According to the characteristics of environmental control and life support system of space station and maintenance support strategy, the reliability allocation method for this system is studied systematically. Firstly, based on the structure and functional relationship of environmental control and life support system, the reliability logical relationship of different functional modules is determined, and based on full analysis about the system mission reliability with periodic replacement maintenance and occasional failure maintenance, the conception of orbital replaceable unit combinations is introduced, the reliability block diagram of environmental control and life support system is established. Secondly, the reliability allocation process for environmental control and life support system is proposed, comparing the advantages and disadvantages about different reliability allocation methods and amount of reliability information that can be obtained, the score method was selected to carry out the system reliability allocation, supplementing and quantifying the traditional score factors. Lastly, through experts score, a case study of environmental control and life support system was provided. The results show that this method can effectively guide the reliability allocation work of environmental control and life support system of space station in design phase.
