ABSTRACT:
A method of optimizing the handling of coincident calls in an elevator system which employs ETA strategy in assigning hall calls to a plurality of elevator cars. The method dynamically biases the ETA value of a car having a car call for the floor of the hall call being assigned, with the bias being applied to favor assignment of the hall call to the car having the coincident car call. The amount of the bias is inversely proportional to the car travel distance between the advanced position (AVP floor) of the elevator car and the floor associated with the hall call (scan floor). The relative effect of the bias is predetermined for each floor by preselection of a constant K used in the bias calculation.
