Figure 2 shows an activity network. The nodes represent events and the arcs represent the activities. The number in each bracket gives the time, in days, needed to complete the activity.
- Calculate the early and late times for each event using appropriate forward and backward scanning.
(5 marks) - Hence, determine the activities which lie on the critical path.
- State the minimum number of days needed to complete the entire project.
