1. If the objective function is to Minimize -x + 2y, which of points A, B, C, D is optimal? a. Point A b. Point B c. Point C d. Point D 2. If the objective function is to Maximize 3x + 5y, which of points A, B, C, D will be optimal? 3. At which of the points A, B, C, D does constraint 3 have a surplus (is not binding)? 4. If x – y 2 is added as an additional constraint, which of the points A, B, C and D will still be feasible? 5. Which of the following changes would make the feasible region infeasible (empty)? a. Add y 6 as a new constraint b. Add x + y 5 as a new constraint c. Add x 7 as a new constraint d. Delete constraint 3 6. Which of the following changes would make the feasible region unbounded? 7. Which of the following are components of a mathematical model for decision making? 2
Which of the following statement(s) on linear programming models is/are correct? I. If a linear programming model has an optimal solution, then the feasible region cannot be empty. II. In order to obtain a feasible solution to an otherwise infeasible problem, some of the constraints must be relaxed. III. Changing the objective function will never make an infeasible problem feasible. 9. Which of the following cannot be a reason for conducting sensitivity analysis? a. Some of the input parameters of the model may not have been known with certainty. b. Some of the input parameters of the model are approximations or estimates. c. The model represents a dynamic environment in which some of the parameters are subject to change by time. d. None of the above.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
