Method for analysis of production plant disturbance propagations applicable to any continuous or batch process in industrial facilities ranging from chemical, pharmaceutical, nuclear, to oil & gas business industries, using a computing device with a data memory linked to the control system of the plant, characterized in that • a two-dimensional digraph matrix describing at least a disturbed part of a disturbed plant topology is event-triggered dynamically generated and stored within the data memory of the computing device when a disturbance in the plant is detected by the control system of the plant, • the columns of the digraph matrix represent plant components organized by topological connectivity and wherein the rows represent specific interrelated propagation carriers, • at least two directed disturbance propagation paths from a propagation carrier at a disturbed plant component to a disturbed carrier at a subsequent plant component are pre-determined which each define a sequence of node-elements within the digraph matrix, and comprising the following steps: • providing a look-up table with respective node-element values describing the likelihood, that a given propagation carrier continues its propagation towards the next connected plant component, • multiplying the respective likelihood values of the node-elements of each sequence so that an overall likelihood value for each sequence is derived therefrom, • ranking the sequences according to their overall likelihood, • providing the ranking of the sequences respectively the ranking of the propagation path to a user interface, wherein providing the ranking of the sequences respectively the ranking of the propagation path to the user interface provides an additional measure to assist an operator of the plant to handle a respective disturbance and provides automated fault diagnosis and alarm management. • a two-dimensional digraph matrix describing at least a disturbed part of a disturbed plant topology is event-triggered dynamically generated and stored within the data memory of the computing device when a disturbance in the plant is detected by the control system of the plant, • the columns of the digraph matrix represent plant components organized by topological connectivity and wherein the rows represent specific interrelated propagation carriers, • at least two directed disturbance propagation paths from a propagation carrier at a disturbed plant component to a disturbed carrier at a subsequent plant component are pre-determined which each define a sequence of node-elements within the digraph matrix, and • providing a look-up table with respective node-element values describing the likelihood, that a given propagation carrier continues its propagation towards the next connected plant component, • multiplying the respective likelihood values of the node-elements of each sequence so that an overall likelihood value for each sequence is derived therefrom, • ranking the sequences according to their overall likelihood, • providing the ranking of the sequences respectively the ranking of the propagation path to a user interface, wherein providing the ranking of the sequences respectively the ranking of the propagation path to the user interface provides an additional measure to assist an operator of the plant to handle a respective disturbance and provides automated fault diagnosis and alarm management.
