This article presents a condition assessment model to evaluate the health condition of manned spacecraft avionics that enables the essential capabilities of a manned spacecraft and guarantees the mission success of space flight. Condition assessment based on the integrated system health management is introduced into manned spacecraft avionics to cope with the safety and maintenance necessity. Due to the complexity and the uncertainty of the system, it is a tough task before modular avionics emerged, and there is a rare research-concerning condition assessment for manned spacecraft avionics with fuzziness and simultaneous consideration in system level. A numerical example illustrates the proposed fuzzy evaluation model which takes all criteria into account from a holistic perspective, combines objective tests with subjective judgments and incorporates fuzziness and uncertainty into ranking the manned spacecraft avionics health level using fuzzy analytic hierarchy process with quantitative reliability analytical approaches. The proposed model is demonstrated to solve the condition assessment problem and the impact condition factors for the manned spacecraft avionics health management are revealed.
