PROGRAM THIS USING CPLEX (PLEASE POST THE CODE OR A PHOTO OF THE CODE) Greydog Bus Company operates buses between Boston and Washington, D.C. A bus trip between these two cities takes 6 hours. Federal law requires that a driver rest for four or more hours between trips. A drivers workday consists of two trips: one from Boston to Washington and one from Washington to Boston. Table 54 gives the departure times for the buses. Greydogs goal is to minimize the total downtime for all drivers. How should Greydog assign crews to trips? Note: It is permissible for a drivers day to overlap midnight. For example, a Washington-based driver can be assigned to the WashingtonBoston 3 P.M. trip and the BostonWashington 6 A.M. trip.
