Abstract: This paper considers appointment scheduling for outpatient services when the service of scheduled patients can be interrupted by emergency arrivals. We consider a single doctor who consults K patients during a fixed-length session. Each patient has been given an appointment time during the session in advance. Our evaluation approach aims at obtaining accurate predictions at a very low computational cost for the waiting times of the patients and the idle time of the doctor. To this end, we investigate a modified Lindley recursion in a discrete-time framework. We assume general, possibly distinct, distributions for the patient's consultation times and allow for individual no-show probabilities. This fast evaluation method is then used in a local search algorithm to provide insights into scheduling with service interruptions. Numerical examples show that this method outperforms simulation optimization and naive approaches in terms of cost and running time.
