In inventory management, economic order quantity (eoq) is the order quantity that minimizes the total holding costs and ordering costsit is one of the oldest classical production scheduling models the model was developed by ford w harris in 1913, but r h wilson, a consultant who applied it extensively, and k andler are given credit for their in-depth analysis. 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.
Burgoon uses an economic order quantity model and has determined an optimal order size of 500 units annual demand is 10,000 units, ordering costs are $50 per order, and holding costs are $4 per unit. There is a large number of possibilities between an order size of 1 and 100,000 it is obvious that each time an order is placed some purchasing costs are incurred, and that as the number of orders placed increases, the total cost of purchasing. By joannes vermorel, january 2012 eoq is the purchase order quantity for replenishment that minimizes total inventory costs the purchase order is triggered when the inventory level hits the reorder pointthe eoq is calculated in order to minimize a combination of costs such as the purchase cost (which may include volume discounts), the inventory holding cost, the ordering cost, etc. How to make eoq relevant again (jit) and lean have led many to question the continued relevance of economic order quantity (eoq), whose function is to identify the optimum order with the lowest cost parameter remember, eoq balances supplier/vendor order size, order frequency, the timing of orders and storage and handling to minimize. Long run costs, using the standard economic definition, are all variable there are no fixed costs however, in the short run, the ability to vary costs in response to changing output levels and mixes differs among the various modes of transportation the presence of economies of scale means that as the size of the transport firm gets.
Aggregating multiple products in a single order transportation is a significant contributor to the fixed cost per order can possibly combine shipments of different products from the same supplier – – – – same overall fixed cost shared over more than one product effective fixed cost is reduced for each product lot size for each product.

Given the above we can develop the basic economic order quantity it will tell us how much to order with a goal of minimizing the total annual inventory cost (taic all over 200 units in a single order - $480/unit transportation costs - $6/cwt (cwt=100 lbs) for a full truckload of 50,000 lbs (100 buckets). The ordering cost, ie, the cost of placing an order plus the cost of the bicycles be- ing purchased, has two components: the administrative cost involved in placing an or- der is estimated as $200, and the actual cost of each bicycle is $35 for this wholesaler.
