[EN] Many supply chains are composed of producers, suppliers, carriers, and customers. These agents must be coordinated to reduce waste and lead times. Production and distribution are two essential phases in most supply ...
[EN] This paper analyzes a stochastic version of the vehicle routing problem in which customers' demands are not only stochastic but also correlated. In order to solve this stochastic and correlated optimization problem, ...

[EN] The increasing use of electric vehicles in road and air transportation, especially in last-mile delivery and city mobility, raises new operational challenges due to the limited capacity of electric batteries. These ...
This paper discusses horizontal cooperation in road transportation and supports the relevance of this praxis as a way of reducing delivery costs and greenhouse gas emissions. In a competitive market, costs reduction due ...
Horizontal cooperation in logistics refers to how two or more companies can cooperate in order to achieve a common objective, which is usually related to minimization of global distribution costs. This paper discusses ...

[EN] In this Thesis, we analyze an industry type that has two basic features: Its products are distributed in a geographic level and it reuses material after that is consumed to made new products. Because of these features, ...
[EN] Many real-life applications of the vehicle routing problem (VRP) occur in scenarios subject to uncertainty or dynamic conditions. Thus, for instance, traveling times or customers' demands might be better modeled as ...

[EN] The well-known Vehicle Routing Problem (VRP) is to find proper sequence of routes in order to minimize transportation costs. In this paper, a mixed-integer programming model is presented for a food distributer company ...
The Vehicle Routing Problem (VRP) has been thoroughly studied in the last decades. However, the main focus has been on the deterministic version where customer demands are fixed and known in advance.
Uncertainty in demand ...
