Abstract : the complexity of tree set analysis for network was compared with that of minimum cut set analysis . if was illustrated by an example that the analysis method based on minimum cut set is the best approach for the availability analysis of network 摘要:對(duì)網(wǎng)絡(luò)分析的樹(shù)集分析法與最小割集分析法的復(fù)雜性進(jìn)行了比較,并示例說(shuō)明以最小割集為基礎(chǔ)進(jìn)行網(wǎng)絡(luò)可用性分析是最佳的技術(shù)途徑。
