Q:

How is Line Balancing Efficiency measured?

Line Balance Efficiency (η) is the ratio of total work content to the total capacity allocated across all workstations: η = (Total Work Content / (Number of Workstations × Takt Time)) × 100% The remainder represents Balance Delay (idle waiting time).

Workstation Balancing & Flow Synchronization

Balancing manual assembly lines eliminates station bottlenecks, stabilizes one-piece flow, and minimizes unneeded operator overtime.
