Introduction
Project 5 have three exercises: exercise 9 in chapter 6, exercise 2 in chapter 8, exercise 3 in chapter 9.
The solution to these three exercises will be completed by our team through our online discussion.
By doing these exercises we need to learn not only how to solve them, but also know what is its function during the real project.
The Solving Process
Question:
[pic 1]
Note: Do AON only network with all other requirements in terms of Moodle.
Solution:
AON network as follows:
Activity-On-Node Network Forward Pass
[pic 2]
Activity-On-Node Network Backward Pass

Activity-On-Node Network with Slack

How long will this project take?
According to the AON network shows there are three critical paths in this project: A-B-E-H-K-L, A-C-F-I-K-L and A-D-G-J-K-L.
And all the paths duration is 9 days. So this project will spend 9 days.
How sensitive is the network schedule?
We use the term sensitivity to reflect the likelihood the original critical path(s) will change once the project is initiated. Sensitivity is a function of the number of critical or near-critical paths.
In this project there are three critical paths and is no total slack. So we can identify this network schedule has high sensitive.
Calculate the free slack and total slack all noncritical activities
Free slack is the amount of time an activity can be delayed without delaying any immediately following (successor) activity. Total slack is the amount of time an activity can exceed its early finish date without affecting the project end date or an imposed completion date.
Hence in this exercise there is no free slack and total slack.
The project network helps to graphically present the sequence of activities within the start and finish times. In this exercise we’ve completed the forward and backward passes and have calculates free and total slack.
