A dynamic collaborative scheduling method for double-yard bridges in container yards

Abstract

The invention discloses a method for dynamic collaborative dispatching of double yard bridges in a container yard, which includes step 1, using container yard operation simulation to simulate and learn the designed Q value table, and obtaining the Q value table after the simulation study; step 2, using The learned Q value table and action selection strategy dynamically generate the action instructions of the yard bridge, and the yard bridge selects tasks to carry out operations according to the action instructions. The method improves the operation efficiency of stacking and retrieving boxes in the storage yard, and reduces the interference of double yard bridges and the waiting time of vehicles.

Description

technical field

[0001] The invention belongs to the technical field of automobiles and transportation, and in particular relates to a dynamic coordinated scheduling method for double-yard bridges in a container yard. Background technique

[0002] With the globalization of the economy and the development of international trade, the volume of container freight continues to grow. Container ships are constantly becoming larger. In recent years, many container ships with more than 20,000 TEUs have been put into use. The increase in container throughput and the enlargement of ships require container terminals and yards to have greater throughput capacity and higher operating efficiency. The storage yard is the core operation area of ​​the container terminal and the station, and its main loading and unloading mechanical equipment is the container yard gantry bridge crane (abbreviated as the yard bridge). The loading and unloading turnaround time of ships and vehicles at docks and...
