【摘要】 本文研究了在单个能力有限的供应商和多个零售商组成的供应链中,运用数量柔性契约对供应链性能的影响。我们建立了计算机仿真模型,模拟了多种供应链环境和不同的零售商预测方法。仿真数据表明,运用数量柔性契约提高了供应商的服务水平,降低了供应商的费用。当预测方法比较准确时,数量柔性契约还能降低零售商和供应链的费用,实现帕累托改进。研究还表明数量柔性参数的变化对供应商和零售商有相反的影响,而且它在不同的需求模式和预测方法下有不同的表现。供应链的生产能力系数和需求噪声的大小对我们的结论基本没有影响。更多还原

【Abstract】 This paper evaluates the impacts of quantity ?exibility contracts on the perfor-mance of supply chains with one capacitated supplier and multiple retailers under de-mand uncertainty. Computer simulation models were used to simulate di?erent de-mand forecasting decisions by the retailers under a variety of scenarios. Analyses ofthe simulation output indicate that quantity ?exibility can improve the service level ofthe supplier, and reduce its total cost. Quantity ?exibility can also reduce the total costfor the retailers and lead to Pareto improvements when forecasting method is relativelyaccurate. It is also found that values of ?exibility parameters have opposite e?ectson the performance of the supplier and retailers, and the impacts could be in?uencedby demand patterns and selection of forecasting methods. Our findings are relativelyconsistent for the environments with di?erent capacity tightness and demand noise.更多还原
