On-orbit maintenance is important means to sustain the reliability of space station. Reliability block diagram and static fault tree analysis are usually applied to measure the system reliability of space station. The results are too conservative due to the disregard of maintenance. Markov method can deal with the measure in case of maintenance. However, due to the possibility of state combinational explosion problem in Markov chain, it is difficult to apply in the space station. The paper investigates a reliability measurement method to consider the contribution of maintenance, and in this way the reliability can be calculated easily. First, check whether the reliability block diagram should be updated by the maintenance condition inspection, and convert the model into dynamic fault tree, then, use Markov transfer chain to calculate reliability. Examples are analyzed with these new methods. The analysis results show that the method can accurately measure the maintenance contribution to the reliability, and the analysis accuracy is better than RBD.
