1.0 Consider the project shown above without considering the assigned resources. Max Crash time indicates the most number of days that can be crashed.
a) Draw the network diagram and find the critical path, time and cost for an all-normal level of project activity.
b) Calculate the crash cost-per-day assuming that all activities may be partially crashed.
c) Which tasks should be crashed to do the project in 13 days? What is the project cost? What is the critical path now?
d) Calculate the shortest delivery time for the project. What is the cost?
2.0 Looking at the project from part 1a (using normal times), assume all tasks require design engineers (and assume that any that you have will be able to do the job in the time allotted). You as the project manager know that due to other projects, you will only have 2 design engineers at any given time for the duration of the project. How long will it take to complete the project now? Draw the resource load chart.
