further develop current SCI models, drawing on insights from innovation in the humanitarian supply chain The innovation in focus is the move from delivering materials in aid toward cash transfers, and how this innovation impacts on the supply chain Based on these insights, the paper suggests a refined SCI model and outlines avenues for further research in supply chain innovation Introduction Innovations are dynamic processes that focus on the creation and implementation of new... under-researched and elusive concept, especially when it comes to innovation practices in the supply chain The innovation in focus is the move from delivering materials in aid toward cash transfers, and how this innovation impacts the supply chain Based on these insights, the paper contributes a refined SCI model and subsequently outlines avenues for further research within supply chain innovation The second paper is written by Marco Antonio Viana Borges and Luciana Marques Vieira... templates for needs assessment, the use of social media for needs assessment and for matching supplies with demand, to name but a few Rather, these innovations have not been researched as to their implications for the humanitarian supply chain, and neither has research focused on supply chain innovations in this context In a seminal article on supply chain innovation (SCI), Arlbjørn et al (2011) explore the. .. Additionally, the participants had the chance to observe how the assembly of modules takes place and how the machines move through the assembly line The purpose of the visit was to provide EDSI participants the opportunity to witness the supply chain innovations taking place at the company The Papers in This Book In all, 15 papers are included in this book Based on the focus of research, these papers are divided into four parts: Part 1, Supply Chain Strategy,” Part 2, Global Distribution of... also underscored the importance of inherent risks of extended supply networks and the need for sustainability of global operations I am delighted to see a compendium of papers in this volume of the proceedings that address topics in these important areas pertaining to innovation in global supply networks The papers in this volume address a diversity of interesting topics They have been grouped into supply chain strategy, global distribution of production and sourcing, supply. .. However, this process may not be linear, but stages in the process can overlap with one another Merging these insights with the SCI model, we propose the model illustrated in Figure 1.1 for supply chain innovation Figure 1.1 Revised supply chain innovation model A first difference to the Arlbjørn et al (2011) SCI model is the stressing of “invention.” As part of the innovation process there must be willingness and the resources to invent and... grouped into supply chain strategy, global distribution of production and sourcing, supply chain integration, and sustainability The papers in the strategy section pertain to a variety of thought-provoking issues The papers in the global distribution of production and sourcing address issues relating to offshoring and insourcing The papers identify important antecedents of these two trends currently in place in a variety of industrial contexts In addition, this section includes a paper on a comprehensive literature review of... It is with great pleasure that I write this foreword of a book with papers of the 2014 Annual Conference of the European Decision Sciences Institute (EDSI) held in the beautiful city of Kolding, Denmark, under the aegis of the Department of Entrepreneurship and Relationship Management at University of Southern Denmark The meeting was organized around the theme “Exploring Innovation in Global Supply Chain Networks. ” The meeting afforded the attendees an excellent opportunity to interact... in the Offshore Wind Power Industry.” The paper explores the supply chain integration (SCI) of industries in which recurrent engineering-procurement-construction (EPC) projects are set to play an important role in the long term This empirical paper is based on interviews with key players in the offshore wind industry The findings show that information sharing and the level of collaboration are important dimensions to be studied in further stages of research regarding SCI in EPC projects... context alters the humanitarian supply chain We then revise the SCI model through this application The remainder of this article is structured as follows The literature review begins with introducing the context of humanitarian supply chains before providing an overview of SCI We then discuss, in greater detail, the five stages of innovation and the 4P model of innovation Next we propose the refined SCI model
