为充分认识安全科学研究中的安全事件本质,基于安全结构理论,进行安全事件内涵的数学表达研究。定义安全事件的本质因素,提出通过因素约简、因素集完备性检验和因素独立性检验获取安全事件本质因素集的处理算法;从逻辑学角度给出安全事件的内涵,并根据安全事件本质因素的表现外延隶属函数,给出安全事件内涵数学表达的算法。研究表明:所有决定安全事件发生的、独立且完备的因素组成安全事件的本质因素集,全体本质因素的属性组合为安全事件的内涵;本质因素状态集的笛卡尔乘积集构成安全事件的因素空间,该空间是承载安全事件内涵的完备的数学逻辑分析框架。
In order to fully understand the nature of safety events in safety science research and to study the mathematical expression of safety events based on the theory of safety structure. Define the essential factors of security incidents, and propose a processing algorithm to obtain the set of essential factors of security incidents through factor reduction, completeness test of factor sets and factor independence test; provide the connotation of security incidents from the perspective of logic, and according to the essential factors of security incidents The performance of the extension of membership function, given the connotation of the safety event mathematical expression algorithm. The research shows that all the independent and complete factors that determine the occurrence of security events constitute the essential factor set of security events, and the combination of all the essential factors is the connotation of security events. The Cartesian product of the essential factor states sets the factor space of security events This space is a complete mathematical logic analysis framework that carries the connotation of security events.
