摘要:

在飞机驾驶舱等复杂人机系统中,动态变化的人与辅助系统协作关系可以使人机工作得更加协调,并提高系统整体的功能效果。为了实现需要融合多种决策信息的动态调整策略,提出基于D-S证据理论的飞行员辅助系统自动化级别动态调整的方法,首先运用
模糊隶属度函数确定证据的基本信任分配,再采用基于证据间相似系数的冲突证据合成规则融合各个证据,最后通过一个实例表明该方法有效且可靠。

Abstract:

In a complex human-machine system such as aircraft cockpit, dynamic relationship of human and assistance system collaboration enhances the harmony between human and machine, and increases the whole system performance. In
order to achieve dynamic adjustment strategy of needing to synthesize a variety of decision-making information, D-S evidence theory-based dynamic adjustment method of automation level for pilot assistance system is proposed. This method
firstly utilizes fuzzy membership function to determine basic probability assignment, and then uses similarity coefficient-based combination rule to synthesize various evidences. Examples show that the method is effective and reliable.

Key words: pilot assistance system, dynamic adjustment, D-S evidence theory, fuzzy membership function, similarity coefficient
