Liquid tank stowage method and system for intelligent ship

Abstract

The invention provides a liquid tank stowage method and system for an intelligent ship, which comprises the following steps of: acquiring a longitudinal inclination value, a transverse inclination value, an initial stability height value and total longitudinal strength of a ship in an assembling process of a liquid tank, and establishing a mathematical model; collecting initial stowage working conditions of the plurality of liquid tanks, and comparing the initial stowage working conditions with target stowage working conditions of the liquid tanks to determine a to-be-stowage liquid tank; encoding the liquid tank to be stocked, randomly generating a plurality of encoding sequences with priorities as stocked schemes by the encoding, and forming an initial scheme group by the plurality of encoding sequences; performing loop iteration operation on the initial scheme group, and obtaining an optimal coding sequence as a final stowage scheme. According to the invention, optimization calculation is carried out on the liquid tank stowage process through an improved genetic algorithm; the problem that liquid tank stowage calculation depends on human experience is solved, the loading and unloading efficiency of a ship is improved, and meanwhile, the initial stability height and the total longitudinal strength constraint of the ship are met by reducing the accumulated inclination amount in the liquid tank stowage process so as to guarantee the stability and safety of the ship.

Description

Technical field [0001] The invention relates to the field of ship tank loading, in particular to a tank loading method and system for smart ships. Background technique [0002] In the prior art, for the problem of cargo or tank stowage, the stowage is mainly carried out by humans. Usually, the chief officer makes a stowage plan in advance based on his own experience and actual situation, which wastes time and manpower costs, and at the same time involves a lot of In a tank, the stowage process can include loading and unloading. In the process of loading and unloading, if the operation is improper, the ship may tilt significantly, and even the strength of the hull is damaged. It is related to the safety of the ship. Therefore, the stowage of the tank The order has a real necessity. Summary of the invention [0003] The present invention provides a tank stowage method for smart ships to overcome the above technical problems. [0004] The invention provides a tank stowage method for ...

[0002] In the prior art, for the stowage problem of the cargo tank or liquid tank, the stowage is mainly carried out manually. Usually, the first officer prepares the stowage plan in advance based on his own experience and the actual situation, which wastes time and labor costs. The stowage process can include loading and unloading. In the process of loading and unloading, if the operation is improper, the ship may tilt obviously, and even the strength of the hull will be damaged, which is related to the safety of the ship. Therefore, the stowage of the liquid tank order has a real necessity
