Economic Order Quantity

Economic Order Quantity EOQ,Economic Lot Size

More order quantity and less order frequency bring less order cost, but the inventory and inventory carrying cost increase. In order to reduce the inventory carrying cost, in contrast, less order quantity and more order frequency bring more order cost. Economic Order Quantity (EOQ for short) refers to the best order quantity to make the total cost minimum by considering the balance between ordering cost and inventory carrying cost, which are contradictory. In Economic Order Quantity as a method for lot sizing by MRP, the Economic Order Quantity for each item is calculated in advance and entered to the item as the EOQ value. In MRP, lot sizing is performed according to the EOQ value in the same method as Fixed Order Quantity. For how to calculate an EOQ value and how to size lots, see Economic Lot Size and Fixed Order Quantity, respectively.
