集群式供应链中的物流价值链优化

集群式供应链源于产业集群和价值链理论.集群式供应链是一个复杂的物流价值链体系.从价值链角度进行集群式供应链优化,利用价值分析工具对集群企业问供应链物流活动(采购物流、生产物流、销售物流、逆向物流)进行价值量化,建立目标为最优成本投入比例的模糊线性规划模型,可确立供应链上各个物流活动的价值贡献,进而重建一条更为优化的物流价值链,以实现物流价值的增值(即物流成本的降低),提升集群企业供应链物流一体化的竞争优势.

转移价格的供应链激励机制与道德风险问题研究

考虑一个由制造商与分销商组成的供应链,制造商通过广告投入拉动产品销售,分销商通过促销活动推动产品销售。如果用一个制造商和两个分销商构成的供应链模型,来研究供应链中的博弈关系、激励机制和道德风险问题。只有给出两分销商的Nash均衡结果以及制造商与两分销商间的Nash均衡结果,才能解决供应链中的激励机制的设计。然后通过支付函数的全微分,来揭示供应链中的道德风险问题,从而证明供应链内部存在囚徒困境现象。

价格和服务竞争下多供应链间Bertrand博弈决策分析

假设顾客需求受价格和服务水平影响,以两条包含一个制造商和一个零售商的单链式供应链为研究对象,在Bertrand博弈框架下,讨论了两条供应链采用三种不同决策结构(分散——分散、分散——集中、集中——集中)时链间竞争情况。研究表明,链间价格和服务水平的竞争强度等关键变量对链间博弈均衡解有着重要的影响,特别地,当供应链间价格和服务竞争强度较低时,都采用集中决策是供应链间博弈的帕累托均衡解,但当竞争强度较高时,都采用集中决策会使两条供应链陷入"囚徒困境"。

Equilibrium in supply chain network with competition and service level between channels considering consumers' channel preferences

This paper considers a dual-channel supply chain network consisting of multiple competing manufacturers, multiple competing retailers and multiple demand markets. Each manufacturer produces and distributes his products via direct e-commerce channel along with traditional physical channel. The manufacturers also provide services for the consumers in both channels, while the retailers only offer offline services to the consumers. On this basis, a dual-channel supply chain network equilibrium model with pricing and service decisions are established based on variational inequality theory. Nash equilibrium solutions are obtained by modified projection and contraction method. Combined with numerical examples, we analyze the impact of three critical factors on the equilibrium states and profits. Some interesting managerial insights are derived. We find that the profits of the manufacturers decrease (increase) in the raw material conversion ratio under single channel case (dual-channel case), while the increase of the raw material conversion ratio always benefits the retailers and the whole dual-channel supply chain network; the service level in each channel is positively correlated with its transaction volume. There are significant inconsistencies among the best combinations of cross-channel price coefficients between two channels for the manufacturers, the retailers and the whole dual-channel supply chain network. The same equilibrium decision (service level, price) or profit may exhibit the opposite changing trend with respect to cross-channel price coefficients under two cases of active e-commerce transaction and inactive e-commerce transaction. When the introduction of e-commerce channel can bring more profits for the whole dual-channel supply chain network, the manufacturers should provide reasonable allocation schemes of profit increment for the retailers to satisfy their participation constraints.     

SUPPLY CHAIN CAPITAL: THE IMPACT OF STRUCTURAL AND RELATIONAL LINKAGES ON FIRM EXECUTION AND INNOVATION

Firms invest millions of dollars annually in developing their supply chains, with the broad goal of increasing their own performance. However, despite the significant resources deployed for supply chain development, the extent to which initiating, maintaining, and managing supply chain relationships contributes to firm success remains unclear. The current article provides conceptual development supporting the valuation of firm‐to‐firm supply chain connections from the perspective of the focal firm. Based on the social network and economics literatures, the article introduces the concept of supply chain capital, which comprises the value of both the structural configuration and relationship content of the firm's supply chain network. Following theoretical development, a non‐exhaustive set of propositions are constructed illustrating multiple ways that supply chain capital can be accrued and exploited for firm‐level benefit. Managerial recommendations for investment in supply chain capital are included, as are future directions for research in the area of supply chain networks.

Supply Chain Networks With Multiple Retailers: A Test of the Emerging Theory on Inventories,Stockouts, and Bullwhips

While various approaches to mitigating the bullwhip effect have been proposed, the composition of the underlying supply chain is often taken for granted. This article develops a set of simulation models to investigate changes to the supply chain itself and their impact on the bullwhip effect, on‐hand inventory, and stockouts. It is shown that particular supply chain networks have an impact on the bullwhip effect. Furthermore, the impact of supply chain networks on the bullwhip effect is moderated by the demand forecasting technique used. Finally, supply chain networks, forecasting techniques, and their interactions are found to influence on‐hand inventory levels and stockout rates for firms within the supply chain. Results also suggest that no one particular type of supply chain network dominates in terms of dampening the bullwhip effect, lowering on‐hand inventory levels, or reducing stockout rates. The optimal network depends on the forecasting technique used and other supply chain factors.     

供应链金融中网络连接对中小企业融资质量的影响研究

基于价值网的供应链信息资源价值研究

本文认为,随着社会经济的不断发展,企业之间的竞争已经转向了供应链之间的竞争,而信息资源产生的价值是供应链上最大的竞争资源,它能够支持业务流程创新、减少供应链中需求的变动性、更好地进行市场预测、协调企业内部供应链各环节关系、创造新的客户价值、缩短提前期,对供应链参与者具有非常重要的作用。文章提出,基于传统价值链的信息资源价值实现模式以供应链核心企业为中心,会导致对物流需求信息等物流信息资源的"牛鞭效应",降低物流信息资源的价值;而基于价值网的信息资源价值实现模式以最终客户为中心,可加快供应链响应速度,提高供应链竞争力,保障客户利益的实现,进而实现信息资源价值最大化,它产生的信息资源价值更大,更有利于供应链各参与者,是更为可取的模式。     

Supply Chain Specific? Understanding the Patchy Success of Ethical Sourcing Initiatives

As a number of high profile companies have found to their cost, corporate reputations can be significantly affected by firms' management of sustainability issue, including those that are outside their direct control, such as the environmental and social impacts of their supply networks. This paper begins by examining the relationship between corporate social responsibility, reputation, and supply network conditions. It then looks at the effectiveness of one tool for managing supply network sustainability issues, ethical sourcing codes of conduct, by examining how the characteristics of three supply networks branded clothes, DIY wood products and branded confectionary affects the implementation ethical sourcing codes of conduct. It ends by setting out conclusions on why implementation of such codes has been so much more successful in some sectors than others and recommendations on effective approaches to managing sustainability issues in supply networks.

Manufacturer encroachment with competing dual-purpose online retail platforms

This study investigates the manufacturer encroachment strategy within a supply chain composed of a manufacturer and multiple competing dual-purpose online retail platforms who value profit and consumer surplus. We examine the strategic interactions among manufacturer encroachment, platform dual-purpose concern, and retail competition. Some interesting results are obtained. First, with a single platform, the manufacturer's encroachment incentive exhibits a non-monotonic relationship with respect to the platforms' concern of consumer surplus. However, with multiple competing platforms, the increased concern of consumer surplus and retail competition intensity dampen the manufacturer's encroachment incentive. Second, manufacturer encroachment benefits platforms (supply chain) only when the platform's concern of consumer surplus is low and commission fee is moderate (low enough). Moreover, the increased retail competition intensity and the platform's concern of consumer surplus further aggravate the detrimental effect of manufacturer encroachment on the platforms and supply chain. Third, the dual-purpose concern of the platforms may hurt consumer surplus, whereas the increased retail competition intensity may contrarily alleviate this adverse effect to some extent. Finally, the profits for the platform and supply chain and consumer surplus are non-monotonic with respect to the platform's concern of consumer surplus.
