Method and system for elevating elevator cars including allocating elevator cars to serve load calls

An elevator system, comprising

• an elevator group including an elevator, the elevator including an elevator shaft and an elevator car configured to move within the elevator shaft, the elevator car having a floor area;
• a communications interface configured to communicate with a terminal device;
• and
• an elevator group control device configured to
• receive a load call via the communications interface, the load call including information indicating
• a departure floor,
• a destination floor,
• load specification data associated with a load, and
• a time period wherein the load is to be transported from the departure floor to the destination floor,
• allocate the elevator car to serve the load call, to prioritize the elevator car to serving the load call over serving another load call within the time period, the allocating including
• reserving a particular portion of the floor area of the elevator car for the load during a portion of the time period, based on the load specification data and the particular portion being available to accommodate the load during the portion of the time period, and
• causing the elevator car to, within the portion of the time period and subsequently to reserving the particular portion of the floor area of the elevator car for the load during the portion of the time period, first move to the departure floor to accept the load within the particular portion of the floor area of the elevator car and subsequently move from the departure floor to the destination floor to enable offloading of the load from the particular portion of the floor area of the elevator car at the departure floor, and
• transmit a notice to the terminal device via the communications interface based on the allocating, the notice indicating
• the elevator car as a particular elevator car that is to serve the load call during the time period,
• arrival of the elevator car at the departure floor to serve the load call, or
• a combination thereof, wherein
• the load specification data indicates that the load is configured to be divided into a plurality of partial loads,
• the allocating includes dividing the load according to the load specification data into the plurality of partial loads, based on a determination that, within the time period, there is no space for the load available in a single elevator car, and
• the elevator group control device is configured to transmit a separate notice to the terminal device, the separate notice indicating the dividing.
