Analysing the costs, energy use and environmental performance of an integrated steel plant by applying a multi-objective approach
(English)Manuscript (preprint) (Other academic)
Industrial decision-making is often of a multi-objective character and has become even more so in recent years as environmental issues have become more important. The aim of this paper is to analyse the relationships between different criteria by applying a multi-objective approach when optimising an integrated steel plant with a connected combined heat and power plant. Based on this analysis, the endeavour is to create a better foundation for strategic decision-making, with regard to both operation practice and investment strategy. The system is modelled with a tool that uses mixed integer linear programming, where both single and multi-objective optimisations have been performed. For the multi-objective approach, the ε-constraint method is used and the results are presented by creating pareto optimal fronts to make it easier to overview the solutions. The results show that the applied methodology is useful for facilitating the work of both determining which factors are the crucial ones for the different objectives and analysing how the objectives affect each other.
