Return to Exercise 6-1. Answer each of the following as well as possible from the results in Table 6.6.

(a) Is the optimal solution sensitive to the exact value of the trimming hours available?

At what number of hours capacity would it become relevant?

(b) How much should Super Slayer be willing to pay for an additional hour of extrusion time? For an additional hour of assembly time?

(c) What would be the profit effect of increasing assembly capacity to 580 hours?

To 680 hours?

(d) What would be the profit effect of increasing the profit margin on beta zappers by

$1500 per thousand? What would be the effect of a decrease in that amount?

(e) Suppose that the model of Exercise 6-1 ignores packaging capacity because it is hard to estimate, even though each thousand beta zappers requires 2 hours of packaging, and each thousand freeze phasers requires 3 hours. At what capacity would packaging affect the current optimal solution?

(f) Suppose that Super Slayer also has a Ninja Nailer model it could manufacture that requires 2 hours of extrusion, 4 hours of trimming, and 3 hours of assembly per thousand units? At what profit per thousand would it be economic to produce?
