供应链企业投资RFID技术的成本分摊研究

RFID作为“物联网”的核心技术,其应用已扩展至供应链领域,为供应链管理带来极大的便利。然而目前RFID技术的应用几乎都是上游投资、下游受益,这极大地损害了上游企业投资RFID技术的积极性。为了采用RFID技术有效地管理供应链,其成本的合理分摊是一个迫切需要解决的问题。本文针对适合不同行业的几种典型供应链契约--批发价格契约、收益共享契约、回购契约,分别建立了相应的RFID技术应用的成本分摊模型,通过严密的数学推导,得出了链上企业可承担的RFID技术成本阈值、成本分摊系数区间以及合理的收益分配方案,并获得了相应的管理启示。该研究为供应链企业投资RFID技术提供了科学的成本分摊依据。     

基于RFID技术的供应链投资决策及协调策略研究

本文以单制造商和单零售商组成的两级供应链为研究对象,基于链上成员是否投资RFID技术,考虑四种情景:供应链成员均不投资RFID,仅零售商投资RFID,仅生产商投资RFID及供应链成员共同投资RFID。采用Newsvendor模型建立四种情景时链上成员的收益模型,得出Stackelberg均衡解和供应链成员的最优期望收益,探讨了RFID技术投资对各情景时链上成员收益的影响,得到了供应链成员共同投资RFID时的协调策略。研究表明:当RFID标签成本和零售商库存不准确率在相应的阈值内,零售商或制造商单独投资RFID技术均能提升自身收益,同时对链上其他成员的收益存在"正外部性";此外,收益共享契约能够有效地协调链上成员共同投资RFID技术后的供应链,并且该协调思想丰富并拓展了供应链投资RFID技术的协调研究。     

Misplaced Inventory and Radio‐Frequency Identification (RFID) Technology: Information and Coordination

Misplaced inventory is a major operational problem in many supply chains. Radio‐frequency identification (RFID) technology has been publicized as a promising solution for the misplaced inventory. Adoption of this technology has a fixed cost and variable cost of implementation, which can cause incentive issues in the supply chain. In this paper, we consider a supply chain under misplacement of inventory subject to uncertain demand. We study both centralized and decentralized cases and identify the conditions to coordinate the supply chain under implementation of RFID. We show that the incentives of the parties for investing in the technology are not perfectly aligned in the existence of the fixed cost of investment. Based on the relative payments of the parties for the fixed cost of investment, the incentives to adopt RFID can be characterized into regions, where we observe only one party or two parties benefiting from the technology when the tag price falls in a region specified in the paper. We further establish the effects of changes in mean and variance of a uniform demand on the incentives for investing in RFID and find that the incentives of the firms may indeed decrease as demand becomes more variable.     

A model of the adoption of radio frequency identification technology: The case of logistics service firms

Globalization and advances in information technology represent both realities and opportunities for enterprises in the 21st century. This paper aims to broaden understanding of service innovation as a critical organizational capability through which the adoption of information technology influences firm performance. This study examines how the adoption of radio frequency identification (RFID) technology influences the operational performance of logistics service firms. We develop the RFID adoption model based on the interorganizational information systems (IOS) view of the firm that integrates the various strands of research into the framework. The study draws from the related information technology and interorganizational information systems literatures to explore organizational factors associated with the adoption of RFID. A model of the associations between information technology and interorganizational information systems use, social support, power structure, organizational readiness, procedural flexibility, and top management support is developed, and hypotheses are advanced about the relationships among these constructs. An empirical survey was conducted among 500 logistics service firms in Taiwan. A total of 131 valid observations were analyzed using the partial least squares technique. Results showed that RFID adoption has positive effects on business practices, which in turn improves operational performance. We address the value of certain interactive firm behaviors in RFID adoption and identify related constructs of RFID adoption in terms of their efficiency and value for logistics service firms. These results have implications for both education and practice.     

Electronic Data Interchange: Research Review and Future Directions*

For nearly two decades, electronic data interchange (EDI) has been widely viewed as a technology pivotal to supply chain management that has also provided benefits to firms on multiple levels. Despite a substantial body of literature, there are a number of conflicting and inconclusive research results in this field. In this study, we synthesize the diverse body of research in EDI by organizing the literature into an initial theoretical framework. Based on a meta‐analysis of results from the empirical literature, we seek to clarify conflicting results from the literature in order to develop a more unified theoretical framework of contextual variables associated with EDI adoption factors and outcomes. From a managerial standpoint, our literature‐based framework offers a set of guidelines for making successful EDI adoption and implementation decisions.     

RFID技术压缩提前期对供应链收益的影响与协调

RFID技术能够压缩供应链的提前期,提高零售商的服务水平,同时也会增加供应链的成本,如何协调采用RFID技术后供应链成员的收益是迫切需要解决的问题。本文针对单供应商和单零售商的两级供应链,考虑提前期变化对供应链及其成员收益的影响,在假定RFID单位标签成本为一定值的情况下,研究了采用RFID技术前后分散式供应链和集中式供应链的收益,并探讨了契约参数的变化对供应链协调的影响。结果表明,收益共享契约能有效地协调采用RFID技术后的供应链,实现供应链成员的共赢,但是采用RFID技术后,能够协调供应链的契约参数的区间缩小,零售商的最优订货量减少,供应商的批发价格上升。最后得出供应链采用RFID技术后提前期压缩量的阈值,通过数值分析对结论进行了验证,该研究为供应链企业采用RFID技术提供了相应的管理启示。     

Inventory Record Inaccuracy,Double Marginalization,and RFID Adoption

Most retailers suffer from substantial discrepancies between inventory quantities recorded in the system and stocks truly available to customers. Promising full inventory transparency, radio frequency identification (RFID) technology has often been suggested as a remedy to the problem. We consider inventory record inaccuracy in a supply chain model, where a Stackelberg manufacturer sets the wholesale price and a retailer determines how much to stock for sale to customers. We first analyze the impact of inventory record inaccuracy on optimal stocking decisions and profits. By contrasting optimal decisions in a decentralized supply chain with those in an integrated supply chain, we find that inventory record inaccuracy exacerbates the inefficiencies resulting from double marginalization in decentralized supply chains. Assuming RFID technology can eliminate the problem of inventory record inaccuracy, we determine the cost thresholds at which RFID adoption becomes profitable. We show that a decentralized supply chain benefits more from RFID technology, such that RFID adoption improves supply chain coordination.     

RFID for Better Supply‐Chain Management through Enhanced Information Visibility

Mostly fueled by mandates, adoption, and implementation of the RFID, technology in the retail industry is growing rapidly. At these early stages of adoption, one puzzling issue for retailers and suppliers is the compelling business case for RFID. In order to explore the potential business case for RFID, we conducted a case study using actual RFID data collected by a major retailer for the cases shipped by one of its major suppliers. We show the physical layout of the RFID readers on a partial supply‐chain covering product movement from distribution centers to retail stores. First, in the analysis phase, we identify several performance metrics that can be computed from the RFID readings. Next, using this RFID data, we compute the values of those performance metrics. These values represent mean time between movements at different locations. Then, we discuss how these measures can assist in improving logistical performance at a micro supply chain level of operations between a distribution center and a retail store. We present how such information can be valuable to both the retail store operator and the supplier. We also discuss the initial lessons learned from actual RFID data collected in the field, in terms of data quality issues.     

The Value to the Customer of RFID in Service Applications*

This article examines how customer value may be affected by deploying radio frequency identification (RFID) technologies within service environments. Business articles promote operational cost savings and improved inventory management as key benefits of deploying RFID. In response, service firms are using RFID to reengineer service transactions and customer touchpoints. Customers may view these RFID applications to offer both benefits and drawbacks. This article demonstrates that individuals will recognize far more value from RFID service applications than just cost savings and inventory availability. The article analyzes qualitative survey responses on the value gained from RFID to identify a broad list of value objectives—benefits and drawbacks—associated with RFID service applications. The article contributes to academic literature by providing salient value dimensions for return on investment models of service RFID applications and for future empirical analyses of means‐ends and value‐profit chain models. Managers can use the list of dimensions to develop rich business cases for evaluating the benefits and costs from enhancing service operations with RFID. The identified drawbacks also provide managers with a resource for understanding potential risks of RFID applications.     

The (non-)application of blockchain technology in the Greek shipping industry

The implementation of blockchain technology (BCT) is gaining traction in supply chain networks, revolutionising the operation of contemporary supply chains and reshaping the potential of business relationships. Empirical studies on blockchain adoption are scant because implementation across networks is in fairly early phase of development, yet evidence from empirical studies is highly desirable. This is one of the first studies of blockchain adoption in the Greek shipping industry, which has not so far been examined by the literature, in direct comparison to early adopters in other European countries such as Norway. The research examined eight Greek shipping companies using workshops with experienced supply chain personnel. Qualitative analysis identified the current position of these organisations in terms of blockchain adoption, by considering possible benefits and inhibitors to implementation. Despite benefits of automated processes and reduced paperwork as a result of smart contracts, findings show a reluctance to adopt BCT. That is, enterprise resource planning (ERP) transformations have left organisations fatigued and disinclined towards further systems development and resistant to subsequent change. Also, the exposure of shared information in the shipping nexus is considered to cause a threat to competitive survival.     

A review of RFID technology and its managerial applications in different industries

Radio frequency identification (RFID) is an emerging technology that is increasingly being used in supply chain management. RFID technology plays an important role in supporting logistics and supply chain processes because of their ability to identify, trace and track information throughout the supply chain. The technology can provide suppliers, manufacturers, distributors and retailers precise real time information about the products. This accurate knowledge of the inventory would result in lower labor cost, simplified business processes and improved supply chain efficiency. If properly used, it has the potential to cut ordering lead time and cost on inventory control, increase the accuracy of inventory information, help avoid stockouts and boost the number of inventory turns. In this paper, we provide an overview of the current state of RFID applications in different industries and its impact on business operations. We provide extensive literature survey and develop a framework for future research areas in this field.     

供应链企业投资RFID技术的博弈均衡研究

本文以两条竞争供应链（每条供应链均包含一个制造商和一个零售商）为研究对象,基于其是否投资无线射频识别（Radio Frequency Identification,RFID）技术,分别构建了两条供应链均不投资RFID（N情景）、供应链1投资RFID（S1情景）,供应链2投资RFID（S2情景）,及两条供应链均投资RFID（T情景）的收益模型,求解出相应的最优解并探讨供应链投资RFID的均衡策略。研究发现：相较于N情景,单条供应链投资RFID技术对其竞争供应链成员收益产生"负外部性"。当RFID成本较低时,供应链的均衡策略为T情景;当RFID成本较高时,错放率较低的供应链不采用RFID技术,其竞争供应链将采用RFID技术以提高自身的竞争力。     

Realizing Benefits from Enterprise Resource Planning: Does Strategic Focus Matter?

A key driver of the recent wave of enterprise resource planning (ERP) implementations was the assumption that the integration of business information would provide firms with a competitive advantage, yet concrete business benefits have been uneven across adopting firms. A possible explanation is that although the resource‐based view holds that competitive advantage is derived from inimitable resources, ERP software has become a commodity. Socio‐technical theory suggests that internal organizational resources based on a foundation of ERP technology may be the true drivers of ERP benefits. A firm's strategic configuration is posited to influence the portfolio of organizational competencies available to leverage the benefits of integrated business information, and a number of hypotheses are developed based on the notion that firms with different strategic objectives will realize different operational benefits from the adoption of ERP systems. Survey data from North American manufacturing firms that have implemented ERP systems demonstrate that ERP adopters seeking operational performance improvements are likely to realize these benefits. On the other hand, those seeking external market and supply chain performance improvements must first establish a foundation of internal operational performance improvements before customer satisfaction and supply chain benefits can be realized.     

Market Impact on IT Security Spending

Traditionally, IT security investment decisions are made in isolation. However, as firms that compete for customers in an industry are closely interlinked, a macro perspective is needed in analyzing these decisions. We utilize the notions of direct‐ and cross‐risk elasticity to describe the customer response to adverse IT security events in the firm and competitor, respectively, thus allowing us to analyze optimal security investment decisions. Examining both symmetric and asymmetric duopoly cases using a continuous‐time Markov chain (CTMC) model, we demonstrate that optimal IT security spending, expected firm profits and willingness of firms to cooperate on security improvements are highly dependent on the nature of customer response to adverse events. We also examine the investment problem when security attacks on different firms are correlated.     

Can information technology enable profitable diversification? An empirical examination

Investments in information technology (IT) are now a major part of corporate investment, and the management of IT is essential to performance. In general, IT is expected to have performance effects when it is judiciously used to complement existing corporate capabilities. In this research, we examine how IT can complement diversification strategy. Using hypotheses and measures suggested by information processing theory and the theory of corporate strategy, testable hypotheses are derived to examine how IT can complement diversification. Results suggest that spending on computer technology significantly complements a strategy of unrelated diversification. Implications for theory and practice are discussed.     

Simulation Modeling and Analysis: A Collateral Application and Exposition of RFID Technology

RFID technology provides in‐depth, real‐time visibility into the status of assets throughout the supply chain. However, the deployment of RFID technology may have collateral value in the high‐quality data generated by these assets. This study explores the potential value of RFID data for tactical and strategic purposes and the redesign of processes within supply chain through the deployment of simulation modeling and analysis. We present a simulation study conducted at a regional hospital for which data related to trauma patient movement was collected with an RFID‐based system. We find that not only does this data serve as the basis for successful simulation modeling, but that RFID technology may address several data‐related challenges previously identified in the simulation literature.     

Environmental Factors,Managerial Processes,and Information Technology Investment Strategies

Although significant research attention has been directed at understanding the value of information technology (IT) investments for firms, very little attention has been paid to understand the IT investment behavior of firms. This article seeks to fill this void. We introduce the concept of IT investment strategy, defined by dimensions of intensity and proactiveness, to characterize the IT investment behavior of firms. Synthesizing the environmental deterministic and strategic choice perspectives of a firm's strategic decision making, we examine the effects of environmental factors, managerial processes, and the interplay between them on IT investment strategy. Specifically, we examine the impact of environmental factors such as industry clockspeed and information intensity on IT investment strategy. We also incorporate the strategic choice perspective to argue that managerial processes such as frequent chief executive officer—chief information officer communications and collective information systems planning play a critical role in shaping the firm's IT investment strategy. The empirical results show that the environmental variables are related to IT investment strategy. Besides, managerial processes serve as a means to understand the environment and thus moderate the relationships between the environmental variables and the various facets of IT investment strategy. The conceptualization of IT investment strategy and the focus on both environmental determinism and strategic choice should enrich our understanding of firms’ IT investing behavior.     

Systems Collaboration and Strategic Collaboration: Their Impacts on Supply Chain Responsiveness and Market Performance*

Recognizing the importance of interfirm collaboration and recent advancement of information technology (IT) to enhance joint decision making between firms, this study conceptualizes systems collaboration and strategic collaboration as two essential types of interfirm collaboration. The study then simultaneously examines the multiple roles of systems collaboration and strategic collaboration, and how they directly and indirectly influence a firm's supply chain responsiveness and market performance. Hypotheses are tested on survey data collected from 184 firms. Results suggest that the sequential relationships among IT competency, interfirm collaboration, and supply chain responsiveness have significant market performance implications.     

Determinants of intranet diffusion and infusion

Commercial interest in Internet technology has grown tremendously in the last decade. Until now, little research has been devoted to examining the internal deployment of Internet technology. The present study focuses on the implementation process of intranets by examining factors associated with its diffusion and infusion in organizations. Findings suggest that earliness of adoption, top management support, and organizational size are positively associated with intranet diffusion. Intranet infusion is positively associated with earliness of adoption, top management support, and IT infrastructure flexibility, and these effects are mediated by intranet diffusion. Implications for management and suggestions for further research are discussed.
