  1. Logistieke concepten College 5 (hoofdstuk 11 en 14 Ronald H. Ballou)

  2. Supply scheduling decisions • Purchasing scheduling decisions • Network Planning Process

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

  4. Just in Time (I) Japanese production philosophy: • 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

  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 • Quartile planning with horizon of 4 month: purchase orders to suppliers • Capacity control (long horizon) • Assemblage schedule with adequate mix of models (aabbaabbbaa)

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

  9. Bill of materials

  10. Schedule MRP I • bruto behoefte • orders onderweg • voorzien voorraad verloop • netto behoefte • geplande ontvangst • geplande beschikbaar • geplande orderuitgifte

  11. Voorbeeld MRP I

  12. Problems MRP I • demand uncertainty • lead time uncertainty • safety stock • Manufacturing Resources Planning (MRP II) • koppelt planning en besturing • koppelt afdelingen

  13. Position MRP I/II

  14. Supply Chain Management • Optimise the integral chain • Integration of information • Value Adding Logistics: • functies die thuishoren in material management (assemblage, verpakken) verplaatsen naar de distributie keten • Information technology

  18. Data for network planning • products in the product line • locations • materiaal, productie, opslag en services. • costs • customer service level • capacity

  19. Sources Business planning documents Reports Logistic research Published information Encoding Product coding Geocoding Data sources and encoding

  20. From data to information • Product grouping • Sales aggregation • geografische clusters • relatie cluster en verkoop concentratie

  21. Design the network • Chart, compass and ruler techniques • Simulation models • Heuristic models • Optimization models • regel van Camp

  22. Opdracht 3: besturing • Casus: “de internet super” • Geef in een presentatie (per groep) een advies over een besturingssysteem
