3. SUPPLY SCHEDULING Meeting demand:
supply just when needed production (MRP)
inventory replenishment (JIT)

4. Just in Time (I) Japanese production philosophy: Inventory reduction
juiste producten, juiste tijdstip, juiste plaats, juiste kwaliteit, juiste hoeveelheid
Inventory reduction
“voorraad is smeermiddel van knelpunten”
Production: small size and zero defects
Relation with supplier
omstel tijden verkorten om kleine series te kunnen maken.

5. Just in Time (II) KAN card: produce a standard quantity
BAN card: bring a standard quantity
KANBAN control on department level
Demand approach, i.s.o. hierarchical approach

6. Just in Time (III)

7. Just in Time (IV) Concern level: Hierarchical approach
