A Fuzzy Petri Nets Model for Computing With Words (2009)

Cao, Yongzhi, Chen, Guoqing

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 automata and thus are...

A hierarchy of behavioral equivalences in the $\pi$-calculus with noisy channels (2008)

Cao, Yongzhi

The $\pi$-calculus is a process algebra where agents interact by sending communication links to each other via noiseless communication channels. Taking into account the reality of noisy channels, an...

Probabilistic Automata for Computing with Words (2006)

Cao, Yongzhi, Xia, Lirong, Ying, Mingsheng

Usually, probabilistic automata and probabilistic grammars have crisp symbols as inputs, which can be viewed as the formal models of computing with values. In this paper, we first introduce...

Retraction and Generalized Extension of Computing with Words (2006)

Cao, Yongzhi, Ying, Mingsheng, Chen, Guoqing

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 numbers, Ying...

Cartan Determinants of Cellular Algebras (2006)

Zhu, Ping, Cao, Yongzhi

Let A be a finite-dimensional cellular algebra over a field. It is shown that the Cartan determinant of A is a positive integer; furthermore, the Cartan determinant of value 1 is equivalent to the...

CARTAN DETERMINANTS OF CELLULAR ALGEBRAS (2006)

Zhu, Ping, Cao, Yongzhi

Let A be a finite-dimensional cellular algebra over a field. It is shown that the Cartan determinant of A is a positive integer; furthermore, the Cartan determinant of value 1 is equivalent to the...

State-Based Control of Fuzzy Discrete Event Systems (2005)

Cao, Yongzhi, Ying, Mingsheng, Chen, Guoqing

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 introduced...

Similarity-Based Supervisory Control of Discrete Event Systems (2004)

Cao, Yongzhi, Ying, Mingsheng

Due to the appearance of uncontrollable events in discrete event systems, one may wish to replace the behavior leading to the uncontrollability of pre-specified language by some quite similar one. To...

Observability and Decentralized Control of Fuzzy Discrete Event Systems (2004)

Cao, Yongzhi, Ying, Mingsheng

Fuzzy discrete event systems as a generalization of (crisp) discrete event systems have been introduced in order that it is possible to effectively represent uncertainty, imprecision, and vagueness...

Supervisory Control of Fuzzy Discrete Event Systems (2004)

Cao, Yongzhi, Ying, Mingsheng

In order to cope with situations in which a plant's dynamics are not precisely known, we consider the problem of supervisory control for a class of discrete event systems modelled by fuzzy automata....
