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. One method of scheduling dispatch includes obtaining a measure of estimated passenger demand for travel in one direction that is incapable of being met by cars currently in service. A passenger loading threshold limit for travel in the one direction is selected which may range from zero to maximum capacity of the elevator car to be dispatched. When the measure of estimated passenger demand for travel in the one direction that is incapable of being met by cars currently in service equals the passenger loading threshold limit a car dispatch signal is issued for dispatch of a car from the terminal floor. Where a plurality of independently-operated cars are included in a hoistway, operation in either a coupled or decoupled manner is provided.

Abstract: An elevator system is shown that includes an elevator shaft (12) in building (10) and a plurality of elevator cars (C.sub.1, C.sub.2 and C.sub.3) that are movable up and down within the shaft along vertical axis (20). The elevator cars are independently movable by drive motors (D.sub.1, D.sub.2 and D.sub.3) attached to the cars through hoisting cables (24, 28 and 34). The motors are controlled by motor controllers (MC.sub.1, MC.sub.2 and MC.sub.3) which, in turn are controlled by a computer (62) having as inputs service and destination requests, load weight and car location. Different operating modes are shown (FIGS. 5-8) including one in which serviced floors (F.sub.1 through F.sub.16) are serviced by no more than one elevator car at a time, and the cars travel sequentially from one end floor to the other end floor (FIGS. 5 and 6). Simultaneous servicing of a plurality of different floors is shown (FIGS. 7 and 8) and travel of empty elevator cars to a designated floor without responding to floor calls also is shown (FIGS. 6 and 8). Counterweights (CW.sub.1, CW.sub.2 and CW.sub.3) are attached by cables to the respective elevator cars (C.sub.1, C.sub.2 and C.sub.3), which counterweights travel along a vertical axis (38) laterally displaced from the elevator car axis (20). Shock absorbers (54) are provided for absorbing impact of accidental collision between adjacent counterweights (FIG. 3 ) which shock absorbers include coil springs (58) and dashpots (60).
