<p>A method (116) of calculating an order quantity for a product to maintain an inventory level at a future time includes determining an inventory sum and an inventory coefficient over a previous time interval (step 118), determining a demand sum and a demand coefficient for the product over the previous time interval (step 120), determining an orders sum and an order coefficient for the product over the previous time interval (step 122) multiplying the inventory sum and the inventory coefficient to produce an inventory level, the demand sum and the demand coefficient to produce a demand level, and the orders sum and the order coefficient to produce an order level (step 124), and summing the inventory level, the demand level, and the order level to obtain the order quantity (step 126).</p> |
