Abstract: A system for group managing plural elevator cars according to a group management algorithm including plural parameters includes a seeking apparatus for seeking the optimum parameter set, the optimum set being taken from combinations of parameter values given to the group management algorithm. Some new sets are produced by crossover or mutation in the operation of the system. Excellent sets are accumulated in a memory using additional registrations in which excellent sets are additionally stored in the memory and deletions in which impaired sets are deleted from the memory. The optimum set is selected from the accumulated sets, so that the system can efficiently seek the optimum set.

Abstract: An elevator control apparatus determines an estimated car delay when the elevator car stops at or passes an elevator hall and controls an operation of the car using the obtained estimated car delay. The elevator control apparatus includes an input data conversion unit for converting traffic data, including position of the car, direction of movement, and car calls and hall calls, such that it can be used as input data of a neural net. An estimated car delay operation unit includes an input layer for taking in the input data, an output layer for outputting the estimated car delay, and an intermediate layer provided between said input and output layers in which a weighting factor is set. An output data conversion unit converts the estimated car delay output from the output layer such that it can be used for a predetermined control operation. The estimated car delay operation unit constituting a neural net.

Abstract: An elevator control apparatus determines the time required for a call to reach a hall and controls an operation of the car using the obtained estimated travel time. The elevator control apparatus includes an input data conversion unit for converting traffic data, including car position, car direction data, and data regarding car calls and hall calls into data that can be used as input data to a neural network. An estimated travel time operation unit including an input layer is provided for taking in the input data. An output layer is provided for outputting the estimated travel time. An intermediate layer is provided between the input and output layers in which a weighting factor is set. The estimated travel time operation unit comprises a neural network and an output data conversion unit for converting the estimated travel time output from the output layer into data that can be used for a predetermined control operation.

Abstract: An elevator control apparatus determines an estimation of a car's crowdedness based on the a car's crowdedness when the car stops or passes an elevator hall, and controls an operation of the car using the obtained estimated car crowdedness.

Abstract: A group control method apparatus for elevators including a plurality of cars for serving floors divided into a plurality of sectors. The apparatus has a determination coincidental ride prevention section for assigning a hall call to one of the plurality of cars in such a manner that passengers from different ones of the sectors will not ride on the same car.

Abstract: An elevator control apparatus capable of predicting reversion floors of elevator cages accurately. The control apparatus comprises a neural network, in which traffic state data are fetched into the neural network, so that predicted values of floors where the moving direction of each cage is reversed are calculated as predicted reversion floors. In the elevator control apparatus, reversion floors near true reversion floors can be predicted flexibly correspondingly to traffic state and traffic volume.

Abstract: A group management method and apparatus for elevators is disclosed. The apparatus includes a car-position predicting device for predicting a car position and a car direction which will have been taken by each car when a predetermined time has elapsed, a predicted-empty-car detecting device for predicting from the predicted car position and direction an empty car which will be available when the predetermined time has elapsed, and an assignment restricting device for restricting the assignment of the predicted empty car to a floor call. In the group management method, a waiting time derived from a registered floor call which is assigned to each car is evaluated, and a car to be assigned to the floor call is selected on the basis of the result of the evaluation.

Abstract: A method and apparatus for group-supervising an elevator system according to this invention consists in predicting the position of operating cages after the lapse of a predetermined time, detecting an unoccupied cage and tentatively setting the standby position thereof, so as to predict the position of unoccupied cages after the lapse of the predetermined time under the condition that the detected unoccupied cage is run to the set position and is caused to stand by there, predicting, from the positions of the cages, the number of cages which will lie in certain floors or certain floor zones after the lapse of the predetermined time and estimating the numbers of cages in association with the floors, whereby the floor in which the unoccupied cage is to stand by is selected.

Abstract: A display apparatus for an elevator in which a message to be reported to the users of the elevator, such as the running status of the elevator, is displayed by a display unit disposed in a cage or a hall, a control is performed by a display control device so that the message to be reported may be displayed in a designated display aspect on the display unit, and the designation of the display aspect and the simulative display of a message in an aspect corresponding to the designated display aspect are carried out with a display aspect correction device, whereby the display as intended can be presented.

Abstract: A group-supervisory apparatus for an elevator system includes an apparatus which registers hall calls when hall buttons are depressed, selects a cage to serve from among a plurality of cages and assigns it to the hall call, performs operation controls such as determining a traveling direction of the cage, starting and stopping the cage, and opening and closing a door of the cage, thereby causing the cage to respond to a cage call and the allotted hall call, and causes the cage to stand by at a floor at which it has responded to the last call or to travel to and stand by at a predetermined floor. The apparatus predictively calculates cage positions and cage directions after the respective cages have successively responded to the cage calls and the allotted hall calls since the current time and a predetermined time has lapsed.

Abstract: A group supervision apparatus for an elevator system having hall call registration devices for registering each hall when a hall button is depressed, assignment apparatus for selecting a cage to-serve from among a plurality of cages and assigning the selected cage to the hall call, cage control apparatus for performing operation controls such as determining travelling directions of the cages, starting and stopping the cages, and opening and closing doors of the cages, and for causing the cages to respond to cage calls and the hall calls allotted to the assigned cages, and standby devices for causing, when the cages have responded to all the calls, the cages to stand by at floors where they have responded, or to run to predetermined floors and stand by; the apparatus being so constructed that cage positions and cage directions of the respective cages to arise after the cage calls and the allotted hall calls have been successively responded to since the present point of time, during a predetermined time, are pr
