Using an MBSE approach for automation control system selection in long steel products hot rolling plants

Abstract: Automation systems in long steel products hot rolling plants are prone to performance failures with the potential of serious negative impact on the business. The selection process of these automation systems therefore requires careful consideration of various selection factors to maximize plant performance. The need was therefore identified to investigate the use of a suitable management approach to guide engineering automation teams in the long steel products hot rolling plants in the selection of automation systems. At the core is the need for an in-depth understanding of the issues surrounding distributed and hierarchical automation systems in long steel products plants. This includes identifying the challenges during the selection process, using sound engineering management principles. Current automation selection techniques were investigated through a survey, interviews and a case study. It was then decided to use a Model Based Systems Engineering (MBSE) approach, which utilises systems engineering principles together with digital technology to create models to simplify the understanding of complex problems and relationships. This was then used to develop a management framework for automation systems selection in support of the business case of long steel products hot rolling plants
