Ítem Autopercepción de la competencia digital del alumnado del grado en Educación Social con Ikanos(Campus Virtuales, 2022-01-31) Paños Castro, Jessica ; Bilbao Aiastui, Eider ; Arruti, Arantza ; Carballedo Morillo, RobertoLa competencia digital es una competencia clave que implica el uso creativo, crítico y seguro de las TIC. Los/as profesionales de la Educación Social deben ir en esta línea para ser ciudadanos/as competentes en una sociedad digitalizada. Así, se recoge la necesidad de desarrollar esta competencia en el Libro blanco del título de Grado en Pedagogía y Educación Social. Este estudio tiene como objetivo analizar la autopercepción de la competencia digital del alumnado en el grado en Educación Social. Para ello, se utiliza el Test Ikanos. En el estudio, han participado 266 estudiantes de la Universidad de Deusto de tres cursos. Los resultados nos indican una autopercepción baja de la competencia digital. Los ítems con menor puntuación se corresponden con las competencias de innovación, seguridad de los datos personales y privacidad, y programación. Sin embargo, las competencias de almacenamiento y recuperación de la información, e interactuar son las puntuaciones medias más altas.Ítem The definition of a self-reflection tool named Aurora for the assessment of university professors´digital competence(Universidad de Barcelona, Digital Education Observatory (OED), 2023-12-29) Bilbao Aiastui, Eider ; Arruti, Arantza ; Carballedo Morillo, RobertoWe are currently facing a historical moment in which educational practices are being transformed using technology. In this scenario, higher education institutions have a great responsibility towards the Digital Competence of University Professor (DCUP). The main objective of the study is to contribute to the improvement of the self-reflection of the DCUP. Therefore, a self-assessment tool called Aurora, based on the European Framework for the Digital Competence of Educators (DigCompEdu) model, is defined. Subsequently, the tool is applied, and the results are analysed. The methodology used is quantitative by means of an online survey. The sample consisted of 154 university professors from the University of Deusto (UD). On the one hand, through descriptive analysis it is highlighted that the Aurora questionnaire is an objective tool to measure the self-reflection of the DCUP. On the other hand, through the inferential analysis it is underlined that significant differences are found in the demographic data of professional category and age. It is also stressed that there are significant differences in the correlations. These results show that it is necessary to create a questionnaire that measures all the competences of the DigCompEdu model to be considering the DigCompEdu model.Ítem Diseño de una heurística de construcción y nuevos operadores de mejora para la resolución de problemas de asignación de rutas a vehículos con restricción de ventanas de tiempo(Universidad de Deusto, 2016-01-20) Carballedo Morillo, Roberto; Díaz Martín, José Fernando; Facultad de Ingeniería; Ingeniería Informática y TelecomunicaciónEl transporte es un sector que juega un papel muy importante en la sociedad de hoy en día. La distribución de mercancías, el movimiento de personas, o la provisión de servicios como la recogida de residuos, son actividades que impactan directamente en la calidad de vida, pero que también tienen una considerable repercusión en la economía y el medio ambiente. En el ámbito científico, el transporte tiene una relevancia igualmente crucial puesto que en torno a esta área de aplicación han surgido un sinfín de problemas difíciles de resolver debido a su complejidad computacional. Esto provoca que en muchas ocasiones sea prácticamente imposible la obtención de soluciones factibles, siendo necesario el uso de técnicas de aproximación que permitan obtener una buena solución en un tiempo limitado. En este sentido, surgen un amplio abanico de problemas de optimización y técnicas de resolución que tienen como objetivo principal la mejora continua para la obtención de soluciones cada vez más precisas, y con costes computacionales permisibles. La presente tesis doctoral se enmarca en el área de los problemas de generación de rutas para vehículos. Estos tipos de problemas han sido ampliamente estudiados durante los últimos 50 años, y siguen siendo foco de interés científico hoy en día, ya que aún no existe una técnica capaz de resolver de manera adecuada algunas tipologías de problemas. Es por esta razón que es posible encontrar y abordar puntos de mejora que contribuyan a la optimización de los procesos de resolución existentes. Con todo lo anterior, el trabajo de tesis doctoral presentado en este documento focaliza sus esfuerzos en la mejora del proceso de resolución de una de las variantes más ampliamente estudiadas del problema básico de asignación de rutas a vehículos: la variante con ventanas de tiempo (VRPTW). En concreto, se abordará el desarrollo de algoritmos para dos de las fases del proceso de resolución: la construcción de la solución inicial y la mejora iterativa de soluciones. La principal novedad del enfoque propuesto se encuentra en la definición de operadores de mejora basados en la reducción del número de rutas (que es uno de los criterios utilizados para medir la calidad de una solución). Tras una extensa experimentación comparando los métodos propuestos con las técnicas más representativas, y un exhaustivo y riguroso análisis de los resultados obtenidos, puede concluirse que los algoritmos generados representan un complemento idóneo para ser integrado en cualquiera de las técnicas heurísticas o metaheurísticas que atesoran los mejores resultados para los juegos de ensayo referentes en el contexto del VRPTW.Ítem Fostering multi-stakeholder collaboration through co-production and rewarding(Springer Science and Business Media Deutschland GmbH, 2023) López de Ipiña González de Artaza, Diego ; Badiola Martínez, Julen; Lauzurica, Daniel; Silva Palacios, Daniel ; Carballedo Morillo, Roberto ; Casado Mansilla, Diego ; Not, Elena; Leonardi, Chiara ; Misikangas, PauliThis paper describes a digital tool to foster sustainable engagement of stakeholders in collaborative processes, namely Collaborative Environment. A distinguishing aspect of the tool is its co-production model-based project management and its emphasis on reusability. The paper also reasons on how this tool should be effectively complemented to realize long-run and effective stakeholder collaboration, which is essential in bringing about social innovation.Ítem Good practice proposal for the implementation, presentation, and comparison of metaheuristics for solving routing problems(Elsevier B.V., 2018-01-03) Osaba, Eneko ; Carballedo Morillo, Roberto ; Díaz Martín, José Fernando ; Onieva Caracuel, Enrique ; Masegosa Arredondo, Antonio David ; Perallos Ruiz, AsierResearchers who investigate in any area related to computational algorithms (both defining new algorithms or improving existing ones) usually find large difficulties to test their work. Comparisons among different researches in this field are often a hard task, due to the ambiguity or lack of detail in the presentation of the work and its results. On many occasions, the replication of the work conducted by other researchers is required, which leads to a waste of time and a delay in the research advances. The authors of this study propose a procedure to introduce new techniques and their results in the field of routing problems. In this paper, this procedure is detailed, and a set of good practices to follow are deeply described. It is noteworthy that this procedure can be applied to any combinatorial optimization problem. Anyway, the literature of this study is focused on routing problems. This field has been chosen because of its importance in real world, and its relevance in the actual literature.Ítem On efficiently solving the vehicle routing problem with time windows using the bat algorithm with random reinsertion operators(Springer Verlag, 2018) Osaba, Eneko ; Carballedo Morillo, Roberto; Yang, Xin-She; Fister, Iztok; López García, Pedro ; Ser Lorente, Javier delAn evolutionary and discrete variant of the Bat Algorithm (EDBA) is proposed for solving the Vehicle Routing Problem with Time Windows, or VRPTW. The EDBA developed not only presents an improved movement strategy, but it also combines with diverse heuristic operators to deal with this type of complex problems. One of the main new concepts is to unify the search process and the minimization of the routes and total distance in the same operators. This hybridization is achieved by using selective node extractions and subsequent reinsertions. In addition, the new approach analyzes all the routes that compose a solution with the intention of enhancing the diversification ability of the search process. In this study, several variants of the EDBA are shown and tested in order to measure the quality of both metaheuristic algorithms and their operators. The benchmark experiments have been carried out by using the 56 instances that compose the 100 customers Solomon’s benchmark. Two statistical tests have also been carried out so as to analyze the results and draw proper conclusions.Ítem Skills requirements for the European machine tool sector emerging from its digitalization(MDPI AG, 2020-12-13) Akyazi, Tugçe; Goti Elordi, Aitor; Oyarbide Zubillaga, Aitor; Alberdi Celaya, Elisabete; Carballedo Morillo, Roberto; Ibeas, Rafael; García Bringas, PabloThe machine tool industry, which is the starting point of all the metal producing activities, is presently undergoing rapid and continuous changes as a result of the fourth industrial revolution Industry 4.0. Manufacturing models are profoundly transforming with emerging digitalization. Smart technologies like artificial intelligence (AI), big data, the Internet of Things (IoT), digital twin, allow the machine tool companies to optimize processes, increase efficiency and reduce waste through a new phase of automation. These technologies, as well, enable the machine tool producers to reach the aim of creating products with improved performance, extended life, high reliability that are eco-efficient. Therefore, Industry 4.0 could be perceived as an invaluable opportunity for the machine tool sector, only if the sector has a competent workforce capable of handling the implementation of new business models and technological developments. The main condition to create this highly qualified workforce is reskilling and upskilling of the current workforce. Once we define the expected evolution of skills requirements, we can clarify the skills mismatch between the workers and job profiles. Only then, we can reduce them by delivering well-developed trainings. For this purpose, this article identifies the current and foreseen skills requirements demanded by the machine tool industry workforce. To this end, we generated an integrated database for the sector with the present and prospective skills needs of the metal processing sector professionals. The presented sectoral database is a fundamental structure that will make the sector acquire targeted industrial reforms. It can also be an essential instrument for machine tool companies, policymakers, academics and education or training centers to build well-designed and effective training programs to enhance the skills of the labor force.Ítem A systematic literature review about the level of digital competences defined by DigCompEdu in higher education(Instituto de Ciencias de la Educación, 2021-12) Bilbao Aiastui, Eider; Arruti, Arantza; Carballedo Morillo, RobertoNowadays, we are facing a historical moment in which education practices are being transformed—mainly due to the increase of technologies and their massive use at all levels of society; thus, it is necessary to integrate them in educational settings. In this context, the aim of this paper is to analyse the level of technological competences of university professors. To this end, a systematic literature review based on the PRISMA methodology is carried out. he search was focused on WoS and SCOPUS databases. Initially, 815 documents were retrieved, and after applying the exclusion criteria 30 papers were selected. The selected papers have been analysed in detail and the final conclusions have been structured according to the DigCompEdu digital competence framework. The results show that the level of Digital Competences of University Professors (DCUP) is moderate, and highlight aspects to improve: Reflective Practice is not cited in any article, and Learner ́s Empowerment and Facilitating Students’ Digital Competence are the least referred. These aspects should be considered for future research and, for this reason, it is recommended to carry out continuous training for university professors supported by the DigCompEdu framework.
