Problem 2: For a Student Dormitory Project, an estimated normal time with an associated normal cost is given for each activity. Crash times, the minimum duration required to complete each activity, and their associated crash costs are also given. Time (weeks) Cost (in TL) Activit Immediate Predecessors Feasible Time reduction in weeks Normal Crash Normal Crash Crash cost/week A 2 2 40000 40000 0 B 3 2 48000 56000 1 8000 B 4 3 80000 85000 1 5000 D A, C 5 4 55000 59000 1 4000 E B 5 3 90000 98000 2 4000 F 7 4 75000 84000 3 3000 G 4 3 25000 32000 1 7000 D, F E, G H 2 2 15000 15000 0 Assignment: Draw the project network. For normal situation, calculate the earliest start and finish times and latest start and finish times of all activities, define critical path and normal completion time of the project. Administration requests the project time to be reduced 4 weeks. Therefore, crash the project 4 weeks down from its normal completion time. Answer the following questions. Questions: Write the critical path and expected normal project completion time. What is the project cost for normal completion time? Write the activities crashed and their crashing costs in each step to reach total 4 weeks reduction in the project time? Write the reduced project time and total project cost after crashing
