Method and system for management and control of articles being processed

Abstract

The present invention relates to a method and system for management and control of articles being processed in an automatic production manufacture environment. The method comprises: receiving a shift-out request of articles being processed from a first process unit of a first working procedure; determining whether a second working procedure corresponding to the shift-out request is a managed and controlled working procedure or not; in the condition that the second working procedure is not the managed and controlled working procedure, responding to the shift-out request to shift out the articles being processed, and in the condition that the second working procedure is the managed and controlled working procedure, determining the current number of the articles being processed used in the second working procedure exceeds a management and control threshold or not; and in the condition that the current number of the articles being processed used in the second working procedure exceeds a management and control threshold, stopping responding to the shift-out request.

Description

technical field [0001] The present invention relates to the field of automatic control, and more specifically, the present invention relates to a work-in-progress control method and a work-in-process control system in an automated manufacturing environment. Background technique [0002] In an automated manufacturing environment, the products being processed in each production process and the semi-finished products ready for further processing are called work-in-process (WIP). In the actual production process, due to the differences in stability and marriage rate between the process equipment of each production process, the production capacity between the preceding and following processes is unbalanced, which leads to the in-process production in its process equipment and related storage equipment (such as , the accumulation in the stocker). The accumulation of a large number of WIP will increase the difficulty of logistics transportation, resulting in uneven distribution of...

Problems solved by technology

In the actual production process, due to the differences in stability and marriage rate between the process equipment of each production process, the production capacity between the preceding and following processes is unbalanced, which leads to the in-process production in its process equipment and related storage equipment (such as , the accumulation in the stocker)

The accumulation of a large number of WIP will increase the difficulty of logistics transportation, resulting in uneven distribution of WIP, and even the current stocker where the process equipment is currently located has no place to store WIP, which will greatly reduce the handling efficiency and affect the production capacity of the factory.

In addition, the accumulation of a large amount of work in progress is also a great waste of production. Too much work in progress stored in the factory will lead to a large reduction in the liquidity of the producer, which will have a certain impact on the operation of the factory and the sensitivity of the market response. influences
