Abstract:
An optimal control method and system of a group of elevator cars is provided. A matrix of origin halls and destination halls is used. In this matrix, each element is referred to as a mission unit. Also, mission groups are defined. Each of the mission groups has one or more mission units and is serviceable by one of the elevator cars. Further, a mission group set is defined as a set of the mission groups provided for the group of elevator cars. Then, the mission groups are dynamically allocated to the group of elevator cars, which produces effective traffic control of the elevator cars.
Abstract:
An apparatus for performing a group control on elevators is disclosed, by which a total operation of the elevators for respective floors of building is controlled. This apparatus includes condition-instruction table which contains a plurality of predetermined control rules being defined by given conditions and given instructions. The apparatus also includes an elevator controller for detecting, in accordance with a specific rule selected from the control rules, a degree of establishment of the given conditions to provide a detected condition, and for generating, in accordance with the detected condition, an elevator control instruction used for performing the group control.
Abstract:
An elevator passenger traffic measuring system distributes passengers whose destination floors cannot be determined to each of origin-destination floor pairs in accordance with an elevator car position, an incoming passenger number and an outgoing passenger number at each floor, and registered car calls, using probability weights for the origin-destination floor pairs which are determined by previous traffic measurements. The system then estimates the number of passengers for each of the origin-destination floor pairs in accordance with the distributed passengers, and the passengers who moved the corresponding one of the origin-destination floor pairs.
Abstract:
An elevator control system includes one elevator control for each elevator car, one group supervisory device for each floor connected in two ways to the elevator controls, a group supervisory accessory connected to group supervisory devices, and a statistical device connected to the group supervisory devices and also to the group supervisory accessory. The group supervisory accessory calculates a car suspending time interval at each of the forward floors in a direction of travel of the elevator car in accordance with a percentage getting-off or -on from the statistical device by considering car and floor calls and the number of passengers within the elevator car increased due to non-responding floor calls and also a presumed arrival time interval at each floor. The group supervisory devices receive those presumed arrival time intervals to assign the optimum elevator car to the desired floor call through an associated one of the elevator controls.
Abstract:
With this group control the allocation of elevator cabins or cars to existing storey or floor calls should be timewise optimized and newly arriving storey calls should be immediately allocated. A computer device provided for each elevator computates at each landing or storey, irrespective of whether or not there is present a storey or landing call, from the distance between the storey and the cabin position indicated by a selector, the intermediate cabin stops to be expected within this distance and the momentary cabin load a sum proportional to the time losses of waiting passengers. In this way the cabin load prevailing at the computation time point is corrected such that the expected number of passengers entering and exiting the cabin, derived from the previously ascertained number of entering and exiting passengers is taken into account for the future intermediate cabin stops. Such loss time sum, also referred to as the servicing cost, is stored in a cost storage or memory provided for each elevator. During a cost comparison cycle the servicing costs of all elevators are compared with one another by means of a comparator, and in an allocation storage of the elevator with the lowest servicing cost there can be stored an allocation instruction which designates that storey or floor to which there can be optimumly allocated the relevant elevator cabin.
Abstract:
An elevator control system for controlling a plurality of elevator cars arranged for parallel operation for servicing a plurality of service floor landings of a building, in which means are provided so that, in response to origination of a new hall call in addition to hall calls originated and allotted already, a suitable car for servicing this new hall call can be selected and the new hall call can be allotted to the selected car to be serviced by the selected car. In the system, the change in the service condition of all the cars for the already allotted hall calls due to allotment of this new hall call thereto is taken into account in selecting the suitable car. For example, means are provided for computing for each car the forecast waiting time at each of the already allotted floors to be serviced thereby to detect the change in the forecast waiting time when this new hall call originating floor is serviced. The new hall call is allotted to the car which provides a forecast waiting time less than a predetermined limit, and this car services this specific floor.
Abstract:
PROBLEM TO BE SOLVED: To provide a group supervisory control method and a system for elevators, capable of efficiently controlling the operation of the elevators in various traffic statuses and various specification conditions required for the group-control system. SOLUTION: In the group supervisory control method for elevators by operating a plurality of elevators relative to a plurality of floors, computing an evaluation index to a newly generated landing call and selecting the optimum car and assigning based on the evaluation index, as the evaluation index, an expectation value of the waiting time of all the passengers (a total or an average expectation value of the waiting time) for every direction in each floor, which is already generated or estimated to be generated in a predetermined time, is used.

Abstract:
A method for determining an allocation decision for at least one elevator includes using an existing calls in an elevator system as a first input in a machine learning module, processing the first input with the machine learning module to provide a first output comprising a first allocation decision, using the first output as a second input in an iterative module, processing the second input with the iterative module to provide a second ouput comprising a second allocation decision, and providing the second allocation decision to an elevator control module and to an allocation decision storage for further machine learning module training.
