Network Analysis 3. Given the following network diagram for a project (activity times are in days): 15 - 9 6 17 8 6 13 5 12 a) Determine Earliest Start time (ES), Earliest Finish time (EF), Latest Start time (LS), Latest Finish time (LF), and Slack Time for each activity. ES EF LS LF Slack Activity 1-2 1-3 1-4 2-5 2-6 3-7 4-7 5-8 6-8 7-8 Network Analysis b) Develop an optimal time-cost solution for reducing the project to an expected duration of 45 weeks. For each crash, list all available options for that crash, Indicate which activities should be crashed, and cost of each crash. Summarize and show the total cost of crashing. (NOTE: You can only crash 1 week at a time.) Options Crash 1 Paths Original time After Crash 1 Options Crash 2 Network Analysis 3.
