Fuzzy Optimization, Decision-making and Operations Research: Theory and Applications
by Madhumangal Pal Chiranjibe Jana Ghulam Muhiuddin Peide LiuAfter developing fuzzy set theory, many contributors focused their research on the extension of fuzzy sets and their computational methodologies, strengthening modern science and technology. In some real-life phenomena, the conventional methods and traditional fuzzy sets cannot be explained, whereas the extension of fuzzy sets and effective new computing methods can explain it adequately. This edited book presents a new view of fuzzy set-measurement methods entitled "Fuzzy Optimization, Decision Making and Operations Research: Theory and Applications", which deals with different perspectives and areas of research. All chapters are divided into three parts: fuzzy optimization, fuzzy decision-making, and fuzzy operation research. The goal of this book is to provide a relevant methodological framework covering the core fields of fuzzy decision-making method, fuzzy optimization method, fuzzy graphics method, fuzzy operations research, fuzzy optimization using graph theory, fuzzy support systems and its real and industrial applications. For many people, fuzzy words' industrial engineering and scientific meanings are still an advanced system for improving modern science and technology. Although fuzzy logic can be applied to many different areas, people do not know how different fuzzy approaches can be applied to various products currently on the market. It is written for professionals who wish to share their expertise, improve their findings, and provide relevant information in the fields of fuzzy methods and their application in decision-making, optimization theory, graph theory and operations research. This book is aimed at experts and practitioners in the fields of fuzzy optimization, fuzzy decision-making, and fuzzy operation research.
Fuzzy Pictures as Philosophical Problem and Scientific Practice
by Jordi CatThis book presents a comprehensive discussion on the characterization of vagueness in pictures. It reports on how the problem of representation of images has been approached in scientific practice, highlighting the role of mathematical methods and the philosophical background relevant for issues such as representation, categorization and reasoning. Without delving too much into the technical details, the book examines and defends different kinds of values of fuzziness based on a complex approach to categorization as a practice, adopting conceptual and empirical suggestions from different fields including the arts. It subsequently advances criticisms and provides suggestions for interpretation and application. By describing a cognitive framework based on fuzzy, rough and near sets, and discussing all of the relevant mathematical and philosophical theories for the representation and processing of vagueness in images, the book offers a practice-oriented guide to fuzzy visual reasoning, along with novel insights into the field of interpreting and thinking with fuzzy pictures and fuzzy data.

Fuzzy Social Choice Models
by Peter C. Casey Michael B. Gibilisco Carly A. Goodman Kelly Nelson Pook John N. Mordeson Mark J. Wierman Terry D. ClarkThis book explores the extent to which fuzzy set logic can overcome some of the shortcomings of public choice theory, particularly its inability to provide adequate predictive power in empirical studies. Especially in the case of social preferences, public choice theory has failed to produce the set of alternatives from which collective choices are made. The book presents empirical findings achieved by the authors in their efforts to predict the outcome of government formation processes in European parliamentary and semi-presidential systems Using data from the Comparative Manifesto Project (CMP), the authors propose a new approach that reinterprets error in the coding of CMP data as ambiguity in the actual political positions of parties on the policy dimensions being coded. The range of this error establishes parties' fuzzy preferences. The set of possible outcomes in the process of government formation is then calculated on the basis of both the fuzzy Pareto set and the fuzzy maximal set, and the predictions are compared with those made by two conventional approaches as well as with the government that was actually formed. The comparison shows that, in most cases, the fuzzy approaches outperform their conventional counterparts.
Fuzzy Solution Concepts for Non-cooperative Games: Interval, Fuzzy and Intuitionistic Fuzzy Payoffs (Studies in Fuzziness and Soft Computing #383)
by Amit Kumar Tina VermaThis book proposes novel methods for solving different types of non-cooperative games with interval/fuzzy/intuitionistic fuzzy payoffs. It starts by discussing several existing methods and shows that some mathematically incorrect assumptions have been considered in all these methods. It then proposes solutions to adapt those methods and validate the new proposed methods, such as Gaurika method Ambika-I-IV, Mehar method and others, by using them for solving existing numerical problems. The book offers a comprehensive guide on non-cooperative games with fuzzy payoffs to both students and researchers. It provides them with the all the necessary tools to understand the methods and the theory behind them.

Fuzzy Stochastic Optimization
by Shuming Wang Junzo WatadaCovering in detail both theoretical and practical perspectives, this book is a self-contained and systematic depiction of current fuzzy stochastic optimization that deploys the fuzzy random variable as a core mathematical tool to model the integrated fuzzy random uncertainty. It proceeds in an orderly fashion from the requisite theoretical aspects of the fuzzy random variable to fuzzy stochastic optimization models and their real-life case studies. The volume reflects the fact that randomness and fuzziness (or vagueness) are two major sources of uncertainty in the real world, with significant implications in a number of settings. In industrial engineering, management and economics, the chances are high that decision makers will be confronted with information that is simultaneously probabilistically uncertain and fuzzily imprecise, and optimization in the form of a decision must be made in an environment that is doubly uncertain, characterized by a co-occurrence of randomness and fuzziness. This book begins by outlining the history and development of the fuzzy random variable before detailing numerous optimization models and applications that include the design of system controls for a dam.

Förderung der Entwicklung im mittleren und höheren Lebensalter: Eine Perspektive der positiven Psychologie
by Irina Catrinel CrăciunDieses Handbuch integriert und erörtert eine wachsende Evidenzbasis zur individuellen Entwicklung im mittleren und späten Erwachsenenalter. Das Buch enthält eine umfassende Analyse dessen, was Wachstum in der Lebensmitte und im höheren Alter bedeutet, und zeigt auf, wie verschiedene Entwicklungsbereiche miteinander verwoben sind (d. h. körperliche, kognitive, soziale und emotionale Entwicklung sowie Persönlichkeitsentwicklung). Da die Kluft zwischen Theorie und Praxis immer noch ein Problem in der Entwicklungsforschung darstellt, zielt das Handbuch auch darauf ab, anschauliche Beispiele für Prävention und Intervention aus der Perspektive der positiven Psychologie zu liefern. Diese wurden so ausgewählt, dass sie eine Vielzahl von Themen repräsentieren, die für die individuelle Entwicklung relevant sind und bei denen die Forschung die Praxis beeinflusst, von Glück, Großelternschaft, Liebe und Sexualität bis hin zu Einsamkeit, Depression, Angst, Suizidprävention und Bewältigung des Todes.Dieses Handbuch ist ein unverzichtbares Hilfsmittel für Studenten und Forscher, die in den Bereichen Entwicklungspsychologie, Gesundheitspsychologie, Gerontologie und öffentliche Gesundheit arbeiten. Es ist auch für Praktiker wie Berater, Life Coaches, Psychotherapeuten, Organisationspsychologen, Gesundheitsfachleute, Sozialarbeiter und Planer im Bereich der öffentlichen Gesundheit von Interesse.
Förderung der Motivation im Mathematikunterricht des Berufskollegs: Konzeption und Evaluation eines motivierenden Lehr-Lern-Arrangements (Studien zur theoretischen und empirischen Forschung in der Mathematikdidaktik)
by Julia Elena KillingDie vorliegende Arbeit stellt die Konzeption und Evaluation von zwei Lehr-Lern-Arrangements zum Themengebiet der Stochastik am Berufskolleg dar. Die Evaluation der beiden Lehr-Lern-Arrangements erfolgt durch die Auswertung der Wirkung auf die Motivation der Lernenden in einer quantitativ quasi-experimentellen Interventionsstudie im Prä-Post-Design. Zur Auswertung wurde die Motivation vor und nach den Lehr-Lern-Arrangements sowie die Leistungsfähigkeit zu Beginn des Lehr-Lern-Arrangements der N = 195 teilnehmenden Lernenden aus fünf Berufskollegs erhoben und kumulativ ausgewertet. Die Auswertung zeigt, dass sich die Motivation der Lernenden lediglich im betrieblichen Lehr-Lern-Arrangement signifikant verbessern ließ. Im anwendenden Lehr-Lern-Arrangement und in der Kontrollgruppe ließen sich keine signifikanten Veränderungen der Motivation feststellen. Ebenfalls ließ sich kein Zusammenhang zwischen der Wirkung der Lehr-Lern-Arrangements auf die Motivation und der vorherigen Leistungsfähigkeit der Lernenden feststellen. Daher lässt sich insgesamt schlussfolgern, dass betriebliche Lehr-Lern-Arrangements einen positiven Einfluss auf die Motivation von Lernenden am Berufskolleg haben.
Förderung der Zahlbegriffsentwicklung bei sehenden und blinden Kindern
by Juliane LeudersDie wissenschaftliche Kenntnislage zur Entwicklung mathematischer Kompetenzen bei blinden Kindern ist lückenhaft, heterogen und teilweise widersprüchlich. Auch für sehende Kinder wurden psychologische Forschungsergebnisse bisher nur teilweise aus didaktischer Perspektive ausgewertet. Juliane Leuders bietet einen umfassenden Überblick über den deutschen und englischsprachigen Forschungsstand zu den Grundlagen des Arithmetiklernens von sehenden und blinden Vorschulkindern und Schulanfängern. Sie thematisiert neuro- und wahrnehmungspsychologische Grundlagen des Hörens und Tastens und erörtert kognitive Prozesse und die Entwicklung des zahlbezogenen Denkens. Im didaktischen Teil beschreibt sie den Kompetenzerwerb im inklusiven Unterricht, die Qualität von Veranschaulichungen und erarbeitet konkrete Vorschläge für die Adaption von Unterrichtsmaterialien.
Förderung diagnostischer Kompetenz angehender Grundschullehrkräfte (Mathematikdidaktik im Fokus)
by Jan Philipp VolkmerDiagnostische Kompetenz ist eine der zentralen Kompetenzen von Lehrkräften. Diese Kompetenz hängt von der jeweiligen diagnostischen Situation ab. Das Analysieren von reichhaltigen Schüler*innendokumenten, wie sie zum Beispiel bei der Bearbeitung offener Lernangebote entstehen, wurde als diagnostische Situation bisher kaum betrachtet. Das vorliegende Buch widmet sich daher der Operationalisierung und Förderung diagnostischer Kompetenz bezüglich der Analyse von Schüler*innendokumenten zu offenen Lernangeboten der Arithmetik. Dazu wird eine Operationalisierung der diagnostischen Kompetenz und insbesondere des diagnostichen Denkens als Synthese bisheriger Forschung vorgeschlagen. Die Operationalisierung stützt sich auf die Adaption epistemischer Aktivitäten und einen adaptierten Prozess des Anpassens und Vergleichens. Weiter werden zwei empirische Studien vorgestellt, die die Wirksamkeit verschiedener Interventionen zur Förderung diagnostischer Kompetenz nachweisen können.
Förderung von diagnostischen Kompetenzen: Eine empirische Untersuchung mit Mathematik-Lehramtsstudierenden (Mathematikdidaktik im Fokus)
by Natalie HockIn der vorliegenden Studie wurde empirisch nachgewiesen, dass eine gezielte Intervention dazu beitragen kann, die Fehler-Ursachen-Diagnosekompetenz von Mathematik-Lehramtsstudierenden zu fördern. Diese spezifische Diagnosekompetenz ist notwendig, um Schülerfehler und deren Ursachen zu diagnostizieren, denn die abschließende Diagnose bildet die Grundlage für eine Differenzierung im Unterricht sowie diverse Förderangebote. Auch in der aktuellen Bildungspolitik erhalten diese Aspekte eine immer stärkere Beachtung aufgrund der zunehmenden Heterogenität der Schülerschaft.
