已有的考虑两生产模式和期末二次订购的Newsvendor型产品供应链协调模型存在2个主要问题:①在集中决策下,供应链系统整体的期望利润表达式有误,并非为制造商和销售商在分散决策下各自期望利润的简单之和;②文献所提供的协调策略并不能使得供应链系统期望利润达到最大化。在修正已有文献中相关错误的前提下,重新建立了带有两生产模式的Newsvendor型产品供应链协调模型,提出了一个改进的收益共享契约来实现供应链的完美协调。最后,通过数值算例验证模型的优越性。
There are two problems in the existing supply chain coordination models for newsvendor-type products considering two production modes and end-of-season second order.First,the expected profit of the supply in the centralized decision-making system,which is defined as the sum of expected profits of the manufacturer and buyer in decentralized decision-making system by existing related literature,is incorrect correct.Second,the coordination policy provided by existing related literature cannot make the system's expected profit achieve the maximum.In this paper,we first re-establish the supply chain coordination model for newsvendor-type product with two production modes on the premise of correcting the mistakes of the existing related paper.Since the traditional coordination policies fail to realize the coordination,we then propose an improved revenue-sharing contract that can achieve perfect coordination of supply chain.Finally,numerical examples are provided to show the superiority of our model.
