| 中文摘要 |
| 基于双源采购, 考虑一个零售商、一个不可靠供应商和一个可靠供应商组成的生鲜农产品供应链. 零售商面临货架保鲜敏感的随机需求, 不可靠供应商面临产出随机, 生鲜农产品的流通损耗由供应商承担. 首先给出零售商最优订货保鲜联合决策存在的条件. 然后分析两个供应商的响应式定价决策, 分别给出两个供应商最大化市场份额的批发价阈值. 研究发现: 零售商提高保鲜努力水平会导致期望收货量下降; 无论哪个供应商提高其批发价, 都会导致零售商在该供应商处的订货量下降, 并提高另一个供应商的订货量; 产品存活率只对零售商的订货决策存在影响, 而对保鲜努力水平和期望利润无影响; 存活率下降会使得不可靠供应商的利润上升, 可靠供应商的利润下降.最后, 通过探讨零售商只选择一家供应商的扩展模型发现, 成本对于零售商的选择具有决定性作用. |
| 英文摘要 |
| In the presence of dual-source order, this paper investigates a fresh produce supply chain composed of a retailer, an unreliable supplier, and a reliable supplier. The retailer faces shelf-life freshness-sensitive stochastic demand, the unreliable supplier exhibits random yield characteristics, and circulation loss of fresh produce are borne by the suppliers. First, we examine the retailer’s optimal ordering and freshness-keeping decisions as well as derive conditions for the existence of joint decision-making. Then, we analyze the optimal responsive pricing decisions of the two suppliers and identify wholesale price thresholds for maximizing market share for both the suppliers. Key findings include: (1) Increasing the retailer’s freshness-keeping effort level reduces the expected received quantity; (2) A wholesale price increase by either supplier decreases the retailer’s order quantity from that supplier while increasing orders from the other; (3) Product survival rate affects only the retailer’s ordering decisions, not its freshness-keeping effort level or expected profit; (4) A decline in product survival rate raises the unreliable supplier’s profit but lowers the reliable supplier’s profit. Finally, the extension model, which explores the scenario where the retailer exclusively sources from one supplier, reveals that cost serves as the determining factor in the retailer's selection. |
