基于相关性的人机系统可靠性模型

本文在剖析人机系统中操作者行为特征的基础上,考虑到操作者行为的自适应性、自学习能力及其行为形成主因子,着重结合操作者行为的相关性-感知作用于判断决策后影响到动作,建立了人机系统中操作者行为模式,并推导出计算操作者可靠度的公式,求出了相应参数.最后进行了实例量度,同时定量辨识了行为相关性对人可靠性的制约程度,以期从人机系统可靠性角度为人机系统的优化设计提供新的依据.

A RELIABILITY MODEL OF MAN-MACHINE SYSTEM BASED ON DEPENDENCE AMONG STIMULI, ORGANISMS AND ACTIONS

High reliability and safety are the main criteria for a successful design of man machine systems (MMS). Operator's dependence is defined through response(R), as a function of stimulus (S) and organism (O). Based on the identification of operator's key performance shaping factors, an operator behaviour shaping model is proposed, incorporating an analysis of the ability of self adaptation or self study of the operator, that is able to correct errors from a critical situation. An expression for operator's reliability as some parameters is derived from the operator behavior shaping model, and such parameters are obtained from data of accidents or faults in MMS. An application of the reliability model to man machine systems with vehicle is given as a sample case. The relationship between human reliability and operator's dependence is discussed in detail.
