Abstract
Sensor data immediately after the issuance of an alarm does not exhibit the peculiarity of a failure, with the result that the wrong component is sometimes erroneously identified as the failure component. A failure component identification unit provided in a maintenance device collects an alarm issued when a measurement value exceeds a range of a measurement threshold value in an apparatus being a maintenance target. The failure component identification unit identifies the failure component on the basis of the measurement value exhibiting a condition indicating a peculiarity of the failure. An identification reliability determination unit determines the reliability of the component identification result obtained by a failure component identification unit. When it is determined that the reliability of the identification result is low, a presentation unit presents measures to enhance the reliability of the identification result until the measurement value exhibits a condition indicating the peculiarity of the failure.
