The difference between free float and slack of the tail event is called as
- ATotal float
- BInterfering float
- CIndependent floatCorrect
- DLatest finish time
Solution
Concept
Independent float definition in network analysis
Formula
NONE
Step-by-step solution
1. Float and slack reflect time flexibility available within project network activities. 2. Independent float accounts for tail event slack and head event slack. Answer: C
Explanation
Independent float represents the amount of time an activity can be delayed without affecting either preceding or succeeding activities. Mathematically, it is defined as the free float minus the slack of the tail event. Therefore, option C is the correct choice.
Why the other options are wrong
A) Total float is the total delay an activity can suffer without delaying project completion. B) Interfering float is the portion of total float that restricts the float of subsequent activities.
Shortcut
Independent Float = Free Float - Tail Event Slack.
Common mistake
Confusing independent float with total float or interfering float formulas.
Correct answer: C) Independent float
