Mathematical Fuzzy Logic in the Emerging Fields of Engineering, Finance, and Computer Sciences

Mathematical fuzzy logic (MFL) specifically targets many-valued logic and has significantly contributed to the logical foundations of fuzzy set theory (FST). It explores the computational and philosophical rationale behind the uncertainty due to imprecision in the backdrop of traditional mathematical logic. Since uncertainty is present in almost every real-world application, it is essential to develop novel approaches and tools for efficient processing. This book is the collection of the publications in the Special Issue “Mathematical Fuzzy Logic in the Emerging Fields of Engineering, Finance, and Computer Sciences”, which aims to cover theoretical and practical aspects of MFL and FST. Specifically, this book addresses several problems, such as:- Industrial optimization problems- Multi-criteria decision-making- Financial forecasting problems- Image processing- Educational data mining- Explainable artificial intelligence, etc

Supply Chain

Traditionally supply chain management has meant factories, assembly lines, warehouses, transportation vehicles, and time sheets. Modern supply chain management is a highly complex, multidimensional problem set with virtually endless number of variables for optimization. An Internet enabled supply chain may have just-in-time delivery, precise inventory visibility, and up-to-the-minute distribution-tracking capabilities. Technology advances have enabled supply chains to become strategic weapons that can help avoid disasters, lower costs, and make money. From internal enterprise processes to external business transactions with suppliers, transporters, channels and end-users marks the wide range of challenges researchers have to handle. The aim of this book is at revealing and illustrating this diversity in terms of scientific and theoretical fundamentals, prevailing concepts as well as current practical applications

Customer satisfaction in Hospitality

La presente tesis doctoral tiene como objetivo principal analizar la satisfacción del cliente en tres hoteles de diferente categoría, desde tres a cinco estrellas, situados en la ciudad de San Petersburgo en Rusia. La estructura de la tesis doctoral se presenta en tres partes bien diferenciadas: (1) Se realiza una profunda revisión sistemática de la literatura sobre la satisfacción del cliente centrándose particularmente en las ciencias sociales y la economía, analizando también las diferencias observadas por regiones geográficas comparando los resultados de la literatura internacional con los obtenidos en revistas científicas rusas; (2) se analiza después las peculiaridades que presenta esta literatura en un contexto más adecuado al objeto de estudio de esta investigación cómo es el turismo donde se presenta un análisis bibliométrico así como un estudio de los principales determinantes y consecuencias de la satisfacción en el campo del turismo; y (3) se presentan dos aplicaciones empíricas utilizando los resultados obtenidos mediante la aplicación de un modelo híbrido multicriterio basado en la lógica borrosa y en la técnica de comportamiento global obtenida por la comparación existente con las soluciones ideales observadas en el conjunto de la muestra analizada. De esta forma, la parte empírica presenta dos trabajos que analizan el papel que juega el género y la edad en la satisfacción experimentada en los hoteles analizando de forma global el conjunto de los hoteles incluidos en la muestra, así como los resultados obtenidos para los hoteles de tres y cuatro estrellas. Los resultados obtenidos permiten concluir que la edad y el género influyen de manera decisiva en la satisfacción del cliente discutiéndose importantes implicaciones de gestión que tienen que considerarse por los agentes económicos implicados.La present tesi doctoral té com a objectiu principal analitzar la satisfacció del client en tres hotels de diferent categoria, des de tres a cinc estrelles, situats a la ciutat de Sant Petersburg a Rússia. L'estructura de la tesi doctoral es presenta en tres parts ben diferenciades: (1) Es realitza una profunda revisió sistemàtica de la literatura sobre la satisfacció del client centrant-se particularment en les ciències socials i l'economia, analitzant també les diferències observades per regions geogràfiques comparant els resultats de la literatura internacional amb els obtinguts en revistes russes; (2) s'analitza després les peculiaritats que presenta aquesta literatura en un context més adequat a l'objecte d'estudi d'aquesta investigació com és el turisme on es presenta una anàlisi bibliomètrica així com un estudi dels principals determinants i conseqüències de la satisfacció en el camp del turisme; i (3) es presenten dues aplicacions empíriques utilitzant els resultats obtinguts mitjançant l'aplicació d'un model híbrid multicriteri basat en la lògica borrosa i en la tècnica de comportament global obtinguda per la comparació existent amb les solucions ideals observades en el conjunt de la mostra analitzada . Així, la part empírica presenta dos treballs que analitzen el paper que juga el gènere i l'edat en la satisfacció experimentada en els hotels analitzant de manera global el conjunt dels hotels inclosos en la mostra, així com els resultats obtinguts per als hotels de tres i quatre estrelles. Els resultats obtinguts permeten concloure que l'edat i el gènere influeixen de manera decisiva en la satisfacció del client discutint importants implicacions de gestió que han de considerar-se pels agents econòmics implicats.The main objective of this dissertation is to analyze customer satisfaction in three different hotels, from three to five stars, located in the city of Saint Petersburg in Russia. The structure of the doctoral thesis is presented in three distinct parts: (1) A thorough systematic review of the literature on client satisfaction is carried out, focusing particularly on the social sciences and economics, also analyzing the differences observed by geographic regions by comparing the results of the international literature with those obtained in Russian scientific journals; (2) we analyze the peculiarities presented by this literature in a context more appropriate to the object of study of this research as is the tourism where a bibliometric analysis is presented as well as a study of the main determinants and consequences of satisfaction in the field of tourism; and (3) two empirical applications are presented using the results obtained through the application of a multicriteria hybrid model based on the fuzzy logic and on the global behavior technique obtained by the existing comparison with the ideal solutions observed in the analyzed sample. Two empirical exercises are presented that analyze the role of gender and age in the satisfaction experienced in hotels by analyzing overall the hotels included in the sample, as well as the results obtained for hotels of three and four stars. The results obtained allow us to conclude that age and gender decisively influence client satisfaction by discussing important management implications that have to be considered by the economic agents involved

Appropriate Wisdom, Technology, and Management toward Environmental Sustainability for Development

The protection and maintenance of environmental resources for future generations require responsible interaction between humans and the environment in order to avoid wasting natural resources. According to an ancient Native American proverb, “We do not inherit the Earth from our ancestors; we borrow it from our children.” This indigenous wisdom has the potential to play a significant role in defining environmental sustainability. Recent technological advances could sustain humankind and allow for comfortable living. However, not all of these advancements have the potential to protect the environment for future generations. Developing societies and maintaining the sustainability of the ecosystem require appropriate wisdom, technology, and management collaboration. This book is a collection of 19 important articles (15 research articles, 3 review papers, and 1 editorial) that were published in the Special Issue of the journal Sustainability entitled “Appropriate Wisdom, Technology, and Management toward Environmental Sustainability for Development” during 2021-2022.addresses the policymakers and decision-makers who are willing to develop societies that practice environmental sustainability, by collecting the most recent contributions on the appropriate wisdom, technology, and management regarding the different aspects of a community that can retain environmental sustainability
