Allocation of calls in a lift installation

A non-transitory computer readable memory programmed storing instructions that, when executed by a processor, configure the processor to perform operations comprising:

• determining, for a lift journey by the processor executing the instructions, a start zone in a building, the start zone comprising input building floors identified in destination calls inputted by two or more passengers;
• determining, for the lift journey by the processor executing the instructions, a destination zone in the building, the destination zone comprising destination building floors identified in the destination calls;
• selecting, by the processor executing the instructions, a stopping floor from the start zone of floors or from the destination zone of floors, the selecting of the stopping floor being based on a selection criterion;
• and
• transporting, responsive to said determining and selecting by the processor executing the instructions, the two or more passengers in a car of a lift installation between the start zone and the destination zone during the lift journey, the transporting comprising omitting a stop at at least one of the input building floors or at least one of the destination building floors.

A computer implemented lift installation operating method, comprising:

• receiving, using a destination call input terminal, a destination call for a passenger, the destination call being associated with an indicated departure floor in a building and with an indicated destination floor in the building;
• determining, using a computer having at least one central processing unit including at least one processor configured to execute instructions stored on the at least one non-transitory computer-readable medium, a start zone of floors in the building and a destination zone of floors in the building;
• and
• selecting a stopping floor based on selection criteria and stopping the lift car at fewer than the identified input floors and the identified destination floors.
