Brief Abstract:

There may come scenarios where system components fail to adhere to certain predefined thresholds and cross a breaking point. It is therefore proposed in this study that systems can be survivable, instead of resilient, when they comply in time with the resurgence property. This property signifies the systematic behavior of overcoming a certain stagnation period and, after a time range, return as a transformed system with new functions and challenges. Through this study, it was detected that the symmetries between resilience and survivability are only superficial if systems suffer breakages after misconceiving the factual causes of failure. To discover these causes, this proposal presents a Markov-based approach that integrates technological, social, and economic aspects that describe a holistic industrial system (HIS) under disturbance. These systems replicate the complex behavior of different sectors in a society and private enterprises alike. The model incorporates resilience and survivability measures and the concepts of breaking points (referred to as divergence) and resurgence. The representation of a HIS intends to be more extensive than other models as it evaluates systems at different performance levels and state spaces through time. The model is meant to be a tool to forecast or anticipate breaking points and resurgence events through a HIS’s lifecycle. It is also designed as a mathematical foundation for system simulations in the future. To prove the legitimacy of the approach, the most recent predicaments of a U.S. territory have been transcribed to the mathematical dialect of a HIS under stress with real historical data and socioeconomic and technological innovation indicators. To further expand on the assessment toolkit, it is proposed to design a simulation model that would allow for level adjustments on the three sustainability aspects of a HIS. Through it, possible strength-strain ranges are meant to be discovered at the end of the study.
