(MDPI, 2023-04) Picardo Pérez, Alberto; Galván, Manuel J.; Soltero Sánchez, Víctor Manuel; Peralta-Álvarez, María Estela; Universidad de Sevilla. Departamento de Ingeniería del Diseño; Universidad de Sevilla. TEP022: Diseño Industrial e Ingeniería del Proyecto y la Innovación
The management of the life cycle of the transport network is one of the main challenges of sustainable mobility. Roads and highways cause significant damage to the ecosystem. Specifically, lighting systems contribute to climate change, energy consumption, and human health effects. In this context, this work proposes the combination of life cycle assessment (LCA) with life cycle costing (LCC) to analyze the eco-efficiency of the life cycle of a road, including evaluation of the relative contribution of the lighting system to the total impact. Four scenarios were included in the model: (S1) high-pressure sodium lamps with ballast powered from the grid; (S2) halogen lamps powered from the grid; (S3) light-emitting diode lamps powered from the grid; and (S4) light-emitting diode lamps powered from a standalone photovoltaic system. The life cycle stages of raw material extraction, construction, use, maintenance, and end of road life were included in the analysis. The results show that scenarios S3 and S1 are the most eco-efficient relative to the less favorable S2 scenario (80% and 74% lower, respectively). Scenarios with the least environmental impact are the most economically viable.
A Finite Element Analysis of a New Dental Implant Design: The Influence of the Diameter, Length, and Material of an Implant on Its Biomechanical Behavior

It is widely recognized that excessive stress and/or strain can lead to peri-implant bone atrophy; therefore, the clinical success of dental implants is intrinsically related to their biomechanical behavior. This study evaluates the influence of the diameter, length, and material [Ti6Al4V (α+β Ti) and Ti35Nb7Zr5Ta (β-Ti)] of a novel cylindrical dental implant on stress and strain levels within maxillary bone of type II quality. The implant design aims to ensure an appropriate distribution of stresses and strains within the peri-implant bone structures (cortical and trabecular bones) while also facilitating surgical machining by requiring a simple, linear, and less expensive bone incision. This approach minimizes the risk of thermal necrosis, a common complication in osteotomies for conical implants that can lead to peri-implant bone loss. Using finite element analysis, stress and strain patterns were evaluated in the maxillary second premolar region under static delayed loading. The results reveal that the cortical bone strains remained below the critical threshold (0.003) to prevent resorption. In the trabecular bone, only larger diameter/length configurations satisfied the previous strain criterion. In all simulations, trabecular bone stress remained below 3 MPa, whereas cortical bone stress peaked at 78 MPa. Notably, the implant model with the largest diameter/length minimized stress and strain concentrations in type II bone when compared to smaller designs, thereby demonstrating its biomechanical advantage.

This study introduces an innovative solution to address the challenges arising from the volatile natural gas market and the growing integration of renewable energy sources within the industrial sector. The research strives to confront this challenge by including renewable methanol (CH3OH) and converting it into methane (CH4), with an intermediate step involving synthesis gas (CO/H2) by using concentrating solar power. This approach provides a sustainable and adaptable solution to reduce dependence on natural gas. The process entails a methanol decomposition reaction at moderate temperatures (<350 °C). Subsequently, the synthesis gas is compressed to 40 bar, stored, and discharged through a methanation process that can be conducted at high temperatures (>500 °C). The resulting methane is used as fuel for gas turbines and can also serve as feedstock in the chemical industry. The simulations were conducted in ASPEN HYSYS and yielded overall system efficiencies exceeding 29% and roundtrip efficiencies of 44%. Through techno-economic optimisation of the reaction conditions, competitive levelized fuel costs (LCOF) of €172/MWh and future LCOE values of €145/MWh were achieved. These findings present an innovative strategy for integrating gas turbine cycles and additional conversion pathways for green methanol.
A Framework for Sustainable Manufacturing: Integrating Industry 4.0 Technologies with Industry 5.0 Values
(MDPI, 2024-02) Martín-Gómez, Alejandro Manuel; Agote-Garrido, Alejandro; Lama-Ruiz, Juan Ramón; Universidad de Sevilla. Departamento de Ingeniería del Diseño; Universidad de Sevilla. TEP022: Diseño Industrial e Ingeniería del Proyecto y la Innovación
The limitations imposed by resource scarcity and the imperative to mitigate adverse environmental and societal impacts have intensified the urgency of developing more sustainable manufacturing systems. Simultaneously, the rapid development and implementation of new technologies is exacerbating the digital divide among vulnerable workers. Concomitantly, the enabling technologies stemming from Industry 4.0 offer significant potential to enhance the competitiveness of manufacturing systems. However, the impact of these enabling technologies on achieving sustainable manufacturing remains uncertain. This paper embarks on a comprehensive exploration to address this knowledge gap. Initially, it assesses the suitability of each enabling technology within Industry 4.0 across the economic, social, and environmental dimensions of sustainability. Subsequently, the needs of the production process are studied to characterize its sustainable performance. For this, the ASTM E3012-22 standard is introduced. Building upon this foundation, the incorporation of Industry 5.0 is introduced to guide the selection of enabling technologies for sustainability based on its core values, encompassing sustainability, human-centricity, and resilience. The integration of new technologies guided by these values can help bridge the technological divide among vulnerable workers. Finally, a theoretical framework is proposed to enable the design of sustainable manufacturing systems guided by Industry 5.0 values. This framework enables the seamless integration of enabling technologies, machinery, and human expertise throughout the system life cycle.
A holonic framework for managing the sustainable supply chain in emerging economies with smart connected metabolism
(Elsevier, 2019-02) Martín-Gómez, Alejandro Manuel; Aguayo-González, Francisco; Luque Sendra, Amalia; Universidad de Sevilla. Departamento de Ingeniería del Diseño; Universidad de Sevilla. TEP022: Diseño Industrial e Ingeniería del Proyecto y la Innovación
Since their origins, human societies have integrated into the natural environment, where social metabolism that identified the interactions between society and nature was established. This social metabolism enables the flows of energy and materials between social and natural environments to be analyzed and quantified. However, in the last century, many societies have undergone a transformation from an agricultural to an industrial system. Thus, labour, as a generator of economic capital through the supply chain, has provoked a loss of natural and social capital, especially in emerging economies, thereby generating the metabolic rift. This situation can be mitigated and reversed through a circular economy, the use of digital and technological enablers of Industry 4.0 and the incorporation of an organizational enabler such as the holonic paradigm. The integration of these enablers has given rise to the development of the cyber-physical holon, which incorporates inherently sustainable concepts and allows the analysis of distributed complex systems. This paper proposes a holonic framework for multiscale and multilevel Adaptive and Integrated Sustainable Supply Chain Management (AISSCM). This framework supports a smart connected social metabolism integrated within the natural environment and oriented towards mitigation and reversal of the metabolic rift, through the processes of adaptation and integration to enable the co-evolution of the supply chain within the environment. The framework developed is applied to a family of products through their sustainable supply chain based on circularity. This proposal is developed to enable the necessary transition towards sustainable societies.
A life cycle analysis of ionizing radiation shielding construction systems in healthcare buildings
(Elsevier, 2021-09) Sánchez-Barroso, Gonzalo; Botejara-Antúnez, Manuel; García-Sanz-Calcedo, Justo; Zamora-Polo, Francisco; Universidad de Sevilla. Departamento de Ingeniería del Diseño; European Regional Development Fund Research Projects GR18029; Universidad de Sevilla. TEP022: Diseño Industrial e Ingeniería del Proyecto y la Innovación
Optimization of material resources, energy efficiency and reduction of environmental impact are basic aspects in selection of a construction system. The aim of this study is to evaluate the environmental impact generated by different shielding systems for walls of an X-ray room in healthcare buildings. Eight commercial construction systems for anti-X shielding were analysed. A Life Cycle Assessment (LCA) was performed by SimaPro using the Ecoinvent database, and a single-score damage category analysis was performed for midpoint and endpoint levels. Prices of installation and working time employed in the construction of a functional unit of each system were obtained. Solutions with clay brick, cast-in-place reinforced concrete and sprayed concrete were the most favourable for the different categories. Sprayed concrete obtained 6.739 points/m² of against 165.12 points/m² of rolled steel option. The damage to human health occupies between 41% and 87% of the total impact in the protection areas. The impact category of human toxicity is also the broadest in the midpoint approach. Considering time and cost of implementation, clay brick solutions proved to be the most favourable, along with cast-in-place reinforced concrete and barite concrete. System #6 is the most environmentally friendly, 1.6 times less than the next one (which is #4), although its unit price is 1.94 times the cheapest (which is #2) and its execution time is 1.89 times the lowest (which is #2 again). The knowledge generated in this study will improve investment decision making for the planning departments of the Sanitary Systems, obtaining an economic, social and environmental benefit. The main novelty of the work lies in the object of the study (X-ray room) as well as in the integration of LCA and economic aspects.

Product development durations are being drastically reduced, thanks, amongst other reasons, to the use of design automation techniques. But this trend is observed in large companies and to a much lesser extent in SMEs. This article seeks to research the possibility of finding suitable automation technologies for this type of enterprises. Automating the development of commercial offers in SMEs can be a good starting point to the change in this trend. Focusing on this objective, the necessary requirements that a tool of this type must have are established. Different models of assistants have been developed and analysed on different products, deducing from their results an ideal system architecture and methodology. This solution is based on design tables, a technology that links data from a spreadsheet, implements the company’s design process, with parameters of a three-dimensional CAD model, which represents the solution. The rest of the documents that constitute the commercial offer and the possibility of linking them with verification tools are derived from this design core. The main conclusion is the current viability of this method, anticipating the improvement of many aspects, mainly highlighting the link with the rest of the life cycle phases through interoperability tools.
A new multi-criteria decision-making approach for the design and selection of materials and manufacturing processes of toys for children with autism
(Elsevier, 2024-08) Cañete Yaque, Raquel; Picardo Pérez, Alberto; Trueba Muñoz, Paloma; Torres Hernández, Yadir; Peralta-Álvarez, María Estela; Universidad de Sevilla.

The efficiency and comfort of daily tasks are intricately shaped by the dynamic interaction between users and technology. User perceptions wield significant influence over initial judgments, impacting user behavior, attitudes, and the overall connection with the product. In the context of childhood development, the influence of toys on accurate sensory integration within the environment is particularly important, especially for children with autism spectrum disorder, whose sensory responses differ from typically developing children. During the design phase, the correct selection of materials and manufacturing processes ensure a seamless and comfortable interaction between children and products. This includes safety, lightweight construction, enhanced sensory engagement, durability against environmental conditions, environmental sustainability, and cost-effectiveness. There is very limited scientific literature dedicated to the analysis of essential material properties for toys, particularly none were found for children with autism. This work studies the main material properties (both technical and design-related) that need to be considered when designing products for children with autism. A multi-criteria decision-making (MCDM) was performed using the Ansys Granta Edupack software to establish an optimized selection of materials and manufacturing processes. To prioritize the essential material properties, the multi-criteria analysis considered three variable groups: (1) technical and design properties based on two sensory profiles (hypersensitive and hyposensitive user), (2) social properties, and (3) economic, quality, and environmental properties. The proposal is applied in a case study of the design of a smart toy.
A Powerful Tool for Optimal Control of Energy Systems in Sustainable Buildings: Distortion Power Bivector
(MDPI, 2021-04) Castilla Roldán, Manuel-Viggo; Martín Moreno, Francisco Ignacio; Universidad de Sevilla. Departamento de Ingeniería del Diseño; Universidad de Sevilla. HUM1008: Arquitectura, Patrimonio y Ecología
In the field of building constructions, there is undeniably a growing need to optimize the energy systems which are a key target in new modern constructions and industrial buildings. In this sense, energy systems are being traced for the development of energy distribution networks that are increasingly smart, efficient, and sustainable. Modern generation and distribution energy systems, such as microgrids control systems, are being affected by the presence of linear and nonlinear loads, resulting a distorted voltage and current waveforms. Thus, it is stated that industrial and residential building heating and cooling loads behave essentially like sources of harmonics. This paper presents a new framework based on geometric algebra (GA) to the definition of a multivectorial distortion power concept, which is represented by a bivector that is geometrically interpreted to distinguish the rotated distortion and distortion power bivectors in these kinds of loads. Both bivectors, and their relations to the phase angles of distorted voltage are the main subject of this paper to interpret an optimal control of building energy. Numerical examples are used to illustrate of the suggested distortion power concept, as well as the information it provides for energy control in new buildings in a more sustainable way.

(MDPI, 2020) Luque Sendra, Amalia; Heras García de Vinuesa, Ana de las; Ávila-Gutiérrez, María Jesús; Zamora-Polo, Francisco; Universidad de Sevilla. Departamento de Ingeniería del Diseño; Universidad de Sevilla. TEP022: Diseño Industrial e Ingeniería del Proyecto y la Innovación
This paper presents a conceptual framework for the optimization of environmental sustainability in engineering projects, both for products and industrial facilities or processes. The main objective of this work is to propose a conceptual framework to help researchers to approach optimization under the criteria of sustainability of engineering projects, making use of current Machine Learning techniques. For the development of this conceptual framework, a bibliographic search has been carried out on the Web of Science. From the selected documents and through a hermeneutic procedure the texts have been analyzed and the conceptual framework has been carried out. A graphic representation pyramid shape is shown to clearly define the variables of the proposed conceptual framework and their relationships. The conceptual framework consists of 5 dimensions; its acronym is ADAPTS. In the base are: (1) the Application to which it is intended, (2) the available DAta, (3) the APproach under which it is operated, and (4) the machine learning Tool used. At the top of the pyramid, (5) the necessary Sensing. A study case is proposed to show its applicability. This work is part of a broader line of research, in terms of optimization under sustainability criteria.
Air Quality Assessment During the Initial Implementation Phase of a Traffic-Restricted Zone in an Urban Area: A Case Study Based on NO₂ Levels in Seville, Spain
(MDPI, 2025-02-25) Pastor-Fernández, Andrés; Lama-Ruiz, Juan Ramón; Otero-Mateo, Manuel; Cerezo Narváez, Alberto; Ramírez-Peña, Magdalena; Sánchez-Alzola, Alberto; Universidad de Sevilla.

Traffic-related air pollution significantly affects air quality. Many cities have introduced low emission zones (LEZs) to restrict urban transport. Nitrogen dioxide (NO₂) is a dangerous pollutant associated with adverse health effects, such as respiratory diseases, cancer, and death. This research aimed to evaluate the impact of implementing an LEZ during an informative period in which no fines were imposed on vehicles. The methodology consisted of several phases. Firstly, the legal levels to guarantee compliance with air quality standards of the Directive 2008/50/EC were studied. Secondly, this study analyzed the temperature and wind speed patterns of the city under investigation. Finally, an in-depth statistical study evaluated the impact of the LEZ at each air quality monitoring station throughout the municipality. The case study focused on Seville, Spain, using data from 2022, 2023, and the first quarter of 2024, the latter corresponding to the reporting period without fines. The results reveal a wide dispersion and periodicity in NO₂ concentrations at the monitoring stations. Seville complied with NO₂ air quality regulations before the implementation of the LEZ, with similar seasonal patterns observed. A low overall impact was observed in the first three months after implementation. This methodology can be used universally

Finalmente, los resultados se ilustran mediante un ejemplo numérico.
An Evolutionary Modular Product Development Under Circular Economy Approach
(MDPI, 2024-12-05) Córdoba-Roldán, Antonio; Martín-Gómez, Alejandro Manuel; Rodríguez-Núñez, Marina; Lama-Ruiz, Juan Ramón; Universidad de Sevilla. Departamento de Ingeniería del Diseño; Universidad de Sevilla. TEP022: Diseño Industrial e Ingeniería del Proyecto y la Innovación
The incorporation of new technologies and materials, as well as the rapid evolution of products, makes it necessary to guide the product design and development process from bio-inspired perspectives that promote a circular economy. Among the proposals based on a bio-inspired solution is the framework called the Genomic Model of Eco-innovation and Eco-design, which integrates the Cradle-to-Cradle paradigm, material and substance flow analysis, along with all aspects present in the life cycle analysis of products. In this work, innovation is carried out through the integration of genetic algorithms as a methodological tool for optimizing the modular product design in the definition of the genotype within the aforementioned framework. Through a systematic approach, it analyzes how the modular reconfiguration of products, based on circular design principles and genetic optimization, can contribute to a significant reduction in resource use and waste generation. The proposed methodology is applied to a practical case based on the redesign of a small household appliance, demonstrating its potential to facilitate the implementation of circular economy strategies in the early stages of the product design and development process for studying product modularity, with the aims of improving its design and reducing its impact.

(Elsevier, 2020-10) Peralta-Álvarez, María Estela; Soltero Sánchez, Víctor Manuel; Universidad de Sevilla. Departamento de Ingeniería del Diseño; Universidad de Sevilla. TEP992: Diseño e Ingeniería; Universidad de Sevilla. TEP137: Máquinas y Motores Térmicos
Currently, ways to approach the design of Cyber Physical Systems in Industry 4.0 are under development. Emerging concepts of Smart Factories require the development of specialized knowledge; new working methods are also needed to manage the transition from conventional industry to industry 4.0. To achieve this objective, fractal theory could provide the appropriate knowledge and tools. Fractal systems applied to manufacturing have been widely used over the last decades to design complex adaptive systems: it allows the introduction of resilience requirements (capacity to react to changes in a turbulent environment) and to reduce the complexity of its structure, operation and management. In order to know the potential and the possibility of applying fractal theory to the design of systems in Industry 4.0, this article reviews the publications that develop fractal systems for manufacturing engineering. The review includes contributions published between 1985 (approximate date of the first works on the theory applied to manufacturing engineering) and 2019. The objective is to gather those strategies, methodologies and successful case studies that can be useful for the approaches of Industry 4.0 and to define a set of future lines of work for the adaptation of the fractal theory to the new challenges posed by Industry 4.0.
Analysis of indirect power cycles for a novel methanol-to-methane TCES-CSP system
(Elsevier Ltd., 2024-08-15) Rodríguez Pastor, Diego Antonio; Marqués-Valderrama, Israel; Soltero Sánchez, Víctor Manuel; Chacartegui, Ricardo; Universidad de Sevilla. Departamento de Ingeniería Energética; Universidad de Sevilla. Departamento de Ingeniería del Diseño; Universidad de Sevilla. TEP137: Máquinas y motores térmicos
The security of the supply of clean energy resources and the production of renewable fuels for industry are some of the strategies to combat climate change. In this sense, the massive implementation of green fuels that is foreseen forces the industrial park to operate on hydrogen and/or ammonia, methanol and others, with a cost overrun for stakeholders. This work proposes an alternative through a methanol-to-methane conversion system from the intermediate step to synthesis gas. Methanol decomposition is a process that can be produced with solar energy (CSP) at moderate temperatures (<350 °C) and at low cost, whereas methanation is a well-known and industrially mature process that occurs at temperatures < 625 °C. The integration of both processes is employed as a method of solar storage, namely through high-pressure syngas and its discharge for power production in conventional cycles. Recuperative ORC configurations, Rankine steam, and a sCO2 Brayton cycle were integrated; all of them of techno-economic interest, offering round-trip efficiencies higher than 50 % and levelized costs (LCOE) lower than EUR 55/MWh, considering a high-energy methane stream at the outlet. This offers a system that proposes a solution for the massive deployment of methanol as a green hydrogen carrier molecule, where it is capable of cleanly and efficiently storing thermochemical energy and producing high-purity methane at the output, usable in other power cycles, or as an industrial feedstock.
Analysis of Interurban Mobility in University Students: Motivation and Ecological Impact
(MDPI, 2020-12) Cruz-Rodríguez, Javier; Luque Sendra, Amalia; Heras García de Vinuesa, Ana de las; Zamora-Polo, Francisco; Universidad de Sevilla. Departamento de Ingeniería del Diseño; Universidad de Sevilla. TEP022: Diseño Industrial e Ingeniería del Proyecto y la Innovación
The management of mobility in large cities is a complex issue of great interest due to its economic, social, and environmental impact. In this work, the interurban mobility of engineering students from two campuses of the University of Seville is studied. Specifically, this work carries out an analysis of the preferences of students in terms of mobility to their study centres and determines the environmental impact of such mobility in terms of kg of CO2 per student. Three constructs can be found to describe the motivation for their choice of transport: those related to comfort and speed, those related to sustainability and price, and those related to safety. Based on the responses obtained, groups of students are established that enable the design of specific actions in accordance with each of the profiles. From the analysis of the results obtained, recommendations are made for policymakers, and a reflection is given on the impact of the COVID-19 pandemic on this issue.
Analysis of learning motivation in industrial engineering teaching in university of Extremadura
(MDPI, 2020-06) Sánchez-Barroso, Gonzalo; González-Domínguez, Jaime; García-Sanz-Calcedo, Justo; Zamora-Polo, Francisco; Universidad de Sevilla. Departamento de Ingeniería del Diseño; Universidad de Sevilla. TEP022: Diseño Industrial e Ingeniería del Proyecto y la Innovación
Motivational orientations predispose and condition behaviour, and determine the degree of assimilation of concepts by students during their training stage. Knowing them allows professors to conduct their lessons in order to favour maximum achievement for students. The objective of this work is to evaluate the motivation that guides the learning process of Industrial Engineering students at the University of Extremadura (Spain). About three quarters of the students present a high motivation for learning; half of them tend to be result-oriented and less than 10% show a high level of fear of failure. Homogeneous groups were formed based on the level of each dimension, and influential teaching methodologies were discussed. Therefore, it is possible to create a context that favors the acquisition of knowledge by students according to their motivations, and thus achieve maximum academic performance from them. The results shown here may be interesting for the design of promotional activities for SDGs in the university context.
Analysis of Performance Strategies for the Preservation of Heritage Buildings: The Case of Puerto de Santa María
(MDPI, 2023-04) Castilla Roldán, Manuel-Viggo; Universidad de Sevilla. Departamento de Ingeniería del Diseño; Universidad de Sevilla. HUM1008: Arquitectura, Patrimonio y Ecología
Adverse impacts of industrial constructions have been central to debates on sustainable development and this issue is partly due to that the building sector is highly demanding in relation to energy efficiency. The future of an industrial building, given to its link with the production process, is also connected to the activity itself. In this sense, the conservation of the original industrial activity of a wine cellar construction requires very specific values of several microclimate parameters. The accurate modelling of these values is a key tool for analysing the performance of this building typology. The main goal of this paper is to present an integrated methodology to assess and optimize the efficiency and indoor microclimate for evaluating the potential of heritage buildings and acknowledge their features for future opportunities. The integrated model proposed is based on different assessments, which are the essential benchmarks of these buildings. This approach could be also proposed to any other heritage category to evaluate, according to several parameters and aspects, the preservation of its original activity. Due to the importance of natural light in this type of construction, the article presents an application able to simulate and analyse this fundamental aspect of an old winery with the use of advanced simulation tools.

(Elsevier, 2021-04) Heras García de Vinuesa, Ana de las; Relinque-Medina, Fernando; Zamora-Polo, Francisco; Luque Sendra, Amalia; Universidad de Sevilla. Departamento de Ingeniería del Diseño; Junta de Andalucía (Spain) in its programme of projects to promote cross-border cooperation in the Euroregion Alentejo-Algarve-Andalucía; Telefonica Chair “Intelligence in Networks” of the University of Seville (Spain); Universidad de Sevilla. TEP022: Diseño Industrial e Ingeniería del Proyecto y la Innovación
The Sharing Economy has been emerged in recent years as a trend with high growth potential by showing itself to be an innovative model for creating products, services and relationships based on sustainable consumption. The Sharing Economy has emerged as a multidimensional and multidisciplinary concept, which initially only covered areas of the economy and social sciences and which later experienced growth in business, urban planning, tourism, information technology and digital science (industry 4.0) or engineering. This has transformed its development from an economic opportunity to a form of decentralised, equitable and sustainable economy with the creation of new initiatives and companies that have reduced environmental impact by decreasing the use of natural resources. The present study aims to evaluate the evolution of the discourse and the way research has progressed in this incipient sphere of collaborative consumption up to the present day by means of an in-depth analysis of scientific production through bibliometrics and network analysis techniques with the VOSviewer© software and the complete database of publications obtained from the Web Of Science (2152 publications). It also includes the detailed examination of the most relevant bibliographic reviews on Sharing Economics, as well as the main publications on bibliometric analysis. The article evaluates key words, sources, authors, citations, organizations, categories, and countries using various bibliometric techniques. Finally, in the results 5 clusters of thematic categories are obtained where a change in the trend of publications towards the field of clean and green technology is reflected, forming in recent years an agglutinating nucleus of all the disciplines in which “sustainability” acts as the backbone of scientific production. This is a positive development in cleaner production, where institutions and authors from the USA and Europe have risen to the top of the ranking of publications and impact. At a global level, the current commitment to research for the development of accessible, equitable and sustainable products and services is reflected.
