【Abstract】 This paper briefly presents the actuality of human reliability research, analyzes the relationship of operators’ pressure to their working effectiveness and discusses the characteristics of operators’ pressure. A mathematical six mode Markov model which quantitatively predicts human reliability under fluctuating pressure is developed. It is concluded that mean time of human error is reduced quickly when the constant human error rates under low and high pressure are increased. According to the theory of human engineering, this paper presents three factors remarkably effecting operators’ pressure, i.e. operating spaces and equipments, working environments, operating procedure. These factors should be given comprehensive consideration to apply moderate pressure upon operators in order to minimize the human error rates.更多还原
