Abstract
The present invention discloses a CPS modeling and analysis method based on aspect-oriented grey GSPN. First, according to the specific situation of the CPS to be modeled, an AGGSPN model is constructed; the grey system theory is introduced, and the greying processing method is used to solve the transition firing rate and the triggering probability of the stochastic switch in the AGGSPN model; the Markov method is used to solve the grey steady-state probability of the AGGSPN; a mathematical programming model is constructed based on the obtained grey steady-state probability to solve the final interval grey number representation; finally, the performance indicators of the industrial CPS are analyzed using the final interval grey number representation. The present invention adopts the analysis methods of grey theory, Markov chain and mathematical programming, effectively dealing with the uncertainties in the CPS, so that the results have high precision.
