La localización de instalaciones, como parte del diseño de una cadena de suministro, es considerada una decisión de naturaleza estratégica, de compromiso de recursos en el largo plazo y generalmente poco flexible. Es un factor externo que afecta la competitividad de la agricultura a niveles meso y micro, que impacta significativamente sobre los cos...
Positive linear programs (LPs), or equivalently, mixed packing and covering LPs, are LPs formulated with non-negative coefficients, constants, and variables. Notable special cases of positive LPs include packing LPs and covering LPs. Positive LPs model a wide range of fundamental problems both in theory of computation as well as in practice, thus h...
ABSTRACT This paper deals with a problem that Information Technology outsourcing suppliers generally face when selecting a working team technically capable for specific roles in software development projects. A combination of methodologies, interactively integrated, is proposed. They are Soft System Methodology to structure the problem, Repertory G...

This report presents an approach on how to utilize information on future states of traffic lights to reduce the energy consumption and trip time for a Heavy Duty Vehicle. Model Predictive Control is proposed as a solution to handle the optimisation on-line and the concept is tested for various prediction horizons in which information can be receive...
Given a connected graph G, a vertex v of G is said to be a branch vertex if its degree is strictly greater than 2. The Minimum Branch Vertices Spanning Tree problem (MBVST) consists in finding a spanning tree of G with the minimum number of branch vertices. This problem has been well studied in the literature and has applications specially for rout...

The issue of operative data reception on location and movement of railcars is significant the constantly growing requirements of the provision of timely and safe transportation. The technical solution for efficiency improvement of data collection on rail rolling stock is the implementation of an identification system. Nowadays, there are several su...
Hypergraphs are widely used for modeling and representing relationships between entities, one such field where their application is prolific is in bioinformatics. In the present era of big data, sizes and complexity of these hypergraphs grow exponentially, it is impossible to process them manually or even visualize their interconnectivity superfici...

Computational vision, visual computing and biomedical image analysis have made tremendous progress over the past two decades. This is mostly due the development of efficient learning and inference algorithms which allow better and richer modeling of image and visual understanding tasks. Hyper-graph representations are among the most prominent tools...
Pig Latin is a popular language which is widely used for parallel processing of massive data sets. Currently, subexpres-sions occurring repeatedly in Pig Latin scripts are executed as many times as they appear, and the current Pig Latin optimizer does not identify reuse opportunities. We present a novel optimization approach aiming at identifying a...
