Reconsider the Fly-Right Airplane Co. problem introduced in Prob. 12.3-7.

A more detailed analysis of the various cost and revenue factors now has revealed that the potential profit from producing airplanes for each customer cannot be expressed simply in terms of a start-up cost and a fixed marginal net revenue per airplane produced. Instead, the profits are given by the following table.

(a) Formulate a BIP model for this problem that includes constraints for mutually exclusive alternatives.

C

(b) Use the computer to solve the model formulated in part (a).

Then use this optimal solution to identify the optimal number of airplanes to produce for each customer.

(c) Formulate another BIP model for this model that includes constraints for contingent decisions.

C

(d) Repeat part

(b) for the model formulated in part (c).
