摘　　要：航天测控系统容灾能力评估是建设航天测控容灾系统的关键环节。通过对航天测控系统容灾能力评估因素进行深入分析,建立评价指标体系,利用层次分析法(AHP)确定各指标的组合权重;利用模糊评判方法建立模糊评判模型,计算容灾能力的综合评判值并做出决策。按照以上方法评估,航天测控系统的总体容灾能力等级是"较强",但在灾难恢复管理、灾难恢复规划及灾难恢复技术措施等方面还需提高。结果表明,通过将层次分析法和模糊评判方法相结合对容灾能力进行评估,可以为容灾建设提供合理参考依据。Disaster recovery capability evaluation plays an important role in building the space TTC disaster recovery system.By analyzing the main factors which influence the disaster recovery capability of the space TTC system,the set of evaluated indexes was founded,whose weights were calculated by analytic hierarchy process（AHP）.The model for assessment was founded by fuzzy comprehensive evaluation,based on which the comprehensive assessment value of the disaster recovery capability was computed and the decision to make up for the space CCT disaster recovery system was made furthermore.The actual calculated results show that the general disaster recovery capability of the space TTC is relatively strong.But the capability of disaster recovery management,disaster recovery plan and disaster recovery technologies and measures still needs to be strengthened.The application result shows that the approach could evaluate the disaster recovery capability efficiently and provide reasonable consults for building the space TTC disaster recovery system by combining AHP with fuzzy assessment.
