Abstract
On-orbit spacecraft has the characteristics of high cost, high complexity and difficult maintenance. In order to ensure that the spacecraft can meet the on-orbit lifetime, it is necessary to ensure that the subsystems have high reliability and safety. Considering the complexity of multi-subsystem and multi-parameter of the spacecraft, a reliability evaluation method of on-orbit spacecraft based on the dynamic weighted comprehensive evaluation is proposed. The state indexes of the subsystems are unified and standardized. A mathematical model for spacecraft comprehensive evaluation is designed. As a result, the reliability evaluation of on-orbit spacecraft subsystem is realized. The method eliminates the subjectivity of evaluators. It can provide more scientific and reasonable evaluation and comparison results for the reliability of on-orbit spacecraft subsystem.
