1. A system for action determination, comprising:
an input unit;
a processor; and
an output unit,
wherein the input unit is configured to provide the processor with information relating to a plurality of past actions over a period of time associated with an operation of an industrial process, wherein the information relating to the plurality of past actions comprises one or more operator actions,
wherein the input unit is configured to provide the processor with information relating to a plurality of past process events over the time period associated with the operation of the industrial process, wherein the information relating to the plurality of past process events comprises a plurality of alarms, wherein the processor is configured to ignore one or more alarms that appear uniformly over the time period, and wherein the processor is configured to cluster multiple identical alarms within a defined short time interval relative to the period of time into a single alarm,
wherein the input unit is configured to provide the processor with information relating to a new process event,
wherein the processor is configured to determine a correlation between the plurality of past actions with the past process events, wherein determination of the correlation comprises a statistical analysis to detect a relationship between alarms and actions, wherein determination of the correlation comprises determination of an action to alarm matrix, and wherein determination of the correlation comprises a statistical inversion of the action to alarm matrix to determine a plurality of rules and associated probabilities,
wherein the processor is configured to apply a principal component analysis to filter most significant rules, and wherein filtering of the most significant rules comprises removal of one or more rules that correspond to an alarm that triggers a significantly high number of rules,
wherein the processor is configured to determine at least one recommended action from the information relating to the new process event, the determination is based on utilization of the determined correlation and the most significant rules ordered by their associated probabilities,
wherein the output unit is configured to output the at least one recommended actions,
wherein the processor is configured to perform automated operation of the industrial process based on the at least one recommended action, and
wherein performing the automated operation of the industrial process based on the at least one recommended action comprises closing and/or opening of a valve.
