Elevator group supervisory control system
First Claim
1. An elevator group supervisory control system for providing service of a plurality of elevators to a plurality of floors by selecting the most suitable car among them, when a hall call is made, to assign to the hall call, comprising:
- temporary assigning means for performing a first step assignment operation producing first step data indicating an optimal elevator based on group data indicating various states of said elevators when the hall call is made;
a neural net for receiving input patterns in which the first step data of said first step assignment of said temporary assigning means is converted into numerical values together with other group data and outputting an assignment fitness for each of said elevators as an output pattern which indicates a selected one of said elevators to be assigned to said hall call; and
assigning means for assigning the selected one of the elevators at a second step based on the output pattern of said neural net.

Abstract
An elevator group supervisory control system for selecting the most suitable car among a plurality of elevators, when a hall call is made, to assign to the hall call, comprising: temporary assigning means for temporarily assigning the car by a conventional method such as a fuzzy group supervisory control based on group data representing states of the elevator system at the moment when a new hall call is made; and a neural net for receiving numerical values converted from group data including the result of judgment of the temporary assigning means and outputting an assignment fitness of each elevator. It decides the most suitable elevator from the output pattern of the neural net to assign to the hall call.
