Dispatching Container Flow at Terminals

AGV Dispatching Strategies at Automated Seaport Container Terminals

A key issue in automated seaport container terminals is the assignment of transportation orders to automated guided vehicles (AGVs). For AGV dispatching two basic types of strategies can be applied, which differ by the length of the look-ahead period and the rescheduling strategy. The on-line dispatching strategy uses myopic dispatching rules, which have been adopted from flexible manufacturing...

Dispatching Vehicles Considering Uncertain Handling times at Port Container Terminals

This paper considers the problem of vehicle dispatching at port container terminals in a dynamic environment. The problem deals with the assignment of delivery orders of containers to vehicles while taking into consideration the uncertainty in the travel times of the vehicles. Thus, a real-time vehicle dispatching algorithm is proposed for adaptation to the dynamic changes in the states of the ...

Vehicle Dispatching at Seaport Container Terminals using Evolutionary Algorithms

In the last four decades the container, as an essential part of a unit-load-concept, has scored a great success in international sea freight transportation. With increasing containerization the number of seaport container terminals and competition has increased considerably. One of the success factors of a terminal is related to the time in port for container vessels and the transshipment rates...

Simulating Dispatching Strategies for Automated Container Terminals

Quay Cranes and Yard Trucks Scheduling Problem at Container Terminals

A bi-objective mathematical model is developed to simultaneously consider the quay crane and yard truck scheduling problems at container terminals. Main real-world assumptions, such as quay cranes with non-crossing constraints, quay cranes’ safety margins and precedence constraints are considered in this model. This integrated approach leads to better efficiency and productivity at container te...
