Express terminal logistics distribution is a logistics activity in which a logistics service provider delivers express parcels directly from the last distribution outlet to consumers in order to meet the end customers of the logistics link. In recent years, with the sharp increase in the amount of express delivery, because the residents and students are in class, it is impossible to directly deliver the express delivery to the customers, and the community unit also limits the security management of express delivery, and gradually there have been contradictions. For random entry and exit, it is necessary to perform multiple express delivery before frequent delivery, which has a great impact on the efficiency of terminal logistics and customer satisfaction. In order to reduce the difficulty of terminal logistics, this paper proposes a terminal circulation method established between the urban circulation center and the customer's terminal circulation network, that is, from the urban circulation center to the terminal circulation network and the customer's circulation method. The hub station between the enterprise distribution center and consumers will cover the entire community, office buildings, schools and other distribution terminals. Customers can freely choose the method and time of receipt to reduce the costs incurred when the two parties deliver the package and conduct the transaction. Time is more flexible.This paper focuses on the development status of terminal logistics distribution in domestic express delivery industry, and gives an overview of terminal logistics distribution and immune algorithms, and analyzes the significance of terminal delivery in express delivery companies. At the same time, for the problem of the location layout of the terminal distribution network of the express delivery company, a location model considering the distribution volume and distance is established, and the problem-solving ideas and steps of the immune algorithm are introduced. Through the development status of SF express company as the background of site selection research, master the relevant data of SF express company's terminal distribution site selection, combined with the development trend of terminal distribution, and apply immune algorithm ideas to solve the results in Matlab environment. Finally, it puts forward reasonable suggestions for the location selection of the terminal distribution network of SF Express.
