Sanderson Manufacturing produces ornate, decorative wood frame doors and windows. Each item produced goes through three manufacturing processes: cutting, sanding, and finishing. Each door produced requires 1 hour in cutting, 30 minutes in sanding, and 30 minutes in finishing. Each window requires 30 minutes in cutting, 45 minutes in sanding, and 1 hour in finishing. In the coming week, Sanderson has 40 hours of cutting capacity available, 40 hours of sanding capacity, and 60 hours of finishing capacity. Assume all doors produced can be sold for a profit of $500, and all windows can be sold for a profit of $400. Supply Management Assignment Help
a. Formulate an LP model for this problem.
b. Sketch the feasible region.
c. What is the optimal solution?
The Beef-Up Ranch feeds cattle for Midwestern farmers and delivers them to processing plants in Topeka, Kansas, and Tulsa, Oklahoma. The ranch must determine the amounts of cattle feed to buy so that various nutritional requirements are met while minimizing total feed costs. The mixture fed to the cows must contain different levels of four key nutrients and can be made by blending three different feeds. The amount of each nutrient (in ounces) found in each pound of feed is summarized as follows: Supply Management Assignment Help Nutrient (in ounces) per Pound of Feed Nutrient Feed 1 Feed 2 Feed 3 A 3 2 4 B 3 1 3 C 1 0 2 D 6 8 4 The cost per pound of feeds 1, 2, and 3 are $2.00, $2.50, and $3.00, respectively. The minimum requirement per cow each month is 4 pounds of nutrient A, 5 pounds of nutrient B, 1 pound of nutrient C, and 8 pounds of nutrient D. However, cows should not be fed more than twice the minimum requirement for any nutrient each month. (Note that there are 16 ounces in a pound.) Additionally, the ranch can only obtain 1,500 pounds of each type of feed each month. Because there are usually 100 cows at the Beef-Up Ranch at any given time, this means that no more than 15 pounds of each type of feed can be used per cow each month.
a. Formulate a linear programming problem to determine how much of each type of feed a cow should be fed each month.
b. Create a spreadsheet model for this problem, and solve it using Solver
