Highlights Motivate the need for equity when determining school bell times and school bus route schedules. Propose minimax and lexicographic minimax models for equity in regard to school start time changes. Perform numerical studies to compare equity-centered and efficiency-centered models. Assess solution quality and computational tractability of models.
Abstract We consider the school bus scheduling problem (SBSP) which simultaneously determines school bell times and route schedules. Often, the goal of the SBSP is to minimize the number of buses required by a school district. We extend a time-indexed integer programming model to incorporate additional considerations related to equity and efficiency. We seek to equitably reduce the disutilities associated with changing school start times via a minimax model, then propose a lexicographic minimax approach to improve minimax solutions. We apply our models to randomized instances based on a moderately-sized public school district to show the impact of incorporating equity.
