We will review some of the major results in random graphs and some of the more challenging open problems. We will cover algorithmic and structural questions. We will touch on newer models, including those related to the WWW.

There has been considerable academic interest in recent years in supply chain resilience (SCRES). This paper presents a timely review of the available literature on SCRES based on a three-stage systematic search that identified 91 articles/sources. We provide a comprehensive definition of SCRES before strategies proposed for improving resilience are identified and the contributions to the literature are critiqued, e.g. in terms of research method and use of theory. We take stock of the field and identify the most important future research directions. A wide range of strategies for improving resilience are identified, but most attention has been on increasing flexibility, creating redundancy, forming collaborative supply chain relationships and improving supply chain agility. We also find that only limited research has been conducted into choosing and implementing an appropriate set of strategies for improving SCRES. Much of the literature is conceptual, theoretical and normative; the few available empirical studies are mainly cross-sectional and confined to a large firm, developed country context; and, there has been limited use of theory frames to improve understanding. We propose Complex Adaptive Systems (CAS) theory as an appropriate lens for studying SCRES. We demonstrate that SCRES mirrors many characteristics of a CAS – including adaptation and coevolution, non-linearity, self-organisation and emergence – with implications for the direction of both future research and practice.

The role of Big Data in explaining disaster resilience in supply chains for sustainability

Purpose – This study aims to combine theory and practice to develop an integrated supply chain resilience framework by investigating the inter-dependencies between the strategic literature based concept of supply chain resilience and operational practitioner based disaster management processes. Design/methodology/approach – Utilising an in-depth qualitative case of a collaborative agency, this study identifies best practices within disaster management for insights on the operationalisation of supply chain resilience. Findings – The empirical data leads to the development of an integrated supply chain resilience framework capturing the interplay of disaster management processes and capabilities required to build supply chain resilience. The critical importance of mitigation processes in building supply chain resilience is highlighted. Practical implications – The generic supply chain resilience framework represents a valuable guide for managers when directing resources and planning for building the capabil...

Mitigation Processes – Antecedents for Building supply chain resilience

This article uses both a systematic literature search and co-citation analysis to investigate the specific research domains of organizational resilience and its strategic and operational management to understand the current state of development and future research directions. The research stream on the organizational and operational management of resilience is distant from its infancy, but it can still be considered to be in a developing phase. We found evidence that the academic literature has reached a shared consensus on the definition of resilience, foundations, and characteristics and that in recent years, the main subfield of research has been supply chain resilience. Nevertheless, the literature is still far from reaching consensus on the implementation of resilience, i.e., how to reach operational resilience and how to create and maintain resilient processes. Finally, based on the results of in-depth co-citation and literature analysis, we found seven fruitful future research directions on strategic, organizational and operational resilience.

Strategic and operational management of organizational resilience: Current state of research and future directions

With an increasing number of disasters disrupting commerce and community life around the world, it is timely to position humanitarian and disaster relief supply chains (HDRSC) within the broad field of supply chain management. This article presents a framework to that end. It distinguishes attributes of the environment that illustrate the difficulties encountered in supply chain management. Although considerable research has been conducted in logistics issues affecting HDRSCs, very little management research speaks to the complicating attributes. Thus, this article describes activities such as demand determination, supply chain coordination, recognizing when to move along the life cycle and post-disaster reconstruction that differentiates supply chain concerns from logistics concerns. From this backdrop, some of the areas where research into HDRSCs can inform supply chain management in general are presented. The article concludes by discussing critical areas of research need as identified by experienced practitioners. Research in these areas will provide insights for supply chain managers facing similar issues in other environments.

Humanitarian and Disaster Relief Supply Chains: A Matter of Life and Death

The frequency and intensity of disasters continue to increase. Following large-scale and catastrophic disasters, local organisations integrate with other responding organisations to form hastily disaster relief supply chain networks. Such supply networks are infrequently activated in a single location, generate unparalleled uncertainty, change quickly, and are driven by the urgency of saving lives and restoring livelihoods. Unfortunately, even where sound supply chain management practices are used, supply networks have encountered diverse levels of resilience and adequate disaster relief performance has remained elusive. In this paper, several unique characteristics that disaster relief efforts exhibit are examined as compared with demand-driven, steady-state supply chains. Important differences in the flows of resource, money, and information are identified. A complex adaptive supply network (CASN) lens is used to frame what existing literature has uncovered regarding disaster relief efforts, showing how...
