• Where should the order be produced?
• Do we have materials for the order?
• Do we have adequate capacity?
• Who should produce the order?
• What will be the delivery time?
• What will be the costprice?
• Where must the order be delivered?

Logistic management principlesLogistic management principles
Fordisme◦ Planning af prognoses and production for stock
Lean◦ Avoid waste by reducing all not value adding activities◦ Planning starts by the customers needs to avoid stocks
Agility◦ Is based upon extreme customer orientation.◦ Works with higher prices and higher profits margins
because it is more important to supply flexible and fast on differentiation rather than cheap

FordismeFordisme
Characterised by:
◦ Production to stock◦ Specialised machines◦ Focus on productivity◦ Focus on standardisation◦ High degree of work specialisation◦ High production volumens

LeanLean
The strategy in lean is to avoid waste by all non-value adding activities.
The planning of production starts by the customers actually need to avoid stocks.
It means better customer service and less costs.

LeanLean
7 types of waste:
1. Overproduction2. Waiting time3. Unnessary tranport4. Process waste5. Unnessasary stock6. Unnessasary operations7. Lack in quality

LeanLean
Lean is known by:
◦ Production to actual customer need◦ Focus on quality◦ Focus on flexsibility◦ Focus on standardisation◦ Involvement of employees◦ High production volumens

Push vs Pull driven supply chainsPush vs Pull driven supply chains
PushIf products are taken from stock it means that they have been produced or bought in advance based upon expected sales.
PullIf production or purchase are not made before the customer orders them the supply chain is pull driven

De-coupling point
Raw materials End customer
De-coupling point separates push-driven activities in the supply chain from activities in the supply chain that are pull-driven

Manufacturing strategies
1. Engeneering to order (ETO)
2. Sourcing to order (STO)
3. Make to order (MTO)
4. Assemble to order (ATO)
5. Packaging to order (PTO)
6. Labeling to order (LTO)
7. Deliver to order (DTO)

Postponement
the point where the differentiation of the product take place
spreading the risk of inventories in the distribution channel
Driving forces for postponement: increased difficulties with forecasting demands increased demand after customized products increased manufacturing costs incresed competition increased distribution costs increased research and development costs

Push MRPPush MRP
MRP contains the following head components:
Overall planningDetailed planning of materialsDetailed planning of capacitySurvilance of deliveries
MRP is a concept based upon forecasts

Management concept JITManagement concept JIT
Is a concept under LEAN which based upon the customer need deliver products:
in the right time in the right amount at the right place
Production starts first when the order is received in the sales department.
