The Farmer’s American Bank of Leesburg is planning to install a new computerized accounts system. Bank management has determined the activities required to complete the project, the precedence relationships of the activities, and activity time estimates, as shown in the following table: Determine the expected project completion time and variance and determine the probability that the project will be completed in 40 weeks or less.
A group of developers is building a new shopping center. A consultant for the developers has constructed the following project network and assigned activity times, in weeks. Determine the earliest and latest activity times, activity slack, critical path, and duration for the project.
A new motorway project is being planned in Ireland, with its construction expected to cost €1
billion. The 100km route will connect Ireland's second largest city, Cork, with the city of
Limerick. The intended alignment for the motorway runs alongside the existing N20, which
runs through Blarney, Mallow and Charleville. The new motorway forms part of the Project
Ireland 2040 programme of infrastructure works.
The first step in the project is to appoint a project manager and develop a project team. Once
the team is selected and the staff is in place, the next task is to select a primary contractor to
manage and oversee the construction. The following activities, their immediate predecessors,
as well as the activity time estimates (in days) are standard for the planning and scheduling of
this project:

OSHA gave the mill only 35 weeks to make the changes; if the changes were not made by then, the mill would be fined $300,000.
