These data sets include plant operating parameters and laboratory measurements for feed properties.

Furthermore, this predictive machine learning model is incorporated into a linear optimization framework to enhance crude oil purchasing decisions for a downstream refinery. Results suggest that the proposed approach, combining predictive and prescriptive analytics, can result in significant profitability gains estimated at $730,000 annually.
