  • Patent number: 12198093
    Abstract: A luggage delivery management system manages a service of delivering luggage deposited by a user to a destination specified by the user. The luggage delivery management system acquires payment amount information indicating an amount equivalent to a payment amount paid by the user for the service. When multiple pieces of luggage of a plurality of the users are delivered by one vehicle, the luggage delivery management system determines whether to set priority of the multiple pieces of luggage. The luggage delivery management system sets the priority of the luggage of the user who pays more to be higher based on the payment amount information when the priority is set. Then, the luggage delivery management system sets a luggage delivery route of the vehicle such that the multiple pieces of luggage are delivered to the destinations in accordance with the priority.
