Elevator group supervisory control system

An elevator group control system to control multiple elevators each of which serves a plurality of floors, comprising:

• first reference route generating means which generates a reference route which indicates reference positions of a first elevator during a certain period starting from the present time;
• second reference route generating means which generates a reference route which indicates reference positions of a second elevator during a certain period starting from the present time;
• and
• assignment means which selects a car for assignment to a generated hall call so as to either make an actual trajectory of the first elevator, which indicates actual positions of the first elevator in real time, closer to the first reference route of the first elevator or make an actual trajectory of the second elevator, which indicates actual positions of the second elevator in real time, closer to the second reference route of the second elevator.

An elevator group control system to control multiple elevators each of which serves a plurality of floors, comprising:

• reference route generating means which for each elevator, generates a reference route which indicates reference positions of the elevator during a certain period starting from the present time;
• predicted route generating means which, for each elevator, generates a predicted route indicating predicted positions of the elevator during a certain period starting from the present time;
• evaluation means which, for each elevator, calculates an evaluation value of the predicted route with respect to the reference route;
• and
• assignment means which selects an elevator for assignment to a generated hall call based on the evaluation values calculated by the evaluation means.

• reference route generating means which, for each elevator, generates a reference route which indicates reference positions of the elevator during a certain period starting from the present time;
• predicted route generating means which, for each elevator, generates a predicted route indicating predicted positions which the elevator would go through during a certain period if the elevator is assigned to a generated hall call;
• evaluation means which, for each elevator, calculates an evaluation value of the predicted route with respect to the reference route;
• and
• assignment means which selects an elevator for assignment to the generated hall call based on the evaluation value calculated by the evaluation means.

An elevator group control system to control multiple elevators each of which serves a plurality of floors, comprising:

• reference route generating means which for each elevator, generates a reference route which indicates reference positions of the elevator during a certain period starting from the present time;
• assignment means which selects an elevator for assignment to a generated hall call based on the reference routes generated for the respective elevators;
• means which displays the reference route of each elevator and the actual trajectory indicating actual positions of each elevator in real time;
• and
• means which changes the reference route of each elevator.

An elevator group control system comprising:

• a group control device to control multiple elevators each of which serves a plurality of floors;
• and
• individual-elevator control devices which control the respective elevators based on a signal from the group control device;
• wherein the group control device comprises:
• reference route generating means which, for each elevator, generates a reference route which indicates reference positions of the elevator during a certain period starting from the present time;
• and
• assignment means which selects a car for assignment to a generated hall call so as to make an actual trajectory of each elevator, which indicates actual positions of the elevator in real time, closer to the reference route of the elevator;
• and
• the individual-elevator control devices control the elevators based on the elevator assignments of the assignment means.
