Hybrid dynamic scheduling method used for port container truck

Abstract

The invention discloses a hybrid dynamic scheduling method used for a port container truck. The hybrid dynamic scheduling method comprises the following steps: the container truck reloads containers on an import ship and unloads the containers in on export ship; a dynamic scheduling model of the container truck is established by taking total operating time as a standard, and the dynamic scheduling model is established on the premise of a known gantry crane loading plan and a known gantry unloading plan; and on the basis of shortest total operating time, an operation path of each container truck is dynamically optimized. A dynamic scheduling mode is adopted to improve the use ratio of the container truck, the no-load driving distance of container truck transportation is reduced, a next operation task is assigned according to principles including path optimization, instruction optimization and the like, a container truck transportation process is subjected to comprehensive scheduling, the container truck is selected in multiple tasks according to the selection of path distances at any moment, and a container truck service object is dynamically collocated with the operation plane of the whole wharf.

Description

technical field [0001] The invention relates to the field of port container management, in particular to a hybrid dynamic scheduling method for port container trucks. Background technique [0002] With the development of the economy, modern ports are playing an increasingly important role in the global comprehensive transportation system. They are not only the starting point and end point of container ocean transportation, but also the transit hub for container transshipment between land transportation and sea transportation. The transportation method of containers is convenient and cheap, which greatly improves the efficiency of logistics. Nowadays, international trade transportation, especially sea transportation, mostly adopts the form of containers. At present, in most container terminals, nearly 50% of the routes of container trucks are empty, and the utilization rate is not high. In order to ensure the operation of the quay crane, when the quay crane is far away from ...

AI Technical Summary

Problems solved by technology

It mainly includes the independent loading and unloading operation mode, which mainly means that the container truck carries an imported container at berth A and transports it to the import container yard, and then returns to the berth empty-loaded to unload another imported container; Load a container at the yard and transport it to berth B, and then return to the yard empty-loaded to load another export container. This operation mode makes the empty-load rate of the container truck reach about 50%, and the distance traveled by the container truck to complete a certain amount of tasks will also increase. A lot, increasing the empty driving distance of container trucks. With the development of container terminals, the throughput of terminals is increasing, and the number of container trucks required is also increasing, which will cause traffic congestion, increase fuel costs, and the number of drivers. increase etc.
