A Behavioral Distance for Fuzzy-Transition Systems
Yongzhi Cao, Huaiqing Wang, Sherry X. Sun +1
In contrast to the existing approaches to bisimulation for fuzzy systems, we introduce a behavioral distance to measure the behavioral similarity of states in a nondeterministic fu…
Bisimulations for fuzzy transition systems
Yongzhi Cao, Guoqing Chen, Etienne Kerre
There has been a long history of using fuzzy language equivalence to compare the behavior of fuzzy systems, but the comparison at this level is too coarse. Recently, a finer behavi…
A Fuzzy Petri Nets Model for Computing With Words
Yongzhi Cao, Guoqing Chen
Motivated by Zadeh's paradigm of computing with words rather than numbers, several formal models of computing with words have recently been proposed. These models are based on auto…
Retraction and Generalized Extension of Computing with Words
Yongzhi Cao, Mingsheng Ying, Guoqing Chen
Fuzzy automata, whose input alphabet is a set of numbers or symbols, are a formal model of computing with values. Motivated by Zadeh's paradigm of computing with words rather than…
State-Based Control of Fuzzy Discrete Event Systems
Yongzhi Cao, Mingsheng Ying, Guoqing Chen
To effectively represent possibility arising from states and dynamics of a system, fuzzy discrete event systems as a generalization of conventional discrete event systems have been…
