QUESTION
Business is booming at Charlie's bakery. Almost every type of bread sells out daily, and the
ovens are at 100% capacity. If Charlie wants to grow his business, he needs more oven capacity
to bake more bread. However, he is concerned that if he invests in more capacity, demand may
be lower than expected.
How would a decision tree help Charlie in this situation?
O It would determine the break-even point using what-if analysis in calculating the expected
payoff to expand oven capacity.
O It would incorporate the probabilities of different demand levels in calculat- ing the expected
payoff to expand oven capacity.
O It would identify multiple alternatives to determine the highest payoff in order to expand oven
capacity.
O It would incorporate multiple states of nature for determining which alter- native has the
highest payoff to expand oven capacity.
Answer:
It would incorporate the probabilities of different demand levels in calculating the expected
payoff to expand oven capacity.
QUESTION
An employee has been asked to decide which machine to choose from four possibilities. The
purchase and installation cost for each machine is identical. The decision tree below describes
the conditions and expected
values.
Which machine should this employee select? O Machine B
O Machine A O Machine C
O Machine D
Answer:
Machine A
Rationale::
Machine A is (100000x.25)+(50000x.75)=62500 highest probability of produc- tivity
and Machine B is (100000x.50)+(0x.50)=50000
and Machine C is (50000x.40)+(25000x.60)=35000 and Machine D is (250000x.25)+(50000x.75)=25000
QUESTION
Bob is opening a new location for his popular sandwich shop. The PERT
chart for this project is provided below:
What is the duration of the critical path for this project?
O 14 weeks
O 16 weeks
O 13 weeks
O 27 weeks
Answer:
16 weeks
Rationale::
critical path is the highest value and 10+3+3=16 and 6+4+1+3=14
QUESTION
. The PERT chart for a project is shown below:
What is the critical path for this project? O E-G-J
O A-B-J O E-F-J
O C-D-F-J
O H-I-J
Answer:
A-B-J
Rationale::
the critical path is the highest value so 25+9+5=39
QUESTION
. A construction company is working on a project to build a new industri- al office park. A local
television station was planning to film the construction project and
conduct interviews with key stakeholders to create a documentary (activity
F), but the filming has just been cancelled. The original PERT chart is shown
below:
Now that activity F has been cancelled, what is the critical path for this project? O C-G-H-I
O B-E-I
O B-E-G-H-I
O A-D-I
Answer:
B-E-G-H-I
Rationale::
the highest value or critical path is 18+4+6+4+7=39 and 11+4+7=22 and 12+6+4+7=29
QUESTION
. The PERT chart below shows activities and duration's for a project.
What is the critical path for this project? O A-B-C-K
O I-J-K
O F-G-H-K
O A-B-D-E-K
O F-G-J-K
Answer:
F-G-J-K = 22+10+15+10 = 57 Rationale::
the critical path is the highest value so
A-B-C-K = 20+4+11+10 = 45
A-B-D-E-K = 20+4+2+5+10 = 41
F-G-H-K = 22+10+9+10 = 51
I-J-K = 21+15+10 = 46
QUESTION
. Based on the above network of activities, what is the value for step E, if the path A-B-E-F-G
has a total completion time of 17 days?
O 2 days O 1 day O 3 days
O 4 days
