La decisión de afrontar un gran programa de adquisiciones para la defensa suele tener muy presente los costes que supone. Si bien en ocasiones tal decisión queda delimitada a la consideración de costes de adquisición, es menester entrar exhaustivamente en el resto de costes que supondrá el mantenimiento durante un determinado ciclo de vida de...

La presente tesis doctoral trata sobre un marco de gestión para la asistencia de las garantías en empresas que comercializan productos (bien estándar, bien personalizados), de manera que se facilite la organización y la toma de decisiones en el servicio postventa de la compañía. Para ello, este trabajo se basa en un marco estructurado en...

This research looks into a systemic impact factor (SIF) as a complement to enhance the prescriptive capabilities of electric substations with the objective of improving the reliability and robustness of components. As electrical networks become increasingly complex, prescriptive analytical tools are needed to ensure sustained power delivery....

Se propone una técnica para la priorización de activos físicos que se basa en la contribución que hace cada uno de ellos al rendimiento global (throughput). La técnica presentada está basada en la Eficiencia del Rendimiento Global del Sistema (Overall Throughput Effectiveness, OTE) y relaciona la disponibilidad de cada equipo con su utilización...

An asset's risk is a useful indicator for determining optimal time of repair/replacement for assets in order to yield minimal operational cost of maintenance. For a successful asset management practice, asset-intensive organisations must understand the risk profile associated with their asset portfolio and how this will change over time....

Este documento se centra en una de las etapas propuestas por los autores como marco de referencia para mejorar la gestión del servicio post-venta. Concretamente, la etapa referida trata de aplicar el análisis causa-raiz de fallos para la mejora de la organización de las asistencias en garantía. Dicho análisis permitetomar mejores decisiones...

This paper conducts a comprehensive review of the role of digitalization in railway maintenance management, particularly through the lens of the International Union of Railways (UIC) asset management framework. The study aims to assess how digital technologies such as Big Data, the Internet of Things (IoT), and Artificial Intelligence (AI)...

This study presents an innovative methodology to improve the maintenance of railway infrastructures, integrating degradation models and economic optimization. The combination of a degradation model and a semi-Markovian model supported by the Weibull function, calculates the economically optimal degradation, to release the preventive...

This contribution illustrates the advantages of measures and indicators based on the notions of Shannon entropy which is widely implemented in thermodynamics, information theory, econometrics, and biology. The presented case study applies these indicators to a fleet of industrial assets, introducing innovatively the entropy concept to the field...

The risk quantification is one of the most critical areas in asset management (AM). The relevant information from the traditional models can be shown in risk matrices that represent a static picture of the risk levels and are according to its frequency and its impact (consequences). These models are used in a wide spectrum of knowledge domains....

The aim of this paper is to remark the importance of new and advanced techniques supporting decision making in different business processes for maintenance and assets management, as well as the basic need of adopting a certain management framework with a clear processes map and the corresponding IT supporting systems. Framework processes and...

The purpose of any asset is to provide value to the organization and its stakeholders. In Asset Management, the concept of value encompasses quantitative and qualitative, as well as tangible and intangible benefits that assets may provide to an organization. The definitions of asset and value are not only closely linked but also complementary....

BIM models are transforming the way buildings or, in more general terms, facilities or infrastructures are conceived, designed, constructed and managed. But current use of BIM concentrates on preplanning, design, construction and project delivery rather than maintenance and operation management. This despite the fact that it is estimated that...

This contribution is intended to observe special features presented in physical assets for defence. Particularly, the management of defence assets has to consider not only the reliability, availability, maintainability and other factors frequently used in asset management. On the contrary, such systems should also take into account their...

Regarding the implementation of smart technologies in Product Service Systems (PSS), this research proposes the SEEM-Smart Methodology as a model aimed at promoting innovations that provides better support for the development of Smart PSS. The methodology builds further by taking a data driven approach ensuring that both customer needs and...

This research examines how Industry 4.0 technologies such as artificial intelligence (AI), the Internet of Things (IoT), and digital twins (DT) are used in the digital transformation process of warranty management. This research focuses on converting traditional warranty management practices from reactive systems to predictive and proactive...
