Abstract

Control systems faults in a process plant means that its goals cannot be achieved. This situation leads to alarms firing, emergency shutdown or even accidents. In order to avoid these consequences an analysis of both the process and the control system must be performed. However, the complexity of both systems together with their interactions makes this analysis a hard task. The D-higraph functional modeling methodology is presented, this technique integrates functional and structural information ...
