Modelling Analysis of Complex System Accident Causation Network

In order to build the complex system accident causation hierachial structure model,a new tactics was worked out for mapping a set of elements onto an accident causation factor.A complex system's safety accident causation factors at large were extracted.Structured treatment of the factors was made using the DEMATEL algorithm ameliorated by the author.In case study,bey flying safety accident causation factors for a certain air force corps of China were identified.Considered the causation factor node degree distribution under different threshold λ in reachable matrix,the causation factors hierachial structure and safety accident complex causation network based on drive force method were offered.Some pieces of advice on preventing flying safety accident were given.
