基于博弈论的供应链价格协调研究

在博弈论框架下针对一个由单一买方和单一卖方组成的供应链系统,研究了在需求具有价格弹性时两阶段供应链的定价协调问题,该问题以整个供应链渠道的总利润最大化为目标,把买卖双方的个体理性作为约束条件.研究了两个非合作博弈模型和一个合作博弈模型,通过比较分析建立了可转移效用(返利)形式的协调机制,该机制能有效改善供应链渠道和成员的利润,数值实例表明该协调机制达到双赢的结果是稳定可行的,对供应链协调具有指导意义.

Price Coordination Analysis of Supply Chain Based on Game Theory

Aiming at a supply chain system constituted by one buyer and one vendor,the problem of coordination mechanism under elastic demand of the price was analyzed in the paper based on the game theory.The purpose is to maximize the gross profit for the whole supply chain channel under the constraint of individual ration.Two non-cooperative static game models and one cooperative game model were proposed.After comparisons and discussions in detail,a feasible cooperative coordination mechanism of transfer payment scheme is then obtained,which can improve effectively the profits of both the members and the supply chain channel.The availability and feasibility about the mechanism is identified by numeric analysis.The results can provide guiding suggestions to the supply chain.
