A Branch-and-price Method for the Vehicle Routing problem with Cross-docking and Time Windows
(Universidade Federal de Santa Catarina, 2013-10)
One important factor in supply chain management is to efficiently control the supply chain flows. Due to its importance, many companies are trying to develop efficient methods to increase customer satisfaction and reduce ...
A Sweep-Heuristic Based Formulation for the Vehicle Routing Problem with Cross Docking
(Elsevier, 2013-01)
Cross-docking is a warehousing strategy in logistics used by process industries manufacturing products with high proportions of distribution costs. It is described as the process of moving goods from suppliers to customers ...
Heuristic Approaches for the Robust Vehicle Routing Problem
(Combinatorial Optimization, 2014-07-22)
In this article, the Robust Vehicle Routing Problem (RVRP) with uncertain traveling costs is studied. It covers a number of important applications in urban transportation and large scale bio-terrorism emergency. The uncertain ...
Cooperation strategies featuring optimization in the school transportation system in BogotaEstrategias de cooperación en el sistema de transporte de estudiantes en Bogotá usando optimización
(DYNA, 2017)
The transport of students presents important challenges in the case of the city of Bogota, where an important cluster of schools is located in one zone, but there is only one road connecting these schools to residential ...
The Maximin HAZMAT Routing Problem
(2015)
The hazardous material routing problem from an origin to a destination in an urban area is addressed. We maximise the distance between the route and its closest vulnerable centre, weighted by the centre’s population. A ...
The maxisum and maximin-maxisum HAZMAT routing problems
(2016)
We design routes for transportation of hazardous materials (HAZMAT) in urban areas, with multiple origin-destination pairs. First, we introduce the maxisum HAZMAT routing problem, which maximizes the sum of the population-weighted ...
Model of routing for raw milk collection using genetic algorithms
(Sistemas & Telemática, 2014-12)
The article examines the use of a metaheuristic method – genetic algorithms – for evaluating a model of routes for raw milk collection. A model was implemented based on real data, collected through fieldwork, following the ...
An integer programming approach to a real-world recyclable waste collection problem in Argentina
(SAGE Publications, 2017-05)
This article reports on the use of mathematical programming techniques to optimise the routes of a recyclable waste collection system servicing Morón, a large municipality outside Buenos Aires, Argentina. The truck routing ...
Equation of state for five-dimensional hyperspheres from the chemical-potential route
(American Physical Society, 2015-08)
We use the Percus-Yevick approach in the chemical-potential route to evaluate the equation of state of hard hyperspheres in five dimensions. The evaluation requires the derivation of an analytical expression for the contact ...
