Abstract:
A method for increasing the transportation capacity of elevators in a building involving dividing the elevators (2-7) into two or more groups, each comprising one or more elevators, in such manner that in certain loading situations the groups will temporarily serve different zones (11, 12) of the building (1). Upward peak traffic conditions are detected and the boundaries between zones (11, 12) are determined and maintained by the steps which include:(a) detecting by a peak traffic condition, mainly on the basis of elevator loading time and/or the number of people arriving in an elevator lobby (9) of the building (1).(b) calculating an initial optimal zone boundary value mainly on the basis of traffic statistics and existing transportation capacity.(c) effecting transition of elevator operation to sub-zoning during upward peak traffic.(d) re-calculating the optimal zone boundary value mainly on the basis of short-term traffic statistics, the number of people in the elevator lobby and the available transportation capacity.(e) sensing the need for change in the zone boundary and effecting the desired change as calculated in section (d).(f) cancelling the sub-zoning upon completion of the upward peak passenger period or when the volume of upward traffic has fallen below a predetermined limit.
Abstract:
A control apparatus for elevators in which one cycle of a fluctuating demand is divided into a plurality of sections, the demand in each section or a service condition value of the elevators for the demand is measured, the demand or the service condition value of the corresponding section is estimated from the measured value, the estimated value is compared with a measured value obtained anew, so that when both the values have not been decided to differ greatly as the result of the comparison, cages may be controlled by the use of an estimative value obtained by considering the measured value obtained anew, whereas when both the values have been decided to differ greatly as the result of the comparison, the cages may be controlled by the use of the estimated value obtained without considering the measured value obtained anew, and measurement value analyzing means is comprised for analyzing the measured values differing greatly from the estimated value, in the same section, so that when a permanent change in the demand or the service condition has been noted as the result of the analysis, the cages may be controlled by the use of the estimated value obtained by considering the measured value differing greatly from the estimated value. Thus, the estimative value is caused to quickly follow up the fluctuation of the demand or the service condition value, and the responsiveness of the cages to the new demand or service condition value can be improved.
Abstract:
A control system for operating a transportation system including a plurality of vehicles, such as elevators, is disclosed wherein a history of the past performance of the transportation system is stored. This history is analyzed by a digital computer, and the operating mode of the transportation system is changed in accordance with the analysis in order to optimize the performance of the system.

PROBLEM TO BE SOLVED: To provide a lift installation for zonal operation in a building capable of enhancing the transport capacity of the whole lift installation without lowering the transport capacity of a carry-in side lift or a carry-out side lift. SOLUTION: The lift installation 10 for zonal operation in the building 30 divided into a plurality of zones 31, 32 comprises a plurality of lifts 11, 12, 13, 14 for transporting persons/goods in cages 1, 2, 3, 4, 4'. The zone is associated with every lift, and at least one changeover story 33 for the changeover of persons/goods between the cages of the different zones is arranged between the zones. At least one lift 14 comprises at least two cages 4, 4' arranged one above the other and movable independently of one another at a pair of guide rails 5, 5'. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
In an approach for determining an optimal path for an elevator, a processor receives information, wherein the information includes social media data associated with a user and calendar entries associated with the user, indicating one or more locations within a building. A processor analyzes the received information. A processor determines a location to send an elevator within the building to minimize movement of the elevator, based on the analyzed information. A processor causes the elevator to move to the location.
Abstract:
According to an aspect, there is provided a method and an apparatus for determining an allocation decision for at least one elevator. In the solution existing calls are used in an elevator system as a first input in a machine learning module. The first input is processed with the machine learning module to provide a first output comprising a first allocation decision. The first output is then used as a second input in an iterative module. The second input is processed with the iterative module to provide a second output comprising a second allocation decision. The second allocation decision is provided to an elevator control module and to an allocation decision storage for further machine learning module training.
