摘要： A method is proposed for finding Fault-to-Failure signatures using ordered health states. A data matrix including reference values for a healthy device and degraded values for different degradation levels is processed to determine which data parameters, and more particularly which data parameter time windows, vary from the reference values both with an “order” and a “separation” consistent with ordered health states. The time sample at which a minimum gap between ordered health states is a maximum may determine the window end point. The window start point may be determined by walking back from the end point to the time sample at which the minimum gap crosses a threshold. In this manner, the time window starts when an acceptable order among the health states is first attained and ends when the separation is the strongest.
