Solution of a Min-Max Vehicle Routing Problem
نویسندگان
چکیده
We use a branch-and-cut search to solve the Whizzkids’96 vehicle routing problem, demonstrating that the winning solution in the 1996 competition is in fact optimal. Our algorithmic framework combines the LP-based traveling salesman code of Applegate, Bixby, Chvátal, and Cook, with specialized cutting planes and a distributed search algorithm, permitting the use of a computing network located across Rice, Princeton, AT&T, and Bonn. The 1996 problem instance was developed by E. Aarts and J. K. Lenstra, and the competition was sponsored by the information technology firm CMG and the newspaper De Telegraaf.

An Improved Particle Swarm Optimization for a Class of Capacitated Vehicle Routing Problems
Vehicle Routing Problem (VRP) is addressed to a class of problems for determining a set of vehicle routes, in which each vehicle departs from a given depot, serves a given set of customers, and returns back to the same depot. On the other hand, simultaneous delivery and pickup problems have drawn much attention in the past few years due to its high usage in real world cases. This study, therefo...

متن کاملA Robust Approach to the Capacitated Vehicle Routing Problem with Uncertain Travel Times∗
We investigate a robust approach for solving the capacitated vehicle routing problem (CVRP) with uncertain travel times. It is based on the concept of K-adaptability, which allows to calculate a set of k feasible solutions in a preprocessing phase. Once a scenario occurs, the corresponding best solution may be picked out of the set of candidates. The aim is to determine the k candidates such th...
