【摘要】：信息共享是跨组织合作的基础,也是实现供应链协同的有效途径之一。跨组织信息共享可以有效地降低供应链的不确定性,抑制牛鞭效应,降低库存成本,提高服务水平等已成为学术界和供应链管理实践不争的事实。但企业实际运作中,信息共享战略的效果却往往不尽人意,付出了昂贵的成本与合作伙伴建立了跨组织信息系统(IOS)后,不仅没能实现信息共享的价值,反而导致企业利益,甚至供应链整体价值的损失。可见,信息共享并不是在任何情况下都有效,其对供应链的价值需要具体问题具体分析。因此,全面了解影响供应链信息共享有效性的因素,研究信息共享战略失效的内在原因不仅有理论价值,而且有重要的实践意义。导致信息共享失效的原因是多方面的,本文总结了影响供应链信息共享有效性的因素,并在此基础上提出了两个假设：(1)实现信息共享后,如果供应链各节点企业的决策在时间上不一致,则会导致信息共享的失效。一般情况下,决策在时间上的不一致体现在决策时滞上；(2)实现信息共享后,如果各节点企业对同一共享信息的理解出现偏误,则同样会导致信息共享的失效。为了验证这两个假设,本文分别构建了包含一个供应商与n个零售商的一对n供应链,以及包含n个供应商与n个零售商的n对n供应链,在信息共享下的动态系统模型,并以牛鞭效应为主要评价指标,通过仿真实验,研究企业决策时滞和信息理解偏误对信息共享有效性的影响,试图从这两个角度解释供应链信息共享失效的内在原因。研究结果表明：在实现信息共享后,供应链各环节的决策时滞以及各节点企业对同一共享信息的理解偏误,均会对信息共享的有效性造成巨大的负面效应,导致信息共享的失效。除此之外,本文通过研究还发现,在一对n的供应链系统中,决策时滞对企业的影响会沿供应链向下游传播,并且在传播的过程中具有叠加性。相反,在n对n的复杂供应链网络中,决策时滞的传播效应和可叠加性并不存在。
[Abstract]:Information sharing is not only the foundation of cross-organization cooperation, but also one of the effective ways to realize supply chain cooperation. Cross-organization information sharing can effectively reduce the uncertainty of supply chain, restrain bullwhip effect and reduce inventory cost. Improving service level has become an indisputable fact in academic circles and supply chain management. However, the effect of information sharing strategy is often unsatisfactory in the actual operation of enterprises. After paying the expensive cost and establishing the inter-organizational information system IOSs, it not only failed to realize the value of information sharing, but also led to the loss of the benefit of the enterprise and even the value of the supply chain as a whole. Information sharing is not effective under all circumstances, and its value to supply chain needs specific analysis. Therefore, it is necessary to fully understand the factors that affect the effectiveness of information sharing in supply chain. The study of the internal causes of the failure of information sharing strategy has not only theoretical value, but also important practical significance. There are many reasons leading to the failure of information sharing. This paper summarizes the factors that affect the effectiveness of information sharing in supply chain, and puts forward two hypotheses: 1) after realizing information sharing, If the decision of each node enterprise in the supply chain is inconsistent in time, it will lead to the failure of information sharing. If each node enterprise misunderstands the same shared information, it will also lead to the failure of information sharing. In order to verify these two hypotheses, this paper constructs a pair of n supply chain including one supplier and n retailers, respectively. The dynamic system model of n-pair supply chain, which includes n suppliers and n retailers, under information sharing, and the bullwhip effect as the main evaluation index, are simulated. This paper studies the influence of enterprise decision delay and information understanding bias on the effectiveness of information sharing, and attempts to explain the internal causes of information sharing failure in supply chain from these two angles. The results show that: after realizing information sharing, The decision delay in each link of the supply chain and the misunderstandings of each node enterprise to the same shared information will cause a huge negative effect on the effectiveness of information sharing and lead to the failure of information sharing. In addition, this paper also finds that. In a pair of n-supply chain systems, the influence of decision delay on enterprises propagates downstream along the supply chain and has superposition in the process of transmission. The propagation effect and superposition of decision-making delay do not exist.
