| 摘 要： | 为有效预防飞行事故的发生,针对飞行事故率具有随机波动性和趋势性的特点,采用模糊均生函数(FMGF)和最优子集回归(OSR)建立飞行事故率预测模型。该方法把FMGF延拓序列作为预测因子加入OSR方程,将FMGF分析和因子筛选相结合作OSR,进而对飞行事故率进行预测。通过对美国空军1988—2004年的飞行事故率进行拟合预测,结果表明:将FMGF模型和OSR模型有机结合,能够有效刻画飞行事故率的随机波动特性,并且其预测结果的相对误差也较小。

| Abstract: | For the purpose of preventing flight accident effectively,aimed at the characteristics of stochastic fluctuation and tendency of flight accident rate,a prediction model for flight accident rate is established by adopting fuzzy mean generating function and optimal subset regression.The method introduces the continuation serial of fuzzy mean generating function into the regression equation of optimal subset as the forecast factors,and predicts the trend of air force flight accident rate by analyzing the optim... |
