Balance Problems

It studies the balance problems of cycle time of a flywheel production line in this paper. Based on the working time measured using lean manufacturing (LP) methods, the bottleneck processes of production line are found by simulating with software Witness, which is improved by using production cycle balancing method. Comparing the relevant parameters before and after the production line balance,the improvement results of production line are significant and the production efficiency can be improved.

New Research

Existing scheduling systems cannot respond quickly and efficiently to the appearance of uncertain variable interference factors in the scheduling process. The efficiency of the enterprise is hence seriously affected by these factors. The concept of the digital twin provides new research directions for scheduling systems. In order to improve the overall performance of the production scheduling system in a frame shop, virtual-real fusion technology utilizing the digital twin is first introduced to integrate the information and logistics flows in the scheduling process as part of the manufacturing execution system-based production scheduling mechanism. The balance optimization of the mixed-flow production line is then carried out, and the mixed-flow production line balance and sequencing models are established. A scheduling system for the frame shop combining various system functions is finally designed based on the sequencing model and production status. The scheduling system comprehensively considers the two uncertain factors of materials and orders to generate scheduling information through an intelligent scheduling mode while realizing real-time synergy between the information and logistics flows. The system has achieved excellent implementation results in the frame shop and provides a reference for the application of digital twins in production workshops.
