Abstract

PURPOSE:To perform production matching in a delivery date and to eliminate deviation in a load on facility by a worker by providing a work instruction priority decision means to decide priority by utilizing an order deliver date margin rate and a work margin rate. CONSTITUTION:A manufacturing schedule registration means 1 registers input information having plural working procedures for one order on an order managing data base 11, and allocates and registers registered data on each process, and generates a process managing data base 12. Also, the work instruction priority decision means 2 calculates the order delivery date margin rate being conscious of the delivery date of an order at every work at every working process and the work margin rate being conscious of the margin of the work, and outputs a value (order delivery date margin rate x work margin rate) in sequence of low order to a display device 13, and attaches the priority on the instruction of the work. Thereby, it is possible to surely perform the production matching in the delivery date, and to make a work load into leveling.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a process control device, and is applicable to general manufacturers who carry out manufacturing by differentiating processes in the process of receiving orders, manufacturing and delivering products. The present invention relates to a process control device for.

[Conventional technology]

In conventional manufacturing companies, management in the process of manufacturing products from receiving an order was performed separately: management at the delivery date level and management at the process level, that is, the field work level. In particular, when manufacturing one-order products, when each process is divided into on-site work, the prioritization of each process is left to the know-how of skilled workers such as foremen, group leaders, and supervisors. Met. Recognizing that they would be manufacturing parts that overlapped with other products, they created lines for each product.

[Problem to be solved by the invention]

Conventionally, when manufacturing products, the delivery date of the product and the manufacturing status flowing through the process are not managed together, so although the staff department may be able to prioritize the product, from the perspective of the shop floor, it is difficult to manage each product separately. There is a lot of work to be done on products, and it is difficult to know where to start, and the management is left to the know-how of skilled workers, which has the disadvantage of not being able to make accurate decisions. The disadvantage is that the load on the equipment is uneven.

In addition, companies that have separate lines for each product may not be able to produce on time, or may produce the same parts on different lines, resulting in wasted man-hours and materials.

Furthermore, as we enter the era of high-mix, low-volume production, the division of labor and product types are increasing, which has the disadvantage of spurring an increase in management man-hours. Receiving parts and semi-finished products between companies has the disadvantage that unnecessary loss time occurs during delivery, and it is difficult to control the progress of manufacturing.

[Means for Solving the Problems] The process control device of the present invention calculates the order delivery margin rate set by the remaining work time of a single manufacturing point, which is an order, the time until the next work, and the remaining time of own work. Work instruction prioritization is a method for prioritizing and selecting work instructions using the work margin rate set in A performance collection means for collecting performance based on the work instruction sheet, and an order progress inquiry means for inquiring about the work progress of the order based on the collected data.

〔Example〕

FIG. 1 is a block diagram showing an embodiment of the process control device of the present invention.

As shown in FIG. 1, the process control device of this embodiment creates an order management database 11 by inputting work procedure information for each order, and uses that information to create a process control database 12.
This is a device that creates a process management database 12, issues work instructions, and collects results based on this process management database 12.

FIG. 2 is an explanatory diagram showing an example of the creation status of an order management database and a process management database.

A first manufacturing plan registration means 1 for registering a manufacturing plan in a process control database inputs input information having a plurality of work procedures for one order into the order management database of FIG. 1, as shown in FIG. Register on 11. Note that the registered media include magnetic disks, magnetic tapes, displays, cards, etc., and the number of orders does not matter. Next, the data registered in the order management database 11 is allocated and registered to each process as shown in FIG. However, when registering, one step at a time is performed, first the first task is registered, and when the first task is instructed, the second task is registered.

In addition, method 2 for prioritizing work instructions calculates the order delivery margin rate with consideration to the order delivery date and the work margin rate with consideration to the work margin for each individual operation in each work process, and calculates the order delivery margin rate *The work margin ratios are output to the display device 13 in descending order of their value to give priority when giving work instructions. The calculation formula for each is shown below.

FIG. 3 is a time chart showing an example of a manufacturing plan.

Remaining work time for the order In the case of Figure 3, the order delivery margin rate for order A = 77
, □1-, and the smaller the value, the higher the possibility that the delivery date will not be met. In addition, if the value is less than 1, it means that it is impossible to secure the delivery date in the current state, so it is necessary to change the plan, such as having the delivery date shifted, or to increase the number of people working during the planning process. You will need to take it.

In the case of the remaining work time of the work shown in Figure 3, the work margin rate of order A = Y,
The smaller the value, the higher the possibility that the next task will be delayed. Furthermore, if the value becomes 1 or less, the next work will be started with a delay if the current state remains as it is. In the case of Fig. 3, the priority order of the work instructions is A order work 1. □×÷, B order work 1: The smaller the value of city×÷, the higher the priority.

Furthermore, if the order delivery margin rate is 1 or less, and if the work margin rate is 1 or less, the risk level is output to the display device.

Next, the work instruction sheet issuing means 3 stores the latest instruction number for each process in the instruction sheet number numbering file, and updates the numbering number by adding 1 every time one instruction is issued. Then, necessary information is extracted from the process management database 12 and a work instruction form 14 is issued. Then, the work of the next procedure on the order management database 11 is registered in the process management database 12.

On the other hand, the performance collection means 4 is started and stopped by inputting the work instruction number from the performance collection terminal as a key.

Processing is performed based on achievements such as completion. That is, the work status of the process work record and the work status of the order work record are updated with the input status, and the work is deleted from the process management database 12 when the completion record is input. Then, at the time of completion input, if the work is the final work, the order is deleted from the order management database 11.

Further, the order progress inquiry means 5 searches the order management database 11 using the order number as a key, and by checking the status of each work procedure, searches for the progress status of the order and displays it on the display device 13.

〔Effect of the invention〕

As explained above, the process control device of the present invention handles the management of each order and the management of each work process in real time from two sides, making production on time more reliable than before and reducing workload. This has the effect of leveling out the production process, smoothing the linkage of operations between processes, and monitoring the manufacturing progress, making it possible to fully meet the diversifying needs of high-mix, low-volume production.
