考虑市场细分的零售商自主以旧换新策略研究

在越来越多企业开始自主推行以旧换新业务的背景下,本文从供应链的视角出发,构建考虑市场细分和消费者效用的策略模型,研究零售商自主以旧换新策略选择及相应的供应链决策问题,着重分析市场细分和旧产品折旧程度对策略选择、决策和供应链效率的影响.研究发现:零售商的策略选择除了受产品制造成本影响外,还依赖于外部客户比例和旧产品折旧程度;当老客户占比和旧产品折旧度处于某区域时,自主以旧换新策略优于无以旧换新策略;在某些情况下,制造商的期望策略与零售商的最优策略相悖;供应链效率受客户比例和旧产品折旧度影响.此外,当老客户占比或旧产品折旧度高于某阈值时,老客户对主体的利润贡献大于新客户.本文的研究结论对企业在供应链环境下推行以旧换新政策有一定的理论指导意义.     

Turbulent markets need flexible supply chain communication

This paper consists of three main sections. The first section discusses market turbulence and the transition from mass production to mass customization as driving forces for organizational change and optimization, which leads to IT-support and virtual enterprises. The second section describes the key-elements of supply chain management as one building block for virtual enterprises. Low-cost and flexible Electronic Data Interchange (EDI) is the key-enabler to automate the interactions between companies and their partners. In the third section, a complete concept and a prototype realization for Internet EDI-using XML (eXtensible Markup Language) is proposed. This approach is based on Internet and XML, because the implementation of traditional EDI (e.g. EDIFACT, ANSI X.12) is mostly too costly for small and medium sized enterprises, which has to be integrated as suppliers and customers in a supply chain. XML will be the international standard for Internet communication in the near future.     

UPSTREAM VOLATILITY IN THE SUPPLY CHAIN: THE MACHINE TOOL INDUSTRY AS A CASE STUDY

Cyclicality is a well‐known and accepted fact of life in market‐driven economies. Less well known or understood, however, is the phenomenon of amplification as one looks “upstream” in the industrial supply chain. We examine the amplification phenomenon and its implications through the lens of one upstream industry that is notorious for the intensity of the business cycles it faces: the machine tool industry. Amplification of demand volatility in capital equipment supply chains, e. g., machine tools, is particularly large relative to that seen in distribution and component parts supply chains. We present a system dynamics simulation model to capture demand volatility amplification in capital supply chains. We explore the lead‐time, inventory, production, productivity, and staffing implications of these dynamic forces. Several results stand out. First, volatility hurts productivity and lowers average worker experience. Second, even though machine tool builders can do little to reduce the volatility in their order streams through choice of forecast rule, a smoother forecasting policy will lead companies to retain more of their skilled work force. This retention of skilled employees is often cited as one of the advantages that European and Japanese companies have had relative to their U. S. competitors. Our results suggest some insights for supply chain design and management: downstream customers can do a great deal to reduce the volatility for upstream suppliers through their choice of order forecast rule. In particular, companies that use smoother forecasting policies tend to impose less of their own volatility upon their supply base and may consequently enjoy system‐wide cost reduction.     

Japanese Supply Chain Relationships in Recession

The remarkable nature of Japan’s supply chain relationships has been identified as a significant factor in its industrial success, especially in the automotive and electronics sectors. Yet, Japanese companies do not recognise the term ‘supply chain management’. For four decades Japan’s industrial giants developed sourcing strategies based on highly-pressured, customer-dominated supply relationships in which sub-contractors enjoyed the benefits of the success of their customers at the expense of yielding their autonomy. In 1991, the Japanese economy plunged into deep recession and has yet to recover. Large corporations now appear vulnerable and almost all Japan’s banks are technically insolvent. This article explains the ways in which recession has affected the supply chain relationships in Japan and the domestic and international sourcing strategies that shape them. Japanese industrial customers are now putting increased pressure on their suppliers to provide technical solutions and to develop links with other customers for the first time. The sub-structures of the keiretsu appear to be giving way to open competition with ‘parent’ firms selling equity in subsidiaries. Profound changes appear to be underway in Japanese industrial sourcing strategies—suppliers can no longer rely on retaining business simply by obedience and hard work. Instead, they face an open, fiercely competitive environment—at home and abroad. In this new order, Japanese suppliers are developing new competitive technical and commercial capabilities, enabling their Japanese industrial customers to concentrate on real-time, market-driven configuration of products, without needing to hold stocks in their supply chains and distribution channels. Meanwhile, Japan is seeking to re-establish its position of leading player in East Asia.     

An interdependent layered network model for a resilient supply chain

This paper addresses the problem of designing supply chains that are resilient to natural or human-induced extreme events. It focuses on the development of efficient restoration strategies that aid the supply chain in recovering from a disruption, thereby limiting the impact on its customers. The proposed restoration model takes into account possible disruptions to infrastructures, e.g., transportation and communications, by explicitly formulating their logical relationships with supply chains. A problem solving process is proposed that provides for cooperation between the managers of the infrastructures and the managers of the supply chains disrupted by an extreme event. Both the model and the problem solving process are exercised with a realistic industry problem.     

供应链治理机制与供应链绩效之间的相互作用关系——基于信息共享的中介效应和信息技术水平的调节效应

本文构建起了供应链治理机制与供应链绩效之间的相互作用关系理论模型，并进而对信息共享在其中所起的中介效应及信息技术水平在其中所起着的调节效应进行剖析。以380份来自于供应链相关岗位的中高层管理人员及技术人员的问卷作为样本，利用结构方程模型对社会控制、正式控制、信息技术水平、信息共享及供应链绩效之间的相关关系进行实证研究。研究结果表明：（1）社会控制对信息共享及供应链绩效均产生正向影响，信息共享对供应链绩效也产生正向影响；而正式控制则对信息共享产生显著的负向作用关系，且其对供应链绩效的作用关系并不显著；（2）信息共享在社会控制和供应链绩效之间的作用关系中起着部分中介的作用，但其在正式控制-供应链绩效间的中介作用则并不显著；（3）信息技术水平对于社会控制-信息共享和正式控制-信息共享间的关系具有调节效应。     

Impact of competitive conditions on supplier evaluation: a construction supply chain case study

This research proposes a multi-criteria decision-making (MCDM) framework and demonstrates the impact of competitive conditions on supplier evaluation process for construction supply chains. The paper focuses on the supply chain of a large-scale housing project in order to illustrate the role of competitive capability and suppliers’ profile and its influence on supplier evaluation based on prevailing supply/market conditions. Various scenarios are investigated to demonstrate the impact of competition on supplier evaluation. The contribution of the study lies in highlighting the impact of supply/market conditions on MCDM decisions causing supplier evaluation ‘imbalance’ and MCDM usage. It is expected that the study will be useful for project management, construction, supply chain management, sourcing professionals. The findings of the study are generalisable to projects-based situations such as petroleum refinery and ship building where bill of materials typically consists of thousands of items and a large number of suppliers are involved.     

高峰对话 唐·舒尔茨：品牌传播的杠杆法则 低成本也能做出大品牌

品牌是企业成长最重要的驱动力之一,这已是企业界的共识。虽然中国产品早已与国际品牌同台竞技,但在全球排名前20的品牌中,仍然没有中国企业的身影;在中国排名前10的品牌中,基本是电信或银行等国有垄断型企业。多年来,中国产品一直是廉价和OEM的代名词。如何在全球建立中国制造的优秀品牌形象,使之摆脱低成本和廉价印象？如何打造中国自己的强势消费类产品品牌？     

Strategic and operational considerations for the Extended Enterprise: insights from the aerospace industry

The extended enterprise (EE) paradigm has been adopted in the civil aerospace industry to enhance collaboration and product innovation among supply chain partners. Nevertheless, key aspects of this collaborative form remain poorly understood. In particular, the interrelation of strategic and operational considerations has received little attention in the literature. Our study aimed to investigate this area, using two dyads as case studies, where three companies were involved in an EE form of collaboration. The primary case company was a leading manufacturer in the civil aerospace industry that employs EE principles on both upstream and downstream sides of its supply chain. The other two case companies were key suppliers embedded in the EE. This paper aimed to develop a more complete understanding of how sharing risks and rewards results in effective collaboration among EE partners with key strategic and operational results.     

Supply‐Chain Research Opportunities with the Poor as Suppliers or Distributors in Developing Countries

Many social enterprises and some companies have developed supply chains with the poor as suppliers or distributors to alleviate poverty and to create revenues for themselves. Such supply chains have created new research opportunities because they raise issues fundamentally different from those examined in the existing operations management literature. We report this phenomenon of supply chains with the poor as suppliers or distributors in developing countries and identify operations management (OM) research opportunities. We also provide some stylized models to serve as potential seeds for modeling‐based research in this area.     

An examination of the strategic and operational impact of global sourcing on UK small firms

This paper presents three in-depth case studies of UK small manufacturers from the electronics manufacturing industry with global supply chains. There is no overlap in products, suppliers or customers and over time, each has developed a distinct and different strategy for managing an extended supply chain. The outcomes and experiences though are not markedly different. The operational challenges they encounter around quality and delivery, as well as the strategic dimensions of information asymmetry and capability fit are discussed. The study identifies the financial risks the firms are exposed to, the constraints to innovation and the wider strategic implications for long-term business performance.     

Information sharing in supply chains

Supply chain is defined as a system of suppliers, manufacturers, distributors, retailers and customers where material, financial and information flows connect participants in both directions. Most supply chains are composed of independent agents with individual preferences. It is expected that no single agent has the power to optimise the supply chain. Supply chain management is now seen as a governing element in strategy and as an effective way of creating value for customers. The so-called bullwhip effect, describing growing variation upstream in a supply chain, is probably the most famous demonstration that decentralised decision making can lead to poor supply chain performance. Information asymmetry is one of the most powerful sources of the bullwhip effect. Information sharing of customer demand has an impact on the bullwhip effect. Information technology has lead to centralised information, shorter lead times and smaller batch sizes. The analysis of causes of the bullwhip effect has lead to suggestions for reducing the bullwhip effect in supply chains by strategic partnership. Supply chain partnership leads to increased information flows, reduced uncertainty, and a more profitable supply chain. The cooperation is based on contacts and formal agreements. Information exchange is very important issue for coordinating actions of units. New business practices and information technology make the coordination even closer. Information sharing and strategic partnerships of units can be modelled by different network structures.     

销售成本信息不对称下供应商风险规避的回购契约

在价格随机条件下,销售成本信息不对称且供应商规避风险时,本文探讨回购契约协调供应链的最优决策。在前提假设的基础上构建新的回购契约模型,求解并用算例进行仿真验证,考虑信息不对称与风险规避共同发生耦合作用后对供应链相关决策变量的影响。研究结果表明：在价格随机条件下,不管信息是否对称,只要供应商有风险规避意识,供应链相关决策变量均发生分岔突变;不管市场价格是否随机,也不管供应商是否风险规避,只要零售商隐瞒私人销售成本信息,就会给自己带来额外的收益,但会给供应商与整个供应链带来损害;供应链上的信息越不对称,在分岔突变区域,相关决策变量的振荡幅度越大。分岔突变现象是市场价格随机和供应商风险规避耦合作用后特有的现象;零售商能够利用信息不对称给自己带来额外的好处,但会损害供应商和供应链的利益;供应商防范零售商这种损人利己行为的最好对策,就是通过设计一种合作机制,以最低成本的方式来促使零售商将销售成本信息公开化;另外,供应商以平稳的心态(风险中性)应对外部风险,更有利于提高其自身决策的水平。     

Sustainable supply chain management in the fast fashion industry: An analysis of corporate reports

In recent decades, the fast fashion industry has been characterized by widespread operations across both developing and developed countries. Due to the economic, social and environmental problems in developing countries, companies increasingly focus on sustainability and try to ensure the same quality and standards in working and production conditions throughout their supply chains. Although the tension in the exchange of resources between developing and developed countries lies at the heart of current sustainability activities, what these companies are actually doing to manage their supply chain has not yet been explored in depth in the literature. Drawing on the theoretical framework of Seuring and Müller (2008), the current study attempts to fill this void by conceptually mapping the current situation of sustainable supply chain management (SSCM) in the fast fashion industry by analysing reports from 9 companies that use the same reporting guidelines. The results of the study reveal that these companies focus significantly on supplier compliance with their code of conduct, employing further monitoring and auditing activities to prevent production problems in developing countries, improve overall supply chain performance and set sustainability criteria for their suppliers.     

基于采购商投资的双源采购与供应商定价决策

随着供应链的全球化发展,供应链成员企业的合作越来越紧密。许多采购商通过直接对供应商投资提高供应的可靠性或降低采购成本。本文研究双供应商-单采购商的两级供应链中采购商投资、供应商定价以及采购商采购决策。在此供应链中,供应商和采购商之间存在先后决策的Stackelberg博弈,供应商之间存在同时决策的贝特兰德博弈。本文考虑异质供应商,即供应成本与稳定性存在差异,接受采购商投资后两者的改进效应也不同,建立了采购商投资、供应商定价、采购商采购三阶段博弈模型,基于凸优化理论和博弈分析方法对问题进行分析,并应用邻域搜索的自适应差分计划算法对问题进行求解。研究了供应链成员企业的最优均衡决策,分析供应成本、供应稳定性以及投资改进效应对最优均衡决策的影响。     

MASCOT: An agent-based architecture for dynamic supply chain creation and coordination in the internet economy

The emerging global internet economy will increasingly put a premium on the ability of companies to quickly and accurately evaluate new market opportunities, new product/ subcomponent designs, and other strategic business decisions (e.g. make-or-buy) in coordination with potential supply chain partners. It also requires that companies be able to effectively and efficiently coordinate activities, e.g. production and transportation across supply chains that are dynamically set up in response to constantly changing and increasingly customized market requirements. This paper provides an overview of MASCOT ('multi-agent supply chain cordination tool'), a reconfigurable, multi-level, agent-based planning and scheduling architecture aimed at supporting these functionalities. It reviews key innovative elements of the MASCOT architecture with a special emphasis on its support of realtime mixed-initiative 'what-if' functionalities, enabling endusers at different levels within the architecture to rapidly     

Improving innovation performance through environmental practices in the fashion industry: the moderating effect of internationalisation and the influence of collaboration

In recent years, the scientific literature on supply chain management has increasingly debated on environmental sustainability as well as collaboration, presenting these issues as an important source of innovation along the supply chain. By combining literature streams on environmental sustainability, supply chain collaboration and innovation at the supply chain level, this paper aims to analyse whether the adoption of environmental sustainability practices and collaboration along the supply chain implies better innovation performance, in terms of differentiation from the competitors for higher quality, product or process. The paper also investigates whether the internationalisation, in terms of both production and distribution activities, negatively moderates this relationship. The study focuses on the fashion industry, and a survey of major Italian fashion companies was conducted. The main results of the research clearly show the positive impact of these practices on innovation performance. The paper also proves the existence of a moderating effect exerted by internationalisation on the relationship between environmental sustainability and innovation performance.     

The Effects of Competitive Environment on Supply Chain Information Sharing and Performance: An Empirical Study in China

Information sharing in supply chains has become an important topic over the past decade. This study uses data from 617 Chinese manufacturing firms to investigate the relationships among competitive environments, supply chain information sharing (SCIS), and supply chain performance. The results of structural equation modeling analysis show that (i) international competition is positively related to all three types of SCIS whereas local competition is not significantly related to any of the three types, (ii) internal information sharing is positively related to external information sharing with suppliers and customers, and (iii) internal information sharing and information sharing with customers are positively related to superior supply chain performance, whereas supplier information sharing is not significantly related to performance. The findings enhance our understanding of the relationships among competitive environment, SCIS, and supply chain performance in Chinese manufacturing settings.     

Supply chain strategies for speciality foods: a Norwegian case study

Despite strong market interest in speciality foods, producers find market access and distribution challenging. This exploratory research includes a literature review and five case studies of supply chains relating to shellfish, cheese, meat, potato and miscellaneous speciality foods in the mid-Norway region. The study identifies key supply chain configuration parameters from the extant literature, and these are used to analyse the cases. The study makes three main contributions to the literature: an analytical framework for analysing the supply chain characteristics of speciality foods; important supply chain factors for accessing the conventional food supply chain; and five propositions for improving market access. We argue that the speciality foods supply chain should be configured according to these propositions to ensure responsiveness to customer needs and to strengthen market access.     

考虑随机市场需求的双渠道供应链风险补偿策略研究——从质量与价格竞争视角

在由两个供应商和单个零售商构成的二级双渠道供应链系统中，分析了随机市场需求以及供应商之间同时存在价格与质量竞争的情形下的双渠道供应链协调问题。在供应链集中决策、无风险补偿及有风险补偿三种情境下，构建了基于质量和价格的风险补偿模型并求得纳什均衡解。研究结果表明：存在可行的需求风险补偿策略使得供应链达到协调水平，并且需求风险补偿策略对零售商更加有利；在需求风险补偿策略下，需求风险补偿价格与其对应批发价格正相关，与其产品质量水平负相关；价格竞争程度对零售商订货量具有负向影响作用，对供应链总利润影响作用随着竞争程度增加而减弱，质量竞争程度对零售商订货量和供应商产品质量水平具有正向影响作用，对供应链总利润影响呈倒U型关系；需求风险补偿策略能够激励零售商的订货行为，强化价格竞争程度和质量竞争程度对供应商订货量和供应链总利润的影响；在供应链系统中双渠道营销模式下的供应链总利润要优于单渠道营销模式下的供应链总利润。本文结论不仅详细剖析了风险补偿策略对双渠道供应链协调的影响关系，也理清了价格与质量竞争对各方行为策略的影响机理。
