【摘要】 研究了含两个销售期的二级供应链,分析了零售商在当前销售期的提前采购决策、供应商在未来销售期的开通直销渠道决策。研究发现:零售商通过提前采购可以压低供应商在未来的批发价,因此当库存持有成本较低时,提前采购使零售商获利。但是,受供应商直销渠道策略的影响,零售商有可能在库存持有成本较高时也提前采购,反而因此遭受损失。然而,提前采购的战略意义在于,它能阻止供应商开通直销渠道,使零售商免于更大的损失。因此,零售商明知提前采购损害其利益仍有可能采用该策略,这是两害相权取其轻的结果。更多还原

【Abstract】 In this paper, we studied the two-echelon supply chain containing two selling periods and analyzed the retailers’ purchasing in advance at the present selling period and the suppliers’ direct selling in the following selling period. The results showed that through purchasing in advance, the retailers could lower the suppliers’ wholesale price. Hence when the inventory holding cost was low,retailers could benefit from the purchasing in advance. However, affected by suppliers’ direct selling strategy, retailers might purchase in advance even when the inventory holding cost was high, which might cause a great loss. Nevertheless, the purchasing in advance could prevent suppliers from opening direct selling channels and help retailers avoid greater losses. Retailers might still use this strategy even they knew it damaged their interests because this loss was lighter than that one.更多还原
