- Determine completion time for the project?
- The restaurant is expected to lose $3,500 per week for every week the restaurant is not completed. Given the expediting costs, the manager thinks that it may be worthwhile reducing the duration of the project. By how many weeks should the project completion time be reduced, if the restaurant chain is willing to pay crashing/expediting cost?
- What is the project duration if all activities are crashed to their minimum?
