Closed‐Loop Supply Chains: An Introduction to the Feature Issue (Part 2)

Closed‐loop supply chain management is the design, control and operation of a system to maximize value creation over the entire life‐cycle of a product with dynamic recovery of value from different types and volumes of returns over time. The research in this feature issue furthers our understanding of this rich area and serves as a starting point for another round of research which continues to dig deeper still into relevant industry issues.     

基于EVA与经营风险偏好的供应链鲁棒优化模型

在由一个制造商和多个外部供应商构成的多产品、多阶段供应链中,将经济增加值（EVA）作为体现价值创造的绩效指标,并考虑决策者的经营风险偏好,采用已知概率的离散情景描述资本成本与需求的波动情况,利用鲁棒随机规划方法,建立了以价值创造为目标的供应链鲁棒优化模型。应用分析的结果表明,模型能够将供应链的绩效与风险管理结合起来,减少资本成本与需求不确定对目标值的影响,得到具有鲁棒性的最优解,而且越是风险厌恶型的决策者越会为了保持较低的经营风险而放弃较大的EVA值。同时,决策者可选择不同的权重系数侧重于解鲁棒或模型鲁棒,保证供应链运作的鲁棒性,实现价值创造的目标。     

Quality Management in Multi‐Level Supply Chains with Outsourced Manufacturing

Outsourcing stretches supply chains longer with added contract manufacturers responsible for the manufacturing of parts and final products. Should a firm change its quality management approach as its supply chain becomes longer with outsourced manufacturing? This paper studies a brand owner's optimal choice between two commonly used quality management approaches: an inspection‐based approach and an external failure‐based approach, in two supply chains – a dyadic supply chain and a multi‐level supply chain where the brand owner outsources manufacturing to an independent contract manufacturer. Our study finds that the brand owner's optimal choice between the two quality management approaches could be opposite in the two supply chains. Specifically, we show that if agency costs exist between the contract manufacturer and the brand owner, the brand owner may prefer an inspection‐based approach in the multi‐level supply chain in contrast to preferring an external failure‐based approach in the dyadic supply chain. In particular, inspections can be effective for the brand owner to limit the manufacturer's profit by excluding defective finished products and components, which in turn reduce agency costs in the multi‐level supply chain. Hence, the efficiency of an inspection‐based approach relative to an external failure‐based approach can be higher in the multi‐level supply chain as compared to the dyadic one. Our findings suggest that firms should adjust to changes in supply chain structures and re‐evaluate the efficiencies of different quality management approaches accordingly.     

The Informal Sector: A Review and Agenda for Management Research

Despite its connotations of non‐compliance, illegality, social exploitation and marginality, the informal sector is a substantial contributor to economic life in developing countries and, increasingly, in more technologically advanced activities. Its prevalence in developed economies has also become more widely recognized. In light of its significance, this paper reviews research on the informal sector from a management and organization scholarship perspective, rather than from an entrepreneurship view, as has been the focus until now. It sets out the atypical management practices that are inherent in the sector, explores the under‐researched relationship between formal and informal firms, and highlights definitional, conceptual and other limitations in extant research. As a step in resolving these issues, the authors present a conceptual model of formality and informality in a three‐dimensional framework that highlights an organizational infrastructure dimension, a view of firms operating along a continuum, and a multi‐level analytical context. Building on this, the authors detail opportunities for enhanced appreciation of in situ management and organizational practices in the informal sector and outline tools for pursuing a management and organization scholarship agenda. Overall, the authors argue that management scholarship has great potential to improve understanding of the informal sector, and that the informal sector provides opportunities to advance management theory, research and practice.     

REALIZATION OF THE VIRTUAL ENTERPRISE PARADIGM IN THE CLOTHING INDUSTRY THROUGH E‐BUSINESS TECHNOLOGY

This paper presents a methodology and a case study for supply chain management in the clothing industry that makes extensive use of the virtual enterprise paradigm. The main research goal was to design and implement a prototype e‐business software component and carry out tests in several industrial users. The research effort resulted in the extended production data management system (epms), which supported the business processes of customer order management, subcontractor selection, and multi‐site/multi‐firm production orders release. The enablers of this software application were business‐to‐business (b2b) e‐commerce technologies in the operating context of application service providers (asps).     

Value of Information in Closed Loop Supply Chains

We explore the value of information (VOI) in the context of a firm that faces uncertainty with respect to demand, product return, and product recovery (yield). The operational decision of interest in matching supply with demand is the quantity of new product to order. Our objective is to evaluate the VOI from reducing one or more types of uncertainties, where value is measured by the reduction in total expected holding and shortage costs. We start with a single period model with normally distributed demands and returns, and restrict the analysis to the value of full information (VOFI) on one or more types of uncertainty. We develop estimators that are predictive of the value and sensitivity of (combinations of) different information types. We find that there is no dominance in value amongst the different types of information, and that there is an additional pay‐off from investing in more than one type. We then extend our analysis to the multi‐period case, where returns in a period are correlated with demands in the previous period, and study the value of partial information (VOPI) as well as full information. We demonstrate that our results from the single period model (adapted for VOPI) carry‐over exactly. Furthermore, a comparison with uniformly distributed demand and return show that these results are robust with respect to distributional assumptions.     

Managing Internet Product Returns: A Focus on Effective Service Operations

Product returns present one of the biggest operational challenges in the world of Internet retailing due to the sheer volume and cost of processing returns. But returns also represent an often‐missed opportunity to manage customer relationships and build customer loyalty to the retailer. Based upon data from a survey of 464 customers of five different Internet retailers, this article explores how firms' returns management systems affect loyalty intentions. We draw upon extant literature in the fields of Internet retailing, service quality, supply chain management, and customer satisfaction/loyalty to develop a model and a set of hypotheses relating ten latent variables in the service returns offering area. Our resulting structural equation model provides evidence of the impact of the returns management system upon customer loyalty intentions. The model also identifies effects on loyalty intentions arising from customers' satisfaction with, and perceptions of, the value of the returns service offered. These findings will help inform managers' choices regarding investment in the returns management system as an element of service quality improvement and a potential means of improved profitability. In addition, this study's empirical exploration and testing of a returns management model in the Internet retailing environment is a contribution to the currently underrepresented body of academic literature linking marketing and supply chain management in the context of end consumers.     

Managing Knowledge Creation in High‐Tech R&D Projects: A Multimethod Study

R&D projects in high‐tech organizations bring together diverse knowledge domains to quickly develop new products and processes. The fast‐paced context of high‐tech organizations makes it challenging to create new knowledge and solve complex problems. Managing these R&D projects requires understanding both the mechanisms and the type of knowledge created to achieve project objectives. This research conducts a two‐phased multimethod study to understand knowledge creation in high‐tech R&D projects. The first phase uses qualitative data to develop a theory on knowledge creation in R&D projects. The second phase involves a survey that collects data from R&D projects to test the theory. Results from the case study find that R&D projects benefit from two types of knowledge – objective and intuitive. The case analyses show that intuitive and objective knowledge creation in high‐tech organizations occurs by creating not only diverse but also psychological safe project teams. The large‐scale survey finds that team diversity positively influences objective knowledge creation while psychological safety affects intuitive knowledge creation. Surprisingly, the results show that team diversity negatively affects intuitive knowledge creation. A post hoc analysis takes a more granular look at diversity and shows that different kinds of diversity have different effects on knowledge creation. This helps to better explain how to manage innovation across boundaries. Finally, the analysis shows that both objective and intuitive knowledge influence R&D project performance. Taken together, these results help explain how to manage innovation across functional boundaries to create knowledge and enhance R&D project performance.

An actor-network perspective on business models: How ‘Being Responsible’ led to incremental but pervasive change

Business models have been studied as organizational value logics, which manifest in the states of cognition, artefacts, and activities. There is no conceptual perspective integrating all three of these states yet. In response, this paper develops a conceptual scaffold of an actor-network perspective: Value logics become programs of action as they are embodied in human actors’ cognition and inscribed into artefacts, forming actor networks that enact business model activity systems. An in depth case study of The Company (anonymized) and of its corporate responsibility initiative ‘Being Responsible’ illustrates the empirical application of this perspective. An analysis of 104 interviews with 72 individuals shows how The Company's business model was enacted by a network of human and nonhuman actors. The Being-Responsible artefact engaged in translation through which it enrolled business model actors to enact a responsibility logic in addition to their commercial logic. This changed the business model incrementally, but pervasively. The paper contributes (1) an integration of existing theory on business model logics manifesting cognition, artefacts, and activities in an actor-network perspective, (2) an extension of research on artefacts, exploring their agency when not explicitly related to the business model; and (3) the development of substantive theory that explains incremental, pervasive business model change through distributed processes of translation. The translation perspective also holds promise for explaining the dynamics of business model creation, maintenance, and radical business model change.     

Measuring management quality in the factory

The last decade has seen a growing consensus that manufacturing matters. The factory as the producing unit is the core of the firm's manufacturing activities. However, even now, it is not agreed on or even fully understood what constitutes a well-managed factory. This article attempts to create a causal model of management quality in the plant, identifying key managerial levers for improving plant performance. The model is based on an integrated view of three core processes: supply chain, product and process development, and strategy deployment. We postulate that the joint performance of the three processes is determined by the quality with which they are managed. Management quality is operationalized as consisting of six types of action: delegation (or decentralization), integration (or coordination), measurement, employee participation, communication, and employee development.This management quality model has been applied to the design of the Top Usine 1995 Best Factory Award administered in cooperation with the French weekly L'Usine Nouvelle. Data collected from participating plants do substantiate our view that plant performance is substantially driven by management quality: the six management quality dimensions are shown to be statistically linked to performance improvement rates in the plant, and we provide further evidence of this link by detailing the case example of the award winner. Our survey also shows that supply management appears to be a common problem area for the factories participating in the Top Usine award, including the best ones.     

Improving Humanitarian Operations through Technology‐Enabled Collaboration

Humanitarian supply chains involve many different entities, such as government, military, private, and non‐governmental organizations and individuals. Well‐coordinated interactions between entities can lead to synergies and improved humanitarian outcomes. Information technology (IT) tools can help facilitate collaboration, but cost and other barriers have limited their use. We document the use of an IT tool to improve last‐mile supply distribution and data management in one of many camps for internally displaced persons after the January 2010 earthquake in Haiti, and we describe other current uses of technology in camp management. Motivated by these examples and the interest among humanitarian organizations in expanding the use of such tools to facilitate coordination, we introduce a cooperative game theory model and explore insights about the conditions under which multi‐agency coordination is feasible and desirable. We also outline an agenda for future research in the area of technology‐enabled collaboration in the humanitarian sector.     

Sensing Abnormal Resource Flow Using Adaptive Limit Process Charts in a Complex Supply Network*

Supply networks are becoming increasingly complex with multiple overlapping relationships between firms that may span across industries. Consequently, inventory management is becoming more difficult as managers have to cope with variability in the supply flows that originate from different parts of the network. Managers that quickly sense abnormal flows may intervene and adapt their inventory policies in response to system changes. In this article, we present a framework for sensing abnormal flows originating within the upstream supply network of a focal organization. Our framework combines time series modeling with process charts to identify abnormal flow patterns in the incoming supply streams. It is a flexible framework that uses off‐the‐shelf technology to provide managers with a process that can be employed for monitoring multiple individual or aggregated data streams originating within any complex system such as complex adaptive supply networks. We illustrate our framework on four years of longitudinal supply data from the second largest food bank in the United States. We identify multiple instances of abnormal supply flows and validate our results through rigorous inventory analysis as well as field‐based expert interviews. We discuss the implications of our findings for inventory management in complex supply networks, both from academic and practitioner points of view.     

Impact of strategic and operational risk management practices on firm performance: An empirical investigation

Increasingly, creating and delivering value through complex supply chain networks involves substantial risks. However, strategy development under business risk conditions is not well-understood. This cross-country research examines how, under conditions of supply chain network risk, firms develop effective risk management practices. Using a literature review and survey research of managers from global firms; we present a research model, and empirically test the hypothesized relationships. The results show that under conditions of uncertainty, management decision-making is more likely to be cautious until visible forms of risks emerge, and prudent response mechanisms are put in place. This study identifies the crucial role of supply chain exploration and exploitation practices, and their influence in development of network risk management practices, leading to competitive financial outcomes.     

A classification of resources for employee-based value creation and a future research agenda

This conceptual paper aspires to provide a theoretically sound understanding of the value creation process of a specific value network (i.e., firm–employee context). Drawing on service-logic and resource-based frameworks, a classification of four diverse resource types in an organizational context is introduced (i.e., core, augmented, add-on, peripheral resources), based on their exchangeability and their contribution to employees’ value creation and co-creation. This classification enables a better understanding of the nature and the unique features of different firm–employee exchanges in an organizational context, and delineates each type’s distinctive role in employee-based value creation activities. Four propositions derive from this classification; this suggests that not all resource types can be exchanged and that the relative contribution of various firm–employee exchanges to value creation is asymmetrical. A future research agenda is also presented, discussing the potential implications of this classification for contemporary organizations.     

The Social Construction of Risk in a Rural Community: Responses of Local Residents to the 1990 Hagersville (Ontario) Tire Fire

This paper presents the findings of research relating to the 1990 Hagersville (Ontario) tire fire. After reviewing the literature on risk and risk perception, it begins by describing the event as well as the community in which it occurred. The reasons for adopting a qualitative research design are then established practical, conceptual, and methodological. The residents' accounts of the fire, evacuation, and aftermath in terms of concerns, anxieties, and responses are described. Five themes emerge: economic, community, health, environmental, and governance. The paper concludes by putting forward a case study-derived model of risk appraisal and management, and by relating the findings to policy issues.     

随机订单干扰下考虑合并决策的供应链网络调度研究

为满足客户个性化需求的快速响应，企业需具备柔性的外部供应链网络结构，以协同方式共同完成产品生产。本文考虑具有交互特征的多个不同类型协同供应链网络，构建生产成本、库存成本、等待成本以及订单延期交货成本最小化的目标函数，并设计合并决策判断变量构建同类订单在相同协同企业处的开始时间约束。此外，模型中考虑确定订单以及随机订单两种类型订单，并设计随机订单在区间时间段中离散时间点的到达概率。为获取协同供应链网络生产调度优化策略，基于随机订单到达与否的场景构建四个子决策模型，并进一步设计判断提前安排随机订单协同生产和不提前安排随机订单协同生产不同调度策略下成本差异的主决策模型。仿真结果表明合并决策在带来生产成本效益的同时也引起了部分订单的延期交货，且不同类型的协同供应链网络对随机订单的抗干扰能力存在一定程度的差异。     

MANAGING PRODUCT VARIETY: AN INTEGRATIVE REVIEW AND RESEARCH DIRECTIONS

Variety management has emerged as a crucial dimension of successful business practice. In this paper, I first provide a framework for managerial decisions about variety. Variety‐creation decisions determine the amount, type, and timing of end‐product variety, while variety‐implementation decisions focus on the design and operation of internal processes and a supply chain to support a firm's variety‐creation strategy. I organize variety‐related decisions into four key decision themes in variety creation: 1) dimensions of variety, 2) product architecture, 3) degree of customization, and 4) timing; and three key decision themes in variety implementation: 1) process capabilities, 2) points of variegation, and 3) day‐to‐day decisions. I describe each theme and review the relevant literature on each theme, with a focus on research that provides insight to problems faced in practice. Finally, I identify untapped avenues for future research that would be of value to the practicing manager, paying special attention to interdependencies among decision themes.     

Deconstructing the Way in which Value Is Created in the Context of Social Entrepreneurship

According to existing literature, the core of social entrepreneurship (SE) knowledge is evolving and, as such, it has made important contributions to theoretical definitions and essential characterizations. However, more theoretical issues need to be addressed before the SE field can be fully explained and understood. In particular, the authors observe in the literature that, within empirical or conceptual studies, almost all authors use the term ‘value’, but seemingly assume the dimensions of value rather than define or analyse its connotations and components. This paper uses the value construct and its multi‐faceted dimensions to deconstruct the way in which value is created in the SE context. The authors argue that an analysis based on value generation, value capture and value sharing provides important insights into the specificity of SE research and can facilitate future theorizing. Through the conceptual lens of this central concept of value emanating from value theory and business model literature, the authors abductively analyse and classify the studies, providing a practical resource. The authors discuss the phenomenon, presenting an integrative framework that facilitates a clearer understanding of the social value creation process and suggest future research areas as openings for theory development in relation to value creation, its main components and flows.     

Managing Disruption Risks in Supply Chains

There are two broad categories of risk affecting supply chain design and management: (1) risks arising from the problems of coordinating supply and demand, and (2) risks arising from disruptions to normal activities. This paper is concerned with the second category of risks, which may arise from natural disasters, from strikes and economic disruptions, and from acts of purposeful agents, including terrorists. The paper provides a conceptual framework that reflects the joint activities of risk assessment and risk mitigation that are fundamental to disruption risk management in supply chains. We then consider empirical results from a rich data set covering the period 1995–2000 on accidents in the U. S. Chemical Industry. Based on these results and other literature, we discuss the implications for the design of management systems intended to cope with supply chain disruption risks.
