中文摘要：

有效地刻画一个系统动态变化和状态的不确定性,作为经典离散事件系统的推广,模糊离散事件系统最近被提出并研究。该文用自动机和形式语言的方法研究了由自动机建模的模糊离散事件系统的一些性质,并给出乘积合成系统监督控制器的存在性条件,这些都是离散事件系统对应性质的推广。

英文摘要：

To effectively represent possibility arising from the states and dynamics of a system,fuzzy discrete event systems as a generalization of conventional discrete event systems have been studied recently.Regarding to supervisory control theory,some properties for product composition in fuzzy discrete event systems modeled by fuzzy finite automata are discussed with formal languages and automata.The supervisor existence condition of product composition is proposed as well,which is extension of corresponding res...
