Wargaming system is an effective method for emergency management. The evaluation methods are the important parts of the system. First, the essential features and principles of wargaming system are explained. Then, the evaluation methods of wargaming system are analyzed, and four main types of evaluation methods are described in detail, such as the movement type, position type, effect type and impression...
Accident model,i.e. accident-causing theory, that is a main component of Principium of Safety, is an important part of accident theory. It avoids concrete characteristic of hazard source and content and mode of accident temporarily. Instead, abstractly thinking of person, machine, goods and environment in system, revealed accident causes, processes and results in nature.After many researches, it appears...
This paper proposes the concept of accident rehearsal and defines its connotation based on the philosophy of the rehearsal technique. The method of accident rehearsal based on Object-Oriented Fuzzy Petri Net proposed in this paper reflects the dynamic behavior of the system and the development of the system state through state transition. It can describe the differences, the relationships and the...
Accident is always the result of a variety of influence factors which are in dynamic operational processes and mutual coupling. Because there is still lack of technical approaches supporting the study of accident analysis by the view of multi-factor coupling and accident's dynamic development, a new model of multi-factor coupling event chain based on Petri Nets is presented in this paper. By analyzing...
An accident model which is used to describe accident causation and evolvement is the foundation for system safety research. Most traditional accident models just research into accident causation, and can not effectively conduct hazard analysis. The traditional hazard analysis methods are incomplete and can not implement comprehensive hazard analysis of a dynamic operational process. To address this...
