Abstract
Damage rate data associated with a plurality of positions on a machine can be used construct a damage rate covariance matrix, from which a matrix of modes can be derived. A subset of modes from the matrix of modes can be identified, and damage rate monitoring positions on the machine can be selected by identifying a subset of the plurality of positions on the machine that maximize a determinant associated with the matrix of modes using D-optimal row selection.
