Abstract�� The theory of virtual maintenance is not fully studied and researches are deficiency in the field of virtual maintenance modeling and simulation. The methodology architecture of virtual maintenance were discussed and built, and virtual maintenance model and simulation control method were studied. The model of virtual maintenance called maintenance task net (MTN) was presented, and MTN based on Petri net can describe maintenance process and the factors including state, action and condition. In addition,the fire rules and the control mechanism of virtual maintenance simulation which is driven by MTN were presented.A case study of the line replaceable unit(LRU) repair of an aircraft was conducted, and the result confirms the validation and feasibility of all the studies, which can become a new technique means for maintainability engineering.
Keywords�� maintainability   virtual maintenance   model   simulation   control
