摘　　要：为研究可控提前期对供应链最优决策的影响,基于交易信用契约,研究了由单个供应商与单个零售商组成的两级供应链库存协调问题。假设补货提前期可控,得到分散式、集中式和协调模型中供应商与零售商的最优策略组合。研究表明:基于交易信用和批发价格溢价的协调机制共同作用不但提高了整个供应链的绩效水平,而且实现了额外利润在供应商与零售商之间的合理分配;协调的批发价格随着零售商资金机会成本的增加而增加,随着供应商资金机会成本的增加而减少;交易信用契约的协调区间随着零售商资金机会成本的增加而增大,随着供应商资金机会成本的增加而减小。通过算例分析考察了需求标准差和单位缺货成本对供应链最优策略与系统利润的影响,结果表明,该模型不但提高了整个供应链的绩效水平,而且实现了额外利润在供应商与零售商之间的合理分配。To research the effect of controllable lead time on supply chain decision making, the inventory coordination issue of a supply chain composed of a supplier and a retailer was investigated. The optimal strategy composition of supplier and retailer in decentralized, centralized and coordinate model were obtained by assuming the lead time was controllable. The research showed that the overall chain profitability was improved based on the coordination mecha-nism acted by credit option and premium price, and the additional profit allocated between supplier and retailer ra-tionally was realized. The coordinated wholesale price and the length of coordination interval were increased with retailer’s capital opportunity cost and decreased with supplier’s capital opportunity cost. A numerical experiment was conducted to verify the proposed model and relevant results.
