Claim Text:
1. An operations management system, comprising: a correlation model storing unit which stores a correlation model which indicates a correlation among plural types of performance values, for each of plural systems; an analysis order storing unit which stores a sequence in said plural systems for carrying out detection of a correlation destruction; an analysis unit which carries out, in each of plural time periods, detection of whether said correlation destruction of said correlation included in said correlation model of each of said plural systems is caused by use of performance values inputted for said each of plural time periods, according to said sequence; and an order control unit which updates said sequence in said each of plural time periods, in such a way that said detection for a system on which said correlation destruction has been caused carried out earlier than said detection for a system on which said correlation destruction has not been caused, wherein said order control unit determines said sequence based on a result of said detection of whether said correlation destruction is caused in each of said plural systems, wherein said order control unit determines said sequence by use of a degree of abnormality which is derived from at least one of a degree of correlation destruction calculated on a basis of a number of destructed correlations included in said result of said detection, and a degree of similarity between said result of said detection obtained when a fault is caused in said system and said result of said detection on said inputted performance values, and wherein, in a case that said detection has not been carried out for one of said plural systems in one of said plural time periods, said order control unit sets a value greater than said degree of abnormality which was calculated in a time period in which said detection was carried out for said one of said plural systems, before said one of said plural time periods, to said degree of abnormality of said one of said plural systems.
