Mueller & Associates is a urban planning firm that is designing a new public park in an Omaha suburb. Coordination of the architect and subcontractors will require a major effort to meet the 45-week completion date requested by the owner. The Mueller project manager prepared the following project network. A project network with 10 activities and 14 directed arcs is shown. Activity Start is connected to activity A. Activity A is connected to activity B, to activity C, and to activity D. Activity B is connected to activity F. Activity C is connected to activity E and to activity F. Activity D is connected to activity E. Activity E is connected to activity G and to activity Finish. Activity F is connected to activity G and to activity H. Activity G is connected to activity H. Activity H is connected to activity Finish. Activity Finish has no arcs directed to other activities. Estimates of the optimistic, most probable, and pessimistic times (in weeks) for the activities are as follows.

(b) What is the expected project completion time (in weeks)? (c) Based only on the critical path, what is the estimated probability the project can be completed in 45 weeks as requested by the owner? (Round your answer to four decimal places.) (d) Based only on the critical path, what is the estimated probability the building project could run more than 3 months late? Use 58 weeks for this calculation. (Round your answer to four decimal places.) (e) What should the construction company tell the owner? (Enter your free-form answer using as many characters as necessary.)
Critical Path Method
The critical path is the longest succession of tasks that has to be successfully completed to conclude a project entirely. The tasks involved in the sequence are called critical activities, as any task getting delayed will result in the whole project getting delayed. To determine the time duration of a project, the critical path has to be identified. The critical path method or CPM is used by project managers to evaluate the least amount of time required to finish each task with the least amount of delay.
Cost Analysis
The entire idea of cost of production or definition of production cost is applied corresponding or we can say that it is related to investment or money cost.
