基本供应链库存设计研究

为了探索供应链库存设计方法,分析了现有库存设计模型在方法转换、目标函数处理和费用非线性方面的技巧。提出了混合二阶段的基本供应链结构模型和基本库存决策问题以及0-1混合整数规划数学模型,同时给出了基于运输规划的求解方法和步骤。该方法解决了库存建设费用给目标函数带来的0-1变量的问题,考虑了规模经济带来的物流成本非线性的问题,解决了同时存在中转和直送的混合二阶段库存决策问题。实证分析进一步说明了该方法的方便性、实用性和有效性。

Study on Inventory Design of Basic Supply Chain

The paper analyzed the technique of Inventory Design model in transformation way and disposal object function and expense nonlinearity.For Design Inventory of Supply Chain, the mix 2-stage of basic Supply Chain structural model and the decision-making problems of Inventory and the 0-1 mix-integer programming model were described,the method and process based on transportation programming were also put forward.Because of Inventory construct cost 0-1 variable problem in object function was resolved,and because of Scale economy the logistics cost nonlinearity problem was considered,the mix 2-stage decision-making problems of Inventory existing transfer and highway simultaneity were resolved. The demonstration research also indicated that the method is convenient and practicable and effective.
