• Construct a table showing earliest start and finish, latest start and finish, cost slope, and the two types of floats.
• What is the critical path of this project? What will the project cost?

Construct a table showing earliest start and finish, latest start and finish, cost slope, and the two types of floats. What is the critical path of this project? What will the project cost? What is the shortest possible time in which the project can be completed? What will the critical elements be in this case? Derive minimum cost schedules for all davs between the all-normal and the all-crash schedules
