摘 要：市場經(jīng)濟充分發(fā)展，行業(yè)競爭加劇，物流成本是競爭的焦點之一。為了更好提高物流配送效率、降低物流成本，對配送網(wǎng)絡(luò)及節(jié)點布局進行研究尤為重要。本文選取非常態(tài)壟斷快消品這一特殊商品的物流配送網(wǎng)絡(luò)開展研究，基于復(fù)雜網(wǎng)絡(luò)理論構(gòu)建了1065′1065的鄰接矩陣，對其配送網(wǎng)絡(luò)及網(wǎng)絡(luò)特性進行分析，并構(gòu)筑配送網(wǎng)絡(luò)的拓撲模型，以揭示該復(fù)雜網(wǎng)絡(luò)的點、邊、度與度分布、網(wǎng)絡(luò)直徑、平均路徑長度、聚類系數(shù)等整體特性，通過點度中心性、接近中心性、中介中心性等指標探尋網(wǎng)絡(luò)中的重要節(jié)點。以重慶卷煙配送網(wǎng)絡(luò)為例對該方法進行了驗證，研究結(jié)果可以指導(dǎo)對關(guān)鍵節(jié)點進行重點保護，以避免或減少網(wǎng)絡(luò)遭遇破壞時的損失；有助于其物流網(wǎng)絡(luò)節(jié)點的布局及優(yōu)化，降低物流成本，與市場競爭接軌。

Abstract: With the development of market economy and the increasing competition in the industry, logistics cost is one of the focuses for competition. In order to improve the efficiency of logistics distribution and reduce the logistics cost, it is very important to study the distribution network and the layout of nodes. We select the logistics distribution network of non-conventional Monopoly FMCG, based on the complex network theory, construct the adjacency matrix of 1065′1065 and the topology model, study its distribution network and complex network characteristics, in order to reveal the complex network Degree, Diameter, Averagepath length, Clustering coefficient and so on. And then, put forward to evaluate the node importance for three indicators in Degree centrality, Closeness centrality and Betweeness centrality. Taking the Cigarette distribution network as an example, verify the method. The research results can guide the protection of key nodes, in order to avoid or reduce the losses suffered damage network; and contribute to the layout and optimization of its logistics network nodes, reducing logistics costs, helping to participate in market competition.
Key words: complex network; non-conventional; monopoly FMCG; Distribution network; network characteristics; important nodes
