ABSTRACT:
An elevator system contains a group of elevator cars. A group controller contains signal processing means for controlling the dispatching of the cars from a main floor or lobby in relation to differnt group parameters. During up-peak conditions, each car is dispatched from the main floor to an individual plurality of contiguous floors, defining a "sector". Sectors are contiguous. The number of sectors may be less than the number of cars. Floors that constitute a sector are assigned exclusively to a car and are displayed on an indicator at the lobby. Sectors are selected for assignment according to preset order (e.g. numerical). Cars are selected for assignment to a selected sector according to a preset order (e.g. numerical). If no car calls are made to the floors in the sector that is assigned to a car, the next sector is selected along with the next car according to that order. When an up hall call is made during the up-peak period, the car that is most able to serve the call is selected if it is assigned to a sector in the upper 2/3 of the building. Cars are evaluated for the assignment from the most favorable to the least favorable until the most favorable car serving a sector in the upper 2/3 of the building is found. Cars serving floors in the lower 1/3 of the building are never assigned to up hall calls during the up-peak period.
