a) b) c) Construct an Activity On Arrow AOA network based on the table Q3. The time is in weeks. Propose critical path and another TWO (2) possible paths other than critical path, with information on the total project time. Compute a cost/time slope for each activity that can be crashed. (4 marks) Evaluate the time and cost factor, propose a solution where the project can be shortened to 12 weeks and what are the total cost required by modifying the critical path?
