Assignment 2 (Due on or before 7/5/2021) The following diagram is the network diagram for a small project whose information relating to time and cost is given below. E Start End D Activity A B D E F G Time, days Normal Cm 3 2 2 1 5 3 $ 3 6 4 2 1 Normal 800 1.200 2.000 1.500 1.800 600 500 Costs Cros 1.400 1.900 2.800 2.300 2.800 1.000 1.000 a. Using normal times compute the ES. EF, LS. LF, and TS for each activity and identify the critical path. Also compute the total normal cost. b. If it is mandatory that this project be completed in 10 days, find the least- cost crash schedule and the corresponding total project cost to achieve it, if it can be achieved. Clearly indicate what jobs need to be crashed and by how many days
