A method for calibrating a physical test cell includes the steps of: determining a set of inputs to be provided to the physical test cell based in part on a set of historical test data; providing the inputs to the physical test cell and receiving a set of outputs associated therewith, wherein the providing includes implementing a sequential space filling sampling procedure to substantially cover a region defined by the set of historical values; creating a virtual test cell comprising one or more response surfaces based on the set of outputs; and interrogating the virtual test cell to determine a calibration relationship between at least one of the inputs and at least one of the outputs. Smooth Kriging may be used to determine the virtual test cell.
