use the Vertex42 worksheets to find a normal project schedule and an expedited project schedule to complete the project in 15 days (use OpenSolver1 if Solver fails). Verify that the extra cost of crashing the project to 15 days is 2250 instead of 2600. Also, what would be the shortest project duration if the crash budget was restricted to 1850 instead of 2250? In all cases, present the results in tabular form and identify all critical paths. Discuss the practicality of the solution.
