Centralized Inventory Model Simulation And Optimization Of Reverse Logistics In Xinhua Bookstore

This thesis analyzes and optimizes the inventory management of reverse logistics in Xinhua bookstore.Based on the deepening of China's supply-side reform,the book industry is also undergoing continuous self-innovation,but it has not received enough attention in the inventory management of reverse logistics.The book market coverage rate of Xinhua bookstore is more than 90%,book sales account for more than half of the country,is the largest book publisher and mid-plate business.The reverse logistics of Xinhua bookstore can also be called the reverse logistics of books,which refers to the process of secondary distribution or depreciation of books returned to each branch by the provincial store center of Xinhua bookstore.The main problem of the reverse logistics of Xinhua bookstore is inventory management,and the return rate is higher than that of the general retail industry.Therefore,how to reduce the inventory cost of reverse logistics and improve the management level of reverse logistics has become one of the major tasks of Xinhua bookstore.Aiming at the problem of inventory management of reverse logistics in Xinhua bookstore,the main research contents of this thesis include: first,sorting out domestic and foreign literature,sorting out the research on reverse logistics and centralized inventory management,and summarizing the deficiencies of the research on reverse logistics of books.Second,it expounds the reverse logistics of Xinhua bookstore,summarizes and finds its inventory status,existing problems and causes.Third,it introduces the significance,necessity and basic steps of logistics system simulation,which provides theoretical support for the inventory system simulation of reverse logistics in Xinhua bookstore.Fourth,the centralized inventory management model and decentralized independent decision-making inventory model of reverse logistics in Xinhua bookstore are established,and the comparison verifies that the former is superior to the latter in reducing inventory cost.Fifth,through Flexsim-based simulation,the two-level inventory model of Jiangxi Xinhua bookstore is simulated,and the empirical analysis also proves that the centralized inventory management model is better than the decentralized independent decision-making inventory model.The sixth part is the summary of the research content and the future research direction of reverse logistics.The purpose of this article is to simulate and optimize the centralized inventory management model of Xinhua Bookstore's reverse logistics,to promote the development of the domestic book industry and to explore new profit growth points.
