An autonomous mobile method for an autonomous mobile device according to the present embodiment is an autonomous mobile method for an autonomous mobile device that autonomously moves in a facility provided with an elevator. When the total number of the autonomous mobile devices including other autonomous mobile devices in a car of the elevator is larger than a threshold that is a plural number, an operation mode of the car is switched from a general mode in which a human is allowed to enter the car to a dedicated mode in which the human is prohibited from entering the car.

A method, system, and computer program product for occupant-based elevator actions are provided. The method identifies a set of subjects approaching a set of elevators to generate a set of identities for the set of subjects. A set of initial priority statuses are generated for the set of subjects. Based on the set of identities and the set of initial priority statuses, an elevator dispatch solution is determined. The method updates at least a portion of the initial priority statuses to generate a set of subsequent priority statuses in response to a subset of subjects entering at least one elevator. The method determines an isolation response for a first subject of the subset of subjects and modifies the elevator dispatch solution based on the isolation response to generate an isolation dispatch solution. The at least one elevator executes the isolation dispatch solution.
