A Design Pattern Language to Assist the Design of Alarm Visualizations for Operating Control Systems
A set of incoming alarms has been registered. The human operator would like to comprehend the functional relationships between alarms and specific elements of the controlled process .
The human operator needs to explore the functional relationships between alarms and specific elements of the controlled process in order to establish the potential cause of a failure.
Map consistently the relationship between alarms and specific elements of the controlled process by using diagrams. A diagram is a visual display format that combines graphics and alphanumerics to reflect component relationships. They should contain the minimum amount of detail required to yield a meaningful pictorial representation. Controlled process components represented on lines should be identified. All flow path line origin and destination points should be identified. Flow directions should be clearly indicated by distinctive arrowheads.
Diagrams have the advantage of providing a more direct spatial mapping between the control room and the controlled process (Endsley, M. R. (2003). Designing for situation awareness: An approach to user-centered design CRC Press.)
