构建随机市场需求环境下供应商持股制造商的供应链模型,分别给出供应商的最优批发价格决策与制造商的最优订货量决策。研究表明,供应商对制造商的持股虽然减弱了但是并没有消除供应链系统中的双重边际效应。随后,设计了基于回购策略与补贴策略的供应链协调契约。在该协调契约下,供应商能够通过调整契约中的批发价格,以任意比例与制造商分享系统期望利润。即供应链系统可以实现完美协调。
The supply chain model of supplier-holding manufacturer under stochastic market demand environment is constructed, and the optimal wholesale price decision of suppliers and the optimal order quantity decision of manufacturer are respectively given. Research shows that the supplier’s ownership of the manufacturer is weakened but it does not eliminate the double marginal effect in the supply chain system. Subsequently, a supply chain coordination contract based on repo strategy and subsidy strategy was designed. Under this coordination contract, the supplier can share the expected profit of the system with the manufacturer in any proportion by adjusting the wholesale price in the contract. The supply chain system can achieve perfect coordination.
