Pickup and delivery of partial loads with “soft” time windows. (English) Zbl 0633.90029

We apply Benders’ decomposition procedure to the single-vehicle routing and scheduling problem with time windows, partial loads, and dwell times. We provide a formula and demonstrate that the scheduling subproblem is the dual of a network flow problem. We describe an exact algorithm which exploits its structure, and construct a route improvement heuristic based on the master problem. A heuristic for building an initial route is also presented.
