Question 18
What are the two principles when crashing a project?
|
Focus on the critical path, select the least expensive alternative. |
||
|
Reduce the cost, reduce the duration. |
||
|
Reduce the duration, increase the cost. |
||
|
Reduce the use of resources, reduce the cost |

Question 24
Which of the following effects will be observed in a network if a date-constrained project is scheduled from the ending date constraint using the “as late as possible” heuristic?
|
Eacy activity will have zero slack and be located on the critical path. |
||
|
The network will not have any critical activities because everything can be done prior to the final date constraint. |
||
|
It would never be possible to override the "as late as possible" heuristic with a "must start no later than" date constraint. |
||
|
It would never be possible to schedule an activity prior to the start date of the project. |

Question 18
Correct answer is Focus on the critical path, select the least expensive alternative.
During crashing we need to Focus on the critical path, select the least expensive alternative.
Question 19
Correct answer is (Crash cost - normal cost) / (crash time - normal time)
The formula for computing the cost/time slope for each activity that can be crashed is (Crash cost - normal cost) / (crash time - normal time)
Question 20
Correct answer is Fast-tracking
The Fast-tracking schedule compression technique overlaps the design and builds phases of a project to expedite its completion
Question 21
Correct answer is Alternatives for trade-offs between time and resources
The points between the extreme points of the relationship between time use and resource use represent Alternatives for trade-offs between time and resources
Question 22
Correct answer is 13
expected time using the beta statistical distribution = (optimistic+pessimistic+4*most likely time)/6 = (10+20+4*12)/6 = 13
Question 23
Correct answer is as late as possible
The usual purpose of the as late as possible scheduling heuristic is to delay cash outflows as long as possible.
Question 24
Correct answer is Each activity will have zero slack and be located on the critical path.
In “as late as possible” heuristic , each activity will make use of all the available slack
Question 25
Correct answer is 18
Given that task A will use three carpenters and have duration of six days, task A requires 18 labor days of work.
