In the crew-scheduling problem, suppose (as in the sensitivity analysis we discussed) that the first Chicago flight, C1, is delayed by 2 hours—that is, its departure and arrival times move up to 8 A.M. and 12 P.M., respectively. How does the model need to be modified? What is the new optimal solution? Is it the same as the solution indicated by SolverTable in Figure 5.35? If not, why not?
