Opacity of Fuzzy Discrete Event Systems
Weilin Deng, Jingkai Yang, Cheng Jiang, Daowen Qiu · 2019
Opacity of discrete event systems (DESs) has been well investigated in recent years. However, all the existing researches only focus on crisp models. Note that a lot of practical systems are filled with uncertainties that cannot be accurately characterized by crisp models but can be well handled by fuzzy models. Therefore, the researches of opacity of DESs should be extended to fuzzy models. In this paper, we investigate the opacity of fuzzy DESs, in which both system behaviors and secrets are fuzzy sets rather than crisp sets, and intruders make inferences by means of fuzzy logic instead of classic logic.
