| Abstract: | The concepts of general queue process, general maintenance serve process and relevant time were proposed, considering the out of capability and the shortage of spares. A Petri net formalization model was constructed to describe the queuing system. Based on Petri net model, the analytical formula and simulation method to analyze system performance were studied. By case study, the method to improve system performance was present and calculation precision simplified analytical formula was given. |
