A Novel Approach to Dynamic Line Balance Control and Scheduling with a Digital Twin Production

We have created a line balancing algorithm that uses queueing theory to calculate ideal WIP (Wafer In Process) targets by product and step taking into account the current factory bottlenecks and status, which realize higher equipment utilization, more outs, better WIP bubble/bottleneck management, and reduction of opportunity loss. In this paper, the system architecture and deployment result are described.
