Quantitative Control of Probabilistic Discrete Event Systems The theory of Supervisory Control for Discrete Event Systems (DES), originally initiated by Ramadge and Wonham [1], is based on a non-probabilistic language framework. However, any practical model for an actual physical process (which in....
