II. The following network represents a project and shows the activities with their durations. The attached table also shows the normal and crash times and costs for all activities. (20%) (1) Try to compress project durations day by day, and fill in your answers in the appropriate cells of the attached table. (You don't need to fill in the cells associated with project durations where the corresponding compression is impossible.) (15%) (2) Assume that the indirect cost for this project...

A simple CPM network has three activities, A, B, and C. A is an immediate predecessor of B and of C. B is an immediate predecessor of C. The activity durations are A=4, B=3, C=5. The network has no critical path. The critical path cannot be determined without knowing PERT expected activity times. The critical path is A-C, duration 10.5. The critical path is A-B-C, duration 9. The critical path is A-B-C, duration 12.

The table below defines the activities and the normal time duration for each activities within a small project. You can decrease (crash) the durations at an additional expense. Table 1 summarizes the time-cost information for the activities to complete the project. Table 1: The time-cost information for the activities Activity Normal Completion Time (weeks) Immediate Predecessor Crash Time (weeks) Normal cost for activities Crash cost for activities/week A 2 - 1 1200 400 B 3 - 1 1400 500 C...
