Abstract:

This paper studies approximations to the average length of Vehicle Routing Problems (VRP). The approximations are valuable for strategic and ; planning analysis of transportation and logistics problems. The research focus is on VRP with varying number of customers, demands, and ; locations. This modeling environment can be used in transport and logistics models that deal with a distribution center serving an area with daily ; variations in the demand. The routes are calculated daily based on what freight is available. New approximations and experimental settings are ; introduced. Average distance travelled is estimated as a function of the number of customers served and the number of routes needed. ; Approximations are tested in instances with different customer spatial distributions, demand levels, number of customers, and time windows, ; Regression results indicate that the proposed approximations can reasonably predict the average length of VRP problems in randomly generated ; problems and real urban networks.
