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
- 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.
