Grand Pizza Inc. produces two pizza products. Letting
C= number of Cheese pizzas
D= number of Double pizzas
leads to a formulation:
Max z = 2 C + 2.5 D
s.t.
10 C + 14 D ? 8960 Dough
6 C + 2 D ? 4160 Cheese
4 C + 4 D ? 3200 Tomatoes
C, D ? 0
The Excel solution is enclosed.
a. What is the optimal objective function value, and what are the optimal values of variables?
b. Specify the range of optimality for the objective function coefficients.
c. What are the shadow prices for each constraint? Interpret each.
d. Identify the range of feasibility for each of the right hand side values (i.e.
in what range the shadow price for a constraint is valid).
