Abstract : Predictions based on historical information increasingly inform priority-based admission decisions in capacity-constrained systems. However, better predictive accuracy does not necessarily lead to better admission decisions when individuals have heterogeneous resource-use durations and service outcomes. In this paper, we study how prediction errors affect decision quality in high-stakes settings where offline data is available and online exploration is infeasible. We do this in the context of a multiclass service system in which individuals’ classes are unobservable at admission and must be predicted from observed covariates. We first show that a priority score policy solves both the ground-truth and estimated admission control problems. We then develop an evaluation metric, Score@K ̂, for prediction-model selection that accounts for the endogenous admission boundary and operational cost consequences of prediction errors. We also develop a ranking-based uncertainty-quantification framework that exploits the priority structure to assess individual decision confidence. Finally, using data from incarceration-diversion programs in seven Illinois counties, we construct a simulation testbed environment to (1) show how our Score@K ̂ metric can help with prediction model selection in a realistic setting, and (2) demonstrate the impact of capacity on individual decision confidence.
