Abstract: A failure indication notification system includes an information collection device and an indication notification device. The information collection device collets device information, attribute information, and service information. The indication notification device includes an indication level computation unit that computes an indication level of failure of a device on the basis of the device information, the attribute information, and prediction model information; a notification level computation unit that computes a notification level on the basis of the attribute information and the service information; a determination unit that determines whether or not the notification about the indication of the device failure is to be provided on the basis of comparison between the indication level and the notification level; and a notification unit that notifies an outside of the failure indication notification system of indication information indicating the indication of the device failure.

Abstract: A simulation execution unit (124) performs a simulation with a set time step size, using a simulation engine and using input data for a simulation time slot included in a simulation period as input. A model computation unit (123) performs computation with an estimation model using the input data for the simulation time slot as input. An error calculation unit (125) calculates a difference between a simulation execution result of the simulation time slot and a model computation result of the simulation time slot. A time step size determination unit (126) determines a set time step size in a next simulation time slot based on a result error.

Abstract: A verification device (2) includes: a simulation performing unit (4) to perform simulation; a delay detection unit (5) to detect, as a delay simulation, a simulation being performed by the simulation performing unit (4) and not having real-time responsiveness; a past data accumulation unit (7) containing an accumulation of past data related to a simulation performed by the simulation performing unit (4) in the past; and a past data search unit (6) to search for past data corresponding to a delay simulation when the delay detection unit (5) detects the delay simulation.

Abstract: A similarity degree computation unit (211) computes a similarity degree between each of one or more partial ontologies in a first-system-oriented ontology and a benchmark ontology of a second system, as a similarity degree of each of the partial ontologies. A candidate extraction unit (212) extracts as an ontology candidate from the first-system-oriented ontology, a set of: each of partial ontologies having similarity degrees which satisfy a similarity degree condition; and a partial ontology for linking to each other the partial ontologies having the similarity degrees which satisfy the similarity degree condition. An ontology output unit (214) outputs, when the ontology candidate satisfies a constraint condition, the ontology candidate as a second-system-oriented ontology.
