Abstract
A method for assigning an elevator car to respond to a call signal includes a controller that determines which elevator car will respond to the call signal based on certain time metrics. The controller receives a hall call signal, and based on certain time metrics that can include, e.g., an estimated wait time (EWT), and/or estimated travel time (ETT), assigns the call signal to an elevator car. In this example, EWT represents the time a passenger is waiting for an elevator car to arrive, and ETT represents the it takes for a passenger to reach their destination once having boarded an elevator car. In some versions, an estimated time to destination (ETD) is used in determining which elevator car to assign, where ETD represents the sum of EWT and ETT. In some versions, a handling capacity coefficient (HCx), which reflects current traffic conditions, is used in determining which elevator car to assign.
