  • Patent number: 11577933
    Abstract: An evacuation strategy support system using an occupant evacuation elevator (OEE) capable of supporting an evacuation strategy so that information on a number of occupants is recognized by real-time occupant monitoring and thus occupants on each floor may use stairs and the occupant evacuation elevator to safely and quickly evacuate when a disaster situation occurs in a skyscraper and thus the occupants use the occupant evacuation elevator to evacuate, capable of monitoring occupant information on each floor in real time and supporting calculation of an evacuation capacity of the occupant evacuation elevator to establish an evacuation strategy to allow safe evacuation and early reaction in an overall skyscraper to be performed, and capable of optimizing the calculation of the evacuation capacity of the occupant evacuation elevator applicable to an initial stage of a design of the skyscraper, and a method thereof are provided.
