Inventory models use different variations of the economic order quantity (EOQ) model in order to determine proper order or production quantities. Besides the standard EOQ model, the economic production quantity (EPQ) model is included. For both the EOQ and EPQ model, models that allow shortages are included. Finally, quantity discounts for the EOQ model are allowed.
A second type of model is ABC analysis.
The last two models are used for computing reorder points for Normal distributions and discrete distributions.
