The TOPSIS method is extended with entropy-AHP weights, and entropy-AHP weights are used instead of subjective weights. A novel decision-making model of TOPSIS integrated entropy-AHP weights is proposed to select the appropriate supplier. Finally, we take the selection of building material suppliers as an example and use sensitivity analysis to show that the combination of the TOPSIS method based on entropy-AHP weights can effectively select the appropriate supplier.

This book reflects the latest research trends, methods, and experimental results in the field of electrical and information technologies for rail transportation, which covers abundant state-of-the-art research theories and ideas. As a vital field of research that is highly relevant to current developments in a number of technological domains, the subjects it covered include intelligent computing, information processing, communication technology, automatic control, etc. The objective of the proceedings is to provide a major interdisciplinary forum for researchers, engineers, academicians, and industrial professionals to present the most innovative research and development in the field of rail transportation electrical and information technologies. Engineers and researchers in academia, industry, and government will also explore an insightful view of the solutions that combine ideas from multiple disciplines in this field. The volumes serve as an excellent reference work for researchers and graduate students working on rail transportation and electrical and information technologies.

This book constitutes the proceedings of the 7th International Conference on Smart Computing and Communication, SmartCom 2022, held in New York City, NY, USA, during November 18–20, 2022. The 64 papers included in this book were carefully reviewed and selected from 312 submissions. SmartCom 2023 focus on recent booming developments in Web-based technologies and mobile applications which have facilitated a dramatic growth in the implementation of new techniques, such as cloud computing, edge computing, big data, pervasive computing, Internet of Things, security and privacy, blockchain, Web 3.0, and social cyber-physical systems. The conference gathered all high-quality research/industrial papers related to smart computing and communications and aimed at proposing a reference guideline for further research.

This book presents a collection of recent research on topics related to Pythagorean fuzzy set, dealing with dynamic and complex decision-making problems. It discusses a wide range of theoretical and practical information to the latest research on Pythagorean fuzzy sets, allowing readers to gain an extensive understanding of both fundamentals and applications. It aims at solving various decision-making problems such as medical diagnosis, pattern recognition, construction problems, technology selection, and more, under the Pythagorean fuzzy environment, making it of much value to students, researchers, and professionals associated with the field.

In this manuscript, we extend the traditional multi-attributive border approximation area comparison (MABAC) method for the multiple-criteria group decision-making (MCGDM) with triangular fuzzy neutrosophic numbers (TFNNs) to propose the TFNNs-MABAC method.

This book presents selected papers from the Proceedings of the International Conference on Geosynthetics and Environmental Engineering, ICGEE 2023, held in Jeju Island, South Korea, covering topic areas in geosynthetic applications and sustainability; civil and structural engineering; and environmental engineering and science. The published articles cover the latest research studies with the focus of discussing the relationship between geotechnical materials and environmental engineering in depth to solve complex geosynthetics issues in civil and environmental engineering. It also highlights state-of-the-art technologies adopted by the relevant industries which are not only commercially viable but also environmentally sustainable. The content of the papers appeals to researchers and industrial practitioners working in the field of geoengineering.
