Abstract

The invention discloses an ECDIS-based airline automatic design system and a construction method thereof. Recommended airlines and an airline information database are established by adopting a spatialdatabase management system; by constructing a weighted airline network graph, an optimal airline is solved in combination with the recommended airlines by adopting a Dijkstra algorithm; Matlab is used for performing modeling simulation; and different ships are subjected to an airline optimization simulation experiment. Based on the recommended airlines, the optimal airline is obtained by utilizing artificial intelligence and graph theory methods. According to the ECDIS-based intelligent airline automatic design system, a planned airline can be automatically generated; an extremely convenientairline information query function is realized; the workload of drivers is reduced to the maximum extent; and the system is of important practical significance for ensuring the ship navigation safetyand reducing the ship navigation operation cost.

Description

technical field [0001] The invention relates to the field of route design, in particular to an ECDIS-based route automatic design system and a construction method thereof. Background technique [0002] In order to ensure the safety of ships navigating at sea, the first task is to formulate a correct and reasonable route, which is a very important and very complicated task in navigation. Whether this work is done well or not will directly affect the safety of the ship's navigation at sea, and will eventually affect the operating profit of the ship. The basic principles to be followed in formulating a correct and reasonable route are: it is both safe and economical. [0003] The traditional route design is quite cumbersome and complicated, mainly including verifying the port name, determining the timing of entering and leaving the port, collecting and consulting the information about the route, preliminary (draft) drawing route, determining the route, pre-drawing the planned ...

AI Technical Summary

Problems solved by technology

Its obvious disadvantages are: it cannot ensure that the obtained path must be optimal, and it is a lossy algorithm, because the local optimum is not equal to the global optimum

None of the existing algorithms effectively considers the dynamic marine environment information, and this dynamic information affects the quality of the optimal solution in a scientific sense, and is of great significance to ship navigation in practical applications

[0016] Third, most of the existing route planning algorithms are researched on planning problems in a small area and in a simple environment, and are not suitable for a large-scale ocean environment with relatively sparse obstacles

Scholars have exploratoryly used intelligent algorithms for the optimal design of flight routes, but due to too many empirical parameters required, the evolution rate is not easy to control, and it is difficult to meet the real-time requirements of flight planning.
