The Harmon Music Company produces a variety of wind instruments at its plant in Joliet,

Illinois. Because the company is relatively small, it would like to minimize the amount of money

tied up in inventory. For that reason, production levels are set to match predicted demand as

closely as possible. In order to achieve this goal, the company has adopted an MRP system to

determine production quantities. One of the instruments produced is the model $85$C trumpet.
