Assessment of Community Resilience with Complex Network Perspective
Presenter: Junqing Tang (Eidgenössische Technische Hochschule Zürich (ETHZ), Singapore)
Co-Authors: Hans Rudolf Heinimann  
Introduction: Community resilience of different scenarios and performance can hardly be effectively assessed and improved, and most existing studies address the community resilience in conceptual, macroscopic and statical ways. Therefore, an emerging method and an approach that can assess microscopic resilience in a complex network is in need.
Methods: We proposed a performance-based generic metric and novelly established a "drawdowns-drawups" analytical method to quantify resilience at microscopic level. By bolting on six elemental functions: robustness range, elasticity threshold, recovery scenario, recovery magnitude, recovery time and resistance effort, it provides a significant illustration of performance adaptability. In modelling section, we conducted a pilot study and constructed a proxy network model to simulate possible individual relationship in community. The proxy model was constructed based on large historical data of companies listed in London Stock Exchange. Time-series performance data of companies were analysed and the community evolutionary and clustering pattern were visualised.
Findings: (a) The new method is effective for resilience assessment, and the metric helps to understand the resilience complexity. (b) The dynamic resilience indices have a certain power-law-distributed feature. It may implicate the resilience complexity could be revealed by simple mathematical distributions. (c) Community network has "fusion-fission" resilient behaviour.
