The product structure diagram for the ICU$2$ computer is given in Figure $8-6.$

Suppose that the forecasted demands for the computer for weeks $6$ to $11$ are

$220,165,180,120,75,300.$ The starting inventory of assembled computers in

week $6$ will be $75,$ and the production manager anticipates returns of $30$ in week $8$

and $10$ in week $10.$
