为了能够较便捷的对舰船甲板气流场进行评价，本文在数值仿真的基础上采用基于改进优劣解距离法（TOPSIS）对甲板流场进行排序。此外，评估了不同风向和风速条件下的流场，并与数值结果进行比较。结果表明，运用TOPSIS方法对SFS2舰船在不同工况下的流场质量进行优劣排序，可以得到与数值仿真相同的规律；在相同的相对风速下，关键点的侧风风速越大，流场质量越差；TOPSIS法的评估结果与研究关键点位置的选取有关。
In order to facilitate the assessment of the ship deck flow field, the Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) is applied to sort the deck flow field based on the numerical simulation. Then the flow field under different wind direction and wind speed conditions are evaluated, and it is compared with the numerical simulation analysis results. Research indicates that the TOPSIS method is used to classify the flow field quality of SFS2 ships under different working conditions,and the obtained rules are consistent with the numerical simulation results. At the same relative wind speed, when the wind speed of the key point is faster, and the quality of the flow field is worse. The evaluation results of the TOPSIS method are related to the location of the research key points.
