ECONOMIC ORDER QUANTITY • A strategic factor in inventory control is computing the optimum size of a normal purchase order. It is the quantity of inventory which can be reasonably ordered at a time and purchased economically.It is also known as standard order quantity or economic lot size. • E.O.Q. = √2 R.Cp Ch

• Q- Two materials x and y are used as follows Normal Usage Minimum Usage Maximum Usage Re-order period

50 units per week 25 units per week

75 units per week X : 4 To 6 week Y : 2 To 4 week Re-order quantity X : 300 units Y : 500 units calculate 1) re-order level ,min. level , max. level, average inventory level.

Q- Calculate the E.O.Q.from the following information: consumption of material per annum 10000 kg order placing cost per order Rs 50 cost per Kg of raw material Rs 2 storage cost 8% on avg.inventory
