Two-stage supply chain coordination method based on quantity discount contract under information symmetry condition

Abstract

The embodiment of the invention provides a two-stage supply chain coordination method based on a quantity discount contract under information symmetry condition. Under the condition of the two-stage supply chain information symmetrical, when the purchasing amount of a retailer exceeds the standard purchasing amount, a manufacturer gives a certain price discount. The method includes the steps of establishing a standard purchasing decision-making model and a standard production decision-making model respective for a two-stage supply chains before coordination, solving the models to obtain the minimum cost and the maximum profit to serve as measurement standard for the subsequent coordination, establishing a coordinated mathematical model, determining whether the cooperation conditions of thetwo parties are met or not based on the cooperation condition, and obtaining the optimal discount rate, purchasing quantity and production quantity by using Nash equilibrium solution. Better market benefits can be obtained by using the two-stage supply chain, and long-term cooperation relation of two parties can be maintained.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a secondary supply chain coordination method based on a quantity discount contract under the condition of information symmetry. Background technique [0002] Usually, in the secondary supply chain composed of retailers and manufacturers, retailers and manufacturers have different decision-making objectives. When making decisions, they only consider their own interests, while ignoring the interests of other member companies or the entire When the benefits of the system are not met, it will often reduce the overall profit of the supply chain and make the system out of balance. And when all decisions in the system are decided by the same decision-making subject, the overall profit of the system can reach the maximum, thus achieving the optimal state. [0003] Most of the current studies on the coordination of secondary supply chains are based on single-period or continuous dem...
