船舶到港的不均衡(数学上称之为随机性)是影响码头通过能力的重要因素,因而在码头的设计中,对泊位数、堆(库)场大小、设备能力的选取都与船舶到港的随机性有关。在传统的港口设计方法中对这一因素的考虑体现在对船舶到港“不平衡系数”的研究及应用。而现代的港口设计方法(如计算机模拟方法及排队论方法)则是研究船舶到港的随机规律,即船舶到港所遵从的分布函数。探讨我国船舶的到港是否存在统一的规律性,即求出船舶到港共同遵守的同一分布函数,是一项比较有意义的工作。为达到这一目的需要统计和分析大量港口的历史资料。笔者近几年来在从事计算机模拟方面的工作中,收集、统计了部
The imbalance of ships arriving at ports (referred to mathematically as randomness) is an important factor that affects the passing capacity of terminals. Therefore, in the design of terminals, the choice of berth number, Hong Kong’s randomness. The consideration of this factor in the traditional port design method is reflected in the study and application of the “unbalance factor” of the arrival of ships to the port. The modern port design methods (such as computer simulation and queuing theory method) is to study the ship to Hong Kong random law, that is, the ship to Hong Kong to comply with the distribution function. To explore whether there is a uniform law of arrival of ships in our country, that is, to find out the same distribution function that ships should adhere to when they arrive in port is a more meaningful task. To do this, statistics and analysis of a large number of ports of historical data. In recent years, I have been engaged in the work of computer simulation, collecting, statistics department
