考虑原产地规则的跨境纺织供应链网络设计

Design of global textile supply chain network with rules of origin

为了实现纺织企业跨境供应链网络的利润最大化,在考虑原产地规则的基础上,综合考虑工厂布局、供应商选择、生产及运输等重要决策,构建了最大化利润的混合整数非线性规划模型,并将其等价转化为可最优求解的线性规划模型,设计相应的Benders分解算法实现对模型的最优求解。最终通过仿真,针对不同的贸易制度安排,特别是即将实施的“区域全面经济伙伴协定”中的区域累积原产地规则,研究了其对企业跨境供应链网络设计决策及利润的影响。研究结果表明:随原产地规则比例要求的提高,会导致企业利润的下降,而在区域累积的原产地规则下,企业能够更自由地进行选址及生产采购决策,有利于实现全球供应链的最优配置。

In order to maximize the profit from global supply chain networks of textile companies,a mixed integer nonlinear programming model based on the rules of origin was developed,where the critical decisions,such as factory layout,supplier selection,production and transportation,were taken into account.For optimization,the proposed model was equivalently linearized into a tractable linear model and an algorithm based on Benders decomposition was designed.The experiments were implemented based on various trading regulation arrangements,especially the regional cumulative rule of origin involved in the coming Regional Comprehensive Economic Partnership agreement.Their influences on the companies′cross-border supply chain network design and profits were investigated.The results show that the increase of the proportion requirement for rules of origin will lead to the decline of enterprise profits,and under the regional cumulative rules of origin,enterprises can make more free decisions on site selection and production and procurement,which is conducive to the realization of the optimal allocation of global supply chain.
