Qualitative Simulation and Its Application Framework in Human Reliability Analysis

Human reliability analysis in complicated industrial processes is facing to difficulties, such as insufficient knowledge utilization and simplex analytic means etc. This paper first introduces basic meanings and current research situation of human reliability analysis and qualitative simulation respectively, and then on the basis of it, considering current insufficiency of human reliability analysis methods, this paper points out the necessity to apply qualitative simulation thoughtway to carry out human reliability analysis. Furthermore, a framework of human reliability analysis based on qualitative simulation is proposed and some key issues are discussed, which lays a foundation for deeper application research of qualitative simulation in human reliability analysis in future.
