Beschreibung
Zusammenfassung:	A processor-implemented method (400) of assembling a rotatable machine (10) is provided. The machine includes a plurality of blades that extend radially outwardly from a rotor. The method includes determining (402) a geometric parameter for each blade in a row of blades that is relative to a ratio, R of an inlet area and an outlet area of a predetermined volume defined between each pair of blades, determining (404) an initial sequence map for the row of blades that facilitates minimizing a difference of R between circumferentially adjacent pairs of blades, and iteratively remapping (414) the sequence of the blades to facilitate reducing a moment weight vector sum of the rotor to a value that is less than a predetermined value. The rotatable machine is preferably a gas turbine engine.
