Hoofdstuk 1: Introductie Supply Chain & Operations
Management
Supply Chain Management (SCM)
De Supply Chain = keten van processen die nodig zijn om ruwe materialen naar eindproducten te
transformeren en deze eindproducten tot bij de klant/markt/gebruiker te brengen
Integrale goederenstroom, integrale logistieke keten
Ruwe materialen & componenten eindproduct verpakkingseenheden, distributie en
verkoop
B2B = Business-to-Business, B2C = Business-to-Consumer C2C = Consumer-to-Consumer, G2C
= Government-to-Consumer
Het Supply Chain netwerk bestaat uit:
- Leveranciers (suppliers)
- Productiecentra (manufacturing centers)
- Magazijnen (warehouses): vlakbij de fabriek
• Magazijn: meerdere producten, uitbreidbaar met rekken & mezzanine
• Tank en silo: 1 product tegelijkertijd, niet uitbreidbaar tenzij met dure investering
- Distributiecentra (distribution centers): logistiek en klanten beheren
• Regionaal of lokaal georganiseerd
• Enkel transportknooppunt, of met productiefaciliteiten voor e-fulfilment,
bulk/verpakt, maatwerk (customisation)
- Verkooppunten (point of sales)
• Groothandel (wholesale)
• Detailhandel (retail): vb. supermarkt
• Directe verkoop (direct sales)
Materialen
Grondstoffen (raw materials)
Half afgewerkte producten (intermediate products, semi-finished products, components,
subassemblies): vb. Dingen die rondslingeren in transport
Eindproducten (finished products)
MRO-artikelen: Onderhoudsmateriaal (Maintenance supplies), Reserveonderdelen (Repair supplies,
deze vraag is meestal onvoorspelbaar én dringend, kan het productieproces verstoren),
Gereedschappen (Operating supplies)
Supply chain management
Heeft betrekking op de design, ontwikkeling, optimalisatie en het management van de interne en
externe componenten van de SC (hoe gaan we werken)
Overkoepelt (wereldwijd): aanleveren van materialen, transformatie van het materiaal, distributie
van eindproducten (of diensten) tot aan de klanten
En dit consistent met de algemene objectieven en strategieën van het bedrijf [Spekman, 1998]
- SC Objectieven: Reliability: betrouwbaarheid bij het opleveren, Responsiveness: snelheid
waarmee aan de vraag van klant wordt voldaan, Cost: operationele kost vooraleer producten
te verkopen (Cost Of Goods Sold), Asset efficiency: optimaal gebruik van assets (geld,
resources), Flexibility: wendbaarheid om de SC aan te passen aan andere vraagvolumes
