Vehicle Routing for City Logistics

In vehicle routing problems, side constraints are introduced to limit the number of ver- tices that can be visited with a single tour, thus leading to solutions that cover all

The objectives are to minimize the total routing cost (proportional to travel time) and customer waiting, and to balance the daily workload over the planning horizon.. Each

More precisely, we report, for each instance, name, number of customers, number of satellites, value of the initial solution (FC), and of the solution obtained by the local search

For all instances but five from instance set 4, the average solution quality of the ALNS is better than the quality of the best solutions found in the literature and for those

This hierarchical objective function, called Solomon’s objective in the sequel, is unusual in vehicle routing: for instance, most articles on the VRP minimize the total distance

Let g tj = 1 or 0 depending on whether customer x t is an element of S, or not respectively, and let C (Sj ) be the cost of the TSP solution through the set of customers in

In this paper we address the Multi Trip Vehicle Routing Problem with Time Windows and Release Dates (MTVRPTWR).. It is noteworthy that the problem is deterministic even if

Feasible solutions to the MP-E-VRP satisfy the following conditions: 1) each node i ∈ I is visited by a single EV in period p i , 2) each route starts and ends at the depot, 3) each
