For all students who wish to understand current economic and business literature, knowledge of mathematical methods has become a prerequisite. Clear and concise, with precise definitions and theorems, Werner and Sotskov cover all the major topics required to gain a firm grounding in this subject including sequences, series, applications in finance, functions, differentiations, differentials and difference equations, optimizations with and without constraints, integrations and much more.Containing exercises and worked examples, precise definitions and theorems as well as economic applications, this book provides the reader with a comprehensive understanding of the mathematical models and tools used in both economics and business.

In an environmental life cycle assessment of products (LCA), an unambiguous, scientifically based, ‘objective’ attribution of material and energy flows to a product is pure fiction. This is due to the fundamental epistemological conditions of LCA as a modelling process under the complexity of our socio-economic system. Instead, various mental models and values guide this attribution. This leads to a functional model in a specific decision situation.This book shows for the first time how mental models and values influence this attribution in the life cycle inventory step of LCA. One of the key findings is that the different management rules for a sustainable use of materials must be taken into account for the attribution of material and energy flows to a product. Otherwise, improvement options recommended by an LCA might turn out to even worsen the environmental situation if reassessed from a meta-perspective.As a consequence of this book, the claim of unambiguitiy(‘objectivity’) of the life cycle inventory must be abandoned. A group-model building process for LCA is developed that allows one to grasp the decision makers' mental models and values in the inventory analysis on a case- and situation-specific basis. Only by this, LCA results will become relevant in a decision-making process.Two case studies on the modelling of recycling and other end-of-life options of aluminium windows and beech wood railway sleepers in LCA complement the methodological part.This book is a ‘must have’ for researchers, consultants and practitioners in the fields of decision-oriented life cycle assessment as well as product-related environmental management, modelling and decision-making.

The present book includes a set of selected papers from the 11th International Conference on Simulation and Modeling Methodologies, Technologies and Applications (SIMULTECH 2021) that was held as an online event, from July 7 to 9, 2021.

This present book includes a set of selected best extended papers from the 12th International Conference on Simulation and Modeling Methodologies, Technologies and Applications (SIMULTECH 2022), that was held in Lisbon, Portugal, from July 14 to 16, 2022.

This book includes a set of selected best extended papers from the 13th International Conference on Simulation and Modeling Methodologies, Technologies and Applications (SIMULTECH 2023), that was held in Rome, Italy, from July 12 to 14.

The present book includes a set of selected best extended papers from the 14th International Conference on Simulation and Modeling Methodologies, Technologies and Applications (SIMULTECH 2024), that was held in Dijon, France, from 10-12 July. The conference brought together researchers, engineers and practitioners interested in methodologies and applications of modeling and simulation. New and innovative solutions are reported in this book. A selection was made after the conference, based also on the conference chairs assessment, reviewers’ assessment, quality of presentation, and audience interest, so that this book includes the extended and revised versions of the very best papers of the conference. New and innovative solutions are reported in this book.

Christian Dell (1893–1974), silversmith, Bauhaus master craftsman, and head of the metal workshop of the Frankfurter Kunstschule [Frankfurt Art School], is one of the lesser-known designers of the 20th century. Yet his diverse oeuvre and his impact on design—from the 1930s to the present—deserves to be reappraised. This publication provides a first comprehensive overview of Dell’s work and career, including his training in Hanau, teaching in Weimar and Frankfurt am Main, and contacts to the lighting industry. One of Dell’s iconic lamp designs is the KAISER idell™, an office lamp which is back in production today. Moreover, he was an inspiration to numerous students, whose works are introduced here in more detail. Conceptual sketches, series products, and exquisite individual objects in a wide range of materials are also presented—for Dell’s early work with new types of plastic would go on to inform consumer tastes for decades to come. An exciting monograph on a significant, visionary, and hitherto unrecognised designer of the 20th century.Text in German.
