The Model And Application Reseach On Logistics Distribution Network Based On Effective Path

In recent years,with the development of economic globalization and e-commerce,the third party logistics enterprises are entering the rapid development stage,logistics industry urgently need high efficiency and low cost in the operation process of logistics distribution network to adapt the increasing goods.In real life,many path seems near but it take much time and more than the it take on the far path due to traffic congestion,so in this paper,we guessed there are effective paths in logistics distribution network,and the others are not effective,we think the effective paths are their best paths.Based on the effective paths proposed,we study the logistics distribution network construction.With the analysis of the compositions and the structure of logistics distribution network,we study the logistics distribution network model that consists of multiple node and single distribution center.In the actual traffic networks,there are many uncertain factors,such as road accidents,congestion problems an so on,these problems especially happen in the road that take high traffic flow,which affect the distribution and would produce more problem in logistics networks.Therefore,in this paper,we consider the road failures to study the distribution network with multiple logistics nodes and single distribution center.Based on my professional knowledge,the study on logistics and networks during the postgraduate,and the reference,we study three point as the follows:(1)Research on the model of logistics distribution network,we give an analysis of the logistics network construction foundation in order to better close to the actual logistics operation.We analyze the affection of the time and the distance between every two nodes on the efficiency and cost to choose the effective distance.We treat the logistics nodes as the nodes in the network,and see the effective distance as the edges to build the distribution network.(2)Logistics distribution network model based on the effective path and consider the road failure.We analyze the harmfulness of realistic traffic network breakdown and the effects to the best path selection,and simulate the deliberate attack triggered breakdown in roads and the first phase reproduction process.We use the change of effective distance to quantify the effects on network.We build the model to relocate distribution center,plan the distribution routs,to reconstruct the distribution network with multiple nodes and single distribution center logistics.(3)Analysis of SF express logistics distribution network.Through the searching for SF express delivery node in Shenyang by map software and fieldwork measurement,and caculate the time and distance between the nodes to get the effective distance and effective path between nodes in method of Floyd,we construct the distribution networks respectively in considering the breakdown on the road and no breakdown.We have a research on logistics distribution network model proposed in this paper,which will enrich the study field of the the existing content logistics system.The logistics distribution network model and the model with considering the breakdown of the traffic can be applied on the logistic management and supply chain planning,to reduce the effect of the breakdown on distribution center's distribution and improve the reliability of the logistics distribution center.
