The difference(s) between the basic EOQ model and the pro-duction order quantity model is (are) that:
a) the production order quantity model does not require theassumption of known, constant demand.b) the EOQ model does not require the assumption ofnegligible lead time.c) the production order quantity model does not require theassumption of instantaneous delivery.d) all of the above.
A manufacturer of exercise equipment purchases the pulley section of the equipment from a supplier who lists these prices:
Less than 1000 $5.00 each
1000 to 3999 $4.95 each
4000 to 5999 $4.90 each
6000 or more $4.85 each
Ordering costs are $50, annual carrying costs per unit are 40 percent of purchase cost, and annual usage is 4900 pulleys. Determine the order quantity that will minimize total cost.
