低碳供应链协同技术创新的微分对策模型

Differential decision model for collaboration technology innovation in low carbon supply chain

建立由供应商和制造商组成的低碳供应链协同技术创新的微分对策动态模型,运用汉密尔顿-雅可比-贝尔曼方程给出不同决策模式下制造商和供应商的协同技术创新策略,以及协同合作模式下最优利润分配比例的取值范围。研究结果表明协同合作决策模式下,制造商和供应商的低碳技术创新努力程度以及供应链总体利润均严格优于在非合作决策模式下的相应值,帕累托最优的利润分配比例由技术研发成本和技术创新对产品减排绩效的贡献共同决定。

In view of collaboration technology innovation decision making problems between suppliers and manufactures in the secondary supply chain, the dynamic decision strategies of suppliers and manufactures on different decision are given by Hamilton-Jacobi-Bellman equation. The results show that, in the collaborative decision making mode the low carbon technology innovation level of manufacturer and supplier and the overall supply chain profits are much better than the corresponding values in the non-cooperative model. The profit distribution coefficient of Pareto optimality is determined by the cost of R＆D and the contribution of technology innovation on product emission reduction performance.
