Resilience to Supply Disruptions in a Non-Linear Two-Tier Supply Chain Model

Background

A resilient enterprise may be able to minimize the disruption and hence the amount of the required recovery. This elasticity is reflected in definitions of resilience for example:

Two comprehensive reviews of the literature of SC resilience have been made by Hohenstein, et al. (2015) and Kamalahmadi and Parast (2016). Hohenstein et al. (2015) divided the reviewed papers into 4 main groups based on the concern with Readiness; Response; Recovery and Growth. They found the most important factor to emerge was that of SC flexibility and they report intra and inter SC collaboration high on the list of important objectives. They suggest using theoretical models to check the effectiveness of proposed solutions. Both groups of reviewers provide definitions of resilience that encompass that mentioned above. Kamalahmadi and Parast (2016) grouped publications into those concerned with network flexibility and those concerned with redundancy in the network, suggesting further research into how these concepts can be put into practice and the effects then measured. A systems view of what has been proposed is shown in Figure 1.
