A Study on Reliability of Manufacturing System Based on Petri Net

Petri net has been used in system modeling and analyzing in many practical systems, but the system reliability has never been considered before, that is, system modeling and analysis were done based on supposing that there were no faults and no need to repair in system resources (equipment). Actually, a practical system is often at fault and needs repairs, so Petri net model does not really represent the action of the system to a certain extent. In this paper, theory of reliability is introduced to Petri net, Petri net model of repairable system is built, and the analysis method of system model is given. The importance is illustrated by imitating a product system.
