Abstract: A system and method detect and forecast a performance degradation of a M-system. The method includes collecting data regarding the M-System during a period of time P1, storing the collected data in a database and analyzing the collected data collected during the period of time P1 by an elaboration routine containing two distinct elaboration phases. Namely, a first elaboration phase, where a performance analysis system selects among the collected data a set of data to be analyzed and removes any noisy data from the set of data and a second elaboration phase, where the performance analysis system correlates, for the set of data, data belonging to different sources, but generated at a same time within the period of time P1 to create M-System state data snapshots characterizing the M-System at different times Ti within the period of time P1. Finally, a model for the M-System is generated from input datasets.

A job schedule is generated based on an optimization function that minimizes total energy cost for all the machines during a time horizon based on a summation of energy cost at each time step between a start time and an end time. The energy cost at each time step is a summation of (a) a first energy cost associated with each machine in sleeping mode during the time step, (b) a second energy cost associated with each machine in stand-by mode during the time step, and (c) a third energy cost associated with each machine in processing mode during the time step.
