The following diagram is the network diagram for a small project whose information relating to time and cost is given below. 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. 1:. [fit is mandatory that this project he completed in 10 days, nd the least- cost crash schedule and the corresponding total Erg'ect cost to achieve it. if it can he achieved. Clearly indicate what jobs need to be crashed and by how many days
