Problems solved by technology

In addition, the producer has excess inventory or causes an increase in inventory, so the producer wants to have the appropriate amount of inventory at the appropriate timing
[0004] It is necessary to derive appropriate inventory according to demand fluctuations, yield deviations, equipment failures, and supplier delivery delays, but these values ​​are not fixed and will Changes often

Embodiment 1

[0047] Below, use Figure 1 to Figure 18 Examples of the present invention will be described.

[0048] figure 1 It is an explanatory diagram of the production management system according to the first embodiment of the present invention.

[0049]The production management system includes a manufacturing department terminal 1 , a material department terminal 2 , and a production management department server (management computer) 3 . The manufacturing department terminal 1 , the material department terminal 2 , and the production management department server 3 are connected via a network 7 . In addition, the manufacturing department terminal 1 and the material department terminal 2 are collectively referred to as terminals.

[0050] Manufacturing sector terminal 1 is the pair contained in the figure 2 A terminal that manages the actual performance information of the manufacturing process in the production process described in . The manufacturing department terminal 1 stores ...

Embodiment 2

[0182] Next, use Figure 19 Example 2 of the present invention will be described.

[0183] In this embodiment, instead of embodiment 1 Figure 17 The shown inventory detailed screen 1700 displays the preceding and following process actual performance detailed screens 1900 . Figure 19 It is an explanatory diagram of the detail screen 1900 of actual results of preceding and following processes in Example 2 of the present invention.

[0184] exist Figure 17 In the above, when an item is selected on the appropriate inventory detail screen 1700, the previous actual performance detailed screen 1710 is displayed, which displays the daily performance of the manufacturing process preceding the selected process. However, in this embodiment, the display The previous and subsequent process actual performance detailed screen 1900 includes actual performance information of a manufacturing process immediately preceding the selected process and actual performance information of a process...

Embodiment 3

[0200] use Figure 20 and Figure 21 Embodiment 3 of the present invention will be described.

[0201] In this embodiment, only the number of current requests is displayed in the shipping destination performance display area 1931 of Embodiment 2, and the life cycle of the product is judged based on the number of current requests, and a suggestion to correct the appropriate inventory reference value information 42 according to the life cycle is displayed.

[0202] Figure 20 It is an explanatory diagram of the shipping destination performance display area 1931 according to the third embodiment of the present invention. Figure 21 It is an explanatory diagram of the transition of the number of shipping requests in Example 3 of the present invention.

[0203] Such as Figure 21 As shown, according to the migration of the number of products required to be shipped from the shipping destination, that is, the number of shipping requests, the life cycle of the product is divided i...

Abstract

A production management system for managing at least one process for producing a product, has a terminal and a management computer. The management computer obtains actual performance information from the terminal, and calculates a discrepancy of the actual performance value of the process from the reference value. In a case where the calculated discrepancy is outside a threshold, the management computer displays an alert display screen. In a case where one of the processes is selected on the alert display screen, the management computer displays a details displaying screen that includes, for each product, an actual performance value in the selected process.

Description

technical field [0001] The present invention relates to a production management system that manages processes for producing products. Background technique [0002] In the manufacturing industry, it is necessary to consider various factors such as changes in demand for products, yields in production processes, changes in production cycles, and changes in parts supply cycles. Cycle time refers to the time from starting a process to finishing it. [0003] Generally, producers can cope with these changes by having inventories of components, intermediate products, and finished products. For example, when it is assumed that the yield rate is low in a specific process, the manufacturer can prevent shipment delays by increasing the inventory of products produced in the specific process. In addition, the yield rate refers to the ratio of good products that are not non-defective products to all products. In addition, since the producer has excess inventory or causes an increase in ...
