Abstract

An embodiment of the invention provides a two-way navigable port ship scheduling optimization method. The method comprises the following steps of according to a one / two-way navigable conversion characteristic, establishing a mode conversion constraint; according to continuity of harbor operation of a ship, establishing a continuity constraint; according to a vertical ship safety spacing and a transverse safety spacing, establishing a safety constraint; according to the mode conversion constraint, the continuity constraint and the safety constraint, establishing a multi-objective genetic model; initializing the multi-objective genetic model, wherein chromosome corresponding to the multi-objective genetic model after decoding is combined with the continuity constraint and the safety constraint so as to obtain a ship scheduling scheme; the scheduling scheme comprises ship scheduling beginning time, time of sailing to other key positions, a speed after adjustment and time of waiting for putting in or leaving. By using the method of the invention, two-way navigable port ship scheduling is realized and efficiency of the two-way navigable port ship scheduling is increased.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of port vessel dispatching, and in particular to a two-way navigable port ship dispatching optimization method. Background technique [0002] In recent years, with the development of the transportation industry, the density of ship traffic has increased, and sea traffic has become increasingly congested. In order to adapt to the changes, various domestic ports have either increased the construction scale or continuously widened the waterways, gradually developing from one-way waterways to two-way waterways, or even Compound channel. Compared with the expansion of the channel scale, the optimization of ship traffic organization is also an effective means to improve the efficiency of ships entering and leaving ports. [0003] Traditional ship dispatching management technical solutions are all done manually. The dispatching operation involves departments including the unloading fleet,...
