  • Publication number: 20250225456
    Abstract: An online concierge shopping system fulfills orders using workers who pick items at a warehouse to complete an order and workers to deliver the orders to a customer's location. To optimize the staffing of workers for each task, the system uses a trained model to predict the number of workers needed to achieve an optimal outcome based on an input set of contextual information. The system also schedules specific workers to various shifts using the predicted number of workers needed and then searching a feasibility space for an optimal solution. The trained model may be updated based on performance observations.

  • Publication number: 20220270027
    Abstract: An online system receives, scans from a plurality of picker client devices. Each scan comprises an item identifier and a location in a store where the item was scanned. The online system creates a map of the store based on location data received from a picker client device as a picker moves around the store. Using the map and the scans, the online system builds a planogram of the store. The planogram comprises a mapping of a plurality of locations in the store to one or more items at each of the plurality of locations. The online system receives an order of items to be fulfilled at the store from a customer client device and determines location information describing locations of the items in the store based on the planogram. The online system transmits, to a picker mobile device, the location information for display.

  • Patent number: 10802668
    Abstract: In one embodiment, a virtual room-based user interface is provided. The interface displays a view of a virtual room that corresponds to a physical room and that includes a representation of a first device present in the physical room and at least one of a portion of structure of the physical room or a portion of furnishings present in the physical room. User input is received via the interface that indicates a change of state in the physical room. In response to the user input, a change is caused to a state provided by the first device, and the interface dynamically updates appearance of the virtual room to change appearance of the representation of the first device and at least one of the portion of the structure of the physical room or the portion of the furnishings present in the physical room to reflect the change to the state.

  • Patent number: 10613704
    Abstract: In one embodiment, a virtual room-based user interface suited for use on a “small screen” is provided that organizes representations of devices in a virtual room into a sequence, allows a user to cycle through the representations of devices in the sequence so only a single one is selected at any given time, and individually control the device corresponding to a selected representation using a designated control region separate from the representation of the selected device.
