Title:
METHOD AND ELEVATOR SCHEDULER FOR SCHEDULING PLURALITY OF CARS OF ELEVATOR SYSTEM IN BUILDING
Document Type and Number:
WIPO Patent Application WO2004113216
Kind Code:
A3
Abstract:
A method schedules cars of an elevator system in a building. The method begins execution whenever a newly arrived passenger presses an up or down button to generate a call for service. For each car, determine a first waiting time for all existing passengers if the car is assigned to service the call, based on future states of the elevator system. For each car, determine a second waiting time of future passengers if the car is assigned to service the call, based on a landing pattern of the cars. For each car, combine the first and second waiting times to produce an adjusted waiting time, the method ends by assigning a particular car having a lowest adjusted waiting time to service the call and minimize an average waiting time of all passengers.
