In spite of the success of theoretical appointment scheduling methods, there have been significant failures in practice primarily due to the rapid increase in the number of no-shows and cancelations from the individuals in recent times. These disruptions not only cause inconvenience to the management but also has a significant impact on the revenue, cost and resource utilization. In this research, we develop a hybrid probabilistic model based on logistic regression and Bayesian inference to predict the probability of no-shows in real-time. We also develop two novel non-sequential and sequential optimization models which can effectively use no-show probabilities for scheduling patients. Our integrated prediction and optimization model can be used to enable a precise overbooking strategy to reduce the negative effect of no-shows and fill appointment slots while maintaining short wait times. Using both simulated and real-world data, we demonstrate the effectiveness of the proposed hybrid predictive model and scheduling strategy compared to some of the well-studied approaches available in the literature.
