7 Just in Time (III)

8 Just in Time (IV) Concern level: Hierarchical approach Quartile planning with horizon of 4 month: purchase orders to suppliers Capacity control (long horizon) Assemblage schedule with adequate mix of models (aabbaabbbaa)

9 Material requirements planning (MRP I) demand forecasting from end-products planning the production of parts and materials bill of materials

10 Bill of materials

11 Schedule MRP I bruto behoefte orders onderweg voorzien voorraad verloop netto behoefte geplande ontvangst geplande beschikbaar geplande orderuitgifte
