STOCHASTIC VEHICLE ROUTING PROBLEMS WITH SIMULTANEOUS PICKUP AND DELIVERY SERVICES
The problem of designing a set of routes with minimum cost to serve a collection of customers with a fleet of vehicles is a fundamental challenge when the number of customers to be dropped or picked up is not known during the planning horizon. The purpose of this paper is to develop a vehicle routing Problem (VRP) model that addresses stochastic simultaneous pickup and delivery in the urban pub...
متن کاملDynamic pickup and delivery problems
In the last decade, there has been an increasing body of research in dynamic vehicle routing problems. This article surveys the subclass of those problems called dynamic pickup and delivery problems, in which objects or people have to be collected and delivered in real time. It discusses some general issues as well as solution strategies.

متن کاملTwo-dimensional Pickup and Delivery Routing Problem with Loading Constraints
In this paper, a special case of the vehicle routing problem in which the demands consist in a set of rectangular two-dimensional weighted items is considered. The vehicles have a two-dimensional loading surface and a maximum weight capacity. These problems have a routing and a packing component. A framework to handle the loading of a vehicle is proposed. A Constraint Programming loading model ...
متن کاملPickup and Delivery Vehicle Routing with Multidimensional Loading Constraints
In this paper we introduce a new, pickup and delivery vehicle routing model where weight limits and also packing constraints are taken into account. In the model the vehicles have to transport 3-dimensional boxes from their pickup points into their delivery points. The boxes have weights and the vehicles has to satisfy a weight limit. We present a heuristic algorithm for the solution of the pro...
