When designing and operating engineered systems, attention has generally been focused upon achieving stability and predictability of system operations and functions. However, in a complex coupled system, with increasing uncertainties from external drivers and perturbations, the consideration of equilibrium states is far less important than the question of persistence or survivability. We argue that resilience or its key features (e.g., functional/structural diversity and adaptability), which usually have been discussed as intrinsic characteristics of ecological or social-ecological systems, should also be embedded in industrial systems, by purposely giving operational instabilities. The idea of designing resilient and sustainable industrial system has already been proposed by several researchers by incorporating diversity, efficiency, cohesion, adaptability, and transformability [1], [2] but those are limited to qualitative approaches. Moreover, most of the discussions on resilience within engineered systems favor the adaptation of risk analysis and management [3]. Therefore, our research aims to develop a practical and quantitative ways of operationalizing resilience as originally applied in an ecological context.
