Problem 1: Use the work breakdown structure (WBS) and activity duration data to do the following:

  • On a separate sheet, create an activity on node (AON) diagram for this project. Draw it neatly. Identify the critical path.
  • Calculate the Expected Time (TE) for each activity. All times are in weeks. Round off your answers for TE to two decimal places.
  • Using the TE time, solve for the early start, early finish, late start, late finish, and slack time for each activity. Show your answers on the diagram.
  • Calculate the weekly crash costs.
  • Use the normal probability density function to estimate the probability that the project will be completed within 1 week of its scheduled completion time and to estimate a 90% Confidence interval for the project completion time.
