Claim:
1. An operations management apparatus comprising: a performance information storage unit which stores performance information including a plurality of types of performance values in a system, in chronological order, each of said plurality of types indicating a combination of an apparatus and a performance item in said system; a correlation model generation unit which generates a plurality of correlation models each including a correlation for a pair of different types among said plurality of types of performance values in a predetermined period, which performance values are stored in said performance information storage unit, said pair of different types in one of said plurality of correlation models being the same as said pair of different types in another of said plurality of correlation models; and a model setting unit which selects, from among said plurality of correlation models generated by said correlation model generation unit, a basic model which is a correlation model showing the highest fitting degree and one or more specific models which are correlation models other than said basic model on the basis of a fitting degree of each of said correlation models for said performance information in said predetermined period, and sets time periods on which said basic model and said one or more specific models are applied respectively to failure detection, wherein said predetermined period consists of a set of a plurality of fixed periods, said correlation model generation unit generates individual said correlation models for respective said fixed periods, on the basis of said performance information in said respective said fixed periods, and said model setting unit selects a predetermined number, which is one or more, of correlation models showing the lowest fitting degree in said redetermined period as said specific models.
