摘要:

针对固定翼飞行器在可达区域内最佳应急着陆场选择问题, 通过构建普适性的指标体系,将上述问题转化为多属性评价问题, 并提出一种熵权灰色理想解逼近(technique for order preference by similarity to an ideal solution, TOPSIS)法对问题加以解决。从天气情况、着陆场特性、空域拥堵程度和地面保障能力4个方面进行分析, 细化为13个评价指标, 构建了应急着陆场评价指标体系。在传统TOPSIS的基础上, 分别使用熵权法和灰色关联度对权重计算和距离测度进行改进, 解决了传统方法依赖评价专家的主观赋权和采用欧式距离导致的无法评判优劣的问题。通过仿真对比, 体现了所提方法在权重确定方面的客观性和距离测度方面的准确性, 能够为飞行器应急着陆场的选择提供依据。

Abstract:

Aiming at the selection of the optimal emergency landing site in the reachable area of fixed-wing aircraft, the problem above is transformed into a multi-attribute evaluation problem by constructing a universal index system, and an entropy weight grey technique for order preference by similarity to an ideal solution(TOPSIS) is proposed to solve it. The evaluation index system of emergency landing site is constructed based on the analysis of weather conditions, landing site characteristics, airspace congestion degree and ground support capacity. On the basis of the TOPSIS, the entropy weight method and the grey correlation degree are used to improve the weight calculation and the distance measurement respectively, which solves the problems that the traditional method relies on the subjective weighting of the evaluation experts and cannot judge the advantages and disadvantages by using the Euclidean metric. The simulation results show that the proposed method is objective in weight determination and accurate in distance measurement, which can provide basis for the selection of aircraft emergency landing site.

Key words: emergency landing, index system, technique for order preference by similarity to an ideal solution (TOPSIS), entropy weight method, grey correlation degree
