<p>ELEVATOR SYSTEM A new and improved elevator system, and method of directing a plurality of elevator cars to serve floor calls in an elevator system. Service is provided for floor calls which cannot be allocated to a suitably conditioned car already busy serving calls, by specifically assigning nonbusy or available cars to serve such calls. The floor calls are each timed from registration and when their registration time reaches a first value the strategy for assigning available cars to non allocated calls is changed. The timing of a call continues following the reaching of the first value, until the call reaches a second timed value. The strategy for assigning available cars to non-allocated calls is changed again, in response to a call registered for the second predetermined period of time.</p> |
