(a) What do you understand by sensitivity analysis? Why is it important? How can you use the sensitivity ranges to decide whether your recommendations based on the optimal solution of a linear programming problem are robust or not? (b) What is an assignment problem? Briefly discuss the decision variables, the objective function and the constraint requirements in an assignment problem. How do we determine whether a given assignment problem is balanced? Give a real-world example of the assignment problem. (c)...

The Surest Concrete Company produces cement in a continuous process. Two ingredients in the cement are sand, which Surest purchases for $8 per ton, and gravel, which costs $10 per ton. The other ingredients are lumped together and referred to as “Other”. The cost of the other ingredients is $7 per ton. No more than 40 percent of the cement can be sand, and at least 30 percent of the cement must be gravel. The maximum amount of gravel available is 100 tons. The...

MSA Computer Corporation manufactures three models of computers: the Alpha4, Beta5, and the Delta6. The firm employs thirteen technicians working 160 hours each per month on its assembly line. Management insists that no more than full employment on the assembly line (i.e., all 160 hours of time) can be maintained for each worker during next month’s operations, so there will be no overtime. It requires 20 labor hours to assemble each Alpha4 computer, 25 labor hours for each Beta5 model,...
