Advantages of Inventory
- customer satisfaction because of quick response to demand
(- economies of scale, I don’t know why though) - smaller influence of rising price levels
Disadvantages of inventory
- it may bring high inventory costs
- risk of aging of products (obsolescence)
- loss of products because of theft or damage
Types of inventory
1- Raw Materials
2- Work-in-progress
3- Maintenance, repair, operation (MRO) = goods that have to be stored to keep the system going
4- Finished goods
Customer Order Decoupling Point (CODP)
“point in the supply chain, from which the product flows to the customer, when the customer demands it “
- decision made at a strategic level
- also called push/pull boundary
Downward movement
product flows towards the customer
Upward movement
product flows back to the factory (due to a defect)
Push Strategy
area to the left of the CODP in the supply chain
Pull Strategy
area to the right of the CODP in the supply chain
Advantages &; Disadvantages of CODP close to CONSUMER
Advantages
- quick delivery to consumer
- lower price to consumer, because of economies of scale
Disadvantages
- high risk of inventory
- products are usually standardized, the customer has little to say about the final product
Advantages &; Disadvantages of CODP close to PRODUCER
Advantages
- customer has a say in the final product
- production occurs with minimal costs of inventory
Disadvantages
- it may take long for the product to be finished
- market can change in the meanwhile, making the product unnecessary
Process Strategy &; the CODP
- make to stock (product focus) –> close to consumer
- Assemble to order (repetitive focus): semi-finished products. –> somewhere in the middle of the supply chain
- make to order (process focus): e.g. raw materials. –> far away from the consumers
- engineer to order: custom made products –> very close to the producer
POQ annual usage
is the demand
cycle counting
random counting of a part of the inventory and base your estimations for the rest of the inventory on this data.
ABC analysis
Is a way of applying the cycle count.
You divide the inventory in 3 categories according to the euro-volume worth (TR product yields)
Fixed order quantity models
EOQ, POQ, QOD
