•
o From the above project, what is the probability that the project will be completed in 50 minutes?
o How many minutes will it take for the project be completed if the company projects 90% upper bound on the completion time of the project.
•
o University project that is analyzed by PERT has 42 activities, 13 of which are on the critical path. If the estimated time along the critical path is 105 days with a project variance of 25, what is the probability that the project will be completed in 95 days or more?
o If the University project still on a PERT network has these time estimates: optimistic = 2, most likely = 3, and pessimistic = 10. Calculate both theexpected activity time and variance?
• Kenny's activity that is on a PERT network has the following time estimates: optimistic = 3, most likely = 5, and pessimistic = 10. Also, the activity has a normal duration of 13 days but can be shortened to 11 days for an added cost of $1,500.
Given the analysis above:
o What is its expected activity time?
o What is the variance?
o What is the crash cost per period?
• AWOSCB'S project has an estimated time of 120 days on a critical pathhas a variance of 100 with a 20% chance of completion. How many days would you estimate this project to be completed. Note: round your estimation to the nearest day).
