This book collects research presented at the Sixth Meeting for Dissemination and Research in the Study of Complex Systems and their Applications (EDIESCA 2025). EDIESCA arises from the need to foster academic and research groups that can carry out scientific research, and technological developments at the national and international level and their dissemination. The meeting promotes participation among graduate students, industry specialists and researchers to establish collaborations on the study of complex systems and their applications that may have a strong impact on the development of new projects.
