MALFUNCTION ANALYSIS APPARATUS, MALFUNCTION ANALYSIS METHOD, AND RECORDING MEDIUM
First Claim
1. A malfunction analysis apparatus comprising:
- a malfunction-contribution degree calculator obtaining a malfunction-contribution degree, which indicates a degree that individual malfunctions (hereinafter, referred to as malfunctioning elements) contribute to a malfunctioning of an object being analyzed, based on a relative relationship between data to be analyzed of which elements have values generated based on values of a plurality of indicators for the object being analyzed, and representative values for the plurality of indicators corresponding to a plurality of malfunctions respectively;
a malfunctioning elements specifier specifying the malfunctioning elements being occurred, based on the malfunction-contribution degree obtained by the malfunction-contribution degree calculator;
a cause indicator specifier specifying, when a malfunction is occurred which is a combination of the malfunctioning elements, an indicator which is estimated as a cause of the malfunctioning elements specified by the malfunctioning elements specifier, based on the representative values of the plurality of indicators and the values of respective elements of the data to be analyzed; and
an outputter outputting at least one of the malfunctioning elements specified by the malfunctioning elements specifier and the indicator specified by the cause indicator specifier.

Abstract
A malfunction analysis apparatus (100) is provided with a malfunction-analysis processor (107), an attribute-extraction processor (108), and an outputter (105). The malfunction-analysis processor (107) obtains a malfunction-contribution degree, which indicates a degree that individual malfunctions (to be called malfunctioning elements, hereafter) contribute to the malfunctioning of the object being analyzed, on the basis of the relative relationship between the data to be analyzed that has, as elements thereof, values generated on the basis of a plurality of indicator values of the object being analyzed, and representative values for the plurality of indicators corresponding to each of the plurality of malfunctions. Then, the malfunctioning elements being generated is specified, on the basis of the obtained malfunction-contribution degree. The attribute-extraction processor (108) specifies, when a malfunctioning is taking place that is a combination of the malfunctioning elements, the indicators that are estimated as the cause of the specified malfunctioning elements, on the basis of the representative values of the plurality of indicators, and the values of each of the elements of the data to be analyzed that was stored. The outputter (105) outputs the specified malfunctioning elements and/or the indicators.
