【摘要】：為揭示海運(yùn)航線網(wǎng)絡(luò)的特征,評(píng)估港口失效對(duì)網(wǎng)絡(luò)連通性的影響,基于復(fù)雜網(wǎng)絡(luò)的相關(guān)理論,對(duì)海運(yùn)航線網(wǎng)絡(luò)的結(jié)構(gòu)特征進(jìn)行分析,并考察了港口在不同失效模式下網(wǎng)絡(luò)連通性的變化.研究結(jié)果表明,海運(yùn)航線網(wǎng)絡(luò)同時(shí)具有較小的平均路徑長(zhǎng)度和較大的集聚系數(shù),具有小世界效應(yīng),度分布與冪指數(shù)分布擬合程度較好而具有無(wú)標(biāo)度特征;在節(jié)點(diǎn)隨機(jī)失效下網(wǎng)絡(luò)的抗毀性較強(qiáng),而在選擇失效下,網(wǎng)絡(luò)的連通性較差;少數(shù)樞紐港口對(duì)海運(yùn)航線網(wǎng)絡(luò)的連通性起著關(guān)鍵的作用,應(yīng)當(dāng)切實(shí)保障這類港口的正常、高效運(yùn)行,同時(shí)需加強(qiáng)樞紐港口與普通港口之間的連接,完善網(wǎng)絡(luò)結(jié)構(gòu).
[Abstract]:In order to reveal the characteristics of seaborne route network and evaluate the influence of port failure on network connectivity, the structural characteristics of seaborne route network are analyzed based on the theory of complex network.The change of network connectivity in different failure modes is investigated.The results show that the seaborne route network has smaller average path length and larger agglomeration coefficient and has small world effect. The degree distribution fits well with power exponent distribution and has scale-free characteristics.The network has strong survivability under the random failure of nodes, but poor connectivity under the selected failure. A few hub ports play a key role in the connectivity of the maritime route network, and the normal of these ports should be ensured.Efficient operation, at the same time need to strengthen the junction between the hub port and ordinary ports, improve the network structure.
