Quiz 3

Question 1.1.Which of the following statements about project crashing is false?(Points : 3)
The overall project time is reduced by crashing activities on one or more critical paths.
It is best to crash an activity with the cheapest cost to crash per week.
As activities are crashed in a project network, it is possible for more than one path to be critical.
In order to reduce the overall project time, it may be necessary to crash more than one activity.
Project crashing problems can be solved using linear programming.
