TURE OR FALSE: 1. A predecessor activity is one that must be accomplished before

Question

TURE OR FALSE:

1. A predecessor activity is one that must be accomplished before the given activity can be started

2. The CPM assigns just one time estimate to each activity while PERT employs a probability distribution based on three time estimates for each activity

3. Gantt charts contain information about the time taken by each activity, but not about the sequential dependencies of the activities

4. Simulation models are designed to generate optimal solution, which can then be applied to real-world situation

5. Simulation does not interfere with the real world system

6. If we are using a Monte Carlo simulation model, the average simulation demand must be equal to the expected demand

Explanation / Answer

1) True

The predecessor event is an event that must be completed before a specified activitycan begin.

2) True

CPM assigns just one time estimate toeach activity and this is used to find the critical path. • In many projects there is uncertainty aboutactivity times o PERT employs a probability distribution based on three time estimates for each activity,

3) True

4) False.

Simulation modls cannot generate an optimal solution. They only provide a solution that is closest to the realistic and best-feasible situation.
