Two-dimensional Pickup and Delivery Routing Problem with Loading Constraints

چکیده
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 based on a scheduling approach is developed. It is also shown that the nonoverlapping rectangle constraint can be extended to handle a practical constraint called sequential loading constraint .

In this paper, the fuzzy multi-depot vehicle routing problem with simultaneous pickup and delivery (FMDVRP-SPD) is investigated. The FMDVRP-SPD is the problem of allocating customers to several depots, so that the optimal set of routes is determined simultaneously to serve the pickup and the delivery demands of each customer within scattered depots. In the problem, both pickup and delivery dema...

Location-Routing Problem (LRP) emerges as one of the hybrid optimization problems in distribution networks in which, total cost of the system would be reduced significantly by simultaneous optimization of locating a set of facilities among candidate locations and routing vehicles. In this paper, a mixed integer linear programming model is presented for a two-echelon location-routing problem wit...
