Purpose: One challenge in inventory control models is to know the stock available at the beginning of the cycle to … satisfy future demands, i.e. to know the on-hand stock levels at order delivery. For inventory managers, this knowledge is … necessary to both determine service levels and establish the control parameters of the inventory policy. However, the …
