A project is modelled by the activity network shown in Figure 2. The activities are represented by the arcs. The number in brackets on each arc gives the time, in hours, to complete the corresponding activity.
- Complete Diagram 1 in the answer book to show the early event times and the late event times.
Each activity requires one worker and the project must be completed in the shortest possible time using as few workers as possible.
- Calculate a lower bound for the number of workers needed to complete the project in the shortest possible time. You must show your working.
- Schedule the activities using Grid 1 in the answer book.
