipe data) are performed. Is called.
At this time, the online controller 21 sends data such as process progress status and operation status from the manufacturing apparatuses 23 a, 23 b, and 23 c to the manufacturing support system 1.

Further, the priority of the construction is judged based on the calculated speed magnification, and the data of the construction priority is changed if necessary. Then, the online controller 21 sends start priority data changed from the manufacturing support system 1 to a transport apparatus and manufacturing apparatuses 23a, 23b, and 23c (not shown).
