摘要：Multilevel evaluation indicator system for spacecraft assembly safety was built, considering six aspects: operators, process equipment, operating environment, operation types, objects to be operated, and emergency measures. Based on that, a grey?fuzzy comprehensive evaluation approach was proposed to support the spacecraft assembly safety evaluation. In the approach, analytic hierarchy process and grey degree were applied to construct weight matrix, and the principle with which the appropriate memberships could be determined was taken as a basis for creation of grey-fuzzy comprehensive evaluation matrix. The docking assembly, a typical stage in spacecraft assembly process, was taken as the case study to evaluate its safety level by the proposed grey?fuzzy comprehensive evaluation method, and it was confirmed that the result is coherent with the reality of the accident statistics. The evaluation results can be utilized as a technical basis for developing safety and protective measures, perfecting risk management, and furthermore lowering the risk to minimize economic loss and behind-schedule of project.
