AI Technical Summary

Technical Problem

Existing MES systems cannot effectively predict downstream load changes in multi-station production, causing bottleneck stations on the production line to shift in real time with changes in process parameters, equipment status, or order switching. This can easily lead to the omission of hidden bottlenecks, resulting in work-in-process accumulation or quality defects, causing production line imbalance, reduced equipment utilization, and product delivery delays.

Method used

By acquiring the processing records of products at each workstation, calculating the basic time consumption and infection intensity values, marking the infection source workstation and sensitive workstation, monitoring the amount of infection deviation and the speed of spread in real time, and classifying and determining the rhythm adjustment signal or blocking signal, the precise coordination of the production rhythm can be achieved.

Benefits of technology

It improves the effectiveness and accuracy of production cycle coordination, can target key workstations, prevent the spread of anomalies, reduce production line downtime, and improve equipment utilization and on-time product delivery.

Abstract

This invention discloses a multi-workstation MES production cycle coordination control method, relating to the field of intelligent manufacturing technology. The method includes step one: obtaining the processing time of multiple processing records of the product at different workstations within the most recent 72 hours, and calculating the basic processing time of the product at each workstation; by calculating the expected infection time increment and spread rate, the infection path is divided into two categories: prevention and adjustment level and emergency blocking level based on the infection deviation and spread rate. Differentiated cycle control strategies are adopted for different levels of abnormal situations, ensuring that the production cycle adjustment is neither overly conservative and affects production capacity, nor overly conservative and decisively blocks the spread when the abnormality is severe, thereby improving the resistance to cycle anomalies and the overall operational stability.
