Study on quantitative equilibrium model of human factor risk control

Controlling human factor risk is an important mean to reduce accident. The mechanism of human error behavior is analyzed in the paper, it indicates that human error is mainly caused by external conditions and the individual´s own psychological, physical and other conditions; the method for establishing the mode of human factors risk control is proposed based on Newton´s Third Law, the paper points that in order not to make accident, human factor risk mitigation capacity in a safety management must be equal to or more than human factor initial risk lever; On this basis, the step and method for quantifying human factor risk mitigation capacity and human factor initial risk level is introduced; Finally, quantitative equilibrium model of human factor risk control is obtained. It is a new attempt to predict the final size of human factor risk by integrating the initial risk data and risk mitigation data in the field of safety and risk management.
