Abstract: | |
Route is an important factor for safe and efficient navigation of ships. In this paper, the unmanned ship navigation under complex marine meteorological conditions was analyzed.The wind, wave and ship’s own conditions were integrated considered. The unmanned ship route energy consumption and voyage time dual objective optimization model based on ideal point method was established. The meteorological and hydrological information for the route were analyzed in this model. Route optimization criteria and dual-objective programming algorithm were combined. The unfavorable influences of meteorological and hydrological were reduced. The energy consumption and voyage time of the ship were saved. And the route was found. The results showed that the great circle route can be obviously optimized in the model. The model can be applied to the weather route planning of unmanned ships in large area under complex meteorological conditions. |
