Abstract:
An elevator group control device and an elevator group control method can eliminate congestion caused by stoppage, jam or deadlock in a vertical and horizontal movement type elevator system. The vertical and horizontal movement type elevator system controls running of a plurality of cages capable of vertically moving in a plurality of shafts and horizontally moving between the shafts. In the system, path data are stored for each of the cages, target floor data including target floors are produced on the basis of call data obtained correspondingly to the respective cages and platform call data obtained correspondingly to the respective floors, periods of time required for the cages to arrive at the target floor is predicted on the basis of the path data, target floor data, call data and cage data indicative of positions of the respective cages, and predetermined cages are allotted to predetermined platform calls on the basis of the predicted arrival time.
Abstract:
Described is a method for assigning hall calls comprising the steps of receiving a hall call signal, receiving information regarding an elevator system, assigning a destination to the hall call signal, and calculating a call cost value for each elevator car using a handling capacity coefficient. The controller designates the elevator with the lowest call cost value to respond to a call signal. The handling capacity coefficient is a value that reflects the current traffic conditions of an elevator system.
Abstract:
A method and a display for elevator allocation evaluating are provided. When an elevator allocated to a hall call is selected by employing two different view points such as a real and a future call evaluation index, an elevator allocation reason and a balance between the two view points can be easily grasped. An elevator allocated to a hall call is evaluated on orthogonal coordinates in which the real call evaluation index (ΦR (k)) and the future call evaluation index (ΦF (k)) are defined as an X and a Y coordinate axis. Evaluation indexes (21 to 24) of first to fourth elevator cars are evaluated by employing contour lines (25a to 25g) of a synthetic evaluation function (ΦV (k)), which is represented as the real and the future call evaluation index. A weight for allocating is displayed visually.

Abstract:
Energy saving methods and apparatus for elevator systems having a plurality of elevator cars operating in a plurality of elevator shafts are disclosed. The present invention provides methods and apparatus for determining which one of the plurality of elevator cars is to be assigned to a new hall call in order to reduce the net energy consumption of the elevator system over time.
Abstract:
The invention relates to a procedure for controlling an elevator group consisting of several elevators and related call devices. A control system for controlling the elevators controls each elevator in a manner determined by the calls entered and the existing control instructions. According to the invention, when the control system has to decide between two or more control alternatives, a systematic decision analysis is performed by studying the effects resulting from each alternative decision, said effects being estimated by simulating by a Monte-Carlo type method the future behaviour of the elevator system in the case of each alternative decision. To carry out the simulation, realizations are generated at random for the unknown quantities associated with the current state of the elevator system and for new external future events, and a control decision is made on the basis of the results of the decision analysis.
