    Abstract: A method of minimizing car bunching at any traffic flow level allocates closely adjacent stops to a given car which is favored by a variable, readjustable distributor bonus. The estimated lost time costs of all passengers are computed for each elevator and for each hall call, these costs are reduced by a variable distributor bonus concentrating adjacent stops in one car, and a hall call is then allocated for service to that elevator which displays the lowest, reduced estimated lost time costs. In order to assure the function of this method equally at high and low traffic levels, the variable distributor bonus (Bvn) is readjusted to the traffic flow level (Va) which serves as a tracking parameter by means of a tracking function according to the relationship Bvn=Bv.F(Va) and the readjusted variable distributor bonus is defined thereby. The tracking function F(Va) is determined by one of artificial intelligence methods and expert programs. By the dependence of the distributor bonus on traffic flow, the desired small local bunching of elevator cars is an optimum for every traffic level. This method is applicable to a plurality of different allocation criteria, service requests and tracking parameters.

    Abstract: A system including a group controller for controlling the dispatching of elevator cars in a building. The group controller operates by using control parameters stored in its memory. The system records car loads of cars leaving the lobby and the time intervals between their departures and uses fuzzy logic to categorize the car loads and intervals into fuzzy sets. The system determines the lobby traffic and traffic rate using fuzzy relations among car loads, departure intervals, lobby traffic and traffic rate and the fuzzy logic rules. The group controller collects traffic data during operation. The system runs simulations off-line, after single source traffic periods, using the specified control parameter values. The system collects and analyzes performance data to identify significant deviations from acceptable performances. New sets of control parameters are selected using appropriate specified rules. The process of simulation and learning new values of control parameters are repeated until acceptable performance is achieved. The selected parameters are used in system operation. The group controller repeats this process of simulation and learning the parameters periodically.

    Abstract: An elevator group control system is provided which stably keeps cage's position in temporally equal interval condition over a long period of time.
    The present invention provides a system comprising: reference route generating means, which for each elevator, generates a reference route which the elevator should follow with respect to the time axis and position axis; and assignment means which selects an elevator for assignment to a generated hall call so as to make the actual trajectory of each elevator closer to its reference route.
    Since reference routes which guides the cage's trajectory into temporally equal interval condition are generated and car assignment is executed so as to make the respective cages follow their reference routes, it is possible to allow the cages to settle in temporally equal interval condition over a long period of time.

    Abstract: A system for controlling elevator cars in a building having a plurality of floors includes a group controller for controlling operation of the elevator cars. The group controller predicts lobby single source traffic for determined periods. When the predicted traffic is below a certain limit, cars are assigned to a lobby hall call on demand after hall call registration. When the predicted traffic is above a certain limit, cars are assigned to the lobby hall call at intervals. Accordingly, car assignment is scheduled at those intervals. The schedule interval is varied based on predicted traffic and predicted round trip time of the cars. The cars are assigned to hall calls if they arrive within a schedule window. The schedule window comprises a lower and an upper tolerance that are selected around a scheduled time.
