基于Petri网的进近操作管理模型研究

Study on management system model for approach based on Petri net

据世界民航所发生的飞行事故情况看,进近着陆阶段时间短、任务重、环境复杂,是飞行事故多发阶段,占很大的比重,因此进近着陆是保证飞行安全的重要阶段。大多数事故是发生在仪表着陆系统出现故障的非精密进近方式。以机组非精密进近的主要飞行操作为基础建立基于Petri网的事故致因模型,统计分析相关的致因因素,计算相关风险值,通过对数据的分析反馈,形成对相应飞行员的针对性学习及训练的系统性管理模式。

According to the accidents or incidents all around the world , during the approach period , the crew afford most conscious but less time , more complicated situations and tasks .So the approach period could be the most dan-gerous one that we must pay more attention on it .More than a half accidents or incidents have happened when the ILS has failure .A manage system was put forward based on Petri net and 〉.The relevant accident cause factors were statistically analyzed , and the various risks were calcaluted, then the satas were feedback to the manage system to train and manage the crew .
