Course Overview
In a multi-product environment, demand leveling and HEIJUNKA (a Japanese term for “make flat and level”) absorb fluctuations in demand while keeping inventory buffer levels low and even by dynamically managing production batch sizes, variety, timing and sequencing.

Demand leveling breaks down the total volume of orders for a given planning period (e.g. two months, one month) into scheduling intervals (weekly, daily).

HEIJUNKA calculation then defines a repetitive production sequence for that scheduling interval, which dictates the model mix scheduled on a given line.

That schedule is put into operation through the production and distribution of KANBAN cards or signals for the mix of products.

Heijunka / Production Leveling play an important role in process / Product development and process / Product to improve performance and the benefits from the course is:
 ·More effective use of manpower
 · Lower investment as many models on the
       same line
 ·Requires less machines & equipment
 ·Reduce inventory
 ·Distributes work evenly among all steps in the
       production sequence
