Chemical process modeling

A computer-implemented method for providing a model for monitoring and/or controlling an industrial plant, said industrial plant comprising a plurality of equipment, wherein the method comprises:

• providing a plant level model of the industrial plant;
• wherein the plant level model has been generated via a topology generator by selecting and interconnecting equipment models from a model library, the model library comprising computer readable equipment models for at least some of the equipment, and the plant level model being a topology representation of the industrial plant,
• obtaining, using a model trainer, a trained plant level model;
• wherein the trained plant level model is obtained from the plant level model by training at least some of the equipment models in the plant level model using one or more historical datasets;
• wherein the trained plant level model is usable for computing at least one performance parameter via a model executor, the at least one performance parameter being related to the industrial plant.
