Abstract
A computer implemented method for facilitating the root cause analysis of an event through spatial and pattern recognition. Alarms can be graphically represented in an alarm summary screen by individual colored rectangles with different luminance and patterns and are organized into categories, which are used to form logical alarm clusters that provide spatial advantage, wherein the size and color of the rectangle defines its priority and precedence. The summary screen also provides operators with strong visual cues, a play forward feature to project how alarms might evolve if particular actions are taken and a play backward feature that can replay the sequence of alarms.
