Abstract

The invention discloses a ship field-based fixed-line system water area navigation risk assessment method. The method comprises the steps of determining the ship navigation risk influence factors in afixed-line system water area and an assessment set of a navigation risk degree; determining the weight of the ship navigation risk influence factor by adopting a fuzzy analytic hierarchy process; optimizing the navigation risk influence factor by adopting a ship domain model; carrying out single factor evaluation on the optimized navigation risk influence factor to determine the membership degreeof the navigation risk influence factor to the evaluation set; according to the optimized navigation risk influence factor and the membership degree, determining the overall navigation risk degree ofthe ship in a fixed line system water area; and changing the route of the ship in the fixed line system water area according to the navigation risk degree. According to the invention, the level evaluation of the ship navigation risk is realized, and the traffic management personnel and the ship drivers can conveniently master the navigation risk in the water area.

Description

technical field [0001] The invention relates to the technical field of ship navigation, in particular to a method for assessing the risk of navigation in waters with a route-setting system based on the ship field. Background technique [0002] Ship routing navigation, also known as "ship routing". It is an important part of vessel traffic management. The routes, routes or traffic lanes that designated ships should follow or adopt when navigating in certain areas of the sea are stipulated or recommended by the shore-based department by law. Its main form is the traffic separation system, the purpose of which is to improve the safety of navigation in areas where ships converge and have a high density of traffic, where the movement of ships is restricted, navigation obstacles exist, water depth is limited, or weather conditions are poor. [0003] The current way of judging the risk of ship navigation is mostly based on a single ship, the crew or the automatic collision avoida...
