功能分配是人机设计过程中一个必然阶段,因为合适的功能分配能够让整个系统更加有效更加可靠。因此,我们主要对人机系统的人机功能分配问题进行研究,根据人、机的内在特征,分析了人、机各自的能力优势并进行了比较。针对实际过程中决策属性值具有高度不确定性的特点,将ULMADM(不确定语言多属性决策)方法引入功能分配过程,采用不确定扩展加权算术平均(UEWAA)算子确定功能自动化等级范围,基于UEWAA算子和不确定语言混合集结(ULHA)算子相结合的多属性群决策算法最终确定驾驶舱人机功能分配的自动化等级。最后,以民机驾驶舱“故障诊断”功能分配为例进行了计算,验证了所提出的功能分配方法的可行性和有效性。
Function allocation is a necessary stage in the human-machine design process, because the appropriate function allocation can make the whole system more effective and more reliable. Therefore, we mainly study the distribution of man-machine functions in the man-machine system. According to the intrinsic characteristics of people and machines, we analyze the respective advantages of people and machines and compare them. In view of the high uncertainty of decision attribute values in practical process, ULMADM (Uncertainty Multi-attribute Decision Making) method is introduced into the function assignment process, UEWAA operator is used to determine the scope of function automation grade, A multi-attribute group decision algorithm based on UEWAA operator and ULHA operator determines the automation level of cockpit man-machine function assignment. Finally, taking the example of the cockpit cockpit “fault diagnosis ” function assignment as an example, the feasibility and validity of the proposed method are validated.
