A simple example in healthcare: Let consider 7 patients with different surgeries times: ST=[4h30, 4h, 3h, 3h, 2h30, 1h30, 1h] We have to decide how to assign patients to the operating rooms.Let consider 6 operating rooms availabie with their corresponding capacities OR=[7h30, 6h, 5h30, 5h30, 6h3o, 7h). We would like to assign all patients and use the minimum number of operating rooms (additional variable indicating if the room is used or not must be added). Propose a model and solve it using CPLEX
