Analysis of safety assessment model for the Aviation Enterprises

According to the constituent elements of enterprises accident system, the in-depth analysis of aviation enterprise security systems is made. Based on SHEL model, through introducing artificial neural network approach and selecting the feed-forward BP network model, the network structure is established. The enterprise accident systems are divided into four subsystems of Life element-hardware subsystem, Life element -software subsystem, Life element -environment subsystem, Life element - Life element subsystem and the total accident integrated assessment system. Then taking an airline enterprise (named "Q") as an example to be trained and tested. The fitting quantitative analysis were made and the quantify results and the applicability of the model are obtained. The empirical results show that the research can provide a theoretical basis and decision support for enterprise managers to improve and perfect safety management
