供混雜系統(tǒng)建模使用，在MATLAB 6.5以上版本中使用。可以建立5種類型的PETRI網(wǎng)。 The software Petri Net Toolbox, dealing with Petri nets under MATLAB, is presented. It can handle five types of Petri nets(untimed, transition-timed, place-timed,stochastic and generalized stochastic) with finite or infinite capacity. The toolbox is equipped with a user-friendly graphical interface and allows three simulation modes accompanied or not by animation.
