Abstract: This paper introduces a class of cuts, called reachability cuts, for the Vehicle Routing

Problem with Time Windows (VRPTW). Reachability cuts are closely related to cuts derived

from precedence constraints in the Asymmetric Traveling Salesman Problem with Time

Windows and to k-path cuts for the VRPTW. In particular, any reachability cut dominates

one or more k-path cuts. The paper presents separation procedures for reachability cuts

and reports computational experiments on well-known VRPTW instances. The computational

results suggest that reachability cuts can be highly useful as cutting planes for certain

VRPTW instances.

Keywords: Routing; time windows; precedence constraints
