  In this paper, we propose a novel framework for modeling and analysis of
networked discrete-event systems (DES). We assume that the plant is controlled
by a feedback supervisor whose control decisions are subject to communication
delays and losses. Furthermore, we consider a general setting where the
supervisor sends control decisions to different actuators via different
communication channels whose dynamics are independent. We provide a system
theoretic approach by identifying the state-space of overall networked system
and investigating the dynamic of the entire state-space. Our approach precisely
specifies the roles of the supervisor, the communication channels and the
actuators. Also, we compare the proposed networked DES model with the existing
one and show that the proposed networked model captures physical situations of
networked systems more precisely.
