Resource allocation simulation on operating rooms of hospital

Operating room (OR) plays a key role in hospitals. Resources required for surgery process include both manpower and facilities. A rational utilization of resource may lead to high efficiency of OR, as well as patients satisfaction. A discrete event system simulation model of ORs in hospital is built under SIMIO. The case study is investigated based on current patients flow and operation data collected from a comprehensive hospital in Ningbo. By simulation, the current resources' utilization and the flow time of surgeries are analyzed. The simulation results indicate problems in current OR's management. Several suggestions based on resource allocation simulation are proposed for improving the OR's efficiency.
