Abstract: | In physical distribution the location of depots and vehicle routes are interdependent problems, but they are usually treated
independently. Location-routing is the study of solving locational problems such that routing considerations are taken into
account. We present an iterative heuristic for the location-routing problem on the plane. For each depot the Weber problem
is solved using the end-points of the routes found previously as input nodes to the Weiszfeld procedure. Although the improvements
found are usually small they show that it pays not to ignore the routing aspects when solving continuous location problems.
Possible research avenues in continuous location-routing will also be suggested. |
