C-HFAMF: A new way to accident analysis considering human factor

Reason´s (1990) “Swiss cheese” model of human error integrates the human error perspectives into a single unified framework. The original description of his modal was geared toward academicians rather than practitioners. The Human Factors Analysis and Classification System, HFACS (Douglas A. Wiegmann and Scott A. Shappell, 2003) was specifically developed to define the latent and active failure implicated in Reason´s “Swiss cheese” modal so it could be used as an accident investigation and analysis tool. But the hardware failure and human-machine interaction failure are not considered in HFACS. However, in complex systems, the human-machine interaction failure is the main reason for the accident, in this paper, based on the HFACS and the energy-based accident causation theory, Complex Human Factor Analysis and Classification Framework (C-HFACF) is proposed. It contains not only the human error, but also the failure to consider the human-machine interaction. The framework provides an effective way for accident analysis, which will help to effectively find out the key nodes and core events in the accident. At last, it illuminates how to apply C-HFACF to accident analysis with an actual accident.
