三级供应链中信息共享的价值研究

摘要

Based on Lee HL' s model ,we establish the model of a tri-echelon supply chain to research the value of information sharing. We focus on the value of the third echelon of the supply chain, that is, the supplier. We use matlab to simulate the impact of the parameters. Studies have shown that information sharing can reduce inventory levels and expectations of the supplier's costs, and create value for the supplier. The supplier under the condition of the manufacturer to participate in information sharing is better than the manufacturr not to participate, and the rde of the manufacturer in demand information sharing of Tri-echelon supply chain is essential.%通过建立模型研究三级供应链中信息共享的价值.研究建立简单的三级供应链模型,在Lee H L,So KC,Tang C S模型的基础上重点研究并量化了第三级即供应商共享需求信息所带来的价值,并对影响参数进行matlab仿真实验.研究表明信息共享可以降低供应商库存水平和期望费用,给供应商带来价值；供应商在制造商参与信息共享的条件下要比不参与时更优,制造商在三级供应链需求信息共享中地位至关重要.
