Abstract:

Taking the risk identification and control technology of Tiangong space lab No. 1 as a traction, this paper puts forward some suggestions on the phased application of risk identification and control methods. In view of the important risks and the characteristics of space lab assemblies, the relative risk identification method and the downgraded reconstruction risk control method are proposed to identify the major risks of space laboratories from the perspective of relative risks. When Tiangong 1 is unable to control the assemblies, manned spacecraft is used to replace Tiangong 1 to control the space lab assemblies. It avoids the problem that the risk identification results fluctuate too much, and reduces the system risk without increasing equipment redundancy and other sections.

Key words: Space lab, Risk identification, Risk control, Combination
