PRAF: Process Resilience Analysis Framework for Design and Operations

Process plants are complex socio-technical systems that degrade gradually and change with advancing technology. This research deals with exploring and answering questions related to the uncertainties involved in the process units, and their complexity. It aims to systematically integrate resilience in process design and operations through three different phases of avoidance, survival, and recovery. This analysis relies on data-driven model and optimization approach utilizing the resilience metrics developed in this research. These metrics integrate both technical (e.g., process parameters variations, equipment failure) and social (e.g., human and organizational) factors. In particular, an integrated method incorporating process, maintenance, safety, and cost is developed to:

- predict process upset events using deep learning, global sensitivity analysis, and robust simulation approaches,

- assess cumulative risks and develop policies for safety barriers during a process upset situations using Bayesian analysis, regression, modeling, and optimization, and

- reduce response time using modeling, Bayesian analysis and optimization.

This seminar highlights the application of this proposed framework for the avoidance and survival phases. Detailed example problems on a batch reactor and cooling tower operations are used to illustrate the potential of the proposed framework.

The results indicate that the framework is successful in capturing the interactions between the process operability characteristics, social aspects, safety, and maintenance policy. This leads to a< reduction in uncertainty and helps in improved and more informed decision-making.
