太空系统的适应弹性研究

Research of the Resilience of Space Systems

介绍了一种可提高太空系统在各种威胁场景下正常工作能力的方法—系统适应弹性法,该方法可以定量评估太空系统的适应弹性。针对太空系统的单个威胁、多个不相关威胁、多个相关威胁、全部威胁场景的案例,给出适应弹性的计算公式。通过以上各种假设场景下的计算,得到"存在多种方法来获得一个更具适应性和生存能力的系统"结论。该方法对于定量评估太空系统适应弹性、增强太空系统在恶劣环境下的工作能力具有较高价值,并对改善其他行业系统适应弹性具有借鉴意义。

A method that can improve the ability of an system to support the functions necessary for mis- sion success in spite of hostile action or adverse conditions is introduced, which is a method of the resilience of systems. This method can also be used to quantitative assessment of the resilience for space systems. A formulae is given to calculate resilience of systems in the cases of the single threat, irrelated multi-threat, related multi-threat, and all threats. The cases described above demonstrate that there are many ways to get a more resilient system. This method has a comparatively high-value in quantitative as- sessment of the resilience of space systems in bad conditions, and can also give some reference for other industries to improve the resilience of systems.
