基于二层规划理论的供应链协调机制

建立了生产商的成本模型和供应商的利润模型,进而建立了供应链的总成本基本模型.在确定的外部需求下,将二层规划理论应用在供应商与生产商的相互协调中.其中,上层是生产商,下层是供应商,生产商与供应商能够互动决策.确定了适当的供应链协调模式.通过仿真计算,验证了协调的供应链运作比简单的供应链运作成本更低.对供应链中的控制变量,即惩罚系数的取值进行了讨论,进一步验证了二层规划理论对供应链的协调效果.

Coordination Mechanism for Supply Chain Based on Two-Hierarchical Programming Theory

The basic models for supplier profit and producer cost and further the total cost model for supply chain are developed. The two-hierarchical programming theory is applied to the interactive coordination between supplier and producer in definite demand where the producer is at upper level and the supplier at lower level and they are interactive in decision-making. Then,a proper model of supply chain coordination is set up using hierarchical programming theory. Simulation results indicate that the solution based on hierarchical programming theory to the problem of supply chain optimization has lower cost and better achievement than the supply chain operation in simple way. In addition,the value of the control variable in supply chain,i.e.,penalty coefficient k is discussed,thus verifying further the important role the two-hierarchical programming theory played in the coordination of supply chain.
