摘要:
为分析需求与供货可靠性相关关系及需求更新对采购策略的影响,考虑制造商可先后向紧密和松散供应商采购某部件,建立两阶段双渠道采购模型。通过分析三阶海赛矩阵证明最优采购策略存在且唯一,并求得最优解。研究结果表明:制造商的采购决策服从具有联动效应的边际分析规则;需求和供应可靠性的波动显著影响采购决策,其相关关系令制造商利润减少;即使紧密供应商部件价格更高,风险中性制造商仍可能向其采购,以免失去销售机会。
Abstract:
To analyze the correlations of demand and supply reliabilities and the effects of demand updates on procurement decisions,a twostage dual sourcing framework is built considering that a manufacturer can order from collaborative and armslength suppliers.The existence and uniqueness of the optimal procurement decision are proved by analyzing a threedimension Hessian matrix,and the optimal solution is derived.The research results show that the procurement decisions of manufacturers obey a rule of correlated marginal analysis;the fluctuations of demand and supply reliabilities have notable impacts on the procurement decisions,and their correlations reduce the manufacturers’ expected profits;riskneutral manufacturers may procure from collaborative suppliers even though they have higher wholesale prices,so as to avoid missing potential sales opportunities.
