A. Formulate a linear programming model for Mossaic Tiles, Ltd., and determine the mix of tiles it should manufacture each week.
B. Transform the model into standard form.
C. Determine the resources left over and not used at the optimal solution point.
D. Determine the sensitivity ranges for the objective function coefficients and constraint quantity values by using the graphical solution of the model.
E. For artistic reasons, Gilbert and Angela like to produce the smaller, patterned tiles better. They also believe that in the long run, the smaller tiles will be a more successful product. What must the profit be for the smaller tiles in order for the company to produce only the smaller tiles?
F. Solve the linear programming model by using the computer and verify the sensitivity ranges computed in (E).
G. Mossaic believes it may be able to reduce the time required for molding to 16 minutes for a batch of larger tiles and 12 minutes for a batch of the smaller tiles. How will this affect the solution?
H. The company that provides Mossaic with clay has indicated that it can deliver an additional 100 pounds each week. Should Mossaic agree to this offer?
I. Mossaic is considering adding capacity to one of its kilns to provide 20 additional glazing hours per week, at a cost of $90,000. Should it make the investment?
J. The kiln for glazing had to be shut down for 3 hours, reducing the available kiln hours from 40 to 37. What effect will this have on the solution?
