考虑紧密和松散供应商的双渠道采购决策研究
Dual Sourcing Procurement Decisions Considering Collaborative and Arms-length Suppliers
摘要
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.关键词
