Abstract: A method of determining a risk state for a complex industrial process includes graphically depicting a process flow diagram on a graphical user interface with a computer system, the process flow diagram including one or more side streams of the complex industrial process, monitoring one or more process parameters of the one or more side streams, and calculating a risk state for each side stream with the computer system based on the one or more process parameters. The risk state of each side stream is then graphically depicted on the process flow diagram by assigning a probability indicator to each side stream based on the risk state calculated by the computer system, wherein the probability indicator comprises a graphical output recognizable by a user and corresponding to a predetermined scale of failure probability.
