For a 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. Draw the AON diagram. Determine the ES, EF, LS, LF times and critical path. Crash the project to 12 weeks by explaining each crashing step. Determine the total project cost after crashing.
