There are four primary types of inventory management:
1) Order Point: This type of inventory management determines when to order more inventory based on a pre-determined minimum stock level. This system ensures that you never run out of inventory, but it can result in higher carrying costs due to excess inventory levels.
2) economic order quantity (EOQ): This type of inventory management determines the optimal order quantity to minimize the total cost of inventory (i.e. the cost of the goods themselves, storage costs, and ordering costs).
3) just-in-time (JIT): This type of inventory management is designed to minimize inventory levels by only ordering goods when they are needed. This can help to reduce carrying costs, but it can also lead to stock outs if there are any delays in the supply chain.
4) Vendor-managed inventory (VMI): This type of inventory management is where the supplier of the goods is responsible for managing the inventory levels. This can help to reduce the burden on the company, but it can also lead to higher costs if the supplier is not managed effectively.
