Towards a simulation based methodology for scheduling patient and providers at outpatient clinics

In this paper we develop a simulation based methodology for planning the schedules of providers and the appointment for patients. The methodology combines discrete-event simulation and optimization. Two types of patients are considered in this study: new and existing. In addition patient no-shows and walk-ins are also considered. The simulation model is used to find the best balance between new and existing patients arriving to each appointment time period during the day. New patients require more time to complete their admission processes and for visiting with a doctor. We report on computational results based on a real clinic, historical data, and both patient and management performance measures.
