Abstract: High reliability and safety are the main criteria for a successful design of man-machine sys?tems (MMS). Operator’s dependence is defined through response(R), as a function of stimulus (S) and organism (U). Based on the identification of operator’s key performance shaping factors, an operator be?haviour 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 operator9 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 depen?dence is discussed m detail.
