The network and durations given in Figure 1 below shows the normal schedule for a project. Duration of the project can be crashed at an additional cost. The Table 1 given below. Summarizes the time-cost information for the activities. A 24 B c D E 1 2 3 6 10 F 12 Figure 1 Activity Normal Cost Crash Cost (Pounds) (Pounds) Crash Duration (Days) 20 3 6 |q Normal Duration (Days) 24 4 8 6 10 12 A B D 2400 360 3200 280 720 2700 2800 560 4400 400 960 3600 8 9 Table 1 (0) Identify the project critical path and critical activities. (ii) Calculate the duration of the project. (iii) The customer wants you to finish the project in 22 days. Find the minimum possible cost for the project if you want to finish it on 22 days. (Assume that for each activity there is a single linear, continuous function between the crash duration and normal duration points)
