A differential game model research on dynamic pricing and coordination of fresh agricultural products supply chain based on freshness

For the problem of optimal dynamic pricing and coordination fresh agricultural products supply chain, differential equations related to freshness market needs are constructed, control theory is used solve strategy under centralized decentralized decision-making, i.e., selling price preservation input. The equilibrium results two scenarios also compared. comparison finds that scenario leads low overall chain profits, based on which a two-part contract proposed coordinate operating companies. show effectiveness directly impacts pricing, does not necessarily lead high prices for produce due ‘double marginal effect’. contracts can successfully chain. increases ability suppliers, while operational inefficiencies, contrary, decrease ability.
