Purpose

The purpose of this paper is to resolve three problems in ship routing and scheduling systems. Problem 1 is the anticipation of the future cargo transport demand when the shipping models are stochastic based on this demand. Problem 2 is the capacity of these models in processing large number of ships and cargoes within a reasonable time. Problem 3 is the viability of tramp shipping when it comes to real problems.

Design/methodology/approach

A commodity-trade forecasting system is developed, an information technology platform is designed and new shipping elements are added to the models to resolve tramp problems of en-route ship bunkering, low-tide port calls and hold-cleaning cost caused by carrying incompatible cargoes.

Findings

More realistic stochastic cargo quantity and freight can now be anticipated, larger number of ships and cargoes are now processed in time and shipping systems are becoming more viable.

Practical implications

More support goes to ship owners to make better shipping decisions.

Originality/value

New norms are established in forecasting, upscaling and viability in ship routing and scheduling systems.

船舶路线和调度系统：预测，升舱和生存能力

目的

本文的目的是解决船舶选路和调度系统中的三个问题。问题1是当基于该需求的运输模型是随机的时，对未来货物运输需求的预期。问题2是这些模型在合理时间内处理大量船舶和货物的能力。问题3是流浪者运输在遇到实际问题时的可行性。

设计/方法/方法

开发了商品贸易预测系统，设计了信息技术平台，并在模型中添加了新的运输要素，以解决因运送不兼容货物而造成的途中船舶加油，低潮港口停靠和保洁成本等流浪问题。 。

发现

现在可以预期到更加现实的随机货物数量和货运量，现在可以及时处理更多的船舶和货物，并且运输系统变得更加可行。

实际影响

船东将获得更多支持，以做出更好的运输决策。

创意/价值

在船舶选路和调度系统的预测，升舱和生存能力方面建立了新的规范。
