Abstract :
The paper by Hwang (IEEE Trans. Reliability, vol. 54, no.1, p. 169-172, 2005) presented structural importance measures in terms of cutsets or pathsets, and investigated how they are related. Hwang´s paper has made contributions to importance measures. However, several errors which cause confusions are found in the paper. This note is to clarify these errors, and discuss the suspicions.
