Optimum Scheduling of a Hot Rolling Process by Nonlinear Programming

Adaptation for tandem cold mill models

“…Among the various existing optimization methods, some recent applications related to cold mill set-up optimization include nonlinear programming (Ozsoy et al, 1992), genetic algorithms (Wang et al, 2000), and more specifically the (Nelder and Mead, 1965) simplex method, which was employed in Fiebig and Zander (1982) and also by Cosipa cold mill automation system (Pires et al, 2006). A detailed description of the simplex method can be found in Walters et al (1991).…”

Set-up optimization for tandem cold mills: A case study

“…Among the various existing function minimization methods, some recent applications related to cold mill set-up optimization include nonlinear programming [3], genetic algorithms [5], and more specifically the Nelder and Mead simplex method [7], which was employed in Ref. [2] and also by Cosipa cold mill automation system.…”

“…The importance of such optimization first appeared in Ref. [1] and it has been object of several recent works [2][3][4][5].…”

Global Method for a Class of Operation Optimization Problem in Steel Rolling Systems

“…The objective was to minimize the deviation of the rolling crown from a set target. Ozsoy introduced a sequence quadratic programming method to solve the load distribution problem in a hot-rolling line so as to minimize cost of time and energy. Yao et al proposed an improved differential evolution algorithm for a three-stage multiobjective OOP in hot strip rolling.…”
