Abstract
A method is provided for evaluating stall/surge margin of a machine of interest. The method includes identifying a vital factor where each the vital factors corresponds to operation of the machine of interest. Raw data relating to the vital factor is provided. A contribution of the vital factor to the stall/surge margin is determined from at least the provided raw data. The contribution of the vital factor to the stall/surge margin is statistically analyzed. A stall/surge margin is allocated based on the statistical analysis of the contribution of the vital factor. An operating limit line is defined based on the allocation of the stall/surge margin.
