Essay

A company is expanding its production capacity. The decision will depend upon whether the increase in demand is low, medium, or high. The company's choices for expansion are small, medium, large, or very large. The following table provides an estimate of profits over the next two years. $\begin{array}{l|ccc}&&\text { Demand Values }\\\text { Decision } & \text { Low }\left(\mathrm{S}_{1}\right) & \text { Medium }\left(\mathrm{S}_{2}\right) & \text { High }\left(\mathrm{S}_{3}\right) \\\hline\text { Small Expansion }\left(\mathrm{d}_{1}\right) & \$ 5,000 & \$ 10,000 & \$ 10,000 \\\text { Medium Expansion }\left(\mathrm{d}_{2}\right) & \$ 2,000 & \$ 12,000 & \$ 14,000 \\\text { Large Expansion }\left(\mathrm{d}_{3}\right) & 0 & \$ 6,000 & \$ 13,000 \\\text { Very Large Expansion }\left(\mathrm{d}_{4}\right) & \$ 5,000 & \$ 8,000 & \$ 20,000\end{array}$
