Given the information in the table below, draw the PERT chart and determine the critical path using the ECT, LCT, and slack time approach.

Starting node Ending node Activity Time (weeks)

1 2 1-2 2

1 3 1-3 7

2 3 2-3 4

2 4 2-4 3

3 4 3-4 2

Page 60 discusses how Activity 1-3 can be reduced by 1 week at the cost of $500.

Question 1, Practice Exercises, on page 61 of Unit 2s PDF text:

Attempt to reduce project completion time in the previous example by an additional two weeks. What do you notice about the critical path? How should you proceed to accomplish this objective?

You are required to:

Calculate the Critical Path for Activity 2.2 using both methods:

• Slack Time, and
• All Paths.

Include the table with headings: Activity, T, M, C, K, CP

Reduce the project by 2 additional weeks as required in Question 1:

• Identify which activity is to be reduced for each week (show all working).
• State the total cost for a 3-week reduction.

NOTE:

The Dia program is not necessary for this question.
