Perspective 7-5: Combine the EOQ formula with Figure 7-8 to clearly illustrate the impact
of selecting the optimum order size.
PPT Determining the Optimum Inventory Level (Figure 7-8)
I. Assumptions of the basic EOQ model:
1. Inventory usage is at a constant rate.
2. Order costs per order are constant.
3. Delivery time of orders is consistent and order arrives as inventory
reaches zero.
J. Minimum total inventory costs will result if the assumptions of the model are
applicable and the firm’s order size equals the economic ordering quantity.
Finance in Action: NASAThe National Aeronautics and Space Administration Inventory
Control System
This box illustrates how the use of technology can save time and reduce costs. NASA, with the
help of their prime contractor United Space Alliance (USA), have installed a radio frequency
data communications system which can pinpoint 98 percent of the 300,000 inventory items
found among 100 buildings in a matter of seconds. This system saves almost $1 billion annually
by reducing the time it takes to locate equipment.
K. Just-in-Time Inventory Management (JIT)
1. Began in Japan and now used in the U.S.
2. Suppliers are located near manufactures who are able to make orders in
small lot sizes because of short delivery time.
3. Lower inventory means lower costs
4. The downside of (JIT) is that any glitch in delivery can shut down the
whole production process. In 2011 the Tsunami in Japan and the floods in
Thailand are good examples of unexpected events that can cause huge
problems for companies using just-in-time inventory systems.
