There are provided a repair determination section that determines, based on failure information on the facility for manufacturing a product, a repair time required to repair the facility, and a recovery plan creation section that creates a recovery plan in accordance with a predetermined production evaluation indicator, based on the repair time and production information on a line with the failed facility, one or more other facilities, and on one or more other lines.

An equipment failure diagnosis apparatus, an equipment failure diagnosis method, a smart factory system, and an application agent configured to generate a virtual abnormal signal based on a normal signal data stored in the database, determine whether an equipment signal is an abnormal signal based on a virtual abnormal signal data for the virtual abnormal signal, and output a determination result information. Accordingly, the present disclosure can quickly and accurately diagnose a failure of equipment in a factory, even under conditions where labeling data is not present or insufficient.

A sensor device transmits, to an external device installed external to the sensor device, sensing data generated from monitoring a target, and includes a sensor unit that generates sensing data including background noise data. The background noise data represents noise from a cause other than the target. The sensor device further includes an extraction unit that extracts the background noise data from the sensing data, and a transmission unit that transmits the background noise data extracted by the extraction unit to the external device.

A numerical control system of a machine tool includes an analysis device. The analysis device includes acquisition portions which acquire chronological speed control data when the work is machined and which acquire spatial machined surface measurement data after the machining of the work, a data-associating processing portion which associates the speed control data and the machined surface measurement data with each other, a machined surface failure detection portion which detects failures on the machined surface of the work, an identification portion which identifies the speed control data of failure locations corresponding to the machined surface measurement data of the failure locations, a failure interval detection portion which detects the interval of the failures and a calculation portion which calculates the frequency of vibrations based on a machining speed based on the speed control data of the failure locations and the interval of the failures.
