| Abstract: | System dynamic reliability for manufacturing system is investigated based on stochastic failure sequence(SFS) analysis,Petri nets theory and Monte Carlo simulation.The definitions of SFS,importance of sequence,and key components of system are given out.The analysis procedure for SFS is discussed.Analysis model for system reliability is established based on Petri nets theory,the state identification table of the system is built and the reachability tree is created,and all SFSs of the system can be obtained.S... |
