Ferrer Ltd buys hats from a supplier in Sri Lanka and sells them on to retailers in Australia. Ferrer currently uses an EOQ model to determine the number of hats to send to order.

Annual demand for hats is approximately 26 400. The ordering cost is $125 per order and the annual carrying cost of a hat is $1.75.

Ferrer's accountant, Andrew Murray, 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.
