Which of the following statements about time-series forecasting is true?
A) It is based on the assumption that future demand will be the same as past demand.
B) It makes extensive use of the data collected in the qualitative approach.
C) It is based on the assumption that the analysis of past demand helps predict future
demand.

An organization is considering three process configuration options. There are two
different intermittent processes, as well as a repetitive focus. The smaller intermittent
process has fixed costs of $3,000 per month, and variable costs of $10 per unit. The
larger intermittent process has fixed costs of $12,000 per month and variable costs of $2
per unit. A repetitive focus plant has fixed costs of $50,000 and variable costs of $1 per
unit.
a. If the company produced 20,000 units, what would be its cost under each of the three
choices?
b. Which process offers the lowest cost to produce 40,000 units? What is that cost?
The components, their description, and the quantity of each required to make one unit
of a product are documented on
A) a group technology listing
B) a route sheet
C) a bill of material
D) an engineering drawing
E) none of the above

Provide examples of non-monetary incentives.
Industrial firms choose locations that minimize cost, but service firms look for locations
with good demographics and traffic count because these variables are indicators of good
__________.
Two methods of conducting sensitivity analysis on solved linear programming problems
are __________ and __________.
A distribution of service times at a waiting line shows that service takes 6 minutes 40
percent of the time, 7 minutes 30 percent of the time, 8 minutes 20 percent of the time,
and 9 minutes 10 percent of the time. Prepare the probability distribution, the
cumulative probability distribution, and the random number intervals for this problem.
__________ are a way of allowing a segment of the master schedule to be designated as
"not to be rescheduled."
A toy manufacturer makes stuffed kittens and puppies which have relatively lifelike
motions. There are three different mechanisms which can be installed in these "pets."
These toys will sell for the same price regardless of the mechanism installed, but each
mechanism has its own variable cost and setup cost. Profit, therefore, is dependent upon
the choice of mechanism and upon the level of demand. The manufacturer has in hand a
forecast of demand that suggests a 0.2 probability of light demand, a 0.45 probability of
moderate demand, and a probability of 0.35 of heavy demand. Payoffs for each
mechanism-demand combination appear in the table below.
Construct the appropriate decision tree to analyze this problem. Use standard symbols
for the tree. Analyze the tree to select the optimal decision for the manufacturer.
