Blockchain technology for enhancing supply chain resilience

With the soaring value of bitcoin and frenzy over cryptocurrency, the blockchain technology that sparked the bitcoin revolution has received heightened attention from both practitioners and academics. Blockchain technology often causes controversies surrounding its application potential and business ramifications. The blockchain is a peer-to-peer network of information technology that keeps records of digital asset transactions using distributed ledgers that are free from control by intermediaries such as banks and governments. Thus, it can mitigate risks associated with intermediaries’ interventions, including hacking, compromised privacy, vulnerability to political turmoil, costly compliance with government rules and regulation, instability of financial institutions, and contractual disputes. This article unlocks the mystique of blockchain technology and discusses ways to leverage blockchain technology to enhance supply chain resilience in times of increased risks and uncertainty.     

How does the retailing industry decide the best replenishment strategy by utilizing technological support through blockchain?

Practitioners face two significant issues: product inaccuracy and transparency in supply chain management. Blockchain is a highly secure and trustworthy means of storing data. Radio frequency identification incorporation is essential if reliability is at a low level. Incorporating radio frequency identification can improve supply chain management in terms of product's visibility for the best replenishment strategy. A production and replenishment coordination via mathematical modeling is visualized through a three-echelon supply chain with a non-reliable production process, and the retailer deals with misplacement issues. The manufacturer handles the inventory flowing reversely and is responsible for proper end-of-life treatment, either repairing or remanufacturing. Repairs are sold in bulk on the secondary market, and remanufactured items are used to prevent retailers' shortages. In this model, radio frequency identification technology on the physical surface is combined with a blockchain on the cyber surface, containing all the information about the product, including its location and attributes. A comparative study is provided for the traditional supply chain with misplacement versus a blockchain-based supply chain with radio frequency identification. An analytical approach is used to arrive at the optimum policy for the practitioners, and numerical analysis illustrates the problem. Numerical experiments indicate that the technology is highly profitable for supply chain management. Radio frequency identification technology can increase profit by up to 61%. After discrepancy, holding cost is the second most sensitive parameter for the profit function. If the holding cost is higher, profit can be increased by 40% using radio frequency identification and blockchain. The negative effect of misplacement is reduced with an increasing demand rate, but the reduction rate is very slow. The choice of not adopting radio frequency identification can only be successful if demand is so high that it can reduce the effect of misplacement.     

It’s real,trust me! Establishing supply chain provenance using blockchain

In a global marketplace, customers are often unaware of the exact sources of the products they purchase and consume. To address this lack of awareness, blockchain technology can be implemented in supply chains to increase customers’ knowledge of products’ provenance. Provenance knowledge—information about products’ origin, production, modifications, and custody—enables customers to be assured of their purchasing decisions. This assurance comes from information on the origin, authenticity, custody, and integrity of the product that helps reduce risk perceptions. We develop a provenance knowledge framework and show how its application can enhance assurances and reduce perceived risks via the application of blockchain. We present a guide on how to implement blockchain to establish provenance knowledge and close with a kind warning on the importance of demonstrating the value of blockchain to customers.     

A THREE‐STAGE IMPLEMENTATION MODEL FOR SUPPLY CHAIN COLLABORATION

Leading companies know that collaboration and creativity in supply chain (SC) relationships are critical to future competitiveness. Yet, many companies struggle to collaborate effectively. This reality raises the question: “How can managers overcome the cultural and structural impediments to SC collaboration?” Through a series of in-depth, semi-structured interviews, we identify core practices and key requirements to successful SC collaboration. Contingency and force field theories help transform our field study findings into a three-stage model for improving SC collaboration. The constant challenge of persuading other managers and companies to pursue SC collaboration highlights the need for a proven-path approach to SC collaboration.     

DEVELOPING SOCIAL IDENTITY AND SOCIAL CAPITAL FOR SUPPLY CHAIN MANAGEMENT

Competition involves not firm against firm but rather supply chain against supply chain, but few studies explain theoretically the subsistence of a supply chain as a social entity or the operating mechanisms through which firms socialize to obtain better business performance. On the bases of social identity theory and social capital theory, the authors suggest that the salience of supply chain identity accumulates social capital in a supply chain, which then facilitates supply chain management and improves business performance.

An integrated approach to managing extended supply chain networks

In an effort to improve their competitive position in a rapidly changing marketplace, many companies have replaced their traditional supply chains with extended supply chain networks built on a foundation of supply chain collaboration. These extended networks require the use of decision support tools and technologies to improve both operating efficiencies and customer service, but many companies have struggled to realize the expected benefits of these tools and the increased collaboration. This article recommends that companies adopt an integrated strategy of people, processes, and technology to achieve their competitive supply chain goals. Our recommendation is backed by the results of a survey we conducted of senior-level practitioners concerning the importance and challenges of supply chain collaboration. The article concludes with a set of managerial recommendations to improve a company’s collaborative efforts within its supply chain.     

An improved method for managing catastrophic supply chain disruptions

This article analyzes the differences between frequent and rare risks for supply chain disruptions, and proposes a new, improved risk measurement and prioritization method to account for the characteristics of rare risks. The varying idiosyncrasies of decision makers are integrated into this method such that risk management can be brought into alignment with an individual manager's preferences. Also woven into this tapestry is the notion of detection, which is familiar to those who have applied failure modes and effects analysis (FMEA), but novel in the arena of supply chain risk management. Rare risks in the supply chain are, by their nature, unsettling: unforeseen disruptions are always present, probability estimates are imprecise, and comprehensive data collection is impossible. These difficulties are taken into account by the presented risk management framework. While the proposed ordinal scales are perhaps unsettling to many who desire greater precision, measurement methods must fit the precision that is possible. By considering rare risks along with frequent risks, managers can be better positioned to deal with the unforeseen.     

Second-Hand Markets and Intrasupply Chain Competition

We consider a monopolistic supply chain consisting of a manufacturer and a retailer (service provider) who in addition to selling new durables, buy and resell used ones. The supply chain provides services for both new and used goods. Accordingly, consumers incur service charges for all types of goods. This study is motivated by the modern trend in cell phone businesses where retailers commence buying used phones from customers willing to upgrade their phones. The used phones are then refurbished and resold along with the services. The question that this trend gives rise to is how the interaction with the secondary market affects the performance of the supply chain in terms of its intracompetition and thereby its profit. We show that for a wide range of service rates, the second-hand market coordinates the supply chain by either reducing the double marginalization effect or by offsetting it with extra profits gained by servicing the used goods. This, however, does not imply that both parties always improve their profits. Furthermore, we find that when the service rates are low, the supply chain would be better off if the goods were not durable thereby precluding the very existence of the second-hand market.     

THE BENEFITS OF USING E‐BUSINESS TECHNOLOGY: THE SUPPLIER PERSPECTIVE

The use of e‐business technologies between supply chain organizations has primarily been examined from the viewpoint of buying firms or retailers, with little attention given to the benefits accrued to suppliers. Further, previous studies have been limited to either financial or marketing performance measures, or a narrow range of operational measures. This study builds on research in this area by testing a model of the relationship between supplier use of e‐business technologies in communication with their primary buyer, degree of buyer‐supplier coordination, and a complete set of benefits that include strategic and operational performance measures. Using data from 241 first‐tier OEM suppliers in the computer industry, the findings show that supplier use of e‐business technologies positively impacts organizational benefits both directly and indirectly by promoting buyer‐supplier coordination.     

Exploring the governance mechanisms of quasi-integration in buyer-supplier relationships

This article deals with quasi-integration governance mechanisms in the context of business-to-business buyer-seller relationships. Based on transaction cost analysis and resource dependence theory, the authors identify four key elements of quasi-integration: legal contract, joint problem solving, joint planning, and collaborative communication. From the perspective of resource dependence theory, the authors examine the effects of interdependence on these four elements. Empirical evidence derived from a study of 398 Chinese companies indicates that (1) the four governance mechanisms of quasi-integration are driven by inter-firm dependence; and that (2) legal contract serves as an important foundation of joint problem solving. In addition, the authors examine the distinct effects of the four elements on two critical exchange outcomes: supplier performance and buyer commitment. Their analysis shows that legal contract, joint planning, and collaborative communication positively affect supplier's performance, while joint problem solving and collaborative communication significantly enhance the buyer's commitment to the relationship.
