The fired heater example in Figure 2.11 had a hard constraint.

(a) Sketch the performance function for this situation, including the performance when

violations occur, on the figure.

(b) Assume that the distribution of the temperature would have 0.005 fraction of its

operation exceeding the limit of 864°C and that each time the limit is exceeded, the

plant incurs a cost of $1000 to restart the equipment. Can you calculate the total cost

per year for exceeding the limit?
