Abstract: With the densification of courier dot density, the structure of network is directly related to the courier company's operating cost and service level. Focusing on the market of the city express, we change the affiliation of outlets without changing the site size of the existing outlets, combine the hub and spoke network structure to enhance its express delivery time and optimize its cost and resource investment. A hub location model with branch constraint is developed with the objective of minimizing transportation costs. And an efficient tabu search algorithm is designed to solve the problem. Finally, the corresponding solution is conducive to integrating resources and the formation of economies of scale, and the division management basis is given to avoid the confusion of management and operation due to the complex network structure. In the long run, this will help save operating costs, increase the flexibility of its delivery network, and reduce the difficulty of operational management.
