Research On SF Express Company Super Network Optimization Based On Time Threshold

Express industry is undoubtedly an emerging industry and a sunrise industry in the economic globalization today, who plays a pivotal role in the courier industry, express delivery companies in the market is also facing greater and more severe challenges, the market needs faster, more diverse service delivery service, with the progress of science and technology on society and express industry has put forward higher requirements. Therefore reduce costs and improve efficiency to become placed in front of a major problem courier companies, courier network system is a multi-target, multi-dimensional and multi-level super-network system, simply can not meet the physical level optimization Express needs to SF’s case courier network is an organization managed by the branch subnets dimension units to transit centers and business units management network, how to deal with the cost and efficiency of this contradiction, achieve optimal efficiency in meeting the different constraints conditions, thereby from extensive management to fine management, to express the survival and development of enterprises and the whole industry is of great significance.Firstly, the background and significance of the research, discusses the research status of the courier industry network optimization, theory foundation of the article including ultra networking concepts and time threshold definitions were consolidated and summarized, and construction and for the following model Analysis of the foundation.Secondly, the status of SF Express conducted a survey, analysis of SF’s business model, the company’s distribution network and the status of SF’s transport network, pointing out at the lack of development on the basis of cross-sectional depth of the company’s operations on the network.Again, based on the basis of SF’s existing business model, and points out SF’s distribution system is a complex network of super-network systems, including those based on cost-optimized branch dimensions of business management based on the subnet and transit center at the core of maximum efficiency business management subnet, using mathematical modeling thought, was established to consider the cost and efficiency of a multi-dimensional, multi-target, multi-constrained company SF super network model and for the model proposes an improved algorithm for solving target Floyd equation.Finally, through the acquisition of 23 domestic cities SF company cost data, respectively courier super network model to explore the optimal target subnetwork same time, by increasing the thresholds at different times to verify the validity of the model, it obtained internal cost and efficiency of interaction mechanism, and the company’s existing network deficiencies SF proposed rationalization recommendations for improvement.
