METHOD AND ELECTRONIC DEVICE FOR CONTROLLING A MANUFACTURING OF A GROUP OF FINAL METAL PRODUCT(S) FROM A GROUP OF INTERMEDIATE METAL PRODUCT(S), RELATED COMPUTER PROGRAM, MANUFACTURING METHOD AND INSTALLATION

Abstract:

A method for controlling a manufacturing of final metal product(s) from intermediate metal product(s) is implemented by an electronic controlling device and comprises, for each intermediate metal product acquiring (110) a set of intermediate characteristic(s) (C.sub.IP) for said intermediate metal product; determining (120) a current estimated set of final characteristic(s) (C.sub.est_cur) with a prediction model, according to the set of intermediate characteristic(s) and a current manufacturing route; comparing (130) the current estimated set of final characteristic(s) with a current target set of final characteristic(s) (C.sub.target_cur); and if a deviation between the current estimated set of final characteristic(s) and target set of final characteristic(s) is above a threshold obtaining (140) new target set(s) of final characteristic(s) (C.sub.target_new) for new final metal product(s); and calculating (150) a new manufacturing route according to the set of intermediate characteristic(s) and to the new target set(s) of final characteristic(s).
