The International Symposium on Integrated Uncertainty in Knowledge Modelling and Decision Making (IUKM) aims to provide a forum for exchanges of research results, ideas for and experience of application among researchers and practitioners involved with all aspects of uncertainty management and application. The origin of this conference series started in 2010 at Japan Advanced Institute of Science and Technology, Ishikawa, Japan under the title of the International Symposium on Integrated Uncertainty Management and Applications (IUM 2010). The name of the conference series was then changed to its current title at the second edition (IUKM 2011) held in October 2011 at Zhejiang University, Hangzhou, China; and later editions were held in Beijing, China (IUKM 2013), Nha Trang, Vietnam (IUKM 2015), Da Nang, Vietnam (IUKM 2016), Hanoi, Vietnam (IUKM 2018), Nara, Japan (IUKM 2019), Phuket, Thailand (IUKM 2020), respectively.

The Ninth International Symposium on Integrated Uncertainty in Knowledge Modelling and Decision Making (IUKM 2022) will be held in a hybrid mode of both in-person and online during 18-19 March, 2022, and be jointly organized by Japan Advanced Institute of Science and Technology (JAIST) and Osaka University, Japan.
