  1. On the base of thorough analysis of fault characters, the petri net model is introduced and changed into fault petri net ( fpn ) that can be used to settle some critical problems such as complicated faults, degradation competition and one cause with multiple consequence according to the characters of fault evolvement and spreading. in order to predicate the remained life of particular machine under special working conditions, an algorithm was also providcd to analyse the timely characters of the fpn. it is demonstrated that the method provided in this paper can simulate the dynamic evolvement process more appropriate than tranditional methods such as fault tree analysis ( fta ) and can predicate the remained life of the particular machine under special working conditions
