Data-Driven Environmentally Sustainable Product Design: A Shift Toward Increased use of Sustainable Design Activities in the Early Design Phase

Modern product design drives the boundaries of innovation by encompassing complex Design-for-X objectives, and the inclusion of multidimensional stakeholders. This growing complexity in product design has left design teams unequipped, as classical design theory is bounded by designer experience, expertise, and cognition. One novel approach to tackling product complexity is to leverage data into improved design processes through data-driven design methods. In this dissertation, data-driven design approaches are presented as a means to explore applied knowledge discovery in product data, with a particular focus on function-based design, life cycle inventory, and life cycle assessment data. Using artificial intelligence approaches ranging from decision trees to graph neural networks, and statistical methods such as kernel density estimation, function-based sustainable design is more readily achievable. This dissertation presents methods for introducing sustainable design knowledge in the early stages of product design through the use of data-driven approaches on historic LCA product data. Here, functional modeling is identified as the entry point to the early design phase that can be altered to meet sustainable design objectives. By using data-driven design methods, components are related to functional performance and estimated environmental impact. The culmination of this work is the creation of a probabilistic data-driven methodology that assesses the environmental impact of functional chains and provides component suggestions that reduce potential environmental impact. The research presented in this dissertation begins with an introduction to data-driven design literature and research opportunities (manuscript one). From these opportunities, manuscripts two and three introduce two function-based design methods for aiding in component function assignment and automated functional modeling. Manuscripts four and five introduce novel sustainable methods that realize the goals of this dissertation to create data-driven sustainable design methods applicable to the early design phase. Expanding on this work, the disparity in product data encourages the exploration of richer data sets. By leveraging multiple data sources, including manufacturing, digital, and other life cycle data, we can look forward to novel approaches in data-driven design for knowledge enrichment in function-based sustainable design

XIII Jornadas de ingeniería telemática (JITEL 2017)

Las Jornadas de Ingeniería Telemática (JITEL), organizadas por la Asociación de Telemática (ATEL), constituyen un foro propicio de reunión, debate y divulgación para los grupos que imparten docencia e investigan en temas relacionados con las redes y los servicios telemáticos. Con la organización de este evento se pretende fomentar, por un lado el intercambio de experiencias y resultados, además de la comunicación y cooperación entre los grupos de investigación que trabajan en temas relacionados con la telemática. En paralelo a las tradicionales sesiones que caracterizan los congresos científicos, se desea potenciar actividades más abiertas, que estimulen el intercambio de ideas entre los investigadores experimentados y los noveles, así como la creación de vínculos y puntos de encuentro entre los diferentes grupos o equipos de investigación. Para ello, además de invitar a personas relevantes en los campos correspondientes, se van a incluir sesiones de presentación y debate de las líneas y proyectos activos de los mencionados equiposLloret Mauri, J.; Casares Giner, V.

Ruleset Minimization in Multi-tenant Smart Buildings

In the last years, many works have proposed Building Management Systems (BMS) or other tools that allowed to actually exploit the smart buildings infrastructures. Such new systems allow users to define their own policies (generally in the shape of rules exploiting logic formulas) to program the building behavior. Multi-user managements is not totally supported in modern BMS though. Multi-tenant implications have not been adequately investigated thus leaving some issues still unsolved. Specifically, a way for minimizing the ruleset keeping its size to the minimum necessary to guarantee the correct behavior of the building is needed. In this paper, a method for minimizing the ruleset of a SmartBuilding will be presented. It has been developed starting from State of the Art boolean logic minimization algorithms that have been firstly introduced in 1950s. Exploiting the knowledge coming from boolean logic circuits and taking into account also the differences with Smart Buildings scenario, a custom algorithm has been conceived. Its effectiveness has been shown by applying it to data collected during an experimental campaign

Role-based Adaptation of Business Reference Models to Application Models: An Enterprise Modeling Methodology for Software Construction

Large software systems are in need of a construction plan to determine and define every concept and element used in order to not end up in complex, unusable, and cost-intensive systems. Different modeling languages, like UML, support the development of these construction plans and visualize them for the system’s stakeholders. Reference models are a specific kind of construction plan, used as templates for information systems and already capture business domain knowledge for reuse and tailoring. By adaptation, reference models are tailored to enterprise-specific application models, which can be used for software construction and maintenance. However, current adaptation methods suffer from the limitations of pure object-oriented development (e.g., identity issues, large inheritance trees, and inflexibility). In this thesis, the usage of roles as the sole adaptation mechanism is proposed to solve these challenges. With the help of conceptual roles, it is possible to create rich model variations and adaptations from existing (industry standard) reference models, and it is simpler to react to model evolution and changing business logic. Adaptations can be specified with more precision by maintaining or even increasing the model’s expressiveness. As a consequence, the role-enriched final application model can be used to describe software systems in more detail, with different perspectives, and, if available, can be implemented with a role supporting programming language. However, even without this step, the application model itself will provide valuable insights into the overall construction plan of a software system by the combination of structure and behavior and a clear separation of relatively stable domain knowledge from its use case specific adaptation

Handbook of Easy Languages in Europe

The Handbook of Easy Languages in Europe describes what Easy Language is and how it is used in European countries. It demonstrates the great diversity of actors, instruments and outcomes related to Easy Language throughout Europe. All people, despite their limitations, have an equal right to information, inclusion, and social participation. This results in requirements for understandable language. The notion of Easy Language refers to modified forms of standard languages that aim to facilitate reading and language comprehension. This handbook describes the historical background, the principles and the practices of Easy Language in 21 European countries. Its topics include terminological definitions, legal status, stakeholders, target groups, guidelines, practical outcomes, education, research, and a reflection on future perspectives related to Easy Language in each country. Written in an academic yet interesting and understandable style, this Handbook of Easy Languages in Europe aims to find a wide audience

The Big Five:Addressing Recurrent Multimodal Learning Data Challenges

The analysis of multimodal data in learning is a growing field of research, which has led to the development of different analytics solutions. However, there is no standardised approach to handle multimodal data. In this paper, we describe and outline a solution for five recurrent challenges in the analysis of multimodal data: the data collection, storing, annotation, processing and exploitation. For each of these challenges, we envision possible solutions. The prototypes for some of the proposed solutions will be discussed during the Multimodal Challenge of the fourth Learning Analytics & Knowledge Hackathon, a two-day hands-on workshop in which the authors will open up the prototypes for trials, validation and feedback
