Abstract: A near-optimal scheduling method for a group of elevators uses advance traffic information. More particularly, advance traffic information is used to define a snapshot problem (24) in which the objective is to improve performance for customers. To solve the snapshot problem (24), the objective function is transformed into a form to facilitate the decomposition of the problem into individual car subproblems (26). The subproblems (26) are independently solved using a two-level formulation, with passenger to car assignment (28) at the higher level, and the dispatching of individual cars (30) at the lower level. Near-optimal passenger selection and individual car routing (38) are obtained. The individual cars are then coordinated through an iterative process (40, 42) to arrive at a group control solution that achieves a near-optimal result for passengers.

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.

Abstract: During elevator modernization, a cross-dispatching system receives hall calls and assigns each hall call to either a group of existing elevator car controllers or a group of new elevator car controllers. The cross-dispatching system creates an inter group relative system response (iRSR) value for the hall call for both the existing group of elevators and the new group of elevators, based upon information from each group such as car location, in-service status, load, and direction. If the group assigned the hall call does not answer the call within a redispatch time period, the cross-dispatching system again calculates the iRSR for each group and reassigns the hall call.
