A computerized delivery service provision method, that includes providing vehicles with bays, then selecting vehicles for assignment to a resource. The selecting of a vehicle to a resource includes determining resource candidate vehicles from among the vehicles that meet a vehicle candidacy criterion, then calculating hypothetical path routes, each including a path bay and a delivery bay that are associated with the candidate vehicles, thereby obtaining hypothetical path routes for the candidate vehicles. Then, determining a best path route from among the hypothetical path routes and selecting a vehicle from the candidate vehicles that is associated with the best path route, wherein the selected vehicle will pass through the path bay terminating at the delivery bay of the best path route, for provisioning of the delivery service between the selected vehicle and the resource, and wherein the best path route involves calculated starvation time, associated with the resource, which, compared to starvation times of any other hypothetical path routes associated with the resource, meets a starvation criterion.
