From October 16 to 18, the 2026 International Congress of the Grey System and Uncertainty Analysis (GSUA 2026) was successfully held in Nanjing. The event was hosted by GSUA, co-organized by the Grey System Professional Committee, Chinese Society of Optimization, Overall Planning and Economic Mathematics, and organized by the College of Economics and Management (CEM) and the Institute of Grey Systems at Nanjing University of Aeronautics and Astronautics (NUAA).

The opening ceremony was chaired by Prof. Naiming Xie, Vice Dean of CEM. Prof. Yuxin Hang, Deputy President and Member of the Board of NUAA, and Prof. Sifeng Liu, President of GSUA, delivered welcome addresses. Prof. Hang highlighted NUAA’s strengths in interdisciplinary innovation and international talent cultivation, expressing hopes to deepen global academic ties. Prof. Liu reviewed the 44-year development of grey system theory, emphasizing its unique value in addressing "small sample, poor information" uncertainties in the AI era.

The congress gathered nearly 300 experts and scholars from prestigious institutions worldwide. Seven distinguished experts delivered keynote speeches covering cutting-edge topics such as explainable grey AI, supply chain forecasting, and uncertainty management in complex engineering systems.

A major highlight of the event was the unveiling of the AI Knowledge Database of Grey System Theory. Co-built by the NUAA Library and CEM, this database marks a significant step in the digitalization of grey system infrastructure, providing authoritative resources for global researchers.

Additionally, the congress featured two special academic forums and 10 parallel sessions, offering extensive platforms for young scholars to discuss topics ranging from grey prediction models to reliability engineering. Selected papers will be recommended for priority publication in the SCI journal Journal of Grey System.

This successful congress fully demonstrated NUAA's academic strength and international influence in the field of grey systems, injecting new momentum into global academic cooperation.
