This study considers a supply chain consisting of a commodity supplier and a final product manufacturer with uncertain demand. In addition to purchasing from the supplier through a forward contract, the manufacturer can adjust their inventory by trading the commodity in an online spot market after observing the actual demand. However, the spot market is imperfect in that transactions cannot be certainly realized and come with additional transaction costs. Furthermore, the spot price is volatile such that overly relying on the spot market is unwise. To investigate how the spot market affects the decisions and coordination in a supply chain, we develop a game-theoretical model incorporating spot trading. We derive the optimal ordering decision in a centralized supply chain, as well as the supplier's and manufacturer's equilibrium pricing and ordering decisions in a decentralized supply chain. The impact of the imperfect spot market on the optimal decisions and profits is analyzed. This study also demonstrates how the supply chain can be coordinated in the presence of an imperfect spot market. Finally, a numerical analysis is performed to examine the analytical results. Our results indicate that the spot market can generally improve the performance of the centralized supply chain and benefit the manufacturer in the decentralized one. However, it can be detrimental to the supplier. The supply chain can be coordinated by a revenue-sharing contract, and both parties' profits can be improved. Our findings suggest that the manufacturer could take advantage of the spot market, and the supplier should attempt to integrate or coordinate the supply chain to share the benefits of spot trading.  相似文献

In this paper, we define supply chain quality management (SCQM) to operationalize and understand the effect of increased emphasis on supply chain management on the practice of quality management. We review current research in quality management and identify common themes found in the literature. Key quality management content variables identified are customer focus, quality practices, supplier relations, leadership, HR practices, business results, and safety. We use these variables to propose areas for future research in the field of supply chain quality management.  相似文献

Supply chains are large, complex, and often unpredictable. Purchasing and supply managers and supply chain risk managers need methods and tools to enable them to quickly understand how unexpected disruptions in the supply chain start and grow and to what extent will they negatively impact the flow of goods and services. This paper introduces a methodological approach that can be used by both researchers and managers to quickly visualize a supply chain, map out the propagation path of disruptive events from the supply side to the end customer and understand potential weaknesses in the supply chain design; taking into account the structure, connectivity, and dependence within the supply chain. The approach incorporates a Petri net and Triangularization Clustering Algorithm to offer insights into a supply chain network's vulnerabilities and can be used to efficiently assess supply chain disruption mitigation strategies, especially in complex and difficulty to analyze supply chain systems.  相似文献

Family-owned enterprises dominate global business, generating 70–90% of the world's gross domestic product. Existing management research has validated that family businesses often behave differently than non-family businesses, primarily by focusing on idiosyncratic non-economic goals that are not typically assessed in traditional business research. Extant supply management literature has yet to investigate the influences of family business, thus overlooking a potential significant source of variation in our research as well as limiting our managerial relevance. The objective of this paper is to introduce supply management scholars to family business, including its prominence and unique characteristics. Applying socioemotional wealth as a theoretical lens, we develop a research agenda from existing supply management and family business literature by offering propositions for future research where family business influences may permeate contemporary supply management topics including strategic supply management, sourcing strategy, supplier relationships, sustainability, risk, and e-procurement. In doing so, we provide an initial foundation for supply management scholars to both incorporate family business effects into research and launch new research streams. This is one of the first papers to our knowledge that introduces the field of family business to supply management scholars.  相似文献

Supply chain practice and information sharing   总被引:9,自引:0,他引:9  
Effective supply chain practice and information sharing enhances the current supply chain management environment. The purpose of this study is to investigate the integration of information sharing and supply chain practice in supply chain management. Data from 125 North American manufacturing firms were collected. The results show that (1) effective information sharing significantly enhances effective supply chain practice; (2) supply chain dynamism has significant positive influence on effective information sharing as well as effective supply chain practice. Supply chain dynamism has more influence on information sharing than supply chain practice; (3) and effective supply chain practice becomes more important when the level of information sharing increases. The findings show that both effective information sharing and effective supply chain practice are critical in achieving good supply chain performance.  相似文献

Today’s marketplace is characterized by intense competitive pressures as well as high levels of turbulence and uncertainty. Organizations require agility in their supply chains to provide superior value as well as to manage disruption risks and ensure uninterrupted service to customers. Thus the cultivation of agility is approached as a risk management initiative that enables a firm to respond rapidly to marketplace changes, as well as anticipated and actual disruptions in the supply chain. Agility is of value for both risk mitigation and response.  相似文献

In most organizations, supply chain planning is a cross-functional effort. However, functional areas such as sales, marketing, finance, and operations traditionally specialize in portions of the planning activities, which results in conflicts over expectations, preferences, and priorities. We report findings from a detailed case analysis of a supply chain planning process that seemingly weathers these cross-functional conflicts. In contrast to traditional research on this area, which focuses on incentives, responsibilities, and structures, we adopt a process perspective and find that integration was achieved despite formal functional incentives that did not support it. By drawing a distinction between the incentive landscape and the planning process, we identify process as a mediator that can affect organizational outcomes. Thus, organizations may be capable of integration while functions retain different incentives and orientations to maintain focus on their stakeholders’ needs. Through iterative coding, we identify the attributes of the planning process that can drive planning performance—information, procedural, and alignment quality—but also find evidence that achieving alignment in the execution of plans can be more important than informational and procedural quality. In addition to process attributes, we also identify social elements that influenced the performance of the planning process and place the information processing attributes within a broader social and organizational context.  相似文献

Traditionally, distribution has been viewed as the key (physical) link between a company's internal supply chain activities and its customers. More recently, demand management has emerged as a new dimension at the customer interface. Although it has become increasing popular in industry, it has not yet been analyzed in depth with respect to its impact on supply chain performance. Both distribution management and demand management entail customer-facing processes and practices and that are interrelated and (may) jointly determine supply chain performance. In this paper we seek to extend the stream of research in supply chain management by systematically investigating the impact of customer-facing supply chain practices on supply chain performance. Specifically, the paper examines the relative impact of relevant practices associated with demand and distribution management. To this end, we collected data from 116 multi-national companies based in Europe and analyzed it using structural equation modeling techniques. Our results suggest that (i) high demand management performance has a substantial positive impact on the overall supply chain performance, (ii) this effect is stronger than that of distribution management performance, and (iii) there is no evidence that demand management might be an enabler for effective distribution management. Among the individual practices that constitute demand and distribution management, adherence to the demand and distribution management processes and demand segmentation emerged as the strongest performance levers. Based upon additional in-depth interviews conducted with selected companies from our sample, we shed light on some of the most important findings that emerged from our survey analysis.  相似文献

Building on knowledge management and innovation capability theories, this paper aims to reveal the mechanisms of collaborative innovation processes by investigating the complex relationships among critical factors influencing firm's innovation performance in supply chain networks. Using hierarchical Multiple Regression (MR) and Moderated Multiple Regression (MMR) methods, results from a survey of 236 firms in China indicated that there are significant positive relationships between collaborative innovation activities, knowledge sharing, collaborative innovation capability, and firm's innovation performance. Moreover, it is expected that knowledge sharing plays a partial mediating role in the relationships between collaborative innovation activities and firm's innovation performance. Collaborative innovation capability exhibited a moderating effect on collaborative innovation activities - innovation performance relationship. These results contribute to collaborative innovation process management by offering a nuanced conceptualization of the collaborative innovation - performance relationship in supply chain networks.  相似文献

Barriers to supply chain information integration: SMEs adrift of eLands   总被引:2,自引:1,他引:2  
The literature extols the potential benefits of supply chain integration and the crucial role of integrated eBusiness to deliver those benefits. However, adoption of eBusiness in supply chains has been slower than expected, particularly in small to medium sized enterprises (SMEs). This paper reports findings of a longitudinal study of four supply chains in different sectors over a 4-year period. Specifically it examines the barriers to adoption of eBusiness technologies and therefore to achievement of integrated information in supply chains. Differences between firms in supply chains and between supply chains are examined. The study reveals disparity between existing and planned use of eBusiness by larger downstream firms compared to upstream SMEs. The SMEs are cautious, only planning to invest in eBusiness if dominant downstream customers force them; however, they do not appreciate the full benefits to be gained from eBusiness adoption. The downstream larger businesses are forging ahead with eBusiness in ‘eIsolation’ and are not providing supply chain leadership. They are creating eLands with SMEs adrift of them.  相似文献

Forecasts can be used in an extraordinarily diverse range of ways across many domains in which forecasting practitioners work continuously towards improving their forecasts. Each of these domains may require the analysis of different kinds of inputs and special considerations. Even within a given domain, such as retail, there may be many similar use cases of the same kind of forecast, which can lead to practitioners making different decisions. This paper discusses several of the important decision points that practitioners must work through and uses item-level sales forecasting in the retail domain as leveraged by pricing and inventory management as examples of the different paths that may be taken. It considers how each use can lead to a different forecasting objective, and a corresponding focus on different error metrics. In addition, there are several tradeoffs in the forecasting methods that are used to meet each of the objectives best, including the kinds of models used, the running time speed, and forecast accuracy requirements.  相似文献

An empirical investigation into supply chain vulnerability   总被引:4,自引:0,他引:4  
A growing number of academicians and practitioners have put supply chain risks on their agendas, particularly triggered by a recent series of catastrophic events that have disrupted economies and supply chains around the globe. Given the increasing awareness of this important topic, the purpose of this research was to study supply chain risks in more detail and to investigate the relationship between supply chain vulnerability and supply chain risk. Responses from 760 executives from firms operating in Germany reveal that supply chain characteristics such as a firm's dependence on certain customers and suppliers, the degree of single sourcing, or reliance on global supply sources are relevant for a firm's exposure to supply chain risk. Overall, this research represents the first large-scale investigation of this important relationship and provides a finer understanding of the antecedents of supply chain vulnerability.  相似文献

This research examines the high level of change in supply organizations of large North American companies using data collected from 51 large North American supply organizations in 1987, 1995 and 2003. Analysis is supplemented by an additional 55 companies for which data were collected in 1995 and 2003. The availability of longitudinal data from individual companies over a 16-year period provided a unique opportunity to trace changes made to each company's supply organizational structure and their roles and responsibilities. Findings suggest that the respondents made major changes in supply organizational structure, supply chain responsibilities, use of purchasing teams, supply involvement in major corporate activities (MCA) and CPO reporting line, title and background.  相似文献

This study extends the developing body of literature on supply chain integration (SCI), which is the degree to which a manufacturer strategically collaborates with its supply chain partners and collaboratively manages intra- and inter-organizational processes, in order to achieve effective and efficient flows of products and services, information, money and decisions, to provide maximum value to the customer. The previous research is inconsistent in its findings about the relationship between SCI and performance. We attribute this inconsistency to incomplete definitions of SCI, in particular, the tendency to focus on customer and supplier integration only, excluding the important central link of internal integration. We study the relationship between three dimensions of SCI, operational and business performance, from both a contingency and a configuration perspective. In applying the contingency approach, hierarchical regression was used to determine the impact of individual SCI dimensions (customer, supplier and internal integration) and their interactions on performance. In the configuration approach, cluster analysis was used to develop patterns of SCI, which were analyzed in terms of SCI strength and balance. Analysis of variance was used to examine the relationship between SCI pattern and performance. The findings of both the contingency and configuration approach indicated that SCI was related to both operational and business performance. Furthermore, the results indicated that internal and customer integration were more strongly related to improving performance than supplier integration.  相似文献

The Belt and Road Initiative (BRI) is a massive, ambitious, long-term project initiated by the Chinese government, with participation from many other countries, to facilitate trade and improve logistics in an effort to promote global economic development. In this paper, we identified the supply chain and logistics innovations linked to the BRI. These innovations include new routes and modes for global trade, new supply chain design, reduction of cross-border logistics frictions, and entrepreneurial development. Examples of some of these innovations are emerging, while new ones are being developed. These innovations can enable businesses to improve their operational performances and create economic value. At the same time, to realize the full potentials of BRI, new work processes and technologies, incentive alignment, collaborations among businesses, and optimized planning are needed. This provides great opportunities for researchers to explore how to overcome barriers and achieve the full values of BRI.  相似文献
