Table 4.2
High Tech, Inc. is producing two types of products: A and B. Both are produced at the same sawing operation. Because of demand uncertainties, the operations manager obtained three demand forecasts (pessimistic, expected, and optimistic) . The demand forecasts, batch sizes (units/batch) , processing times (hr/unit) , and setup times (hr/batch) follow.

$\begin{array}{c}\quad\quad\quad\quad\quad\text { Time Standard } \quad\quad \quad\quad\quad\quad\quad \text { Demand Forecasts ( 000 units/yr) }\\\begin{array}{|l|l|l|l|l|l|l|}\hline \text { Product } & \text { Processing } & \text { Setup } & \text { Batch Size } & \text { Pessimistic } & \text { Expected } & \text { Optimistic } \\\hline \text { A } & .20 & 2.0 & 40 & 200 & 240 & 300 \\\text { B } & .15 & 3.0 & 50 & 160 & 180 & 200 \\\hline\end{array}\end{array}$
