Abstract: To solve the inventory coordination problem of single-period products under partial demand information, single period products quantity discount scheme based on information entropy was studied. The maximum entropy criterion was applied to forecast the demand distribution. The independent inventory decision and the integrated inventory decision in a supply chain with a retailer and a supplier were discussed, and the quantity discount scheme of supplier was studied. To achieve overall optimization of supply chain system, a quantity discount scheme based on the decision-making entropy-weight was put forward. Based on the integrated decision, this scheme realized maximum system profits and increasing efficiency. Feasibility of the scheme was improved by considering both the possible profit of the two parties before coordination and their marketing competitiveness.
