Supply chain resiliency: A review

Abstract

This chapter provides a broad overview of the field of supply chain resiliency. First, we define the concept of resiliency from the perspective of a supply chain. Next the terms risk and vulnerability are defined in the context of a resilient supply chain. This connects previous studies in supply chain engineering to the emerging field of resiliency. The second section of the chapter outlines components that contribute to the resiliency of a supply chain. Supply chain flexibility, velocity, visibility, and collaboration are defined and references to additional sources are provided. The third section of the chapter outlines processes that are used for building resilient supply chains. A number of relationships between supply chain risk and profitability are explored, along with their impact on supply chain resiliency. This section further provides a unifying exploration of the various aspects and perspectives on supply chain engineering, including how they can be utilized for developing and measuring the resiliency of a supply chain. The chapter concludes with remarks ongoing research on supply resiliency and identifies knowledge gaps and topics for future research.
