Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printed matter manufacturing process control system.

[0002]

2. Description of the Related Art In general, when a printed matter for a certain item is produced, a production plan for plate making and printing is drafted after the order for the item is confirmed. This type of production plan needs to be promptly planned and transmitted to the work department with appropriate contents from the viewpoint of finishing the ordered items by the delivery date while maintaining a certain quality.

On the other hand, since there are various kinds of printed matter,
Each process from submission to delivery is not uniquely determined. Therefore, the production plan of the printed matter is drafted after the delivery date, the quality, the stock, the department in which the work is developed, the optimization, and the like are sufficiently taken into consideration. Here, in order to specifically instruct each department of work, it is necessary for an expert who is familiar with all processes to issue a production plan within a short time.

Even after the production plan is issued, the negotiation with the customer is usually continued while the schedule and layout are corrected every moment. When such a correction is made, the production plan is drafted again, the work instruction is changed and sent to each department regardless of the work efficiency. Upon receiving this work instruction, each department carries out an unreasonable change even if the work efficiency is lowered, and works in time for the delivery date.

By the way, the manuscript of the printed matter is written as digital data in a storage medium such as a floppy disk or a magneto-optical disk due to the progress of the electronic technology in recent years, and is handled by each department via this kind of storage medium. The number of cases is increasing.

[0006]

However, in the manufacturing process management system as described above, in the case of a digitized manuscript, it is possible to easily update, copy, transfer, and delete data by using a computer, while the data can be updated. Since it is difficult to grasp the management information such as the distribution route and the processing history of the product, there is a problem that it is changed unlike the original intention, which causes an increase in defective products. Moreover, since the analysis result of the production results is not used in the process of drafting the production plan, the consistency between the planned production plan and the actual production result is low.

As a method of making a production plan of this kind, a process is centrally managed to make a production plan, and the production plan is distributed to each department via a network. Then, each department makes a production plan. It is conceivable that the production performance data is collected and the progress status of the process is grasped by correspondingly returning the production performance, and thus the production plan and the production performance are matched. However, in this method, a production management expert compares the production plan with the production performance and examines the consistency, and based on the result of this examination, the planning process of the future production plan is modified. It will be very laborious.

The present invention has been made in consideration of the above-mentioned circumstances, and a manufacturing process capable of making a production plan equivalent to the case of having an expert and improving reliability, even if there is no expert who is familiar with all the processes. The purpose is to be able to provide a management system.

A second object of the present invention is to provide a manufacturing process management system capable of accurately ascertaining the production performance of a planned production plan. Furthermore, a third object of the present invention is to correct the production plan from the next time onward so as to match the production record with the production plan, thereby improving the production efficiency while matching the production plan with the production record. It is to provide a manufacturing process control system that can improve the manufacturing process to the maximum.

When a reading request or a writing request is individually received from each of the terminals 1 to 6 of the printing terminal 6, based on the reading request or the writing request,
The database 9 has a function of reading or writing.

Next, the operation of the manufacturing process control system configured as described above will be described with reference to the flowcharts of FIGS. 6 and 7. (Drafting a Production Plan) Now, in the sales terminal 1, the order information including the item and the delivery date is input to the database management unit 8 by the operation of the operator (ST1).

The database management unit 8 registers this order information in the database 9 and, when the registration is completed (ST2), notifies the terminals 1 to 6 that the database 9 has been updated.

When the production management terminal 2 is notified that the database 9 has been updated, the latest order information and the process sequence, process name, and process quantity corresponding to the items in this order information are operated by the operator. The process information including the information and the production progress schedule table are read from the database 9 (ST3: planning means), and the production schedule data of the item is assigned to the production progress schedule table and set based on the order information and the process information. After that, the production schedule table for all items,
That is, a production plan is drafted (ST4: plan preparation means).

For example, as shown in FIG. 2, the production control terminal 2 reads out the process information corresponding to the item "leaflet for JJJ member" and, as shown in FIG. Assign each process from the final process to the starting process in the reverse order, set the production plan data,
As shown in FIG. 9, a production progress schedule table for the item is created, and the data of the production progress schedule table is given to the database management unit 8, so that as shown in FIG. Update the production schedule table for all items.

Next, the production management terminal 2 reads the load plan table for each process via the database management unit 8 and, based on the contents of the production progress schedule table of the item, stores these load plan tables. Update individually (ST
5). On the other hand, the production management terminal 2 reads the load calculation information in the database 9 corresponding to the schedule and process in the production progress schedule table of the item (ST6), and based on the load calculation information, for each date. An allowable load amount is calculated (ST7: work load determination means).

As shown in FIG. 11 (a), the production control terminal 2 compares the updated load plan table with the load allowable amount (ST8: work load determining means) to determine the total load amount for each date. By determining whether is lower than the load capacity,
It is determined whether or not the total load amount can be processed (ST9: work load determination means), and when there is a date when the total load amount cannot be processed, the current date is subtracted from the delivery date of each item on that date. Calculating the priority (ST10: priority order adding means),
As shown in FIG. 11 (b), after reducing the daily load of the item of low priority to reduce the total load of the date (ST11: plan correction means), the process returns to step ST9.

On the other hand, if the result of determination in step ST9 is that the total load can be processed on all dates, it is determined that the production plan has been completed, and the completed production plan is stored in the database management unit 8. It is registered in the database through (ST12: plan writing means). As a result, the production plan data in the database can be individually referred to for each process or each item from each of the terminals 1 to 6 (: plan data reference means).

Thereafter, the production management terminal 2 delivers a work instruction to each of the terminals 1 to 6 based on the completed production plan draft (ST13: work instruction output means). (Understanding and analysis of production results) In each of the terminals 1 to 6, the work is executed by the operation of the operator based on the distributed work instruction, and as shown in FIG. The production result data shown is transmitted to the database 9 (ST21: production result writing means).

For example, in the plate collecting terminal 5, as shown in FIG. 12, the item DEF undergoes the disassembling of the previous process, and the retouching work is completed by 16:00. Has received a work instruction.

Further, in the plate-collecting terminal 5, the operator's operation allows the production performance data showing the current state of the work to be displayed on the screen as one of the icons "not received", "accepted", "working" and "completed". By making a selection, the production result data of the item DEF in the plate collection is sequentially reported to the database management unit 8.

The database management unit 8 registers this production record data in the database 9. As a result, in each of the terminals 1 to 6, the latest production record can be grasped by inquiring the database 9 for the production record data regarding the department of collecting plates (: record data reference means).

Each time the database management unit 8 receives the production performance data, the database management unit 8 determines whether or not all the processes have been completed for the item corresponding to the production performance data (S).
T22), if all steps are not completed, step S
Returning to T21, as a result of the determination in step ST22, when all the processes are completed, the production result data of the item is sent to the production management terminal 2.

The production control terminal 2 allocates these production record data to the production progress schedule table of the corresponding item, and compares the production record data with the production plan data for each process as shown in FIG. And analyze the consistency of both (ST23: plan / actual inspection means), determine whether or not both data have consistency (ST24: plan / actual inspection means), and compare the production plan data with the production actual data. The process information and the load calculation information are corrected so that the production plan data and the production actual data for the next time and after will be matched with the process indicating that there is no consistency (mismatch) (ST25: reference data correction means).

Here, a modification example in step ST25 will be described. For example, printed matter EF that is issued regularly
Consider the decomposition process of G. The printed matter EFG is already 6
It has been ordered twice and delivered after the work. In the disassembly process,
It is assumed that work result data such as the total work time, the number of decomposition points, and the total number of workers is registered in the database, and each data has the content shown in Table 1 below, for example. Depending on the case, numerical values such as the processing capacity of the scanner per unit time and the resolution ratio may be used (this time, the values shown in Table 1
The type of data is used for the sake of simplicity).

[0040]

[Table 1] For each of these data, regression analysis is performed as shown below.

[0041]

[Table 2]

[0042]

[Table 3]

[0043]

[Equation 1]

[0044]

[Equation 2]

As a result of such regression analysis, the next estimated work time T can be expressed by the following equation (1). T = 48.96x1 ^O.40 x2 ^0.57 (1) where x1 is the number of decomposition points and x2 is the total number of workers.

The parameters (48.96, 0.4) of this equation (1)
0, 0.57) is registered in the database as process information for calculating the load of the disassembling process, and is used for calculating the work load at the time of production planning when the next order is received.

For example, when a seventh order is received for a printed matter EFG and this production planning is performed, parameters for process information are read out from the database and formula (1) is taken out. The total work time (about 273 minutes) can be predicted by substituting the decomposition score (30 points) and the number of workers (2 people) for the seventh order in this equation (1). Then, at the completion of the 7th work of the printed matter EFG,
The work record data for the seventh time is added to the database, and the data having the contents shown in the following table is registered.

[0048]

[Table 4]

Here, the calculation method of the regression analysis, which is the method of calculating the process information of the disassembling work, is applied from the first time of the printed matter EFG to 7 times.
Applied to the work result data up to the second time,
Equation (2) obtained by modifying each parameter of equation (1) is obtained as follows. T = 62.91 x1 ^0.26 x2 ^0.73 (2) Hereafter, similarly to the above, the parameter (62.9
1, 0.26, 0.73) will be registered in the database as revised process information and will be used for the next eight orders.

As a result, the consistency between the production plan data and the production performance data can be improved in the next and subsequent productions, and thus the work efficiency of the entire manufacturing process can be improved.

As described above, according to this embodiment, the database 9 in which the order of the steps, the required number of days, and the load amount per day are stored at least for each item of the printed matter and each step required to create the item. In the production management terminal 2,
When order information including at least the item and the delivery date of the printed matter is input to the database 9, the order and the required number of days for each process are read from the database 9 according to the item, and the order, the required number of days, and the delivery date are also read. Then, production plan data showing the schedule of each process from the order to the delivery is created, and based on the production plan data and the load amount per day in the database 9, the work of each manufacturing department for printing is performed for each date. The load is calculated, and it is judged whether or not the work load is within the allowable range by comparing it with the load allowable amount. As a result of this judgment, when the work load exceeds the load allowable amount, each item on the relevant date is determined. Based on the delivery date of, the priority is added to each item on the date, and based on this priority, the workload on the date is set to the The work of the item having the low priority is changed to another date to correct the production plan data, and the corrected production plan data or the production plan data which is uncorrected and is considered to fall below the load allowable amount is stored in the database 9 Since it is written in, even if there is no expert who is familiar with all processes, it is possible to make a production plan equivalent to the case where there is an expert and improve reliability.

The data can be individually referred to for each process or each item, the production management terminal 2 outputs a work instruction based on the production plan data written in the database 9, and the database management unit 8 responds to the work instruction. do it,
When the production result data including the presence or absence of the work start and the work end is input from each of the terminals 1 to 6, the production result data is written in the database 9, and in each of the terminals 1 to 6, the production result data in the database 9 is referred to. Therefore, the production performance can be accurately grasped with respect to the planned production plan.

Further, according to the present embodiment, when the production management terminal 2 completes all the steps of an item, the production record data in the database 9 for the item and the production plan data for the item are obtained for each step. In comparison with each other, whether the production performance data and the production plan data are in agreement or inconsistency is inspected for each process, and as a result of this inspection, at least for a process in which the production performance data and the production plan data show inconsistency Since any one of the required time, the load amount per day, and the allowable range of the work load in the database 9 is corrected, the production plan for the next time and thereafter so as to match the production performance with the production plan. By modifying
It is possible to maximize the production efficiency while making the production plan consistent with the production result.

In the above embodiment, the case where the process information and the load calculation information are corrected for the process in which the production plan data and the production actual data do not match has been described. Also, the present invention can be implemented in the same manner and the same effect can be obtained even with a configuration in which the entire manufacturing process such as the process route and the work stagnation is analyzed and the process information and the load calculation information are corrected.

In the above embodiment, the case where the multiple regression analysis is used in the disassembling process based on the past production record data has been described, but the present invention is not limited to this, and the cluster analysis is used in the plate collecting process, for example. As described above, the present invention can be carried out in the same manner and the same effect can be obtained even if another analysis method is appropriately used.

Furthermore, in the present embodiment, the case where the total work time, the number of decomposition points, and the total number of workers are converted into natural logarithms and the regression analysis is performed is described, but the present invention is not limited to this. By performing regression analysis without converting the decomposition points and the total number of workers into natural logarithms, the following equations (1a) and (2) corresponding to the equation (1) can be obtained ( Even with the configuration for obtaining the expression 2a), the same effects can be obtained by implementing the present invention in the same manner. T = 5.29x1 + 61.11x2 +11.29 (1a) T = 3.42x1 + 80.56x2 +1.87 (2a) However, as described above, x1 is the number of decomposition points, and x2 is the total number of workers.
