Production levelling (Heijunka)

In contrast to the classic approaches of production planning, the priority of Heijunka is not combining production lots but achieving a constant production rhythm. This is obtained by a clever combination and the “bit-by-bit” placement of production orders. This helps to avoid a too high or too low efficiency of a production system.

Heijunka must be applied very carefully in combination with other methods because there is a conflict of goals with just-in-time production.

Benefits resulting from Heijunka:

• Increased quantity produced
• Improved quality
• Improved production flow and thus improved processing time
