题目 供应不确定情况下制造商垂直信息共享与多源采购策略研究
主题词 供应不确定,成本减少努力,多源采购,需求信息共享,成本信息共享
摘要 经济全球一体化的日益加深使得供应链的网络更加复杂和供应链不确定性加剧。供应链的不确定性主要来源于供应不确定、需求不确定和成本不确定,这些不确定性给供应链管理带来了巨大的挑战。多源采购作为应对供应不确定的有效手段被广泛运用于工业实践。供应链中上下游成员之间共享需求和成本信息能够有效地应对需求和成本不确定。考虑由n个供应商和两个制造商构成的供应链,制造商拥有需求和成本信息,供应商可以决策是否采取生产成本减少努力来响应制造商的需求和成本信息。基于这样的供应链运营背景,分别在供应商不采取生产成本减少努力和采取生产成本减少努力情况下联合研究制造商的垂直需求信息共享策略、垂直成本信息共享策略及多源采购策略。通过建立多阶段博弈模型,结合解析和仿真分析,获得了制造商相应的垂直信息共享与多源采购策略管理启示。 在供应商不采取生产成本减少努力情形下制造商的垂直需求信息共享和多源采购策略方面,制造商与供应商共享需求预测信息使供应商的利润增加,制造商的利润减少。因此,制造商不会免费地向供应商披露其需求预测信息。在单边支付合同下,存在完全需求信息共享和没有需求信息共享两个对称的均衡策略。当需求预测误差充分小时,完全需求信息共享是近似帕累托最优的。研究供应相关性对多源采购策略的影响发现,当供应商数量多时,制造商总是选择相关性低的供应商进行多源采购。当供应商数量少时,制造商选择相关性低或相关性高的供应商进行多源采购依赖于供应不确定程度、需求预测误差以及制造商的垂直信息共享策略。在一定条件下,供应相关性越低,供应链中各成员以及整个供应链的期望利润越高。 在供应商采取生产成本减少努力情形下制造商的垂直需求信息共享和多源采购策略方面,当努力成本系数充分小时,制造商愿意免费地与供应商共享需求信息且存在不对称的垂直需求信息共享均衡。当努力成本系数较大时,供应商向制造商提供单边支付费用,在一定条件下可以使得两个制造商均与供应商共享需求信息。基于完全需求信息共享和没有需求信息共享两种情形下研究制造商的多源采购策略发现,制造商选择相关性高或相关性低的供应商进行多源采购依赖努力成本系数、供应商数量、供应不确定程度、需求预测误差以及制造商的垂直需求信息共享策略。此外,在一定条件下,供应商、制造商以及整个供应链的利润关于供应相关性系数递减。 在供应商不采取生产成本减少努力情形下制造商的垂直成本信息共享和多源采购策略方面,两个制造商均愿意免费地与供应商共享成本信息。完全成本信息共享会使得供应链中成员以及整个供应链的利润增大。关于多源采购策略,制造商选择相关性高或相关性低的供应商进行多源采购取决于供应商的数量、供应不确定程度、成本相关性系数和制造商的垂直成本信息共享策略。在一定条件下,供应商的期望利润关于供应相关性系数递减,而整个供应链的期望利润关于供应相关性系数递增。 在供应商采取生产成本减少努力情形下制造商的垂直成本信息共享和多源采购策略方面,在一定条件下,制造商、供应商和供应链受益于完全成本信息共享。基于完全成本信息共享和没有成本信息共享研究制造商的多源采购策略发现,制造商选择相关性高或相关性低的供应商进行多源采购,取决于努力成本系数、供应不确定程度、成本相关性系数以及制造商的垂直成本信息共享策略。另外,在一定条件下,供应商之间拥有低的供应相关性有利于供应商和制造商。 总之,当存在需求不确定时,供应商采取生产成本减少努力来响应制造商的需求预测信息时,在一定条件下也会使得制造商免费地与供应商共享需求信息。当存在制造商成本信息不确定时,供应商采取生产成本减少努力反而会抑制制造商与供应商共享成本信息。通过解析和数值分析发现,无论需求信息还是成本信息不确定,供应商采取生产成本减少努力对制造商的多源采购策略影响很小。
英文题目 THE MANUFACTURERS’ VERTICAL INFORMATION SHARING AND MULTI-SOURCING UNDER SUPPLY UNCERTAINTIES
英文主题词 Supply Uncertainty, Cost Reduction Effort, Multi-sourcing, Demand Information Sharing, Cost Information Sharing
英文摘要 The increasing global economic integration has complicated supply chain network and intensified the supply chain uncertainties. The uncertainties in supply chain management mainly arise from supply uncertainty, demand uncertainty and cost uncertainty. These uncertainties post great challenges to supply chain managers. Multi-sourcing, which is an effective operational strategy in mitigating supply uncertainty, is widely used in industrial operation. To cope with demand and cost uncertainty, many upstream and downstream supply chain members have teamed up to share demand and cost information. The supply chain with n suppliers and two manufacturers is considered. The manufacturers own demand and cost information. Moreover, the suppliers can make a decision on whether to take production cost reduction effort to response to the manufacturers’ demand and cost information. In such a supply chain, the manufacturers’ strategies of vertical demand information sharing, vertical cost information sharing and multi-sourcing are jointed investigated in the settings with and without the suppliers’ production cost reduction effort, respectively. A multi-stage game model is built to solve these problems. Managerial insights about vertical demand information sharing, vertical cost information sharing and multi-sourcing are obtained based on analytical and simulation analysis. The manufacturers’ vertical demand information sharing and multi-sourcing in the setting without the suppliers’ production cost reduction effort are jointly examined. It is found that the manufacturers sharing demand forecast information with suppliers increases the suppliers’ ex-ante payoffs, decreases the manufacturers’ ex-ante payoffs. Thus, the manufacturers have no willingness to disclose demand forecast information to suppliers for free. However, under a side-payment contract, there are two symmetric equilibriums: complete demand information sharing and no demand information sharing. Complete demand information sharing approximates to Pareto-optimal when manufacturers’ forecast error is less enough. The impact of supplier correlation on multi-sourcing is investigated. It is found that if the number of suppliers is large, the manufacturers could choose lowly correlated suppliers to make multi-source. If the number of suppliers is small, whether the manufacturers choose highly correlated or lowly correlated suppliers is dependent on the degree of supply uncertainty, forecast error and the manufacturers’ vertical demand information sharing strategies. Under certain conditions, the lower the supplier correlation is, the higher all supply chain member and total supply chain’s payoffs are. The manufacturers’ vertical demand information sharing and multi-sourcing in the setting with the suppliers’ production cost reduction effort are jointly examined. It is found that the manufacturers are willing to share demand information with suppliers for free only when effort cost coefficient is small enough. In addition, the asymmetry vertical demand information sharing strategy exists. When effort cost coefficient is large, under certain conditions, the suppliers can successfully induce both manufacturers to share demand information with them by playing a side-payment to manufacturers. Multi-sourcing is investigated based on the assumption of complete demand information sharing or no demand information sharing. It is found that whether the manufacturers choose highly correlated or lowly correlated suppliers to multi-source depends on effort cost coefficient, the number of suppliers, the degree of supply uncertainty, forecast error and the manufacturers’ vertical demand information sharing strategies. Moreover, the suppliers, the manufacturers and the total supply chain’s ex-ante payoffs decrease with supplier correlation under certain conditions. The manufacturers’ vertical cost information sharing and multi-sourcing in the setting without the suppliers’ production cost reduction effort are jointly examined. It is found that both manufacturers are willing to share cost information with suppliers for free. Complete cost information sharing increases supply chain members and the total supply chain’s ex-ante payoffs. In multi-sourcing, whether the manufacturers choose highly correlated or low correlated suppliers to make multi-source is dependent on the number of suppliers, the degree of supply uncertainty, cost correlated coefficient and the manufacturers’ vertical cost information sharing strategies. The suppliers’ payoffs decrease with supplier correlation, while the total supply chain’s payoff decreases with supplier correlation under some conditions. The manufacturers’ vertical cost information sharing and multi-sourcing in the setting with the suppliers’ production cost reduction effort are jointly examined. It is found that the suppliers, the manufacturers and the total supply chain benefit from complete cost information sharing under certain conditions. Multi-sourcing is investigated based on the assumption of complete cost information sharing or no cost information sharing. It is found that whether the manufacturers choose highly correlated or lowly correlated suppliers to multi-source is dependent on suppliers number, effort cost coefficient, the degree of supply uncertainty, cost correlated coefficient, and the manufacturers’ vertical cost information sharing strategies. Moreover, under some conditions, the suppliers with low supplier correlation benefit to both the suppliers and the manufacturers. In general, facing uncertain demand, the suppliers who make production cost reduction effort to response to the manufacturers’ demand information can successfully induce the manufacturers to share demand information with them for free under certain condition. Facing cost uncertainty, the suppliers who make production cost reduction effort to response to the manufacturers’ cost information will damage the manufacturers’ sharing cost information with them. The analytical and simulation analysis reveals that the suppliers’ production cost reduction behavior imposes little influence on the manufacturers’ multi-sourcing regardless of demand or cost uncertainty.
