Machine Learning for Advanced Risk Prediction
Machine learning algorithms, including Random Forest, XGBoost, and CatBoost, demonstrated exceptional performance in classifying and predicting risks within process units. Their ability to handle complex datasets and identify intricate patterns allows for more precise and robust risk assessments than traditional methods.
These models achieved near-perfect AUC scores and accuracy values, making them invaluable for proactive safety measures and preventing incidents by forecasting potential hazards with high fidelity.
Bayesian Networks and Fuzzy AHP Integration
The study highlights the power of Bayesian Networks (BN) in managing uncertainty and updating beliefs within complex risk models. BN excels at representing relationships between variables and integrating diverse data formats, from objective measurements to expert opinions.
Further enhancing this, Fuzzy Analytical Hierarchy Process (Fuzzy AHP) was utilized to quantify expert judgments, translating linguistic variables into precise probability values for the Conditional Probability Tables (CPTs) of the BN. This hybrid approach significantly improves the reliability and transparency of risk prioritization.
Enhanced Safety in Process Units
Applied to a critical chlorination unit of a combined cycle power plant, this methodology provides a structured approach to identifying and managing operational risks. The ability to dynamically assess and prioritize risks allows for targeted interventions, minimizing the potential for accidents and ensuring continuous operation.
By identifying top-priority risks like Corrosion in Electrolysis Cells and Damage and Explosion of Cells, the framework enables organizations to allocate resources effectively and implement preventative measures before incidents occur, fostering a safer industrial environment.

Real-World Impact: Chlorination Unit Risk Assessment
The study successfully applied AI and probabilistic modeling to a critical chlorination unit of a 968-megawatt combined cycle power plant. This unit, vital for producing hypochlorite for cooling operations, posed unique challenges due to chemical reactions forming sodium hypochlorite and hydrogen gas.
By integrating HAZOP with advanced ML algorithms, the team identified 160 deviations and accurately predicted risk levels. The combination of Bayesian networks and Fuzzy AHP further allowed for a robust prioritization of risks, highlighting Corrosion in Electrolysis Cells and Damage and Explosion of Cells as the top concerns.
This project demonstrates the practical applicability of AI-driven risk assessment in ensuring operational continuity and enhancing safety in high-risk industrial environments, offering a blueprint for proactive hazard mitigation.
