Time-Dependent Traveling Salesman Problem with Multiple Time Windows

The TSP, VRP and OP problems with time constraints have one common sub-problem – the task of finding the minimum route duration for a given order of customers. While much work has been done on routing and scheduling problems with time windows, to this date only few articles considered problems with multiple time windows. Moreover, since the assumption of constant travel time between two locatio...

Algorithms for the On-Line Quota Traveling Salesman Problem

The Quota Traveling Salesman Problem is a generalization of the well known Traveling Salesman Problem. The goal of the traveling salesman is, in this case, to reach a given quota of the sales, minimizing the amount of time. In this paper we address the on-line version of the problem, where requests are given over time. We present algorithms for various metric spaces, and analyze their performan...

An extended multiple Traveling Salesman Problem

This paper deals with the routing problem of health care sta in a home health care problem. Given a list of patients needing several cares, the problem is to assign cares to care workers. Some cares have to be performed by several persons and some cares cannot be performed with others. If a patient needs several cares, he may want to be treated by the same person. Moreover, some skills constrai...

The Uncapacitated Asymmetric Traveling Salesman Problem with Multiple Stacks

In the uncapacitated asymmetric traveling salesman with multiple stacks, we perform a hamiltonian circuit to pick up n items, storing them in a vehicle with k stacks satisfying last-in-first-out constraints, and then we deliver every item by performing a hamiltonian circuit. We are interested in the convex hull of the (arc-)incidence vectors of such couples of hamiltonian circuits. For the gene...
