Abstract
A method and an apparatus for determining the optimal travel sequence for an elevator installation includes smart terminals sending destination specific travel requests and other planning information to a job manager for each elevator car. The job managers perform a situation-based search process to determine the optimal travel sequence plan for the associated elevator and submit an offer to the terminal sending the travel request. The terminal compares offers and books a selected one. The job managers are responsive to relevant changes in the situation upon which the plan is based for determining a changed actual travel sequence and associated changed offer.
