Systematic layout planning in human-sytem interface An evaluation of alarm displays with spatial proximity for accidents diagnosis of advanced nuclear power plant

To ensure safety in nuclear power plants, this study investigated the interface design of a digital alarm system by analyzing the cognitive model of operating information. This study focused on the layout planning of alarm windows and followed proximity compatibility principle and nuclear human-system interface design review guidelines to improve the human-system interface. This study adopt systematic layout planning to modify the design of alarm windows. The time of alarm handling, and situation awareness, as well as human reliability were evaluated to compare the original layout with the improved one. In the end, according to the results of the comparison, an alternative alarm window layout human-system interface, which fits operators´ cognitive models, is suggested.
