Modeling of Multi-Level Planning of Shifting Bottleneck Resources Integrated with Downstream Wards in a Hospital

Planning and scheduling critical resources in hospitals is significant for better service profit generation. The current research investigates an integrated planning problem at different levels of operating rooms, intensive care units, wards. theory constraints applied to make plans schedules rooms based on the capacity room itself downstream A mixed integer linear programming model developed considering shifting bottleneck among room, unit, hospital wards maximize utilization all planning. Different sizes problems hospital, including small, medium, large sizes, are created with variable arrivals surgery durations solved using a CPLEX solver validating models. Later, application proposed models real world develop systems discussed, future extensions suggested.
