Efficient location of industrial activity cells in a global supply chain

Inefficient locations for production, distribution and reverse logistics plants will result in excess costs no matter how well material requirements planning (MRP), inventory control, distribution and information sharing decisions are optimized. In this paper we study ways in which aspect of activity cell location decisions can be analyzed within an extended MRP model. This model has previously been extended by including distribution and reverse logistics components in a compact form, presented in Grubbström et al. (2007). Our aim is to demonstrate the basic differences between an approach to location problems with MRP “under the same roof” as the global supply chain, in which transportation time delays and direct transportation costs have substantial influence. We discuss possibilities of how to present location aspects in the supply chain model obtained from combining input–output analysis and Laplace transforms in four sub-systems, namely manufacturing, distribution, consumption and reverse logistics, and show how the transportation costs and lead time influenced by the location of all these activities affect the resulting net present value (NPV). Our aim is to build a model supporting decisions concerning the structure of a supply chain as an alternative to a mixed integer programming formulation. The model developed is based on the use of continuous functions describing spatial distributions of cost and customer demand. Continuous functions are embedded in the MRP extension previously introduced in Grubbström et al. (2007).Location decisions influence (i) production costs, because timing influences the cost of activities involved in creating a product, cf. (Grubbström and Bogataj, submitted for publication), and (ii) logistics costs, which refer to the procurement and physical transmission of materials through the supply chain. In this current paper we wish to combine both of these aspects into a comprehensive model, where we show the interaction between the “space of flows” and the “space of places” as Giovanni Arrighi distinguishes one from the other in his book The Long Twentieth Century.     

SHRM Theory in the Post‐Huselid Era: Why It Is Fundamentally Misspecified

This article critiques the theoretical model that dominates mainstream research in strategic human resource management. Contributions include: the critique is developed from an explicit model of the employment relationship; new concepts of “weak contingency” and “strong contingency” are introduced; the standard hypothesis of a positive sign on the human resource management variable in firm performance studies is shown to be incorrect for a competitive economy (it should be zero); and the analysis is based on “first principles” of institutional economics and industrial relations.     

The Long Tail of the Auto Industry Life Cycle

This article explores how the industry life‐cycle theory, proposed by Abernathy and Utterback, can be reinterpreted from the viewpoint of product architecture dynamics. The “long tail” of the automobile industry life cycle, observed during the past several decades, is explained by an evolutionary framework in which a product's architecture is treated as an endogenous variable affected by customers' functional requirements, environmental‐technical constraints, and their changes. The present article explains how the existing industry life‐cycle model effectively explains the early history of automotive product‐process innovations, but that it fails to explain the “long tail” of the life cycle, and that an evolutionary approach of product architectures can be used to explain the architectural sequence and the long‐term trend of the increase in nonradical innovations. That is, the industry life‐cycle model certainly fits well with the actual pattern of product‐process innovations at the early phase of the automobile's development, between the 1880s (invention) through the 1920s (the end of the Model T) and into the 1960s, when product differentiation continued without significant product/process innovations (e.g., the Big Three's annual model change). But the question remains how this model can explain the rest of the industry's history (1970s to 2010s), which is characterized by “rapid incremental innovations,” or a “long tail of the life cycle,” with its upward trend of technological advancement rather than the end of innovations or the beginning of another industry life cycle (i.e., “dematurity”). The evolutionary framework of product architecture predicts that the macro architecture of a given product category (e.g., passenger cars) will be relatively integral when the functional requirements that customers expect, the constraints imposed by society and the government, and the physical‐technical limits inherent in the product are strong, and that it will be relatively modular when they are weaker. The dynamic architectural analysis starts from the Lancaster‐type analysis of a set of function‐price frontiers for a given product category (e.g., cars). Based on the design theories, it hypothesizes that the shape of function‐price frontiers are different between integral models and modular models. It then hypothesizes that price‐oriented customers tend to choose relatively modular products, whereas function‐oriented customers choose relatively integral products more often than not, other things being equal. Thus, the macro architecture of a given product can be determined depending on whether each architecture's price‐function frontier touches the price‐function preference curves of its customers. As for the future architecture of the car, its macro architecture, determined by markets and environments, will remain relatively integral and complex as long as it continues to be a fast‐moving heavy artifact in the public space, whereas its micro architecture, determined by engineers, will be somewhat mixed, as the engineers try to simplify and modularize the automobile design wherever the market and technology permit. The evolutionary framework of architectures also predicts that the architectural sequence inside the industry life cycle will differ by products (e.g., cars and computers) depending upon the dynamic patterns of technological advancement (e.g., shifts of the price‐function frontier) and market‐societal constraints (e.g., shifts of the price‐function preference curve).     

Outsourcing reverse logistics of high-tech manufacturing firms by using a systematic decision-making approach: TFT-LCD sector in Taiwan

Reverse logistics are increasingly crucial for the supply chain strategy of global high-tech manufacturing firms. As reverse logistics operations are significantly more complex than traditional manufacturing supply chains, many high-tech manufacturers are examining the feasibility of outsourcing reverse logistics activities to third party logistics providers (3PLs) from a strategic planning perspective. Internal resources and capabilities are thus examined from a resource-based perspective to identify which reverse logistics service requirements could be fulfilled in-house or outsourced. Therefore, this work presents a systematic approach using the analytical network process (ANP) not only to investigate the relative importance of reverse logistics service requirements, but also to select an appropriate 3PL. Empirical results based on the case of the TFT-LCD sector in Taiwan indicate that information technology management is of priority concern in reverse logistics services. In addition to providing a valuable reference for manufacturers concerned with service requirements for outsourcing, results of this study significantly contribute to the efforts of 3PLs in evaluating whether they comply with potential customer requirements based on their service capabilities.     

Production planning of a hybrid manufacturing-remanufacturing system under uncertainty within a closed-loop supply chain

This paper deals with the production planning and control of a single product involving combined manufacturing and remanufacturing operations within a closed-loop reverse logistics network with machines subject to random failures and repairs. While consumers traditionally dispose of products at the end of their life cycle, recovery of the used products may be economically more attractive than disposal, while remanufacturing of the products also pursues sustainable development goals. Three types of inventories are involved in this network. The manufactured and remanufactured items are stored in the first and second inventories. The returned products are collected in the third inventory and then remanufactured or disposed of. The objective of this research is to propose a manufacturing/remanufacturing policy that would minimize the sum of the holding and backlog costs for manufacturing and remanufacturing products. The decision variables are the production rates of the manufacturing and the remanufacturing machines. The optimality conditions are developed using the optimal control theory based on stochastic dynamic programming. A computational algorithm, based on numerical methods, is used for solving the optimal control problem. Finally, a numerical example and a sensitivity analysis are presented to illustrate the usefulness of the proposed approach. The structure of the optimal control policy is discussed depending on the value of costs and parameters and extensions to more complex reverse logistics networks are discussed.     

A Sensitivity Analysis of IRR Leasing Models

In this article we argue that advances made in automation, communication, and manufacturing portend a dramatic reversal of the “bigger is better” approach to cost reductions prevalent in many basic infrastructure industries; for example, transportation, electric power generation, and raw material processing. We show that the traditional reductions in capital costs achieved by scaling up in size are generally matched by learning effects in the mass production process when scaling up in numbers instead. In addition, using the U.S. electricity generation sector as a case study, we argue that the primary operating cost advantage of large unit scale is reduced labor, which can be eliminated by employing low-cost automation technologies. Finally, we argue that locational, operational, and financial flexibilities that accompany smaller unit scale can reduce investment and operating costs even further. All of these factors combined imply that with current technology, economies of numbers may well dominate economies of unit scale. Yet realizing the full potential of small unit scale will require technologists and business leaders to develop a new ability to “think small.”

Co-management of purchasing and marketing: Why,when and how?

This article discusses the theoretical and conceptual foundations for the co-management of purchasing and marketing and thereby provides some answers to the questions, why, when and how purchasing and marketing should be co-managed. It develops a conceptual framework distinguishing between internal and external co-management of purchasing and marketing. Improving value creation and value capture is identified as a necessary “pull factor” driving the co-management of purchasing and marketing. Based on resource dependence theory (RDT), we argue that dependence on critical resources is another important “push factor” for the emergence of external co-management. We present a RDT-based typology of co-management constellations showing that co-management is not a one-size-fits-all approach and summarize our findings in five propositions on the co-management of purchasing and marketing. In sum, we conceptualize co-management of marketing and purchasing as a bridging strategy that allows a focal firm to accommodate dependence on critical upstream and/or downstream resources and improves value creation within the supply chain.     

Analyzing supply chain robustness for OEMs from a life cycle perspective using life cycle simulation

Long-term relationships between original equipment manufacturers (OEMs) and stakeholders in their supply chain and end-of-life process can be designed, while considering uncertainty in future environmental legislation changes. This study proposes a method to analyze the capability of OEMs to reconfigure their supply chain and end-of-life operations to achieve performance targets, which are defined in terms of environmental impacts and life cycle costs. Using life cycle simulation (LCS), the physical deterioration and the functional obsolescence of individual products are considered as stochastic elements in the analysis. The analyzed reconfiguration capability provides the OEM with robustness against uncertainty from a life cycle perspective.

Do External Knowledge Sourcing Modes Matter for Service Innovation? Empirical Evidence from South Korean Service Firms

To source external knowledge, firms in the service area use various sourcing modes simultaneously suitable for their internal needs or external environments. Each external knowledge sourcing mode has distinctive characteristics, and as such, they can offer different advantages and/or disadvantages to the firms. Thus, the effects of external knowledge sourcing on service innovation may vary depending on the sourcing modes. The current study aims to empirically examine the different effects of various external knowledge sourcing modes on service innovation. The study identifies three external knowledge sourcing modes: joint development, technology purchasing, and external information acquisition. Three hypotheses are established to examine the relationships between the extent of utilizing each mode and service innovation performance in terms of new service introduction. The data for analysis are selected from the “Korean Innovation Survey 2006: Service Sector” (KIS 2006). It is regarded as South Korea's version of the Community Innovation Survey (CIS). The KIS 2006 data set covers joint development, technology purchasing, and external information acquisition activities of corporations in the service sector in South Korea. The study empirically analyzes the data set using a negative binomial regression model. The results first demonstrate that the extent of the joint development has an inverted U‐shaped relationship with the service innovation performance. Second, the results indicate that, on the other hand, service innovation performance decreases with the increase to the extent of the technology purchasing when the extent is below the threshold. On the other hand, it increases with the increase to the extent of the technology purchasing; this occurs when the extent exceeds the threshold. Third, the results show that external information acquisition has a positive effect on service innovation performance. These findings support that the extent of utilizing each mode has different relationships with service innovation performance. The findings suggest that service firms need to utilize joint development at a moderate level, active technology purchasing, and as much external information acquisition as possible to maximize service innovation performance. In practice, this finding can help managers of service firms select appropriate external knowledge sourcing modes and determine the optimum level of use for each mode. This study also can help firms build up strategies for external knowledge sourcing.     

What Is Best for Workers? The Implications of Workplace and Human Resource Management Practices Revisited

Drawing on a 2003–2004 random household telephone survey of 750 Canadian workers, I explore the implications of work and human resource (HR) practices for six aspects of the quality of working life. I find “traditional” HR practices, associated with the bureaucratic model predominant after World War II and with union representation, to have strong positive implications for workers. Participative workplace practices also have strong positive implications, although these are largely limited to information sharing in the union sector. The actual organization of work (e.g., teams), contingent pay, and “new” HR practices, associated with the “new” HRM of the 1980s, all make little difference. Comparison of these findings with those from a comparable 1998 survey of 508 Canadian workers and a parallel 2003 survey of 450 English workers suggest, however, that the implications of work and HR practices may be historically and institutionally contingent and thus should be interpreted using a historical/institutional perspective.     

The impact of purchase situation on salesperson communication behaviors in business markets

This research addresses the impact of purchase situation on sales communication behaviors used by the salesperson in business markets. We hypothesize that different sets of sales communication behaviors will be needed and vary for different purchasing situations. Measures of a salesperson's communication behaviors were tested for different types of purchase situations. Differences were found in the persuasiveness of the salesperson's getting, giving, and using information, depending on the type of purchase situation. These findings help support the value of salesperson adaptability, providing an important variable on which to adapt.     

Purchasing as market-shaping: The case of component-based software engineering

The efforts to address markets as socio-technical orders have hitherto focused on the role of marketing in shaping demand. However, in many markets the role of purchasing is just as important. This paper uses a case study to examine how a single buying company can attempt to shape an emerging market through its purchasing practices. As a result, the study identifies five types of market-shaping actions. Within each action type, the market-shaping behavior of a buyer in an emerging market can be very diverse and include internal actions as well as actions aimed at influencing other market actors. While agency on the purchasing side is often associated with large size organizations, namely government and public sector agencies, our case study shows that agencies on the purchasing sides can be deployed in a variety of ways rather than merely through raw bargaining power. The findings indicate that buying firms do not simply adjust their own purchasing processes according to existing offerings, but actively attempt to drive market evolution in particular directions.     

Agency,structure, and the dominance of OEMs: Change and stability in the automotive sector

Research summary: This article reviews structural change in the automotive sector from 1997 to 2007. We find that, following internal framing contests, Original Equipment Manufacturers (OEMs) led efforts to change their sector's architecture, starting from both strong and weak competitive positions and working with suppliers to advocate a new vision based on modularity and outsourcing. As the risks and costs of this vision became apparent, OEMs were able to reverse course and reaffirm their hierarchical control on the sector, taking advantage of structural features that weren't salient ex ante. We consider why certain OEMs initiated this status‐quo challenging change, and identify how sector structure mediated their (and suppliers') efforts to implement it. We document the complex change process, driven by agency, structure, and heterogeneity in firms' understanding of their sector's architecture. Managerial summary: We study the “industry architecture” (i.e., division of labor and profit) of the automotive sector. During the late 1990s, Original Equipment Manufacturers (OEMs) embraced a new vision, based on “Modularity + Outsourcing,” inspired by an analogy with Personal Computers (PCs). This seems puzzling since such a change was hard to implement and could have led to OEMs relinquishing strategic control of the sector. The misstep was caused by internal framing contests and the agendas and influence of suppliers, consultants, and academics. We also consider why OEMs were able to partially reverse these changes, and document the role of structural features that let them control their sector and retain value: managing the customer experience, acting as guarantors of quality, and preserving hierarchical supply chains in which they functioned as system integrators.

Sustainable value propositions: Framework and implications for technology suppliers

Advances in sustainable purchasing put pressure on firms to evaluate and demonstrate the sustainability of their products and services. In this paper, we coin the term sustainable value proposition, develop a process framework for building sustainable value propositions, and illustrate its application with two technology-intensive offerings. By integrating the literature on sustainable marketing and customer value propositions with life cycle assessment methodologies, we build a process framework that can be applied to demonstrate and evaluate the economic, environmental and social benefits of industrial products and services. The framework comprises 1) identification of potential impacts, 2) identification of key value creation mechanisms, 3) choosing key indicators, 4) life cycle modeling, and 5) life cycle value demonstration. Through two case studies, we examine the development of sustainable value propositions in two industry sectors: metallurgical and automotive. The results highlight the value provided to customers through the combination of direct economic benefits and derivative benefits of reduced environmental and social impacts. Our paper contributes to the growing field of sustainable marketing by offering guidelines on how to integrate sustainability with the marketing and purchasing of technology-intensive offerings. In addition, we offer guidelines for how to construct sustainable value propositions that resonate with customers.     

Flexibility and quality in logistics and relationships

This research focuses on supplier-buyer relationships in a distribution channel. It uses a contingency theory to claim that, under different environmental conditions, logistics flexibility and relationship flexibility for a focal firm (a manufacturer in this study) will have distinct effects on logistics service quality (when treated as a controllable mediator) and the firm's satisfaction in its relationship with its key downstream account. Using data from a survey of manufacturers in China, it uses structural equation modeling to test the main effects and moderated regression together with moderated path analysis to examine the contingent effects of environmental uncertainty. The results show that, as distinctive capabilities, both logistics flexibility and relationship flexibility have significant positive effects on the level of logistics service quality that the manufacturer offers, which, in turn, enhance how much it values and is satisfied with its relationship with its key account. However, the direct effect of logistics flexibility on relationship satisfaction is stronger under an uncertain environment, while the direct and total effect of relationship flexibility on relationship satisfaction is stronger under a stable environment.
