Shearing optimization of the rolled billet according to a minimum waste criterion

The purpose of this paper is to resolve the control problem of shearing a rolled billet. The appropriate control should result in shearing each section to a length which consists of a predetermined basic length and a tolerance. The control should be effected with the minimum waste criterion. Because the final length of the rolled billet to be cut is not known, the control is based on the prediction of this length. The prediction procedure as well as the static and dynamic process optimization is given in the paper.
