确定船舶到港特性,这是运用运筹学方法(包括排队论和模拟法)决定港口建设规模的一个基本前提,它直接影响着计算或模拟的可靠程度。联合国贸易与发展会议的有关文件曾指出:“散装货船的到港特性最接近于泊松分布,这相当于连续两次到船之间的间隔时间为负指数分布。”对于以上基本是否符合我国情况,尤其是否符合我国内河港口的情况,需要认真地按数理统计的方法进行假设检验。目前国内已有许多同志着手进
Determining the characteristics of a ship to port is a basic prerequisite for determining the size of a port using operational research methods (including queuing theory and simulation), which has a direct impact on the reliability of calculations or simulations. Relevant documents of the United Nations Conference on Trade and Development pointed out: “The arrival characteristics of bulk carriers are closest to the Poisson distribution, which is equivalent to the negative exponential distribution of the interval between two consecutive ships.” For the above basic compliance with China The situation, especially whether it is in line with the situation of China’s inland ports, requires careful hypothesis testing according to mathematical statistics. At present, many comrades have already started to enter China
