Expert Solution & Answer
Chapter 3, Problem 26PE
Explanation of Solution
Deriving Earliest Start Time, Earliest Finish Time and Slack:
Earliest Completion Time:
It is also known as Early Finish and is the amount required to complete the task of the project. The formula for calculating Early Finish is,
Latest Completion Time:
It is also known as Late Finish and is the latest time for the task to be completed. The formula for calculating Late Finish is,
Slack:
It is the amount of time that an activity can be delayed. It is the difference between Latest Finishing Time and Earliest Finishing Time,

By using network schedule technique, draw a Network Diagram of above enlisted activities.
1. Draw an Activity-On-Arrow (AOA) network diagram representing the project. Put the node numbers in circles and draw arrows from node to node, labelling each arrow with the activity letter and estimated duration.
2. Identify all the paths on the network diagram and note how long they are.
3. What is the critical path for this project and how long is it?
4. What is the shortest possible time needed to complete the project?

Construct a Gantt chart and network diagram for a project you are or will be involved in. Choose a project of sufficient depth from work, home, or school. Identify the activities to be completed, determine the sequence of the activities, and construct a diagram reflecting the starting times, ending times, durations, and precedence (network diagram only) relationships among all activities. For your network diagram, use the procedure in this chapter to determine time estimates for each activity and calculate the expected time for each activity. Now determine the critical path and the early and late starting and finishing times for each activity. Which activities have slack time?arrow_forward
