Pickup 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...
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 کاملSTOCHASTIC 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 کاملA particle swarm optimization method for periodic vehicle routing problem with pickup and delivery in transportation
In this article, multiple-product PVRP with pickup and delivery that is used widely in goods distribution or other service companies, especially by railways, was introduced. A mathematical formulation was provided for this problem. Each product had a set of vehicles which could carry the product and pickup and delivery could simultaneously occur. To solve the problem, two meta-heuristic methods...
