Abstract
A method of allocating elevator cars to operating groups in which the cars execute travel tasks for specific zones. For example, each elevator car can be assigned to an operating group (EXP) for long-distance trips, an operating group (LOC) for local trips, or a group (FREE) for free elevator cars. If a travel task passes through a blind zone, the most favorable elevator car is selected from the EXP operating group or the FREE group. If the selected elevator car belongs to the FREE group, the car is allocated to the EXP operating group while taking account of certain parameters. If a travel task does not pass through a blind zone, the most favorable elevator car is selected from the LOC operating group or from the FREE group. If the selected elevator car belongs to the FREE group, the car is allocated to the LOC operating group, while taking account of certain parameters. On expiry of a specified time with no travel task, an elevator car of the EXP and LOC operating groups is allocated to the FREE group.
