A system includes a device and one or more information processing apparatuses. The device includes a device-information generator configured to generate device information on the device; and an analyzer determining unit configured to determine any one of the device and the one or more information processing apparatuses as an analyzer for the device information. The one determined as the analyzer includes an analysis unit configured to perform an analysis based on the device information; and a service determining unit configured to determine a service to the device based on a result of the analysis.

System, service determining method, and computer program product

An information processing apparatus includes a first storage device configured to store device data output regularly or non-regularly from a device connected to the information processing apparatus; a second storage device configured to store maintenance report data related to maintenance work performed on the device; and a processor. The processor is configured to evaluate whether the device on which the maintenance work was performed operates normally, based on the device data stored in the first storage device, and the maintenance report data stored in the second storage device, to generate an evaluation result; and send a notice of the evaluation result, to a terminal device connected to the information processing apparatus.

Information processing system, information processing apparatus, and medium

An information processing system includes one or more information processing apparatuses for determining lifetimes of components, to be replaced by preventive maintenance, of respective electric devices. The information processing system includes a leading variable specifying unit configured to specify, based on variables that represent use states of the electric devices and failure data of the electric devices which have been obtained from the electric devices, a plurality of leading variables relevant to the lifetimes of the components; a lifetime matrix creating unit configured to classify a plurality of values of each of the leading variables into sections to create a lifetime matrix in which the lifetimes of the components are set with respect to combinations of the sections each of which relates to a different leading variable; and a lifetime outputting unit configured to determine the lifetimes of the components with respect to the respective electric devices.

System, method, and non-transitory recording medium for determining lifetimes of components of multifunction peripherals

An information processing system includes a storage unit that stores and associates a cause of a failure that has occurred in an electronic device, state information of the electronic device at the time the failure has occurred in the electronic device due to the cause of the failure, and a measure to be implemented in response to the cause of the failure. The information processing system further includes at least one processor that performs an acquisition process for acquiring the state information of the electronic device, and a failure diagnosis process for determining the cause of the failure that has occurred in the electronic device and the measure to be implemented in response to the cause of the failure based on the acquired state information of the electronic device.

Information processing system and failure diagnosis method

An information processing system includes a determining unit configured to determine, based on use amounts, for predetermined respective periods, of a device, whether a period during which a use amount of the device increases is present; a deciding unit configured to determine whether maintenance work is to be performed on the device in a case where the determining unit determines that the period during which the use amount of the device increases is present and to decide details of the maintenance work; and an outputting unit configured to output the details of the maintenance work. The deciding unit decides the details of the maintenance work including at least one of a check item name that is in accordance with the device and a replacement component name that is in accordance with a predicted use amount of the device in the period.

Information processing system, information processing method, and computer program product

A log management system stores association data indicating association between program identification information for identifying a program that requests execution of one or more functions at an information processing apparatus, and function identification information for identifying each one of the one or more functions to be executed by the program, receives program identification information for identifying a program that requests the information processing apparatus to execute one or more functions from the information processing terminal on which the program is installed through the network, and obtains function identification information that is associated with the program identification information received from the information processing terminal using the association data.

Apparatus, system, and method of log management, and recording medium storing log management program

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).

Demand forecasting method, system and computer readable storage medium

A data collecting unit receives a plurality of types of status data from an image forming apparatus and stores the status data in a status database. A data generating unit generates a plurality of types of target data for determining a maintenance sign, based on the status data. A first determining unit determines whether each of the status data exceeds a predetermined reference value. A second determining unit performs weighted majority decision based on a determination result from the first determining unit and a weight value set for each of the status data, and determines whether there is a maintenance sign taking all the status data into consideration.

Management apparatus, management system, operation status determination method, and image forming apparatus

An apparatus, method, system, computer program, and product, each capable of detecting a state of an apparatus. The apparatus includes a plurality of devices. When at least one of the plurality of devices is determined to be in a first state, a second state of at least one of the plurality of devices is determined. When a state of the apparatus is determined to be in the first state, the second state of another apparatus is determined.

Apparatus, method, and system for detecting a state of an apparatus

An image forming apparatus is provided. The image forming apparatus includes an acquiring unit that acquires a plurality of types of operation control information of the image forming apparatus that indicate deterioration of a toner in the image forming apparatus or deterioration of a component of the image forming apparatus. An index value calculating unit calculates an index value indicating a state of the image forming apparatus based on the acquired operation control information. An abnormality judging unit judges whether the image forming apparatus abnormality has occurred and predicts an occurrence of a failure that requires maintenance of the image forming apparatus due to deterioration of the toner in the image forming apparatus or deterioration of the component of the image forming apparatus based on the index value.
