ITM3207 Online Activity 2 Question 1 Based on the above table, answer the following questions: Activity A B C D E F G H Optimistic Time (a) 1 2 1 2 1 1 3 Most Likely Time (p) 2 3 2 4 4 Pessimistic Time (b) 3 4 3 6 7 2 4 2 Project Activity Table 9 11 3 Immediate Predecessor A B C C D. E F. G Expected Time (TE) 1. Refer to above Project Activity Table, construct the network scheduling diagram by using Activity On Arrow (AOA) method. 2. Calculate the expected time, TE for each activity. (Expected Time, TE = (a+4p+b)/6) (14 marks) (8 marks) 3. Calculate the Earliest Occurrence Time (EOT), Latest Occurrence Time (LOT) and Node Slack Time (NST) for each node. (7 marks) 4. Using an appropriate table, calculate the Earliest Starting Time (EST), Latest Starting Time (LST) and Activity Slack Time (AST). (16 marks) 5. Identify the all the possible paths and determine the critical path. (Smarks)
