An operations management apparatus is provided which acquires performance information for each of a plurality of performance items from a plurality of controlled units, and manages operation of the controlled units, The operations management apparatus includes a correlation model generation unit and a model searching unit. The correlation model generation unit derives a correlation function between a first element and a second element of the performance information, generates a correlation model between the first element and the second element based on the correlation function, and obtains the correlation model for each element pair of the performance information. The model searching unit searches for the correlation model for each element between an input element and an output element among elements of the performance information in series, and predicts a value of the output element from a value of the input element based on the searched correlation model.
