Abstract

In order to address safety problems of social technology system which are more and more prominent during its continuous development, a new safety model that adapts to complex system and features general applicability is required to be developed. Firstly, by using system analysis method, factor classification method and system level method, a nested model was constructed, which was composed of micro-meso-macro three scale systems (3MS) and mission-man-machine-material-management-environment-information-culture (5Meic) 8 factors. Secondly, its characteristics and application methods were described. Thirdly, this model was applied in construction of a safety management model of high-speed rail operation system considering China's rapid development in this field and potential outstanding risks in its operation. Finally, mechanism and necessity of social forces participating in safety governance of high-speed rail were demonstrated, and the model was verified. The results show that proposed model can be used to guide safety micro-matching, meso-system matching and macro-matching of the elements in micro- meso-system and macro-system, so as to achieve safety objectives of complex systems. It can also be utilized in safety analysis and evaluation of various scales and scenarios, as well as classification of security factors and system construction. © 2020 China Safety Science Journal
