How to promote the development and application of original Chinese theory?Grey System Theory, is the concern of many scholars. The course group of Grey System Theory in Nanjing University of Aeronautics and Astronautics has established a model that combines research and teaching and a mechanism of cooperation between the domestic and the foreign during its long time of research and teaching. We work closely with our for? eign partners in setting up an international academic organization, cooperating in international projects, building joint laboratories and holding international conferences. Together, we also create and operate international aca? demic journals, open summer schools, publish multilingual textbooks and works, develop modeling software with independent intellectual property rights and arrange exchange visits for teachers and students. All of these have helped us build a stable and long-term relationship of cooperation and promoted the further application and spread of the original Chinese Grey System Theory.
