This study offers a bibliometric analysis to identify tendencies and trends and establish the most prolific and important countries in Fuzzy systems research and its evolution. The need for a robust mathematical approach that model human-like perceptions, values, and decision-making processes has made Fuzzy systems research grow significantly since its creation in 1965. This research had its epicentre originally in the USA and England and has moved first to Europe and then to Asia, following global trends in other fields of study. Data were retrieved from the scientific database Web of Science. A total of 185,673 documents were revised to identify tendencies and trends and establish the most prolific and influential countries.
Keywords: Fuzzy systems, Bibliometrics, Country analysis, Web of Science
