Heijunka (Level Scheduling)
Heijunka (Level Scheduling) & Production Smoothing
Primary Goal
Balancing production volume and variety over time.
Eliminating
Mura (Unevenness) and the Bullwhip Effect.
Critical Tool
Heijunka Box (Scheduling and Leveling Board).
Leveling & Flow Strategies
Transitioning from large batches to mixed-model production planning,
Preventing demand fluctuations from disrupting the shop floor through "smoothing,"
Integrating SMED (Single Minute Exchange of Die) to support frequent changeovers,
Stabilizing capacity by optimizing labor and machine utilization rates,
Ensuring predictable and sustainable inventory levels throughout the supply chain.
