Appointment Rule of CT Department under Emergency Random Demand: Based on Numerical Calculation

Abstract

Abstract. This work considers on the impact of different appointment rules on the expected direct waiting cost of patients, the service provider's expected idle cost and overtime cost under the random demand of emergency patients. We compute these costs by modeling and numerical calculation on MATLAB. Numerical examples show that allocating the reserved slots in the middle of the session could dramatically decrease the direct waiting cost of patients. For idle cost and overtime cost of service provider, reserving the slots in the end of the session performs best. Allocated the reserved slots in the end of the session performs well on the expected total cost.
