including a positive reputation for quality, increased customer loyalty, and lower
production costs.
5) The process of dismantling and inspecting a competitor's product to discover product
improvement is called benchmarking.

TQM; they should worry about their own problems.
7) In the lean approach, inventories are reduced gradually, instead of eliminating
inventories as rapidly as possible.
8) Quality function deployment is a structured approach that guarantees that the
highest-quality product or service will be designed.
9) Poor quality has a positive effect on productivity because it usually takes longer to
produce a good part.
10) Quality certification refers to a process of 100 percent inspection to catch all
defective products before they leave the company; this allows every item to be certified
defect free.

batch production.
12) Wage and salary increases that are not accompanied by productivity increases tend
to exert inflationary pressures on a nation's economy.

16) The production planner for a private label soft drink maker is planning the
production of two soft drinks: root beer (R) and sassafras soda (S). Two resources are
constrained: production time (T), of which she has at most 12 hours per day; and
carbonated water (W), of which she can get at most 1,500 gallons per day. A case of
root beer requires 2 minutes of time and 5 gallons of water to produce, while a case of
sassafras soda requires 3 minutes of time and 5 gallons of water. Profits for the root
beer are $6.00 per case, and profits for the sassafras soda are $4.00 per case. What is the
production time constraint (in minutes)?
17) An analyst, having solved a linear programming problem, determined that he had 10
more units of resource Q than previously believed. Upon modifying his program, he
observed that the optimal solution did not change, but the value of the objective
function increased by $30. This means that resource's Q's shadow price was:
A.$1.50.
B.$3.00.
C.$6.00.
D.$15.00.
E.$30.00.
18) The mean absolute deviation is used to:

handling, and possibly robots is called:
A.computer-aided design.
B.a manufacturing cell.
C.computer-aided manufacturing.
D.computer-integrated manufacturing.
E.a flexible manufacturing system.

because of:
A.fixed costs increasing.
B.automation.
C.mass production.
D.increases in indirect labor.
E.greater precision in estimating the learning rate.
21) The production planner for Fine Coffees, Inc., produces two coffee blends:
American (A) and British (B). Two of his resources are constrained: Columbia beans, of
which he can get at most 300 pounds (4,800 ounces) per week; and Dominican beans,

American blend coffee requires 12 ounces of Colombian beans and 4 ounces of
Dominican beans, while a pound of British blend coffee uses 8 ounces of each type of
bean. Profits for the American blend are $2.00 per pound, and profits for the British
blend are $1.00 per pound. What is the Columbia bean constraint?
