Causation Analysis of Complex System Safety Accident Based on Brittle Structure Collapse Theory

In order to explore the inherent safety accident causation of complex system, offer the effective measures for controlling the safety accident, the complex system brittle structure inevitability collapse trend was analyzed, indicated that the system structure of complex system is a brittle structure with the latent collapse trend. The mathematic description of the safety condition and chain collapse of the complex system was gained by the analysis of the brittle structure collapse process, offered the method for control the collapse of the safety-critical system, which established the foundation for further complex system safety study.
