I uploaded a file, please help me answer those questions.
Read the case “The campus wedding (A)” (uploaded on Canvas) and answer the following questions:
Complete the network diagram template based on the campus wedding activity table (5 points).
Identify critical path(s), and the shortest time to complete the project before crashing any activities (5 points).
Crash activities so that the wedding can be held on Apr. 22. There may be more than one way to crash activities. You do not need to identify the one with minimal cost. But if you do, it will be easy for you to answer the next question (Hint: 3 of the 7 paths will be critical eventually and 2 of those critical paths will need to be crashed to meet the April 22 date) (10 points).
Find out a minimal cost plan that meets the April 22 wedding date. Calculate the minimal cost required to crash activities (Hint, you need to find a plan within minimal crash costs) (5 points).
Assumptions:
Today is March 31 and we can start tomorrow April 1 (i.e., project duration=22 days)
Everyone works 7 days a week
