Integrated Location-Routing-Scheduling for Multi-Trip Mobile Parcel Lockers with Time Windows (Short Paper)

Abstract
Mobile parcel lockers can reposition delivery capacity during the day, but this flexibility requires decisions that are tightly linked: where lockers stop, which customers are assigned to each stop, how lockers move, and when service takes place. We introduce the multi-trip mobile parcel locker problem with time windows (MT-MPLP-TW), which integrates locker deployment, customer assignment, parking selection, routing, scheduling, parking capacity, walking limits, and depot replenishment. We present a compact mixed-integer programming formulation and a logic-based Benders decomposition (LBBD) that separates route-and-assignment decisions from detailed time-expanded certification. Computational results on generated instances and on the single-trip mobile parcel locker benchmark show that the compact formulation is effective on small and medium instances, while LBBD gives stronger performance on larger and more constrained cases.
