  In this work, we study the problem of supervisory control of networked
discrete event systems. We consider lossy communication channels with bounded
network delays, for both the control channel and the observation channel. By a
model transformation, we transform the networked supervisor synthesis problem
into the classical (non-networked) supervisor synthesis problem (for
non-deterministic plants), such that the existing supervisor synthesis tools
can be used for synthesizing networked supervisors. In particular, we can use
the (state-based) normality property for the synthesis of the supremal
networked supervisors, whose existence is guaranteed by construction due to our
consideration of command non-deterministic supervisors. The effectiveness of
our approach is illustrated on a mini-guideway example that is adapted from the
literature, for which the supremal networked supervisor has been synthesized in
the synthesis tools SuSyNA and TCT.
