Advanced AI Supervisory Control

Mitsubishi's AI Supervisory Control is the key factor in creating an ideal elevator system with optimum user service. Two basic systems are available, and between them they offer a wid range of special functions to suit the needs of any type of building.

AI-21 System
This system is designed for small or medium size buildings with two to four cars in the elevator group.

AI-2100N System
This system is designed for larger buildings with three to eight cars in the elevator group. It suits buildings with dynamic traffic conditions throughout the day and peak carrying times.

Expert System and Fuzzy Logic
The brain of the AI Supervisory Control employs an intelligent Expert System that utilizes the practical knowledge and experience of elevator group control experts. This information is stored in the system's memory as a 'Knowledge Database.' Drawing from this database, various traffic conditions are monitored and analyzed applying IF-THEN decision rules to maximize the effectiveness of each elevator operation. Mitsubishi Electric has applied fuzzy logic in a manner that enables the elevator control system to make decisions using fragmentary and fuzzy intelligence concepts. For example, using its 'intelligence' and 'common sense,' the system can determine whether or not potential car assignments will result in longer waiting times for calls in the near future or cause elevator congestion. The assessment results are applied to determine the car assignments in order to improve overall service.

Psychological Waiting Time Evaluation
This evaluation function is Mitsubishi Electric technology that originates form the psychological thought patterns of a passenger waiting for an elevator: the irritation of a passenger waiting for elevator arrival is proportional to the square of the actual waiting time. Elevator assignments to hall calls are performed on the basis of evaluation results. In addition to forecasted waiting time, such factors as probability of being by passed for a hall call, probable time required for travelling after car assignment, current car load and many others are applied in the evaluation function owing to its coefficient diversity. Car assignments to hall calls are made as a sum of all factors. (Evaluation factors vary in accordance with the basic system chosen, type of hall display, and other design parameters.)

Strategic Overall Assignment
Combining all of the building traffic conditions, the system forecasts where future service will be needed and assigns cars accordingly. This greatly reduces the average overall waiting time and provides optimum service to passengers throughout the building. Consider a simulated traffic situation involving a four-car elevator system (figure shown below). When passenger a registers a down hall call on the 10th floor, a conventional system would assess that the No. 4 car is most appropriate and assign it to service the call. However, this would cause three cars to be concentrated in the upper zone and might reduce service to the lower zone.

The AI-2100N reviews the situation, taking into consideration that if the No. 4 or No. 2 car is assigned to service the 10th floor, that the concentration of cars in the upper zone leaves service to the lower zone inadequate. The system's evaluation function then determines the No.3 car to be the most suitable and assigns it to the 10th floor call. Thusthe overall waiting time for passengers throughtout the building is substantially reduced, even though the passenger making the down call on the 10th floor waits a little longer than if the No. 4 or No. 2 car would have been assigned. Once all car and hall calls have been serviced, the system forecasts where the next likely calls for service will arise and accordingly assigns the cars so that the waiting time for future passengers is also reduced. (Strategic Overall Spotting).

Car Travel Time Evaluation
The system assigns each car to hall calls taking into consideration the number of registered car calls (as one evaluation factor), thus minimizing car travel time required after assignment.

Learning Function
The system learns the daily patterns of a building's traffic flow: incoming/outgoing traffic, lunchtime and interfloor traffic, and others. Distinctive data are stored and then applied to analyses using a statistical method. This determines the most suitable parameters in car assignments to hall calls, thus futher enhancing total performance.

Immediate Prediction Indication
Once a passenger has registered a hall call, the ideal car to respond is selected, and the hall lantern lights and a chime sounds once to indicate which door will open. As the car approaches, the lantern begins to flash and the chime sounds twice. This system provides a highly reliable prediction of car arrival and reduces passenger irritation.
