能见度良好时影响船舶领域的因素的重要性分析
Importance analysis of the effect factors in ship domain of good visibility
摘要
Abstract
To evaluate the significance of influencing factors in the ship domain and then reduce factors, the com-plexity of the study of ship domain was reduced. The principal component regression algorithm and the algorithm based on rough sets were selected to perform the analysis. The principal component regression algorithm and the al-gorithm based on rough sets were used to obtain the significance degrees of the factors of the ship domain. The cor-relation algorithm based on rough sets was also used to obtain the reduction set. Then, the significance of the factors was obtained by comparing the results of the two methods. Results show that the size, type, speed, encounter an-gle, density, and the level of the navigators are the most important factors. Wind, wave, flow, and visibility are less important factors, and the effect of wind, waves, and flow can be ignored.关键词
