can sometimes

can never

Question 10.10.For a linear programming problem, assume that a given resource has not been fully used. We can conclude that the shadow price associated with that constraint: (Points : 5)

will have a positive value.

will have a negative value.

will have a value of zero.

Question 13.13.Mallory 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 Mallory Furniture company decides to purchase 150 big shelves and no medium shelves, which of the two resources will be left over? (Points : 5)

Investment money only

Storage space only

Investment money and storage space

Neither investment money nor storage space

Question 14.14. A linear programming model consists of: (Points : 5)

decision variables

an objective function

constraints.

all of the above

Question 15.15.The term refers to testing how a problem solution reacts to changes in one or more of the model parameters. (Points : 5)

Priority recognition

Decision analysis

Analysis of variance

Sensitivity analysis

Question 16.16.If a maximization linear programming problem consists of all less-than-or-equal-to constraints with all positive coefficients and the objective function consists of all positive objective function coefficients, then rounding down the linear programming optimal solution values of the decision variables will ________ result in a(n) ________ solution to the integer linear programming problem. (Points : 5)

always; optimal

always; non-optimal

never; non-optimal

sometimes; optimal

Question 17.17.Decision variables: (Points : 5)

measure the objective function

measure how much or how many items to produce, purchase, hire, etc.

always exist for each constraint

measure the values of each constraint

Question 18.18.Cully Turniture 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. 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

unequal to

equal to

linear to

parallel to
