Deck 38: Network Planning and Analysis

Question 1

Which of the following statements about float is NOT true?

A) Float is used to make sure that the total duration of the path fits with the expected completion date
B) Float may not be added to activities on the critical path without extending the critical path
C) Total float is the amount of time which can be added without creating a new critical path
D) Free float is the amount of time which can be added to an activity without affecting the float of subsequent activities

Answer 1

Float is used to make sure that the total duration of the path fits with the expected completion date

Question 2

What is the basic process for calculating the event late time for an event in the middle of a network diagram?

A) Add the duration of the preceding activity (to the left) to its early time
B) Subtract the duration of the preceding activity (to the left) to its early time
C) Add the duration of the following activity (to the right) to its early time
D) Subtract the duration of the following activity (to the right) to its early time

Answer 2

Subtract the duration of the following activity (to the right) to its early time

B) Dummy activities always have no time associated with them
C) Dummy activities may be used to preserve the correct order of activities
D) Dummy activities are used to ensure that skilled workers do the most important jobs

Question 9

Which of the following options is the BEST definition of a critical path?

A) The path through a network with the longest duration
B) The path through a network with the shortest duration
C) The path through a network with the most important duration
D) The path through a network where mistakes are most likely to occur

Question 10
