Abstract
An improved elevator system and control method thereof is provided for effectively scheduling elevator cars and reducing hoistway spaces. The elevator system of the present invention includes at least one hoistway and at least two elevator cars operating independently in the hoistway. The elevator system schedules multiple elevator cars for multiple calls on the basis of information obtained by analyzing various signals provided from the button panels installed at elevator cars and elevator entrances of a building, thereby improving operation efficiency of the elevator system.
