Consider a single warehouse facing constant demand for a single item. The warehouse orders from the supplier, who is assumed to have an unlimited quantity of the product. The EOQ model assume the following scenario: Annual demand D is deterministic and occurs at a constant rate-constant demand rate: i.e., the same number of units is taken from inventory each period of time, such as 5 units per day, 25 units per week, 100 units per month and so on. Order quantity are fixed at Q units per order. Du (UNB) SCM 14 / 83 Economic Order Quantity (EOQ): Model description II A fixed ordering cost c o per order, not depending on the quantity ordered.

Interest in the problems of optimal stock management at a scientific level goes back to the start of the 20th century. The most important impulse, however, came after the 2nd World War when scientists of the caliber of Jacob, Marschak, Kenneth Arrow, Samuel Karlin among others looked into the problem of optimal stocking under stochastic demand. It was characteristic of this discipline, that methods of solving problems of this type were developed first before the necessary commercial electronic data processing for their ready application were available.

The definition of inventory and various types of inventories – raw materials, finished goods, in-process inventory, MRO inventory , etc. – are outlined. The need to keep inventory and the functions of inventory as a decoupling agent to enable various subsystems in a supply chain to be decoupled are described. The inventory-related cost parameters are listed along with methods of estimating these. Other situational parameters like demand and lead times also need to be estimated. Before an inventory model is employed for optimal operation of the inventory system, an appropriate inventory policy has to be selected. Three types of inventory policies are described, and their relative strengths and weaknesses are discussed. A taxonomy of inventory models is presented to give an overview of a plethora of inventory models available in inventory management literature. However, the right choice of the inventory model is crucial for the success of inventory management.
