Failure mode prediction and energy forecasting of PV plants to assist dynamic maintenance tasks by ANN based models
(Elsevier, 2015-09)
In the field of renewable energy, reliability analysis techniques combining the operating time of the system with the observation of operational and environmental conditions, are gaining importance over time. In this ...

On insertion tie-breaking rules in heuristics for the permutation flowshop scheduling problem
(Elsevier, 2014-05)
The most efficient approximate procedures so far for the flowshop scheduling problem with makespan objective – i.e. the NEH heuristic and the iterated greedy algorithm – are based on constructing a sequence by iteratively ...

A decision-making model to design a sustainable container depot logistic network: the case of the port of Valencia
(Vilnius Gediminas Technical University Press, 2018)
In this paper, the design of a maritime container depot logistic network in a hinterland is studied. Containers are a basic tool in multimodal product transportation and all related operations have an impact on the ...

Diseño y aplicación de una herramienta para la optimización de rutas de vehículos con aspectos medioambientales
(2016-07-18)
En la actualidad, en torno al 90% de la población de la Unión Europea se encuentra expuesta a altas concentraciones de algunos de los contaminantes atmosféricos más nocivos para la salud, reduciendo la esperanza de vida ...

Setting a common due date in a constrained flowshop: A variable neighbourhood search approach
(2010)
In this paper we study a due date setting problem in a flowshop layout. The problem consists of scheduling a set of jobs arriving to the system together with jobs already present (denoted as old jobs), in order to set a ...

Increasing Sustainability of Logistic Networks by Reducing Product Losses: A Network DEA Approach
(Hindawi Limited, 2018)
This paper considers a multiproduct supply network, in which losses (e.g., spoilage of perishable products) can occur at either the nodes or the arcs. Using observed data, a Network Data Envelopment Analysis (NDEA) approach ...

A beam-search-based constructive heuristic for the PFSP to minimise total flowtime
(Elsevier, 2017)
In this paper we present a beam-search-based constructive heuristic to solve the permutation flowshop scheduling problem with total flowtime minimisation as objective. This well-known problem is NP-hard, and several ...

Estimación no paramétrica de la fiabilidad de un transformador con eventos recurrentes
(2012)
El objetivo del trabajo desarrollado es la estimación de la función de fiabilidad de un transformador de potencia de una subestación eléctrica de media tensión. Para ello se ha realizado una estimación no paramétrica ...

Serial vs. divergent supply chain networks: a comparative analysis of the bullwhip effect
(Taylor & Francis, 2014)
The amplification of demand variation in a supply chain network (SCN) is a well-known phenomenon called the bullwhip effect, which creates inefficiencies due to high variation in the order quantities placed between companies, ...
