Dynamic Scheduling Method of Ground Lock Station Considering Art Pre- and Post-buffer

Abstract

The invention provides a dynamic scheduling method for the ground locking station considering the ART front and rear buffers. According to the dynamic changes of the lock station and the buffer zone, the ART enters the lock station and the buffer zone when unloading the ship and entering the lock station and the buffer zone respectively when loading the ship. Scheduling: When unloading, according to the first-come, first-served and nearest allocation strategy, the ART is allocated a lock station; when loading, according to the operation efficiency of the lock station, the estimated time of the ART arriving at the quay crane, the logical relationship of container loading, the real-time position of the ART, The distance between the front buffer zone and the ART, and the estimated remaining travel time between the lock station and the front buffer zone. Allocate the lock station and the front buffer zone for the ART. At the same time, when the system receives the completion information of the ART unlocking operation of the ship loaded in the lock station, it will automatically control the unlocking operation. The completed ART goes into the free back buffer. The invention can improve the utilization rate of the lock station and the quay crane, and relieve the congestion phenomenon of the lock station and the quay crane operation lane.

Description

technical field [0001] The invention belongs to the technical field of port facilities, and in particular relates to a ground lock station dynamic scheduling method considering ART pre- and post-buffering. Background technique [0002] In recent years, the port industry, especially the port industry involving container transportation, has continuously improved the efficiency and intelligence of equipment scheduling. However, in the existing container ports, the scheduling scheme of the lock station and the front and rear buffers is relatively fixed, and it relies heavily on a single scheduling strategy, which often leads to low utilization of the lock station and buffer area, and congestion in the quay crane and the lock station operation area. Seriously reduce the efficiency of port operations. At the same time, the dynamic change of equipment status is not considered in the dispatching strategy, and only a single fixed dispatching scheme result is followed, resulting in u...

AI Technical Summary

Problems solved by technology

In the existing container ports, the scheduling schemes of the lock station and the front and rear buffer zones are relatively fixed, and rely heavily on a single scheduling strategy, which often leads to low utilization of the lock station and buffer zone, and congestion in the quayside crane and lock station operation area. Seriously reduce the efficiency of port operations

At the same time, dynamic changes in equipment status are not considered in the scheduling strategy, and only a single fixed scheduling plan is followed, resulting in unsatisfactory scheduling results and ultimately resulting in low port efficiency.

[0003] As the loading and unloading workload increases, the time cost of traditional scheduling schemes also increases accordingly
