二级供应链成本的系统动力学仿真研究

摘要

In this paper, we used the system dynamics method to build the traditional mode of a two-echelon supply chain practicing VMI as well as the structure of its operational cost, then with the two-echelon supply chain to which the JG Grain Industry was a member as the example, simulated it and at the end, proposed the solution for the optimization of the VMI supply chain model of the company.%运用系统动力学方法构建传统二级供应链以及基于VMI二级供应链运作成本的结构模型，并以黑龙江省JG米业所在的二级供应链为例，进行模拟仿真。通过对两种模式下客户需求变化、供应链总成本及缺货量的比较，建议黑龙江省JG米业采取基于VMI二级供应链模式，并得出制造商分摊零售商库存费用系数范围，同时在基于VMI二级供应链模型中针对订单处理周期及实载率提出优化方案。系统动力学可以较好地反映二级供应链成本系统内因素间的复杂关系，该方法可为二级供应链成本控制提供指导与借鉴。
