This dissertation studies the impact of different network structures and the structural positions of supply chain entities on their performance. The first essay focuses on the performance of buyers by examining the relationship between buyers' supply network structures and their performance. We use two network-level measures (network density and network centralization) as indicators of different supply network structures to study this relationship. We investigate how the interplay between network structure and firm performance differs in various industry settings. Our ego-centric network panel dataset from 2015 to 2018 included focal companies from three industries: automotive (n = 76), pharmaceutical (n = 66), and food & beverage (n = 105). Our results suggest that supply network structures have differential effects on buyer performance contingent upon industry context. We provide specific recommendations to focal companies' managers on what specific network structures would enhance their operational performance under various business environments.The second essay investigates what specific aspects of first-tier suppliers drive their performance. We consider two multi-factor efficiency measures: operational efficiency and structural efficiency. We investigate the direct effects of structural and operational efficiencies on first-tier supplier performance as well as the moderating role of structural efficiency in the relationship between operational efficiency and supplier performance. We test these relationships using a panel dataset of 278 observations obtained from 75 first-tier suppliers in the global automotive supply network over four years. Our findings demonstrate synergies between suppliers' internal resources and external relationships in enhancing their performance.Building on the first two essays, the third essay investigates the supply network structures that are robust to disruptions from the focal company's standpoint. By considering network density and network centralization, and modeling supply chain disruptions using simulations, we assess the impact of disruptions by investigating changes in the structural efficiency of the focal company. Our findings suggest that dense and decentralized supply networks are more robust to disruptions than sparse and centralized supply networks. We also find that this result becomes more evident as the magnitude of the disruption increases. Our findings have important implications for resource allocation and fortification strategies to design and operate robust and resilient networks.

Micha Hirschinger emphasizes the importance of foresight on logistics and institutions in particular for effective decision making as distinct research in this context is limited. He applies a systematic and transferable multi-method approach based on Delphi studies and fuzzy c-means cluster analysis to develop profound scenarios for the future. He uses the relevance of information-processing requirements to investigate whether centralization of purchasing organizations increases functional efficiency. The author finally shows how a sharing-economy business model transfer could help to overcome the limited access to factor markets, especially trucks, at the base of the pyramid.

This thesis focuses on the interface of project and supply Chain Management. Supply chain decisions (e.g., material planning, network design, supply management) and project management decisions (e.g., resource planning, expediting, and project scheduling) are intertwined in many firms. The objective of this thesis is to construct and analyze new models and methods that can help firms integrate supply chain and project management. Specifically, we addressed the following issues: (1) Joint optimization of inventory and project planning decisions for recurrent projects subject to random material delays (Chapter 2), often found in construction industries. (2) Designing and managing the development chain for one-of-a-kind R & D projects with an extensive workload outsourced (Chapters 3,4), representing the recent trend in the aerospace and defense industries. In Chapter 2, we study a new class of problems -- recurrent projects with random material delays, at the interface between project and supply chain management. Recurrent projects are those similar in schedule and material requirements. We present the model of project-driven supply chain (PDSC) to jointly optimize the safety-stock decisions in material supply chains and the crashing decisions in projects. We prove certain convexity properties which allow us to characterize the optimal crashing policy. We study the interaction between supply chain inventory decisions and project crashing decisions, and demonstrate the impact of the PDSC model using examples based on real-world practice. In Chapter 3, we study incentive and coordination issues in development chains. Collaboration and partnership are the way of life for large complex projects in many industries. While they offer irresistible benefits in market expansion, technological innovation, and cost reduction, they also present a significant challenge in incentives and coordination of the project supply chains. In this chapter, we study strategic behaviors of firms under the popular loss-sharing partnership in joint projects by a novel model that applies the economic theory of teamwork to project management specifics. We provide insights into the impact of collaboration on the project performance. For a general project network with both parallel and sequential tasks where each firm faces a time-cost trade-off, we find an inherent conflict of interests between individual firms and the project. Depending on the cost and network structure, we made a few surprising discoveries, such as, the Prisoners' Dilemma, the Supplier's Dilemma, and the Coauthors' Dilemma; these dilemmas reveal scenarios in which individual firms are motivated to take actions against the best interests of the project and exactly how collaboration can hurt. As remedy, we enhance collaboration by a set of new provisions into a ``fair sharing" partnership and prove its effectiveness in aligning individual firms' interests with that of the project. In Chapter 4, we extend the model in Chapter 3 in two directions. First, we extend the discrete-time model to a continuous-time model and show that the Coauthor's Dilemma still holds and thus the project will never be finished earlier under the loss-sharing partnership than the centralized control system. Second, we consider stochastic task durations and find that the uncertainty increases the probability of project delay.

In the fall of 1992 a conference honoring Elwood S. Buffa was held at the Anderson Graduate School of Management of the University of California, Los Angeles. This book is a collection of the work presented at that conference. The scholars who gathered to honor El are the prominent researchers in the field of Operations Management. Their collective work published in this book represents the richness of the field and provides the reader with valuable insights into its important issues and problems. While any grouping of the articles by these distinguished scholars will be arbitrary, I have organized the book in four sections. In the first section the articles dealing with the strategic issues in Operations Management are compiled. The articles deal with continuous improvement, quality, services, supply chain management, and creating value through operations. The articles that explore the interface of Operations Management with other functional areas, e.g. engineering and marketing, are grouped in the second section. The third section of the book contains articles that attempt to model some important planning problems that arise in the management of production and operations. Some of the papers in this section provide state of the art reviews of selected topic areas. Finally, the fourth section contains articles that deal with future directions for Operations Management. The authors offer several insights into the future evolution of the field. The book begins with the keynote address given by El Buffa at the start of the conference on November 2, 1991.

With her work, Irène Kilubi builds a bridge between two areas of business research, on the one hand the supply chain management, and on the other hand innovation and technology management. In the context of her work, she proposes to expand the usual instruments of supply chain risk management by strategic technology partnerships, which not only provide procurement alternatives but also the possibility to develop technological alternatives at short notice. More precisely, she advocates that the capabilities needed for STP serve as enablers for effective SCRM. Accordingly, connections between supply chain risk management and strategic technology partnering are presented and a conceptual framework is correspondingly created.

This dissertation consists of four essays that contribute in the investigation of the interface between marketing and operations in supply chain management (SCM). The main motivation behind this work relate to the evolution of SCM, which goes from a mere logistics function expanded across inter-organizational boudaries to a systematic coordination and integration of traditional business functions. This evolution pushes researchers and practitioners to think about SCM as a sophisticated and complex phenomenon that needs to be further explored. This dissertation provides four essays and each of them carries out specific motivations and addresses price issues. The first essay empirically investigates which business function, between marketing and operations, contributes the most to firm's corporate performance in SCM. On the other hand, the research provides prescriptive insights to managers on how to boost the effectiveness of SCM on corporate performance when focusing either on operations or on marketing activities while adopting specific managerial levers. The second essay draws a detailed map identifying the current research gaps to be eventually filled. It elaborates information from 108 papers published over the last thirty years and provides the ongoing research directions to be undertaken by future studies investigating the interface between marketing and operations in SCM. The third essay introduces a differential game of marketing and operations modeling both vertical coordination and horizontal SC competition. It highlights the interfaces between marketing and operational strategies in a context of symmetric competition. The main result concerns the effect of coordination on competition. When the SCs are not coordinated, competition is played only by price. Conversely, When the SCs are coordinated, competition is played on both pricing and advertising. Coordination intensifies SC competition and turns out to be economically ineffective. The last essay shows the advantages of integrating marketing and operational strategies in an atypical supply chain(e.g., closed-loop supplay chain) where economic, environmental and social issues occur simultaneously. The main result concerns the effectiveness of coordination and the additional knowledge supplied when having dynamic returns to better understand the interfaces between marketing and operations. Summarizing, this dissertation shows the evaluable research findings obtainable when a complex phenomenon like SCM is analyzed from different persepctives, such as marketing and operations. Future research in the domain of SCM should pay more attention to the interfaces and the integration between business function's strategies to provide realible, complete and prescriptive managerial insights and research findings.
