This study investigates the integration of machine learning (ML) with quantitative risk assessment (QRA) as tools to optimize RO processes in pharmaceutical purified water systems. The main objectives of this study were to apply a multivariable mathematical model, integrate QRA with ML techniques, and validate the predictive models with QRA outputs. The study followed a systematic methodology to achieve its objectives. Firstly, critical process parameters (CPP) were identified using the multivariable mathematical model, followed by data simulation with @RISK software. The Friday 13th (Fr 13) framework was implemented using Monte Carlo simulations to identify unexpected failures. 10,000 iterations were generated from @RISK to evaluate the distribution of risk factors. The data was then imported into RapidMiner for ML analysis to create predictive models. The ML approach used Random Forest ML algorithms to improve risk prediction and classification. The dataset was split into training (70%) and testing (30%) subsets to ensure robust model validation. The analysis, which included 10,000 data points and represents 100% of the dataset, showed a failure rate of 20.8% for @RISK and 20.82% for RapidMiner. The results showed a slight difference (0.02%) in the risk of failure, demonstrating it accuracy of the predictive models. The integration of ML improved predictive accuracy, with the Random Forest model identifying risk factors with a high classification performance (97.8%). These results demonstrate the accuracy of the developed machine learning model and its potential for accurate risk assessment in RO systems. To conclude, the integration of ML and QRA provides a reliable and efficient approach to risk assessment in pharmaceutical RO systems. These results highlight the potential of ML to automate risk analysis and optimize operational performance UR - https://umpir.ump.edu.my/id/eprint/47706 ER -
