    Abstract: A method of operating a building elevator system within a building having a plurality of floors is provided. The method including: controlling a first elevator group composed of one or more elevator systems configured to serve a plurality of floors within a first sector, the one or more elevator systems in the first elevator group further include a first elevator car; controlling a second elevator group composed of one or more elevator systems configured to serve a plurality of floors within a second sector, the one or more elevator systems in the second elevator group further include a second elevator car; monitoring usage of the first elevator group and second elevator group; and reassigning at least one of the one or more elevator systems of the second elevator group to the first elevator group in response to usage of the first elevator group and usage of the second elevator group.

    Abstract: The present invention provides a method of predictively maintaining an elevator driving unit which distinguishes between a condition when moving an elevator upward and a condition when moving the elevator downward, collects driving information of the driving unit (information on a change over time in current values) in a normal state, collects driving information of the driving unit before the occurrence of breakdown, sets critical levels based on the collected information, detects in real time an abnormal symptom of the driving unit by comparing the driving information of the driving unit, which is collected in real time, with the set critical level, and then performs stable predictive maintenance of the elevator driving unit, thereby efficiently preventing a safety accident of the elevator caused by a breakdown of the elevator driving unit.

    Abstract: A method schedules elevator cars in a group elevator system in a building by first generating a set of probability distributions for arrivals of future passengers at any floor of the building, wherein the set of probability distributions are characterized by probabilistic variables that specify arrival information of the future passengers, wherein the arrival information includes a probability of service requests by the future passengers and a probability of possible times of the service requests. A schedule for the elevator cars is based on the set of probabilistic distribution. Then, the schedule is provided to a controller of the group elevator system to move the elevator cars according to the schedule.

    Abstract: An intelligent destination elevator control system streamlines the efficiency and control of destination elevators. The system monitors a building's population and predicts elevator traffic conditions. The system may monitor attributes of the destination elevators. Based on the monitored data, the system may generate a data structure that renders time-tables and target elevator service quality parameters that may control the destination elevators.

    Abstract: The present invention discloses a method and a system for modernizing at least one elevator group, which comprises a plurality of elevators, a group control that controls the elevator group as well as call-giving appliances connected to the group control via the landing appliance bus. According to the solution a new group control, new call-giving appliances for the floor levels and also a new landing call bus are installed in the elevator group; a new group control is connected to the pushbutton interface of the old call-giving appliances for transmitting calls given by passengers from the new group control to the old group control. The elevator calls given by passengers are divided between the modernized subgroup and at least one unmodernized subgroup on the basis of the given selection criterion, and a call addressed to the modernized subgroup is allocated in the new group control to the modernized elevators or a call addressed to the unmodernized subgroup is transmitted via the pushbutton interface to the unmodernized subgroup.
