Which of the following is not a decision variable when formulating the project crashing problem as a linear program?
A)the early finish times of critical activities
B)the early finish times of noncritical activities
C)the finish time of the project
D)the early start times of all activities

Question

Quizplus · Accepted Answer

The early start times of all activities are not a decision variable in the project crashing problem as they are fully determined by the early finish times and activity durations. The decision variables are the amount of time each activity is crashed or expedited. The other options, A, B, and C, are all decision variables that need to be determined in the linear program to minimize the project duration while meeting certain constraints.
