基于復雜網(wǎng)絡的串聯(lián)式項目群結構脆弱性分析

摘要： 運用復雜網(wǎng)絡理論研究串聯(lián)式項目群的結構脆弱性。首先,基于串聯(lián)式項目群的拓撲結構及特征,將串聯(lián)式項目群抽象為一個有向加權網(wǎng)絡。繼而運用網(wǎng)絡指標評估串聯(lián)式項目群的結構脆弱性,并進一步探討了網(wǎng)絡拓撲結構特征與其脆弱性之間的關系。研究實現(xiàn)了串聯(lián)式項目群結構脆弱性的定量化評估,能夠有效識別項目群中存在的薄弱環(huán)節(jié),且相關分析表明節(jié)點中心性指標能夠為關鍵節(jié)點的識別提供參考。本研究對于優(yōu)化項目群結構、提高項目群的抗風險能力和保障其順利實施具有重要啟示。
The structural vulnerability of series type program was studied using complex network theory in this paper.The series type program was first abstracted as a weighted directed network,after which network metrics were adapted to assess the structural vulnerability of series type program.And the possible associations between the topological structure properties and vulnerability were then explored through correlation analysis.This paper realized the quantitative evaluation of the structural vulnerability of series type program,and the identification of the inherent weaknesses.It was also found that the node centrality measures could be used to identify the critical nodes.This study has an important enlightenment for optimizing the program′s structure,improving its capability of resisting risks and ensuring its smooth implementation.
