"Artificial Intelligence" based learning system predicting "Peak-Period" times for elevator dispatching

In an elevator dispatching system controlling the assignment of elevator cars from a lobby level to various floors in a building having a predetermined population, a method of determining the conclusion of an UP-PEAK period of operation, said method comprising the steps of:

• obtaining historical information of the number of passengers boarding the elevators at the lobby during a plurality of predetermined time intervals, said time intervals being within a predetermined time period;
• predicting a lobby boarding count for a specific predetermined time interval based on said historical information;
• comparing said predicted lobby boarding count with a predetermined percentage of the building's population;
• and
• concluding UP-PEAK operation at the beginning of said specific time interval if said predicted lobby boarding count is less than said predetermined percentage of the building's population.

In an elevator dispatching system controlling the assignment of elevator cars from various floors to a lobby level in a building having a predetermined population, a method of determining the commencement of a DOWN-PEAK period of operation, said method comprising the steps of:

• obtaining historical information of the number of passengers deboarding the elevators at the lobby during a plurality of predetermined time intervals, said time intervals being within a predetermined time period;
• predicting a lobby deboarding count for a specific predetermined time interval based on said historical information;
• comparing said predicted lobby deboarding count with a predetermined percentage of the building's population;
• and
• commencing DOWN-PEAK operation at the beginning of said specific time interval if said predicted lobby deboarding count is greater than said predetermined percentage of the building's population.

In an elevator dispatching system controlling the assignment of elevator cars from various floors to a lobby level in a building having a predetermined population, a method of determining the conclusion of a DOWN-PEAK period of operation, said method comprising the steps of:

• obtaining historical information of the number of passengers deboarding the elevators at the lobby during a plurality of predetermined time intervals, said time intervals being within a predetermined time period;
• predicting a lobby deboarding count for a specific predetermined time interval based on said historical information;
• comparing said predicted lobby deboarding count with a predetermined percentage of the building's population;
• and
• concluding DOWN-PEAK operation at the beginning of said specific time interval if said predicted lobby deboarding count is less than said predetermined percentage of the building's population.

In an elevator dispatching system controlling the assignment of elevator cars from a lobby level to various floors in a building, the system having a method of determining the commencement of an UP-PEAK period of operation based on a predicted lobby boarding count and a predetermined threshold value, a method of adjusting said threshold value comprising the steps of:

• predicting said lobby boarding count based on historical information of the number of passengers boarding the elevators at the lobby during a predetermined time interval;
• comparing said predicted lobby boarding count with said predetermined threshold value;
• commencing UP-PEAK operation if said predicted lobby boarding count is greater than said predetermined threshold value;
• and
• adjusting said threshold value based on actual passengers boarding the elevators at the lobby during at least a portion of UP-PEAK operation.

In an elevator dispatching system controlling the assignment of elevator cars from a lobby level to various floors in a building, the system having a method of determining the conclusion of an UP-PEAK period of operation based on a predicted lobby boarding count and a predetermined threshold value, a method of adjusting said threshold value comprising the steps of:

• predicting said lobby boarding count based on historical information of the number of passengers boarding the elevators at the lobby during a first predetermined time interval;
• comparing said predicted lobby boarding count with said predetermined threshold value;
• concluding UP-PEAK operation if said predicted lobby boarding count is less than said predetermined threshold value;
• and
• adjusting said threshold value based on actual passengers boarding the elevators at the lobby during a second predetermined time interval after the conclusion of UP-PEAK operation.
