Today's automotive factories are essentially assembly plants that receive parts from a vast network of suppliers around the world. Transporting thousands of part types over very long distances is a major logistic problem whose solution is a critical factor in the factory management. In this study we have developed a statistical and optimization met...

This paper considers a multi-container loading problem in which each customer orders a set of pallets of different weights and the objective is to meet all orders with the minimum number of trucks. Strict constraints regarding stability, multidrop, and axle weight limits must be respected for each truck at each stop along the route. When assigning...

This paper addresses an integrated routing and loading problem in which the pallets ordered by a set of customers have to be delivered by a set of trucks so that the total distance traveled is minimized. The problem has two main distinctive features. On the one hand, when assigning pallets to trucks, strict packing constraints, concerning axle weig...

In a setting that prioritises the achievement of Sustainable Development Goals (SDG), sustainable development cannot be achieved without the contribution of female talent. This paper is focused on studying the reasons for the gender gap and the offered strategies to reduce it. The debate on the reasons for the low enrolment rates of girls in techno...

Container loading problems (CLP), in which a set of boxes have to be loaded into containers or onto trucks, are at the core of many transportation problems. Good solutions to these packing problems are crucial for the efficient use of logistic resources. However, to produce solutions that are useful in practice, besides the basic conditions ensurin...

The glass cutting problem proposed by Saint Gobain for the 2018 ROADEF challenge includes some specific constraints that prevent the direct application of procedures developed for the standard cutting problem. On the one hand, the sheets to be cut have defects that make them unique and they must be used in a given order. On the other hand, pieces a...

We consider the multicontainer loading problem of a company that has to serve its customers by first putting the products on pallets and then loading pallets onto trucks. When a large number of units of a product have to be shipped, the company requires that homogeneous pallets, with only one product, are built first, then weakly heterogeneous pall...

We address the multi container loading problem of a company that serves its customers’ orders by building pallets with the required products and loading them into trucks. The problem is solved by using integer linear models. To be useful in practice, our models consider three types of constraints: geometric constraints, so that pallets lie complete...

La baja presencia de mujeres en carreras de ingeniería en general, y en informática en particular, ha sido reconocida por diferentes estudios internacionales. Esto está ocasionando un sesgo tanto en la industria como en la universidad hacia una visión única de la Informática, perdiendo la riqueza que ofrece siempre la diversidad. Así, nuestro centr...

Renault, a large car manufacturer with factories all over the world, has a production system in which not every factory produces all the parts required to assemble a vehicle. Every day, large quantities of car parts are sent from one factory to another, defining very large truck/container transportation problems. The main challenge faced by the Ren...

This paper deals with the problem of a logistics company that has to serve its customers by first putting the products on pallets and then loading the pallets into trucks. Besides the standard geometric constraints of products not overlapping each other and not exceeding the dimensions of pallets and trucks, in this real problem, there are many oth...

This paper deals with the problem of a distribution company that has to serve its customers by putting first the products on pallets and then loading the pallets onto trucks. We approach the problem by developing and solving integer linear models. We start with basic models, that include the essential features of the problem, such as respecting the...

A distribution company has to send products, packed into shippers, from the warehouse to retail shops. The number of different shipper types is regarded as a parameter given by the user, who is looking for a balance between transportation costs and stock and procurement costs. The problem is to decide the sizes of the shipper types to keep at the w...

The container loading problem consists in packing a set of boxes of different dimensions into a large container of fixed dimensions, usually with the objective of maximising the container load. In practical problems, besides the geometric constraints of not exceeding the container dimensions and ensuring the non-overlapping of boxes, other requirem...
