Neutrosophic Sets and Systems, Volume 91 (2025), presents recent advances in neutrosophic theory and its diverse applications across mathematics, computer science, engineering, and the social sciences. The issue brings together contributions that extend classical models of uncertainty—fuzzy, intuitionistic, and probabilistic—through refined neutrosophic frameworks, including plithogenic, superhyper, quadripartitioned, and n-valued models. Articles explore novel applications of neutrosophic integrals, Markov decision processes, network flows, and dynamical systems, addressing challenges in real-time safety evaluation, vocational education, innovation and entrepreneurship training, curriculum reform, and urban hazard risk analysis. Several contributions propose computational models that integrate neutrosophic logic with optimization, decision-making, and assessment tools, demonstrating their utility in areas ranging from electrical automation and robotics to dance aesthetics and political-ideological education. Collectively, this volume highlights the versatility of neutrosophic approaches in capturing indeterminacy, contradiction, and partial truths, while providing rigorous mathematical tools for complex, uncertain, and interdisciplinary domains.
