【摘要】：基于极大似然估计,提出一种将混合爱尔朗分布(HEr D)用于电梯客流到达分布拟合的方法。基于回归方法分析HEr D待定参数之间的规律,发现混合比例α和尺度参数λ均与变异系数的平方c_x~2相关,因此,将HEr D的多个待定参数约简为一个尺度参数,并给出由一阶矩和c_x~2确定尺度参数的方法。将其与指数分布、正态分布等方法对成都CBD高层写字楼的工作日早高峰电梯客流到达时间间隔进行概率分布拟合,结果表明,约简前后的HEr D拟合精度均优于其他分布,且稳定性较高。
[Abstract]:Based on the maximum likelihood estimation, a hybrid Ellan distribution (HEr D) is proposed to fit the arrival distribution of elevator passenger flow. Based on the regression method, the law between the undetermined parameters of HEr D is analyzed. It is found that both the mixed proportion 伪 and the scale parameter 位 are related to the square c _ x 鈮，
