Method and system for realizing balanced production of whole-automobile general assembly shop

Abstract

The invention discloses a method and a system for realizing the balanced production of a whole-automobile general assembly shop. The method comprises: (1) a preprocessing step, (2) a classification monitoring and acquisition step, (3) an alarming step and (4) a disturbance factor processing step. The system comprises a shop information interactive terminal (1), a station information acquisition unit (2), an information display terminal (3) and a disturbance processing unit (4). The method and the system are suitable for the automobile general assembly shop using mixed-line production, and can fast and effectively process various disturbance factors during the production of the automobile general assembly shop, improve the capacity of fast recovering the balanced production of a production system of the automobile general assembly shop after a plurality of disturbance factors occur, and find out weak links during the production of the automobile general assembly shop by statistical analysis on the occurring disturbance factors of the automobile general assembly shop and the methods for processing the disturbance factors to provide bases for the continuous improvement of the automobile general assembly shop.

Description

technical field [0001] The invention relates to a method and system for realizing balanced production in an automobile assembly workshop. technical background [0002] The automobile manufacturing industry occupies a very prominent proportion in the modern manufacturing industry. In the face of increasingly diverse customer needs, automobile manufacturing enterprises should actively respond. The assembly workshop is located at the end of the four major processes of stamping, welding, painting, and assembly in vehicle production, and directly faces market customer orders. For general automobile manufacturers, most of the assembly parts required for the body of the assembly workshop come from the supply of their upstream workshops. Most of them use the method of pulling the production of painting, welding and stamping workshops based on the plan of the assembly workshop. The material demand fluctuations from the assembly workshop are transmitted to the upstream workshop layer...

AI Technical Summary

Problems solved by technology

[0003] The production of the assembly workshop is complicated, and various uncertain factors and disturbance factors occur from time to time, such as equipment failure, material loss at the production line, abnormal quality of assembly parts, urgent order insertion and other dominant disturbances, as well as unbalanced consumption of line-side materials and uneven load of production line stations. Equal implicit disturbances make it more difficult to balance production in the assembly shop

Factors such as production line shutdown, inventory fluctuation, and waiting for processing occur from time to time, which waste a lot of time and become one of the important factors affecting the timely delivery of automobile companies
