Economic Order Quantity is the level of inventory that minimizes the total inventory holding costs and ordering costs. It is one of the oldest classical production scheduling models. Economic order quantity refers to that number (quantity) ordered in a single purchase so that the accumulated costs of ordering and carrying costs are at the minimum level. In other words, the quantity that is ordered at one time should be so, which will minimize the total of. Cost of placing orders and receiving the goods, and Cost of storing the goods as well as interest on the capital invested.

economic order quantity (EOQ)

The economic order quantity can be determined by the following simple formula:



economic order quantity (EOQ) formula

EOQ = Economic Order Quantity,

RU = Annual Required Units,

OC    = Ordering Cost for one Unit

UC = Inventory Unit Cost,

CC = Carrying Cost as %age of Unit Cost

Example 3:  

Midwest Precision Control Corporation is trying to decide between two alternate Order Plans for its inventory of a certain item. Irrespective of the plan to be followed, demand for the item is expected to be 1,000 units annually. Under Plan 1st, Midwest would use a teletype for ordering; order costs would be Rs. 40 per order. Inventory holding costs (carrying cost) would be Rs. 100 per unit per annum. Under Plan 2nd order costs would be Rs. 30 per order. And holding costs would 20% and unit Cost is Rs. 480. Find out EOQ and Total Inventory Cost than decide which Plan would result in the lowest total inventory cost?
