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.     

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.     

THE SUCCESSFUL CROSS‐DOCK BASED SUPPLY CHAIN

A supply chain using the cross‐dock approach can speed goods from upstream suppliers to downstream customers quickly and cost‐effectively, with benefits to the entire chain, if the appropriate type of cross‐dock is chosen and then designed, staffed and managed for effective performance. Unlike a warehouse, which offers storage, a cross‐dock is a high performance rapid transit point that does not provide storage. Although cross‐docks have been studied with some thoroughness, what has not been seen clearly is that a cross‐dock does not operate in isolation and therefore can't be optimized independently from the upstream and downstream processes. To be successful, cross‐dock optimization makes demands for high performance on all members of the supply chain in terms of speed, effective planning, high reliability, near error‐proof processes and a high degree of transparency, visibility and information‐sharing; accordingly, the article refers to this integrative perspective as a “cross‐dock based supply chain.” To make clear this interdependency between the cross‐dock and the chain based on it, a new definition that classifies types of cross‐dock based supply chains is offered. To assist scholars analyzing and industry management choosing a cross‐dock approach, cross‐dock based supply chains are classified as falling into three different types. Lastly, based on field work in industry and on literature review, nine critical success factors for cross‐dock based supply chain operations are offered.     

Aligning supply chain design for boosting resilience

Many researchers have analyzed the effect of disruptive events, such as natural disasters and economic and market forces, on global supply chains. However, there is a lack of consensus on delineating a universal collection of supply chain risk management practices that will help companies operate in a global market with large-scale disruptions. In this article, we present an analysis, in conjunction with a worldwide online survey, based on successful global brands and their supply chains. We propose a framework that deploys the dynamics of building supply chain resilience, first linking the design of the supply chain portfolio (local versus global scope, as well as strategic responsiveness versus cost reduction) with supply chain vulnerabilities (external versus internal). We describe the transition between different supply chain structures as a way of coping with disruptions and thus proactively developing resilience. In this article, we introduce both a supply chain risk management approach and the reactive-by-deployment mode, as illustrated by successful global company examples.     

SUPPLY CHAIN CAPITAL: THE IMPACT OF STRUCTURAL AND RELATIONAL LINKAGES ON FIRM EXECUTION AND INNOVATION

Firms invest millions of dollars annually in developing their supply chains, with the broad goal of increasing their own performance. However, despite the significant resources deployed for supply chain development, the extent to which initiating, maintaining, and managing supply chain relationships contributes to firm success remains unclear. The current article provides conceptual development supporting the valuation of firm‐to‐firm supply chain connections from the perspective of the focal firm. Based on the social network and economics literatures, the article introduces the concept of supply chain capital, which comprises the value of both the structural configuration and relationship content of the firm's supply chain network. Following theoretical development, a non‐exhaustive set of propositions are constructed illustrating multiple ways that supply chain capital can be accrued and exploited for firm‐level benefit. Managerial recommendations for investment in supply chain capital are included, as are future directions for research in the area of supply chain networks.     

Shopping in the omnichannel supply chain under price competition and product return

In recent years, omnichannel retailing has created value for prospective consumers. The rise of omnichannel retailing has changed consumers' buying habits, and manufacturers are facing stiff competition from retailers. To reduce this competition effect, manufacturers and retailers often work together to reduce showroom display costs. Despite this practice, there is little understanding of how omnichannel retailing impacts supply chain (SC) profit under competitive conditions. We investigate the test-in-store-and-buy-online (TSBO) retailing strategy and its impact on SC profit and price competition between manufacturers. The retailer sells products of both manufacturers through its website but displays products of only one manufacturer in the showroom, which bears the displaying cost. The retailer adopts a return policy for the other manufacturer. Stackelberg game was used to examine how members of the chain interact, and Nash equilibrium was used to find optimal strategies for players under decentralized and integrated channels. The results show that the TSBO strategy in retailing benefits all supply chain players under the integrated channel. A further interesting finding is that omnichannel SC profits are highest when retailers adopt a return policy. When two manufacturers compete and adopt different sales models, the manufacturer who uses the TSBO retail model reaps the most profit. Several other managerial insights are drawn from sensitivity analyses.     

Comments on “Unchained from the chain: Supply management from a logistics service provider perspective”

The paper puts in focus the general observation that traditional supply chain management provides a limited view of supply relationships rooted in a conventional industrial logic, focusing on the physical product, chain relationships and sequential interdependencies. The paper contributes to the aim of extending the view of supply chains - unchaining logistics from the conventional chain structure view - by focusing on how such dominating idea structures can in fact delimit our understanding of, in this case, logistics service providers' contribution to well working supply relationships. The article connects to the discussion by suggesting a much more in-depth reasoning what and how a resource independency perspective can contribute to deepen our understanding of logistics and logistical networks.     

The supply chain implications of recycling

Until recently, end-of-life (EOL) product management was the purview of a small number of firms that could make money out of recycling and/or remanufacturing. Now, changing customer expectations and stringent product take-back regulations are forcing many goods producing organizations to confront EOL product management, even in cases in which there is no clear economic incentive for doing so. This article presents a framework that highlights the supply chain implications for firms forced into EOL product management where recycling is the only viable option. Discussed are the various recycling options available to managers, as well as the strategic implications of each of these choices.     

INTERORGANIZATIONAL TIME‐BASED POSTPONEMENT IN THE SUPPLY CHAIN

This paper presents the results of empirical research on the use of time‐based postponement in a supply chain context using data collected from two manufacturers, a distributor, and a retailer. The analysis shows that implementing postponement at the firm level can result in the supply chain carrying more inventory. In order to achieve its full potential, postponement needs to be implemented across organizations in the supply chain.

Paradoxes and mysteries in virus-infected supply chains: Hidden bottlenecks,changing consumer behaviors,and other non-usual suspects

In the early onset of the COVID-19 pandemic in the U.S., consumers experienced surprising shortages of essential goods that appeared to be unrelated to the pandemic: toilet paper, yeast and flour, and meat cuts. The usual explanations—attributing these shortages to demand spikes—often failed to provide an adequate explanation or predicted only temporary shortages. But these shortages ended up being real supply-chain struggles for which the true causes revealed a deeper set of unusual causes. Our detailed analysis of these supply chains identifies overlooked failure factors and hidden causes. We conclude with the profound lessons learned from the pandemic crisis on supply chains and the implied challenges of building resilient supply chains for the future, which require rethinking the relevant systems we plan and optimize. The level of investment required for building firm-specific redundancy of assets and operational flexibility might be prohibitive for any one firm, or their financial stakeholders, to pursue and accept.     

OVERCOMING SPREADSHEET RISK IN SUPPLY CHAIN MODELING

Spreadsheet optimization modeling plays an important role in the management of today's sophisticated supply chains. However, despite the advantages of spreadsheets (or in some cases because of these advantages) there are significant risks associated with spreadsheet models. Spreadsheet risk is defined as the chance of adverse operational or financial consequences due to erroneous creation, maintenance, and/or use of spreadsheet models. Such errors arise because the intrinsic complexity of optimization models is beyond the expertise of many non‐technical managers. In this article we discuss procedures that we developed for managing the substantial risks associated with the use of spreadsheets for supply chain optimization. The issues we address go far beyond simple data entry mistakes, which are possible in virtually every aspect of business and can never be completely eliminated.     

Dynamics of judicial service supply chains

Behavioral issues, coupled with temporary capacity imbalances, dictate the characteristics that a service supply chain assumes in the long run. The paper looks at a service chain in which two factors, backlogs and incentives, influence human agent processing times and, hence, service supply chain capacity. The paper finds that servers within the supply chain change their processing speeds in order to maintain a backlog of cases that is acceptable and credible. The backlog must not be too small, so as to avoid the impression that work is scant and there is idleness; but it must not be too large, so as to avoid the impression of laziness. Simultaneously, the paper finds that there are implicit incentives in the formal hierarchy that impinge upon throughput rates at certain stages of the supply chain: agents upstream try not to overwhelm their bosses' stations downstream with excess work. Hence, this paper looks at the effects of perceived backlogs within service supply chains and also at capacity unbalances that stem from such incentives. The study explores these issues in the context of a managerial intervention in a judicial service supply chain. The study identifies the structure of a seemingly unstructured decision execution that leads to the observed outcomes. The research results in a preliminary system dynamics model that suggests several operational steps to overcome bottlenecks and incompetency.

THE ROLE OF FOLLOWERS IN SUPPLY CHAINS

Significant attention has been given to the contribution of supply chain leader organizations in the logistics literature. However, the majority of supply chain member firms are not leaders, and the contribution of these supply chain followers has not been described. Arguably the contribution of follower organizations is greater than that of a single supply chain leader since they are found in greater numbers in most supply chains. This paper identifies a conceptual framework of supply chain followership, classified on the basis of the behaviors exhibited by follower organizations. Data was collected via an interactive simulation, using executives as participants. Structural equation modeling was used to evaluate the proposed model. Results indicate that follower organizations make a greater contribution to overall supply chain performance than leaders when transformational behaviors are present.     

How policy is shaping the macro healthcare delivery supply chain: The emergence of a new tier of retail medical clinics

The healthcare industry continues to face substantial pressure to simultaneously improve costs and patient centricity. Much of the focus to date has concerned policy interventions capable of improving these performance measures for traditional healthcare providers, such as hospitals. But recently, nontraditional healthcare providers like Walmart Health and Amazon have made forays into the industry by establishing retail medical clinics (RMCs). These efforts constitute a redistribution of how services are organized across the macro healthcare delivery supply chain. While RMCs stand to bring innovative models of service delivery to patients, the policy environment can both enable and inhibit their involvement in the industry. We develop a framework that explains how structural and conduct regulations have historically influenced demand for and supply of healthcare services. We then describe how these regulatory factors can support nontraditional healthcare providers as they launch innovative service delivery models aimed at efficiency and customer centricity.     

GLOBAL SUPPLY CHAIN RISK MANAGEMENT

Global supply chains face a multitude of risks. A review of the recent literature reveals a few structured and systematic approaches for assessing risks in supply chains. However, there is no conceptual framework that ties together this literature. The purpose of this paper is to integrate literature from several disciplines ‐ including logistics, supply chain management, operations management, strategy, and international business ‐ to develop a model of global supply chain risk management. The implications for stakeholders and how future research could bring more insights to the phenomenon of global supply chain risk management are also discussed.     

SUPPLY CHAIN MANAGEMENT COORDINATION MECHANISMS

There is growing interest from industry and academic disciplines regarding coordination in supply chains, particularly addressing coordination mechanisms available to eliminate sub‐optimization within supply chains. However, there is a disconnect between what is known in academic research about coordination mechanisms and what mechanisms practitioners apply and consider useful. This research fills a gap in the literature by conducting an in‐depth qualitative study of supply chain coordination mechanisms, primarily price, non‐price, and flow coordination mechanisms. Results suggest that: (1) managers prefer flow coordination mechanisms over price and non‐price coordination mechanisms; (2) supply chain orientation and learning orientation are important for the implementation of flow coordination mechanisms; and (3) technology, capital, and volume are not pre‐requisites for flow coordination mechanisms.
