Ship dispatch optimization method based on channel and berth resources

Abstract

The embodiment of the invention provides a ship dispatch optimization method based on a channel and berth resources. The method comprises the steps that a processor establishes an initialization constraint, a flow conversion constraint, a time slot allocation constraint and a berth conflict solving constraint according to traffic flow characteristics of different areas of a port; a multi-target ship dispatch optimization model of the single channel is established with the goals of shortest in-port time and shortest waiting time of all ships; a multi-target genetic algorithm is designed according to the berth conflict solving constraint, the flow conversion constraint and the time slot allocation constraint; the multi-target ship dispatch optimization model is solved according to the multi-target genetic algorithm, and ship dispatch is conducted according to a solved result. By means of the ship dispatch optimization method, numerous benefit parties of the ships entering and leaving the port are coordinated, port entering and leaving of the ships are dispatched reasonably, a conflict among the ships using the channel in the process of entering and leaving the port is avoided, and the efficiency of the ships entering and leaving the port is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of ship management, in particular to a method for optimizing ship dispatching based on channel and berth resources. Background technique [0002] With the increase of large-scale ships and the number of ships, the port ships are becoming more and more crowded, and the influence of port ship dispatching efficiency on port operation efficiency is increasing. The waterway is an important channel connecting the open sea and the harbor basin. The coordinated optimization of the waterway and berth resources is an important part of the ship entry and exit operation system, which directly affects the efficiency of port ship dispatching. [0003] Such as figure 1 As shown, in the prior art, the port ship dispatching process is as follows: when entering the port, the ship sends the ship’s entry and exit plan to the VTS center 24 hours in advance, and the ship arranges an agent to apply for b...
