H | Consider the project shown above. Max Crash time indicates the most number of weeks that can be crashed (Normal time - crash time). 1.0 Draw the network diagram and find the critical path, time and cost for an all-normal level of project activity. 2.0 Calculate the crash cost-per-week assuming that all activities may be partially crashed (except Task A, which cannot be crashed). 3.0 Which tasks should be crashed to do the project in 11 weeks? What is the cheapest project cost for that time? 4.0 Which tasks should be crashed to do the project in 10 weeks? What is the cheapest project cost for that time? 5.0 Calculate the shortest delivery time for the project. What is the cheapest cost for that time
