本文提出了一个简单的管网形式的公式，用于模拟全球集装箱航运网络。利用启发式方法对现有集装箱运输网络的成本效率和运动模式进行了研究。该模型能够再现该行业以及个别航运公司和港口的总体收入、成本和集装箱运输模式。研究发现，重新安置空舱的成本占全球机队运营总成本的27%，运力过剩仍然是一个问题。该模型在计算上是有效的。用Java语言实现，在一台奔腾IV计算机上运行一个完整的网络只需一分钟。
This paper presents a simple formulation in the form of a pipe network for modelling the global container-shipping network. The cost-efficiency and movement-patterns of the current container-shipping network have been investigated using heuristic methods. The model is able to reproduce the overall incomes, costs, and container movement patterns for the industry as well as for the individual shipping lines and ports. It was found that the cost of repositioning empties is 27% of the total world fleet running cost and that overcapacity continues to be a problem. The model is computationally efficient. Implemented in the Java language, it takes one minute to run a full-scale network on a Pentium IV computer.
