  • Publication number: 20170344929
    Abstract: An information processing apparatus includes circuitry. The circuitry acquires, from equipment in which a fault has occurred, status information indicating a status of the equipment. The circuitry checks whether a maintenance person who is in an available state is present from among a plurality of maintenance persons. The circuitry identifies a type of the fault that has occurred in the equipment, based on the acquired status information. In a case in which no maintenance person who is in the available state is present from among the plurality of maintenance persons, the circuitry instructs the equipment to output a quick fix technique, which enables working around the fault of the identified type to enable continued use of the equipment.
