Preface: 4th International Conference on Applied Mathematics, Modeling Simulation and Automatic Control (AMMSAC 2025)

It is our honor to present the proceedings of the 2025 4th International Conference on Applied Mathematics, Modeling Simulation and Automatic Control (AMMSAC 2025). This conference was successfully held in San Diego, USA during July 19-20, 2025. AMMSAC 2025 aims to provide an ideal academic platform for researchers to present the latest research findings and describe emerging technologies, directions and developments in applied mathematics, modeling simulation, computer science, intelligent manufacturing, and automatic control. As these goals require the cooperation of people from different background, we hope that our research will help to achieve a better and more sustainable future for all. During the conference, we were pleased to be joined by four knowledgeable keynote speakers. More than 40 participants were benefited through each of the 30-35 minutes keynote speech. The parallel sessions were arranged and carefully monitored by the organizing team. We truly believe that AMMSAC 2025 is a great platform for researchers, academician, industry players, and student to brainstorm and exchange research idea, communicate their new research findings and eventually leading the world to meet the sustainable goals.
