  • 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.

  • Patent number: 8341008
    Abstract: Disclosed are a demand forecasting method, a demand forecasting program, and a demand forecasting system that can adequately forecast a demand for a commodity. A management computer calculates a trend function with respect to demand values. The management computer then calculates the ratio of the demand values to a trend curve, and calculates a logarithm of the ratio. Then, the management computer approximates the calculated natural logarithm curve with a periodic model, and converts the logarithmic scale of the acquired periodic model to a normal scale. Demand forecasting is performed using a demand forecasting model acquired by combining a periodic change model of the normal scale with a trend curve (trend function).
