The Model And Analysis Of Integrated Avionics System Data Bus With Stochastic Petri Net

The thesis' content is modelling and analysis of integrated avionics system data bus with Stochastic Petri Net. The purpose is optimizing bus transmission system by the analysis of integrated avionics system data bus capability parameter.Utilizing Timed Petri Net, Stochastic Petri Net modelling tool and computer tool, simulating and analyzing integrated avionics system data bus, and attaining system time capability parameter are the studying method of the thesis.As a result of studying, we gain three system time capability parameter of monolayer bus framework and two-double bus framework, data bus utilization, length of the data waiting queue and time of system timed, basing on fixed BC control seasonal repertoire Timed Petri Net and Stochastic Petri Net.We also take two conclusions by foregoing result:First of all, the system becomes more and more complex, the system data bus utilization copy result, time of system timed and length of the news waiting queue become more and more precise basing on Stochastic Petri Net. At the same time, the model is visual, vivid, concise and current.Secondly, when it is two-double bus framework, the utilization of data bus and length of the data waiting queue will fall quickly.
