  16. 16. AI study Demand and price forecasting Challenge Feedstock and product prices and product demands are increasingly volatile. Optimization of the value chain with poor price and demand forecasts is sub optimal.
  17. 17. Solution Use ML algorithms to forecast demand. High performance computing and AI we can optimize and compare multiple scenarios to reduce risk. Find the predictive model that leads to the minimal prediction error such as a neural network (e.g. MONMLP). Provide the model predictions to the planners to improve multi- period optimisation. Predicted Actual
  18. 18. AI study Automation of LP & Scheduling Model Updates from Rigorous Model Challenge For speed, Planning and Scheduling Models are simplified (often linear) from rigorous models. Linear models result in artificial constraints and are not able to see all opportunities. Maintaining the rigorous models and recalibrating to actual plant performance takes time and expertise.
  19. 19. Solution Benefits An ML surrogate model that improves the linear models can be generated. This can be done by using synthetic data from the Rigorous Model to train the ML model. Use past model performance and current model deviations and an AI Classifier to find the pattern of deviations that characterize a poor model and trigger and update of the relevant part of the model. Decrease Model Update Times due to better definition of Improvements areas Reduced need for SME participation ML Planning/Scheduling Model that accounts For a larger range of Operating conditions Maximize Model Accuracy by Better Definition Of Re-calibration Needs
