摘要
利用数理统计与概率论的有关理论 ,在定义了以置信区间的长度与船舶交通量日均估计值之比作为“相对误差”的基础上 ,得到了船舶交通量观测时间与精度关系的有关结论。该结论可作为港口规划、实施船舶定线制及确定无线电岸台交换机容量决策的参考依据。
The theories of mathematical statistics and probability theory are used to define the ratio between the length of confidence interval and the average estimation of daily traffic volumes as the 'relative error', some conclusions are drawn on relations between the number of observational days and the accuracy on the estimation of traffic volume. These conclusions may be applied to the harbour planning, establishment vessel traffic separation scheme, and the determination of the numbers of exchanger on shore based radio station.
