统计发现,集装箱班轮到港规律在整体和局部两个层面上存在明显差别.在整体上,集装箱班轮到港规律服从泊松分布,体现了随机性特征;在局部上,服从高阶爱尔朗分布,体现了组织特征.对我国某集装箱港口连续3年共计1.56万余条船舶到港时间进行统计分析,完成实证研究,其结果验证了上述现象的正确性.
Abstract
According to statistics, there are some obvious differences between the whole and part in container liner’s arrival discipline. On the whole, the arrival discipline of container liner obeys Poisson distribution which reflects the randomness. But in part, its arrival discipline obeys a high order Erlang distribution which reflects the organized characteristics. Statistical analysis on more than 15 600 ships’ arrival records in continuous 3 years of one Chinese container port was carried out to complete an empirical study, its result proved the correctness of this phenomenon.
