Geox Ltd buys shoes from a supplier in Italy and sells them on to retailers in Australia. Geox Ltd currently uses an EOQ model to determine the number of shoes to send to order.

The annual demand for shoes is approximately 45,600.

The ordering cost is $55 per order.

The annual cost of physically storing shoes is $8.75 per unit.

The insurance on the inventory (shoes) cost is $4.25 per unit.

The opportunity cost (annual ROI 25% x $30) is $7.50 per unit.

The accountant of Geox Ltd, Richard Branson, recently attended a seminar on Just-in-Time (JIT) and is considering how the ideas of JIT differ from traditional techniques like EOQ and how they may help to manage inventory more efficiently.
