Question

If the contracted duration for a project with the following network is 120 days, what is the probability (in percent) of meeting the schedule based on PERT analysis? Then, assume that the owner delays the start by 5 days while keeping the end date as originally scheduled. What is the probability (in percent) that the project will still finish at the originally scheduled completion date? The requested probabilities should be determined based on the entire network and not just one path.

Please assume that the provided pessimistic and optimistic values in the problem are based on 99 percentile level. Please show work for at least one instance of each calculation, that is, show work for:

  • one set of calculation of the mean, standard deviation and variance at activity level
  • one set of calculation of the mean, standard deviation and variance at the path level
  • calculation of probability

The network does not need to be reproduced in the submission.
