The invention relates to a method for determining a mechanical property (Jf) of a first rolled stock (2) by means of a hybrid model (10) comprising a production data set (Pi) of a further rolled stock (2 '), a physical production model (12) and a statistical data model (14). A first mechanical dataset, further production and metallurgical datasets (Cf, Ff, Kf) and a second mechanical dataset (Sf) are acquired from a production dataset (Pf) of the first rolled stock (2). Furthermore, an average standard distance value (df, m) with respect to the production data set (Pi) of the further rolled stock (2 ') is determined, by means of which the mechanical properties of the rolled stock (2) are determined as a weighted average of the first and second mechanical data sets (Cf, Sf). During the creation of the hybrid model (10), a further production data set (Fi) of the further rolled stock (2 ') is acquired by means of the physical production model (12) for training the statistical data model (14). 本发明涉及一种用于借助于混合模型(10
