The invention is concerned with a computer-implemented method to produce a model that predicts the performance of a ship. The method comprises the steps of creating an initial model for simulating the performance of the ship by means of relationships between factors related to the ship during operation and parameters presenting primary dynamic input data that depend said factors depend on. Measurement results are obtained from sensors during the operation of the ship for producing a set of new dynamic input data to be used in the model. A simulation result for the ship performance is calculated by using said produced input data in said model instead of the primary dynamic input data. The simulation result is then compared to the actual ship operation. If the difference between the simulation result and the actual operation exceeds defined threshold criteria, the model is improved by repeatedly producing new sets of dynamic input data to be used in the model by means of new measurement results until defined quality criteria are met. The invention is also concerned with a system that performs such a method and a computer program.
