ECONOMIC ORDER QUANTITY (EOQ) MODEL The economic order quantity (EOQ) is the order quantity that minimizes total holding and ordering costs for the year. Even if all the assumptions don’t hold exactly‚ the EOQ gives us a good indication of whether or not current order quantities are reasonable. What is the EOQ Model? Cost Minimizing “Q” Assumptions: Relatively uniform & known demand rate Fixed item cost Fixed ordering and holding cost Constant lead time (Of course‚ these assumptions don’t always

3.1-06‚ 07 A – A1. Economic Order Quantity Model (EOQ) The Economic Order Quantity Model will allow an organization to determine the optimal volume of inventory to order at a given time. The EOQ model provides the most optimized approach to inventory ordering as it considers‚ demand‚ ordering cost‚ and holding costs; to develop the volume of inventory to be ordered to maintain to minimum annual cost (Render‚ 2012).

for purchase to pass on to the supplier’s customers. EOQ - Economic Order Quantity EOQ is basically an equation used to determine inventory stock. It figures the ideal quantity to order that a particular supplier should maintain in warehouse‚ determined by a consistent cost for production‚ demand‚ etc. It basically figures out the best numbers for a supplier to produce in the chain of supply and demand in order to make a profit. Its purpose is to help maintain a consistent inventory
