Abstract: A method of allocating elevator cars to operating groups in which the cars execute travel tasks for specific zones. For example, each elevator car can be assigned to an operating group (EXP) for long-distance trips, an operating group (LOC) for local trips, or a group (FREE) for free elevator cars. If a travel task passes through a blind zone, the most favorable elevator car is selected from the EXP operating group or the FREE group. If the selected elevator car belongs to the FREE group, the car is allocated to the EXP operating group while taking account of certain parameters. If a travel task does not pass through a blind zone, the most favorable elevator car is selected from the LOC operating group or from the FREE group. If the selected elevator car belongs to the FREE group, the car is allocated to the LOC operating group, while taking account of certain parameters. On expiry of a specified time with no travel task, an elevator car of the EXP and LOC operating groups is allocated to the FREE group.

Abstract: A system and method for optimally allocating elevator cars of an elevator group to serve downpeak traffic. The system monitors a "snap shot" of pending down hall calls and forms groups based upon an initialized floor separation value or response range. If the number of groups formed is greater than the number of available elevator cars in the elevator group, the system increments the floor separation value by "+1" and regroups the "snap-shot" of pending down hall calls. This procedure may be repeated until the number of formed groups is equal to or less than the number of allocable elevator cars. The system may then allocate each formed group to a respective available elevator car to serve the downpeak traffic.

Abstract: In a vertically movable elevator group management control apparatus for control of a plurality of transversely shiftable cars among plural shafts, control is done by storing route data with respect to each said car, generating target floor data including a target floor, based on car call data obtained in correspondence with each said car and station call data as obtained correspondingly to each floor, estimating the time taken for said car to reach said target floor, based on at least said route data, said target floor data and said car call data, and assigning a certain car to a certain floor call, based on the estimated arrival time.

Abstract: An elevator system for a multistory structure having a plurality of elevator shafts is shown which includes at least one independently movable elevator car in each elevator shaft. A digital computer with memory is used to control elevator cars including the dispatch of cars from terminal floors. A daily control parameter table in memory identifies a plurality of different methods of scheduling dispatch of elevator cars from terminal floors, groups of floors to be serviced by each elevator car, and cars in a shaft to be coupled for tandem operation. The memory is periodically read for selecting for each elevator car one of said methods of scheduling dispatch and for identifying the group of floors to be serviced by the cars. The selected method of scheduling the dispatch of cars is implemented and cars are limited to servicing the selected group of floors.

Abstract: An elevator system for up-peak servicing of a building having a dual lobby. The system includes a controller having an electronic processor coupled to a memory; a plurality of elevator cars controllably connected to the controller, a dual lobby routine stored within the memory, the dual lobby routine includes instructions for dispatching at least one of the elevator cars to a lower lobby during up-peak, indicating a sector assigned to the car, nudging (if needed) the car if a lower lobby time-out is exceeded, dispatching the car to the upper lobby if a load weight threshold is not exceeded, and then indicating the sector assigned to the car while the car is located at the upper lobby.

Abstract: Instantaneous car assignment is combined with sectoring for providing an elevator dispatching scheme in which, in response to a hall call registered at the lobby, a car not assigned to a sector and having the lowest remaining response time of all such cars is assigned to the next available sector and the sector assignment is displayed to passengers immediately on a screen in the lobby.

Abstract: A computer controlled elevator system (FIG. 1) including signal processing means for dynamically computing the population spread of the building, i.e., the number of elevator users in a building on a floor-by-floor basis, including the lobby, in accordance with an algorithm (FIG. 2). During the up-peak period each floor's population is computed by monitoring the boarding and de-boarding counts and using those counts to update that floor's population figure throughout that period on an additive basis. After the period has been completed, the floor-by-floor information, which had been maintained in a table, is used to determine the "final" historic based floor population spread using also historic data based at least on the past several active days' of population spread using "exponential smoothing." As a verifying cross-check the lobby's figure, which typically should equal the total building population, is compared to the total of all of the upper floors' populations.

Abstract: During downpeak time period of an elevator system, cars are assigned to sectors of an approximately equal number of floors with remaining floors being assigned to sectors near the lobby, one car per sector. The invention provides a dispatching strategy for serving elevator traffic in both up and down directions, giving priority service to the down traveling traffic while providing limited service to the up traveling traffic. All floors requiring down service are given equal access to the system regardless of the position of the floor in the building.

Abstract: An elevator system has a low rise group of floors and a high rise group of floors and a swing car having doors and car call buttons enabling it to operate in either the low rise or high rise, the swing car being assignable to one or the other rise depending upon the burden, but also being able to accept calls in the other rise in response to a variety of characteristics of traffic within the elevator system. In one embodiment, the swing car is always assigned at the lobby to the low rise but proceeds into the high rise in response to hall calls therein; the swing car can accept down calls in the low rise if there is a high burden in the low rise or a down call has been waiting for a long time, or if the car has a very light load. Dedicated cars may be shut down and only the swing cars used at nights and on weekends. At nights and on weekends, the high rise and low rise can be effectively merged into a single system served by swing cars, thereby to save energy in light traffic.

Abstract: Deeming a full elevator car available for servicing a hall call is accomplished by testing if all of the car calls for the car are between the position of the elevator car and the hall call. If not, the full car may still be deemed available if there is a special stop car call between the position of the car and the position of the hall call or if there is at least one car call between the position of the car and the position of the hall call and there are no other hall calls between the position of the car and the position of the hall call.

Abstract: In an elevator system having a low rise group of floors and a high rise group of floors and a swing car having doors and car call buttons that enable it to operate in both the low rise group of floors and the high rise group of floors, interise hall calls made within one of said group of floors for service within another of said group of floors are assigned to the swing car for response. In one embodiment, the call is assigned to the first car approaching the call in the right direction; in another embodiment, the call is assigned in accordance with ordinary hall call assignment logic.

Abstract: An elevator group control device includes a call allotment judgment means 5A which allots the cages to a newly registered destination floor selected by a passenger pushing a destination button upon a destination button board 1. The call allotment judgment means 5A first determines whether or not there exist a cage with a service schedule including the destination floor. If the judgment is affirmative, the destination floor is allotted to the cage. If not, it is judged whether or not there exist cages with a service schedule extending to a floor within a predetermined range above or below said destination floor. If there are a plurality of cages, the cage with a narrower service schedule is selected. If there exist only one cage, such cage is selected. Then, the service schedule of the selected cage is extended to include the destination floor. If there is no cage with the above requirement, a cage hitherto without a service schedule is selected and a new service schedule is created therefor.
