提出人-硬件在环仿真框架，结合STAMP模型，在油气实验平台测试操作员行为对系统性能的影响，为复杂社会技术系统的韧性评估提供定量方法。
Modern industrial systems require updated safety management approaches, as the tight interplay between cyber-physical, human, and organizational factors has driven their processes toward increasing complexity. In addition to dealing with known risks, managing system resilience acquires great value to address complex behaviours pragmatically. This manuscript starts from the System-Theoretic Accident Model and Processes (STAMP) as a modelling initiative for such complexity. The STAMP can be natively integrated with simulation-based approaches, which however fail to realistically represent human behaviours and their influence on the system performance. To overcome this limitation, this research proposes a Human-Hardware-in-the-Loop (HHIL) modelling and simulation framework aimed at supporting a more realistic and comprehensive assessment of systemic resilience. The approach is tested on an experimental oil and gas plant experiencing cyber-attacks, where two personas of operators (experts and novices) work. The obtained results provide a means to quantitatively assess how variations in operators’ behaviours impact the overall system performance, offering insights into how resilience should be understood and implemented in complex socio-technical systems at large.
