General info

The aim of the 19th World Congress of the International Fuzzy Systems Association and the 12th Conference of the European Society for Fuzzy Logic and Technology, IFSA-EUSFLAT 2021, is to bring together researchers dealing with the theory and applications of computational intelligence, fuzzy logic, fuzzy systems, soft computing and related areas.

The 2021 issue of the IFSA-EUSFLAT congress is special due to joining with three traditional events, namely with AGOP 2021 - International Summer School on Aggregation Operators; IJCRS 2021 - International Joint Conference on Rough Sets, and with FQAS 2021 - International Conference on Flexible Query Answering Systems. We would like to express our thanks to the management of these event for sharing the vision of the joint multiconference.
