Question 5. 5. Cully Turniture buys two products for resale: big shelves (B) and medium shelves (M).

What is the storage space constraint? (Points : 5)

90 B + 100 M = 18000

90 B + 100 M = 18000

100 B + 90 M = 18000

500 B + 300 M = 18000

Question 6. 6. In a 0-1 integer programming model, if the constraint x1 – x2 = 0, it means when project 2 is selected, project 1 ________ be selected. (Points : 5)

must always

can sometimes

can never

Question 7. 7. Which of the following is not an integer linear programming problem? (Points : 5)

Pure integer

Mixed integer

0-1 integer

Continuous

Question 8. 8. The \$75 per credit hour course fee tacked on to all the MBA classes has generated a windfall of \$56,250 in its first semester. “Now we just need to make sure we spend it all,” the Assistant Dean cackled. She charged the Graduate Curriculum Committee with generating a shopping list before their next meeting. Four months later, the chairman of the committee distributed the following. As the professor for the quantitative modeling course, he tended to think in terms of decision variables, so he added the left-most column for ease of use.

Decision

Variable Item Cost Note

A iPads for everybody \$750/unit Must get a cover if these are purchased

B iPad covers with MBA logo \$25/unit Not needed unless we buy iPads

C Speaker series \$15,000 Can’t afford both this and the iPads

D Subscriptions to the Wall

Street Journal \$10/unit Don’t need if we have the electronic version

E Subscriptions to the electronic

version of the Wall Street

Journal \$5/unit Worthless without the iPads

Which constraint best describes the situation with decision variables A and B? (Points : 5)

B – A = 0

B + A = 0

B + A = 1

B – A = 1

Question 9. 9. Non-negativity constraints: (Points : 5)

require the use of greater-than-or-equal-to constraints.

restrict the decision variables to positive values.

restrict the decision variables to negative values.

do not restrict the sign of the decision variable.

Question 10. 10. Which of the following could be a linear programming objective function? (Points : 5)

Z = 1A + 2BC + 3D

Z = 1A + 2B + 3C + 4D

Z = 1A + 2B / C + 3D

Z = 1A + 2B2 + 3D

Question 11. 11. A graphical solution is limited to linear programming problems with: (Points : 5)

1 decision variable.

2 decision variables.

3 decision variables.

4 decision variables.

Question 12. 12. The term refers to testing how a problem solution reacts to changes in one or more of the model parameters. (Points : 5)

Question 16. 16. The \$75 per credit hour course fee tacked on to all the MBA classes has generated a windfall of \$56,250 in its first semester.“Now we just need to make sure we spend it all,” the Assistant Dean cackled.

Question 18. 18. Cully Furniture buys two products for resale: big shelves (B) and medium shelves (M). Each big shelf costs \$500 and requires 100 cubic feet of storage space, and each medium shelf costs \$300 and requires 90 cubic feet of storage space. The company has \$75,000 to invest in shelves this week, and the warehouse has 18,000 cubic feet available for storage. Profit for each big shelf is \$300 and for each medium shelf is \$150. If the furniture company purchases no big shelves and 200 medium shelves, which of the two resources will be completely used (at capacity)? (Points : 5)
