    Interface PlantOperatingStatesAnalysis

    Interface representing plant operating state analysis.

    This is the main container interface that brings together all aspects of the Plant Operating States Analysis. It implements multiple High-Level Requirements (HLRs) and their Supporting Requirements (SRs).
