【摘要】：基于極大似然估計(jì),提出一種將混合愛(ài)爾朗分布(HEr D)用于電梯客流到達(dá)分布擬合的方法�；诨貧w方法分析HEr D待定參數(shù)之間的規(guī)律,發(fā)現(xiàn)混合比例α和尺度參數(shù)λ均與變異系數(shù)的平方c_x~2相關(guān),因此,將HEr D的多個(gè)待定參數(shù)約簡(jiǎn)為一個(gè)尺度參數(shù),并給出由一階矩和c_x~2確定尺度參數(shù)的方法。將其與指數(shù)分布、正態(tài)分布等方法對(duì)成都CBD高層寫字樓的工作日早高峰電梯客流到達(dá)時(shí)間間隔進(jìn)行概率分布擬合,結(jié)果表明,約簡(jiǎn)前后的HEr D擬合精度均優(yōu)于其他分布,且穩(wěn)定性較高。
[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 偽 and the scale parameter 位 are related to the square c _ x 鈮，
