Competition and Cooperative Bargaining Models in Supply Chains provides an overview of the basic multi-firm models studied in supply chain management. The authors look at how the literature uses non-cooperative game theory to analyze these models and considers how some of these models can be analyzed using a cooperative bargaining framework.
This thesis addresses issues in supply chain management through cooperative and non-cooperative game theory models. It is composed of three essays. The first essay aims to understand how competition in supply chains would impact joint selling partnerships among complementary component suppliers. It models competition from two perspectives: brand competition generated from the existence of multiple partially substitutable brands (or suppliers) for a particular component, and retail competition caused by decentralization among retailers who assemble suppliers' components into final products and sell them to customers. The second essay studies how the durability of the end product and the purchasing behavior of end consumers, in terms of consumer's forward looking behavior and patience, affect the alliance decisions of complementary firms. It also comments on how results are affected by scenarios like manufacturers directly selling to the end consumers or them having multiple alliance formation opportunities. The third essay employs a bargaining framework to investigate a manufacturer's preference over its retailers' market composition within a supply chain. In addition, it also aims to understand how such business relationships are influenced by the bargaining approach, dominant retailer and competition from other supply chains providing similar competitive products.
In this book methods from Operations Research and Game Theory are used to determine companies’ profit-maximizing strategies related to pricing and (cooperative) advertising. It considers different supply chain structures as well as various distributions of power, making it possible to analyze both inter-echelon and intra-echelon dependencies between the companies’ decisions. Additionally, an approach based on fuzzy set theory is presented in order to compensate for incomplete or missing data on market characteristics. Vertical cooperative advertising is an essential element of partnerships between manufacturers and retailers, allowing manufacturers to financially support their retailers’ advertising efforts so as to increase sales for the entire supply chain. Given that such programs not only make up a considerable part of many companies’ advertising budgets, but are also a controversial subject in many business relations, their correct design is of particular importance.
This paper surveys some applications of cooperative game theory to supply chain management. Special emphasis is placed on two important aspects of cooperative games: profit allocation and stability. The paper first describes the construction of the set of feasible outcomes in commonly seen supply chain models, and then uses cooperative bargaining models to find allocations of the profit pie between supply chain partners. In doing so, several models are analyzed and surveyed, and include suppliers selling to competing retailers, and assemblers negotiating with component manufacturers selling complementary components. The second part of the paper discusses the issue of coalition formation among supply chain partners. An exhaustive survey of commonly used stability concepts is presented. Further, new ideas such as farsightedness among supply chain players are also discussed and analyzed. The paper also opens some avenues of future research in applying cooperative game theory to supply chain management.
In light ofthe vast number ofpublications on Supply Chain Management (SCM) it is not easy to extract those which will have a great impact both on theory and practice. The dissertation of Gregor Dudek certainly is one such valuable source because it tackles inter-organizational collaboration in a novel and effective man ner. SCM is concemed with the coordination of material, information and financial flows within and across often legally separated organizational units. lt has gained great attention both in industry and research as an important area for improving competitiveness. A Supply Chain (SC) can be regarded as a hybrid between a market relationship and a hierarchical organization and as such requires specific tools to support the efficient planning and execution of the order fulfillment proc ess. Software vendors have developed so called Advanced Planning Systems (APS) to overcome deficiencies of traditional Enterprise Resource Planning systems and to better support the planning functions needed in SCM. However, APS are based on the principles of hierarchical planning which are well-suited for intra organizational SCs but fall short when non-hierarchical collaboration between partners (companies) is needed. This is particularly true when a buyer and a sup plier have to align their medium term order and supply plans.
The consensus among academic researchers is that supply chain management lacks grounding theory specific to its field and arguably enough to be recognized as an academic discipline. This paper uses game theoretic, asymmetric Nash bargaining to develop a new theory specific to operations and supply chain management. Supply chain bargaining theory connects supply chain management practices to a firm's financial performance. The theory quantifies a relationship explaining that a firm increases profit by improving its competitive advantage among its competitors and bargaining power with its customers. The concept of competitive advantage links to existing literature that focuses on a firm's internal capabilities and those provided by their upstream supply chain. Bargaining power provides a conceptual connection to a firm's downstream customer management practices. The concepts and relationships of this new theory align with existing conceptual and empirical supply chain management and operations research. Supply chain bargaining theory clarifies the binding mechanism between dyad members of supply chains which can facilitate future research into supply networks.
Traditionally supply chain management has meant factories, assembly lines, warehouses, transportation vehicles, and time sheets. Modern supply chain management is a highly complex, multidimensional problem set with virtually endless number of variables for optimization. An Internet enabled supply chain may have just-in-time delivery, precise inventory visibility, and up-to-the-minute distribution-tracking capabilities. Technology advances have enabled supply chains to become strategic weapons that can help avoid disasters, lower costs, and make money. From internal enterprise processes to external business transactions with suppliers, transporters, channels and end-users marks the wide range of challenges researchers have to handle. The aim of this book is at revealing and illustrating this diversity in terms of scientific and theoretical fundamentals, prevailing concepts as well as current practical applications.
Many organizations find supply chain management an essential prerequisite to building a sustainable competitive edge for their services or products. While interest in SCM is enormous, lack of theoretical frameworks and real world applications often characterizes research in the field, and effective management of the supply chain remains elusive. Supply Chain Sustainability and Raw Material Management: Concepts and Processes is a comprehensive and up-to-date resource for operations researchers, management scientists, industrial engineers, and other business practitioners and specialists looking for systemic and advanced discussions of supply chain management. By presenting qualitative concepts, quantitative models, and case studies, this book is a coherent guide to creating long-term and sustainable performance for organizations who want to compete in the global market.
This book lays the foundations for quality modeling and analysis in the context of supply chains through a synthesis of the economics, operations management, as well as operations research/management science literature on quality. The reality of today's supply chain networks, given their global reach from sourcing locations to points of demand, is further challenged by such issues as the growth in outsourcing as well as the information asymmetry associated with what producers know about the quality of their products and what consumers know. Although much of the related literature has focused on the micro aspects of supply chain networks, considering two or three decision-makers, it is essential to capture the scale of supply chain networks in a holistic manner that occurs in practice in order to be able to evaluate and analyze the competition and the impacts on supply chain quality in a quantifiable manner. This volume provides an overview of the fundamental methodologies utilized in this book, including optimization theory, game theory, variational inequality theory, and projected dynamical systems theory. It then focuses on major issues in today's supply chains with respect to quality, beginning with information asymmetry, followed by product differentiation and branding, the outsourcing of production, from components to final products, to quality in freight service provision. The book is filled with numerous real-life examples in order to emphasize the generality and pragmatism of the models and tools. The novelty of the framework lies in a network economics perspective through which the authors identify the underlying network structure of the various supply chains, coupled with the behavior of the decision-makers, ranging from suppliers and manufacturers to freight service providers. What is meant by quality is rigorously defined and quantified. The authors explore the underlying dynamics associated with the competitive processes along with the equilibrium solutions. As appropriate, the supply chain decision-makers compete in terms of quantity and quality, or in price and quality. The relevance of the various models that are developed to specific industrial sectors, including pharmaceuticals and high technology products, is clearly made. Qualitative analyses are provided, along with effective, and, easy to implement, computational procedures. Finally, the impacts of policy interventions, in the form of minimum quality standards, and their ramifications, in terms of product prices, quality levels, as well as profits are explored. The book is filled with many network figures, graphs, and tables with data.
