Research on Supply and Demand Matching Strategy of Power Grid Material Agreement Inventory Based on Gale-Shapley Algorithm

Aiming at the supply and demand matching problem between multiple suppliers and multiple power grid companies under the power grid material agreement inventory procurement model, the transaction demand of power grid companies and suppliers is analyzed first, then the utility evaluation system and preference utility function of both parties are constructed, and finally the Gale-Shapley algorithm is used to establish a supply and demand matching model for agreement inventory based on preference ordering. Six sets of real data were used for bidirectional matching to verify the rationality of the matching results. The results show that the grid company's satisfaction with the matching results reaches 92%, and the supplier's satisfaction with the matching results reaches 95%. The agreement inventory supply and demand matching model based on the utility evaluation system and Gale-Shapley algorithm can fully reflect the actual demand of power grid companies and the delivery willingness of suppliers, and can effectively improve the accuracy and stability of the agreement inventory supply and demand matching results for power grid materials.
