基于改进层次分析法对航天发射安全风险的评估OACSTPCD

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.
