Production managment method and method for manufacturing electronic equipment

Abstract

The present invention provides a production management method and a manufacturing method of electronic equipment, which relate to an appropriate production management method used in the manufacture of electronic equipment such as liquid crystal display devices, and aim to provide production management capable of setting an achievable target number of processes method. In the production management method of a production line composed of multiple processes A~D, the tentative target processing number NR_D of the main process D is preset. When the actual processable WIP SR is greater than the tentative target processing number NR_D, the The provisional target number of processes NR_D is set as the target number of processes SR_D, and when the processable number of WIPs SR is smaller than the tentative target number of processes NR_D, the processable number of WIPs SR is set as the target number of processes SR_D.

Description

technical field [0001] The invention relates to a production management method, in particular to a production management method suitable for use in the manufacture of electronic equipment such as liquid crystal display devices. Background technique [0002] The applicant of the present application proposed a method of production management in a process group in which capabilities can be transferred to each other generally by sharing equipment in their Japanese Patent Application (JP-A-2001-273023 (hereinafter referred to as Document 1)). In this production management method, first, the ratio of the number of required product processing to the product processing capacity of each process in these process groups, that is, the load factor is obtained, and used as the load factor for each process during the entire operation period that is the object of the mid-schedule production plan. The ratio of the scheduled cumulative production to the cumulative capacity of each process. T...

However, there is no such scheduling method that maximizes the handling of bottleneck engineering

[0007] In addition, in a production line in which serial number series items that are batched and discretely input and serial number series items that are input continuously are mixed, there arises the following problem: The calculated equalization target processing number does not fit the processing target for the serial number series of discrete inputs
