1. A method for the evaluating and modifying the operating conditions of a machine or an installation, comprising the steps of:
- measuring at least one parameter a number of times to create a database, which comprises values (x1,y1) to (xn,yn) of the parameter;
determining an extrapolation range, xs;
performing an extrapolation in the range xs;
determining a measure of quality, K, of the extrapolation calculated on the basis of the database wherein K is a function of at least two variables taken from the group consisting of V, Δ
I, S, C, with V being a ratio of the value range of the database to the extrapolation range, xs which is determined by xs>
x1, xn with Δ
I being the x uncertainty of the adjustment curve in the x direction, with S being continuity as a measure of the change in the y values in the database and with C being the time constancy of the extrapolation; and
controlling the parameter value so that the value will be retained within a limit,wherein the evaluation of the operating conditions is used to optimize the operation of the machine or the installation.

Abstract
A method for evaluating and modifying the operating conditions of a machine or an installation includes measuring at least one parameter a number of times to create a database, of the parameter, determining an extrapolation range, performing an extrapolation in the range, and determining a measure of quality, K, of the extrapolation calculated on the basis of the database. K is a function of at least two variables. The parameter value is controlled so that the value will be retained within a limit.
