From the perspective of the fuzzy version, this paper defines the conditional fuzzy entropy of a sequence of fuzzy process, and studies the commutativity behavior of sequential fuzzy entropy in the fuzzy process. Moreover, the commutativity behavior of functions and invariant measures is discussed in those different fuzzy processes. However, our demonstration needs more techniques of topological dynamics and fuzzy analysis.\n                  <\/jats:p>","DOI":"10.3233\/jifs-17793","type":"journal-article","created":{"date-parts":[[2018,3,23]],"date-time":"2018-03-23T12:29:33Z","timestamp":1521808173000},"page":"2021-2029","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["On sequential entropy of fuzzy systems"],"prefix":"10.1177","volume":"34","author":[{"given":"Yun","family":"Zhao","sequence":"first","affiliation":[{"name":"Department of Mathematics, Soochow University, Suzhou, Jiangsu, P.R.
