Abstract

This note introduces a refinement to a previously proposed tabu search algorithm for vehicle routing problems with time windows. This refinement yields new best known solutions on a set of benchmark instances of the multi-depot, the periodic and the site-dependent vehicle routing problems with time windows.

Keywords:

tabu search, multi-depot, periodic, site-dependent vehicle routing, time windows
