Given: The activities constituting a project, their immediate predecessors, the normal duration (in days) and cost (in $) of each activity, as well as the crash duration (in days), and crash cost (in %) of each are listed in the table below. Activity Imm. Normal Normal Crash Crash Pred. Dur. Cost Dur. Cost A 7 500 4 800 A 00 B A 3 200 2 350 C 6 500 4 900 D C 3 200 1 500 E B,D 2 2 300 1 900 Required: 1. Draw the network diagram. 2. Calculate ES, EF, LS, LF values for each activity. V 3. Calculate the slack values for each activity, identify the critical path, and the normal duration and normal cost of the project. 4. Calculate "crash cost per day" values for each activity. 5. Reduce the duration of the project one day at a time, until the project reaches its crash duration, showing which activities must be crashed for each day of reduction, and at what cost. 6. Calculate the crash cost of the project. 7. What conclusions do you reach on the relationship of normal versus crash costs, and durations. Act stock Slock cost/ non
