This book collects the selected conference papers of the 2022 “Fourth (ICFIE, ICORG, GDORS, CGHMORS) Celebrations” held online on December 28, 2022 in Guangzhou. In addition, 20 selected papers from the 2024 Changchun Fuzzy Information and Engineering Conference are included, a total of 37 papers. The conference was sponsored by 1. International Fuzzy Information and Engineering Association, International Operations Research and Management Society, Guangdong Operations Research Society, and China Guangdong Hong Kong Macao Operations Research Society (in preparation). 2. Operations Research Society Fuzzy Information and Engineering Section. It covers deterministic, stochastic uncertainty topics including computer science and mathematics, operations research and control, artificial intelligence, information and engineering technology barrier-free communication for the disabled, digital logistics and knowledge representation, queuing theory and game theory, algorithms and optimization methods, fuzzy uncertainty topics including fuzzy logic, fuzzy system, uncertain reasoning, etc., promoting interdisciplinary research. It is a valuable reference for scholars, engineers, management professionals, graduate students, undergraduates, and students from vocational education, who are interested in computer science, AI, mathematics, fuzzy mathematics, operations research and management, and their applications in information and engineering as well.
