In this paper a simulation approach based on flowsheeting process models is presented and used for the assessment of cleaner technologies. The use of flowsheeting systems to support decisions on strategic, tactical and operative planning level, tackling a variety of problems occurring in the metal industry, are sketched.Text/Conference Paper
