Abstract:Aiming at those mechanical systems which can carry on multiple maintenance in the whole life period, a basic maintenance decision model was put forward based on time-varying reliability of the system, and the precondition of establishing the model, the modeling thought and the basic ideas of the model were expounded.The basic problems the model was going to solve were also presented, including calculating the system maintenance intervals and the system reliability change, and other important problems.Finally, a calculation example was put forward, in which the model calculation program and the data curve fitting were done. In the calculation example, expressions of the system's maintainability parameters were obtained, which proves the feasibility of the model. 
Keywords:time-varying  reliability  maintenance model  maintenance interval
