Abstract:
A group-supervising control system for an elevator comprising:hall call registration means for registering a hall call based on operation of a hall button provided at a hall on each floor;assignment estimation value calculation means for calculating assignment estimation values for selecting and assigning a cage-to-serve among a plurality of cages;cage assignment means for assigning a most appropriate cage among said plurality of cages based on said assignment estimation values to a hall call registered in said hall call registration means to transmit to a corresponding cage control system an assignment output for making said cage serve the hall where said hall call is generated;control means comprising:cage position prediction means for predicting, based on present cage positions, cage positions after a predetermined time period elapses;service available time period distribution calculation means for, based on the cage positions predicted by said cage position prediction means, calculating distributions of time periods until service is available, that is, expected arrival times at the respective floors of a cage capable of responding to a hall call earliest; andassignment correction value calculation means for calculating assignment correction values for correcting said assignment estimation values, based on said distributions of the time periods until the service is available,said cage assignment means correcting said assignment estimation values based on said assignment correction values to select the most appropriate cage and to transmit an assignment output.
