Optimisation at Maritime Ports
Large Scale Truck Scheduling at Ningbo Port, China
This page provides resources from the research at University of Nottingham addressing the scheduling of large scale truck scheduling and crane dispatching problems at Ningbo Port, China, the busiest maritime port in the world in terms of cargo tonnage, handling 888.96 million tons cargoes in 2015.

Truck Scheduling between Ports
A Mixed-Shift Vehicle Routing problem model is built with a long planning horizon of multiple shifts of short shit servicing short-distance ports, and long shift for inland long-distance dry ports. Transport tasks must be completed satisfying the time constraints. The unit driver cost for long shifts is higher than that of short shifts.
The scheduling of trucks aims to minimise the cost of drivers, travel distance, satisfying the time window constraints.
Truck Dispatching in Container Terminal
A dynamic truck dispatching problem at the Ningbo container terminal, where containers need to be transferred between yard blocks and vessels by a fleet of trucks. Both the yard blocks and the quay are equipped with cranes to support loading/unloading operations.
The aim is minimise any unnecessary idle time between quay crane operations and truck traveling time to speed up the container transfer process. The unpredictable port status can affect routing plans which need to be generated within a short calculation time.
