本文从熵增加的观点描述了事故的本质,剖析了人机系统的实质与特性,提出了风险熵与事故势的概念,给出了计算风险熵与故事势的方法.结果表明,系统具有二重性.在系统运行期间,系统具有封闭体系的特性;在休整期间.系统具有开放体系的特性.事故是运行系统的必然发展趋势,是一种自发过程,是运行系统的固有属性.由于在系统熵增的过程中信息与能量的交换,所以可以把事故定义为系统熵增加的结果.避免事故发生的原理是不断向系统输入信息或负熵以抵消系统内部的熵增加.
This paper describes the nature of the accident from the perspective of increased entropy, analyzes the essence and characteristics of the human-machine system, puts forward the concept of risk entropy and incident potential, and gives a method to calculate the risk entropy and story potential.The results show that the system has duality During the operation of the system, the system has the characteristics of a closed system; During the rest period, the system has the characteristics of an open system.It is an inevitable trend of the operation system, an autonomous process and an intrinsic property of the operating system.As the system entropy Therefore, the accident can be defined as the result of increased system entropy.The principle of avoiding accidents is to continuously input information or negative entropy to the system to counteract the increase of entropy in the system.
