Abstract

The study demonstrated the application of partial least square regression technique in the development of a monitoring strategy for a process industry. The process industry under consideration is an integrated steel plant engaged in the production of steel billets. The steel making shop which has been the focus of the study is a complex process replete with numerous and inter-related process, feedstock and quality characteristics. The main challenge addressed in this paper is the development of a monitoring strategy for the concerned steel making shop taking into account all the characteristics (process, feedstock and quality) simultaneously. The strategy thus devised seems to bode well, as it was correctly able to ascertain the status (in state of statistical control or out-of-control) of the process. Further capability studies via the employment of a multivariate process capability index were carried out to determine the efficacy of the process in producing end products. The capability study highlighted the fact that the process needs readjustment as a substantial amount of end products produced were out of specifications.
