在现代全球供应链系统战略中，防止供应链中断的风险管理的重要性正在增加。解决这个问题的一个有效方法是制造商和零售商之间的合作。将基于联合经济批量问题的确定性供应链模型推广到考虑价格敏感需求不确定性的随机规划模型。基于个体和合作模型的数值实验结果的比较表明，制造商-零售商的合作可能是有益的，在增加整个供应链系统的整体利润。例如，在本文所用的参数范围内，联合优化使总利润增加了0.11-12.92%，并且在需求对价格敏感的情况下，总利润的增长率要高得多。然而，上述合作可能会降低零售商的利润。基于此，本研究提出并建立一个在上述模型基础上加入利润约束的合作模型。结果表明，零售商的利润损失减小到0.0020- 0.0164%，即所提出的模型能够通过使制造商和零售商的利润损失尽可能小来使总利润最大化。
In modern global supply chain system strategies, the importance of risk management to prevent disruption thereto is increasing. One efficient approach for overcoming this problem is a collaboration between manufacturers and retailers. This study extends a deterministic supply chain model based on the joint economic lot-sizing problem (JELP) to a stochastic programming model, which considers the uncertainty of price sensitive demand. A comparison of the results from numerical experiments based on individual and cooperative models suggests that a manufacturer-retailer collaboration could be beneficial in increasing the overall profit of the entire supply chain system. For instance, total profits were increased by 0.11-12.92% under joint optimization in the range of parameters used in this paper and the growth ratio was considerably higher for the cases in which the demand was more price sensitive. However, the above collaboration can decrease the retailer’s profits. For this reason, this study proposes and formulates a collaborative model by adding profit constraints to the above model. As a result, the diminution of the retailer’s profits is decreased to 0.0020-0.0164%, that is, the proposed model is able to maximize the total profit by minimizing the reduction of the profits for both the manufacturer and the retailer as much as possible.
