Seminario 23/13 – Christian Blum (Artificial Intelligence Research Institute, IIIA-CSIC): Recent Developments in Hybrid Metaheuristics for Combinatorial Optimization

Publicado el
Haz un comentario

A lot of research has been dedicated to solving combinatorial optimization problems during past decades, both in the Operations Research field and in Artificial Intelligence. As a result, researchers and/or practitioners are able to choose between a wide range of both exact and approximate techniques when faced with an optimization problem of that type. Nevertheless,…

Seminario 23/12 – José Manuel Cordero (Universidad de Extremadura): La consideración del contexto al analizar cambios en la productividad con modelos no paramétricos

Publicado el
Haz un comentario

Las variables de contexto o ambientales suelen desempeñar un papel importante en la mayoría de los procesos productivos, condicionando en gran medida tanto la estimación de los niveles de eficiencia de las unidades evaluadas como posibles factores explicativos de las ineficiencias detectadas en la mayoría de los estudios empíricos. Sin embargo, cuando se analizan los…

Seminario 23/11 – Behzad Hezarkhani (Southampton Business School, University of Southampton): Global Agricultural Supply Chains under Tariff-Rate Quotas

Publicado el
Haz un comentario

The tariff rate quota (TRQ) is a common market access instrument in global agricultural trade that allows a predetermined quantity of a product to be imported at a lower tariff rate than the rate typically applied to that product. In this study, we examine the design and administration of TRQ systems from an operations management…

Abstract In an era when the decision-making process is often based on the analysis of complex and evolving data, it is crucial to have systems which allow us to incorporate human knowledge and provide valuable support to the decision maker. During this talk, statistical modelling and mathematical optimization paradigms merge to address the problems of,…

Seminario 23/09 – Miguel López Morell (Universidad de Murcia) y Bernardo Batiz-Lazo (Northumbria University) – Expanding and integrating Spanish banking networks and IT systems in Latin America

Publicado el

Abstract Topic: Revisit the extant literature on the growth of Spanish banks in Latin America through the analysis of the processes of IT integration. We explore the technological and management issues around the implementation of global platforms (developed by either third parties or at head office) which replaced, interfaced or co-existed with pre-existing local IT…

Seminario 23/08 – Santiago Sánchez Pagés (King’s College London) – Braggart or humble? The effect of self-reports on performance

Publicado el

An extensive literature has studied both in the field and in the lab the effects on performance of providing absolute and relative verifiable feedback, finding mixed results. Another branch of the literature has studied the effects of non-verifiable centrally-provided feedback, also with mixed results.  But, to the best of our knowledge, no study has explored…
