3.2 Consider the time-cost table below and its network. Suppose indirect cost is $1.50 per day. Consider only the direct cost presented in the table below. Perform the time-cost trade-off method and identify all possible alternatives. Normal Crash Normal Crash Activity Time Time Cost Cost Ꭰ A 4 3 10 15 2 B 6 4 C D 9 E F 22 7864 6 985 45 13 12 19 B 13 22 E 3 8 10 F 4.2 Consider exercise 3.2. Only consider the network and the normal times given in exercise 3.2. Use the LP approach to find the project duration. Also, identify earliest times and latest times for all activities and the critical path by using LP.
