供应链脆弱性的影响因素及其管理原则

本文认为,供应链的复杂性带来了风险性和脆弱性,并威胁到供应链的持续性;影响供应链脆弱性的因素,一是当前供应链运行模式注重效率而非效力,二是供应链的全球化趋势,三是生产分销的集中化,四是外包生产日益盛行,五是供应商数量缩减,六是需求波动,七是供应链成员间透明性和控制措施的缺乏。文章提出,要解决供应链脆弱性问题需要采用变化管理的方法,即“3P”管理原则。     

中国企业供应链管理现状及主要问题

供应链管理作为一种新的管理思想,对传统经营理念提出了挑战。中国企业供应链管理的应用方和服务商以大型企业居多,不同行业解决问题的侧重点各异,而且成功实现供应链管理的企业,不分行业均有明显效果。文章认为,中国企业在进行供应链管理过程中存在不少问题,如相当多企业仍片面地以自建现代物流设施代替供应链管理;多数企业的供应链管理不完整,并未在整个价值链上显示出竞争优势;一些企业不善于在供应链优质服务和总成本最小之间找到平衡点等。

Postponement Strategies for Global Downstream Supply Chains: A Conceptual Framework

Postponement is a well-known organizational concept and usually relates to the deferment in time of manufacturing and/or logistics operations. In the current global competitive landscape, situations where postponement can be applied are rapidly increasing. Faced with the wide range of customs duties and free-trade agreements currently in place, companies need to (re)design their postponement strategies to customize their products appropriately, and to the proper degree, in each market. As the actual location where operations take place has a major impact on a company’s overall performance, the spatial perspective must also be taken into account when designing global postponement strategies, alongside the conventional temporal perspective. Heretofore, the academic literature does not offer any comprehensive framework on a global scale either for handling what is known as the postponement boundary problem, or for conceptualizing the related postponement strategies. Building on previous research, the aim of the present study was to investigate the postponement concept in a global environment with a downstream focus. The intended purpose is twofold: first, to review and expand previous studies on the subject and, second, to provide some guidelines for conceptualizing global postponement strategies. A structured literature review was first conducted, followed by the development of a framework that combines both the temporal and the spatial dimensions. Finally, the framework was applied to a group of 28 business cases taken from the literature, to act as a bridge between academic theories and practitioners’ current business operations.     

Generative Mechanisms of the Adoption of Logistics Innovation: The Case of On‐site Shops in Construction Supply Chains

Empirical studies of logistics innovations have focused on the innovation process, bypassing much the innovative artifact or solution design itself. Focusing on the artifact and solution design in a case study, we contribute to the emerging theory of logistics innovations through articulating the generative mechanisms of the adoption of logistics innovation, that is, the mechanisms through which the design of the solution enables its adoption. We study On‐site Shop, a rare example from the construction industry of a logistics innovation that has successfully migrated from a limited number of pilots to common practice. The case study is based on insights from participation in the design of the solution, and on 55 interviews conducted in a relationship triad consisting of three groups: (1) construction site users, (2) the solution designers, and (3) the suppliers. We propose that standard and efficient solution set‐up is the key enabler of logistics innovation's adoption at temporary construction sites. Communication and operating rules facilitate adoption in the triad, whereas internal and external integration further advance adoption by creating links between the innovative logistics solution and other activities. Finally, trilateral collaboration and congruent technological frames in the relationship triad sustain adoption over time.     

Trajectories for Driving the Diffusion of e-Negotiation Service Providers in Supply Chains: An Action Research Approach

ABSTRACT

The recent proliferation of online-based trade makes negotiations with service providers for global supply networks evermore challenging. The Internet is believed to be a viable means for enabling and facilitating these supply chain interactions. As such, commercial web-based services that support negotiation processes have emerged (i.e., e-negotiation services). Even though these services have promising benefits for supply chain participants, they have not been accepted by most business users. Current e-negotiation studies fail to capture the substantive reasons of this low acceptance as they typically ignore real-world aspects of commercial negotiations. As such, this study argues that an action research approach is a plausible means to study this issue, and to drive changes in the e-negotiations services market. Accordingly, a research plan is outlined with guidelines and recommendations for future action research projects.     

On the “Invisible Inventory Conundrum” in RFID‐Equipped Supply Chains: A Data Science Approach to Assessing Tag Performance

Recent trade reports suggest that RFID implementation continues to lag lofty projections. A primary concern is that, despite the high cost of implementing RFID systems, realized read‐rates fall short of expectations. This results in the invisible inventory conundrum whereby tagged merchandise may still not be accurately represented in inventory records. Drawing from data science to address this issue, we ask: How can directed data mining models be used to identify laboratory test performance criteria for RFID tags that operate reliably across the idiosyncratic facilities (i.e., unique DCs, warehouses, and stores) that comprise apparel retailers’ supply chains? We investigate this question by advancing a methodology that integrates laboratory test performance data, field tests of RFID tags fixed to apparel items and scanned under normal operating conditions, and the application of five directed data mining models to the integrated data set of laboratory and field test results. Our analyses of 45,416 observations show that two directed data mining models may identify—with near‐100% accuracy—laboratory test criteria that discriminate tags having 99% or greater read‐rates in the field. Accordingly, our study validates a generalizable methodology for identifying technical performance standards for tags that operate reliably within apparel retailers’ supply chains.     

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.     

A Multinational Comparison of Key Ethical Issues, Helps and Challenges in the Purchasing and Supply Management Profession: The Key Implciations for Business and the Professions

This paper presents the findings of a study of purchasing and supply management professionals in India conducted to identify the key ethical issues they face in carrying out their work related responsibilities as well as to determine the extent to which various factors appear to be helpful or to present challenges to their efforts to act ethically in the course of their work. The Indian findings are then compared to those for studies conducted among purchasing and supply management professionals in the United States, United Kingdom and Canada. Key findings for the four studies are summarized and implications for business and the professions are presented.
