Figure 7 shows an activity network. Each activity is represented by an arc and the number in brackets on each arc is the duration of the activity in days.
- Complete Figure 7 in the answer book showing the early and late event times.
- List the critical path for this network.
The sum of all the activity times is 95 days and each activity requires just one worker. The project must be completed in the minimum time.
- Calculate a lower bound for the number of workers needed to complete the project in the minimum time. You must make your method clear.
- On the grid in your answer book, draw a cascade (Gantt) chart for this network.
