摘要

An outline of the multi-fault diagnostic observation concept is presented in the paper. Starting from the commonly used Singular Value Decomposition (SVD) it is shown, that it is equivalent to the modern version of Principal Component Analysis (PCA). During the development of the concept of multi-fault observation several indices and measures obtained from SVD were tried, and some seem to bring the success. This problem is also addressed in the paper and illustrated by real examples taken from railroad Diesel engine condition monitoring.
