摘要
针对航天发射安全风险评估涉及因素较多和等级划分的模糊性,提出了航天发射安全风险递阶层次的评估指标体系,并利用正态分布密度函数对层次分析法确定的权重指标进行修正,使风险评估结果更加科学合理。可以为航天发射确定安全风险管控重点、优化防控措施提供重要技术支撑。
In response to the complex factors and hierarchical uncertainties involved in space launch safety risk assessment,an indicator framework for the hierarchical space launch safety risk assessment is presented.A normal distribution density function is used to refine the weighting of indicators determined by the analytic hierarchy process,so that the risk assessment results are more scientific and reasonable.The indicator framework helps to identify the key priorities for the safety risk management in space launch activities and to optimize the prevention and control measures.
