Abstract: The lifetime problem of a closed discrete renewal censored δ shock model was studied by using condition method and probability method. The explicit expressions of the lifetime properties such as reliability and moment of lifetime of the model were obtained, the lifetime distribution and the mean lifetime of the model were applied to specific distributions and performed numerical simulations.
