A novel analysis method for systems engineering based on wargaming technology is proposed. First, the essential factors and procedures of wargaming are introduced. Then, the systems engineering method based on wargaming is analyzed. At last, the systems modeling, simulating, and analyzing procedure is described in details by illustrating a living example. The characteristics and advantages of this...
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...
The characters of fixed block system and moving block system are introduced . Based on the concept of moving block, the way to calculate the subway trainpsilas time interval is proposed after the compare with the fixed block and quasi-moving block. The formulation for the time interval under three signals are introduced, the simulation and the analysis are done.
