Research on Power Grid Equipment Supply Chain Based on Lateral Transshipment Mechanism and Transshipment Coordination Center

Power grid industry is the foundation of national economic development. Ensuring the reliable supply of power materials and equipment, building a supply chain with industry characteristics have become the focus of power grid enterprises. Therefore, this paper takes a typical three-level power grid equipment supply chain as the research object. The supply chain is composed of an equipment seller or agent with an online sales platform, several different provincial warehouses and city-level members. Through transfer between peers and replenishment between upstream and downstream, it can effectively cope with the daily operation needs of the power grid and various emergency support needs. This paper studies and constructs a hybrid strategy that integrates the lateral transshipment mechanism and the transshipment coordination center mechanism. The lateral transshipment mechanism realizes the inventory sharing among online and offline, upstream and downstream supply chain members and supply chain members at the same level, while the coordination center realizes the inventory surplus and shortage information sharing among supply chain members, and centrally and uniformly coordinates the transshipment and distribution of inventory, thus turning the complex many-to-many transshipment relationship among members into a one-to-many transshipment relationship, efficiently matching supply and demand, and effectively simplifying the complex form of transshipment price function, while making the supply chain performance approach the optimal value during coordination.
