Problems solved by technology
[0003] The acquisition of various performance indicators requires ship model tests or actual ship tests, which is costly and takes a long test period
The existing evaluation methods are basically to evaluate the pros and cons of ship maneuverability from a single performance, but since the ship is a complex system, the maneuverability of the ship is affected by many factors, and the degree of influence of each factor on the maneuverability Different, a single evaluation index is difficult to comprehensively evaluate the maneuverability of the ship

Embodiment Construction
[0046] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below through specific embodiments in conjunction with the accompanying drawings.
[0047] The present invention provides a ship maneuverability evaluation method based on the comprehensive integration weighting method, such as figure 1 shown, including the following steps:
[0048] Step S1. Acquiring maneuverability evaluation parameters of the target ship.
[0049] Specifically, according to the provisional criteria for ship maneuverability given by IMO, the ship maneuverability evaluation parameters preferably include turning performance parameters, initial turning performance parameters, stopping performance parameters, and direction keeping and turning performance parameters.
[0050] Since the acquisition of ship maneuverability evaluation parameters currently requires ship model tests or real ship tests, the cost is high and the test p...

The invention provides a ship maneuverability evaluation method based on a comprehensive integrated weighting method. The method comprises the steps: S1, acquiring maneuverability evaluation parameters of a target ship; S2, according to a preset maneuverability evaluation parameter standard and a preset maneuverability evaluation parameter, obtaining an index for evaluating the maneuverability; S3, obtaining a target ship maneuverability comprehensive evaluation value according to the indexes used for evaluating the maneuverability and the comprehensive weight of each pre-obtained index. The acquisition of the comprehensive weight of each index comprises the following steps: acquiring the subjective weight of each index based on a G1 weighting method; obtaining an objective weight of eachindex based on an ideal point approaching method; and determining a comprehensive weight of each index according to the subjective weight of each index and the objective weight of each index based onthe sum of squares of deviations. Multiple evaluation indexes can be integrated, and a reliable means is provided for ship maneuverability evaluation.
Description
technical field [0001] The invention relates to the technical field of ship maneuverability evaluation, in particular to a ship maneuverability evaluation method based on a comprehensive integrated weighting method. Background technique [0002] With the development of the shipping industry, new ships and intelligent ships have gradually attracted widespread attention. Whether the maneuverability of ships can meet the safety requirements has always been a subject of great concern. Both the International Maritime Organization and the classification societies of various countries have put forward strict requirements on the single index of ship maneuverability. Generally, the maneuverability of a ship is evaluated from the following four aspects: the turning performance of the ship, the initial turning performance, the stopping performance, and the direction keeping and turning performance. [0003] The acquisition of various performance indicators requires ship model tests or...
