摘要：The Fully Automated Operation (FAO) system is the new developing trend in the railway domain in China. However, FAO poses an operational risk because the operator lacks the operational experiences of new system so that it is difficult to determine fault property and process of revenue service. The paper attempts to explore the nature of changing mechanisms of organization integrated with human factors as a process and to single out the latent causes of failure in FAO system. In order to analyze the organization's risk, a Viable System Model (VSM) is adopted to explore the control flaws of FAO system's organization from the Systems Theoretic Accident Model and Processes (STAMP). Meanwhile, with respect to detecting the causal relationship and revealing deeper reasons of the control flaws of organization, we propose a set of dynamic archetypes of pattern of organizational breakdown based on the system dynamics. The recursion of constrains and process inherited by STAMP provides the feasibility and vulnerability over prediction and recovery process of system operation and management. The hybrid system dynamics modeling method, combining VSM and system dynamics, can help to predict the organization risks, monitor the drifting safety boundary, analyze the boot cause in accident, and support the recovery of inappropriate feedback of organization in FAO system
