The network in Figure 5 shows the activities involved in a process. The activities are represented by the arcs. The number in brackets on each arc gives the time, in days, taken to complete the activity.
- Calculate the early time and the late time for each event, showing them on the diagram in the answer book.
- Determine the critical activities and the length of the critical path.
- Calculate the total float on activities F and G . You must make the numbers you used in your calculation clear.
- On the grid in the answer book, draw a cascade (Gantt) chart for the process.
Given that each task requires just one worker,
- use your cascade chart to determine the minimum number of workers required to complete the process in the minimum time. Explain your reasoning clearly.
