f. comparing the Dynamic Order Point to the on-hand quantity;
g. identifying a particular consumer at said work station;
h. inputting, at said workstation, item identification information for each item issued to the particular consumer as issued-item data;
i. communicating the issued-item data from said work station to said central computer;
j. decrementing, in said central computer, the issued item from the on-hand quantity;
k. comparing the Dynamic Order Point to the on-hand quantity;
l. adding, by said central computer, responsive to the Dynamic Order Point being at least equal to the on-hand quantity, the maximum days inventory value and the lead time days value to generate a second sum;
m. multiplying, by said central computer, the second sum and the average daily usage value to generate a product;
n. adding, by said central computer, the on-hand quantity and the open order quantity to generate a third sum;
o. subtracting, by said central computer, the third sum from the product to generate a quantity representing a Dynamic Order Quantity for the item;
p. generating a replenishment order for purchasing the Dynamic Order Quantity of the item;
q. transmitting the replenishment order to a vendor; and
r. incrementing the open order quantity by the Dynamic Order Quantity.

Abstract
A method using a central computer and a work station for managing inventory. To dispense inventory to consumers, a system user is issued a card imprinted with a personal user bar code. This user bar code is read into the computer and subsequently verified through the entry of individual user access data to ensure the user is authorized. To issue an item to a consumer, the user must next identify through an input means the particular consumer to whom the item is to be issued. The item to be issued is imprinted with an item bar code. After identifying the consumer, the item bar code is read into the work station and converted to issued-item data. The issued-item data is communicated from the work station to the central computer, where the issued item is decremented from inventory data. The central computer then determines whether each issued item is chargeable to the particular consumer. If the issued-item data is determined to be chargeable to the particular consumer, then the issued-item data is recorded as a charge to that consumer. Finally, the central computer determines when and in what quantity to replenish each item from the inventory data. A replenishment order is processed by the central computer, and the replenishment order is transmitted to a vendor.
