Elevator group control system

Abstract

An elevator group control system is obtained which is improved in the operating efficiency of entire cars by determining an assigned car with the use of an evaluation value calculated from an increment of the number of floors to be stopped by each car when a hall destination call newly generated by a hall control panel is temporarily assigned to each car. The system includes a hall input unit which is installed in a hall and by which the registration of a destination floor call is able to be made, and an assignment evaluation value calculation unit which includes a plurality of evaluation value calculation units for calculating the respective evaluation values of a plurality of cars in an individual manner, determines a final evaluation value from the respective evaluation values, and selects an optimal assigned car. The assignment evaluation value calculation unit includes a stop number increment evaluation value calculation unit, and the stop number increment evaluation value calculation unit sets an increment variable from an increment of the number of floors to be stopped at the time when a new hall call newly generated and a new hall destination call representing a destination floor of the new hall call are temporarily assigned to each of the plurality of cars, and calculates a stop number increment evaluation value based on the increment variable thus set.
