1. A method for self-optimizing, in real time, a machine relative to a specific performance characteristic in response to variations on a prescribed number m of variables comprising:

  • selecting a statistical design which prescribes the number n of tests and the exact design matrix in which the test level of each of the m variables is specified for all the n tests;

    according to the design matrix simultaneously sensing and adjusting to their respectively specified test levels all said m variables at a specific time instant;

    recording and storing the value of the specific performance characteristic in response to all said m variables at their respective test levels for this specific time instant;

    sequentially and repeatedly sensing and adjusting the conditions of all said m variables according to the design matrix at n-1 substantially consecutive time instants within minutes subsequent to said specific time instant;

    sequentially and repeatedly recording and storing the n-1 values of the specific performance characteristic in response to all said m variables at their respective levels for the n-1 subsequent, consecutive time instants;

    analyzing the n sets of recorded values and combinations of levels of said variables to determine the functional relationship between said variables and said specific performance characteristic;

    from the functional relationship determining the singular combination of the conditions of said m variables that gives optimum value for the specific performance characteristic for the particular time instants and condition, environment, and service requirements of the machine; and

    setting the conditions or levels of said m variables at their respective, thus-determined conditions.
