Abstract

Network reliability can be improved effectively by improving most important key link that has the largest value of Probability Importance. But use of it results in that better reliable link should be more improved and this is irrational. Thus this article proposed newly developed Criticality Importance and compare the network performances improved by both importance indicators. The criticality importance considers the fact that it is more difficult to improve the more reliable links than to improve the less reliable links. Both characteristics are quantitatively discussed with small network.
