This paper addresses the problem of modernizing the Egyptian Iron and Steel factory at Helwan, using process computer Control. The problem of priorities within different sections of the factory to first apply the process computer control is encountered. It is shown that, for the Helwan factory, computerization procedure should commence first in the Oxygen Steel Converter Shop, then followed by the Hot Rolling Mill process. For the steel converter shop, statistical data analysis are carried out as a pre-requisite for developing the necessary mathematical model for the on-line computer control application. It is demonstrated that, with the random trend appearing in the steel making data, statistical components in modeling are mandatory. Finally, the future steps to be followed for model building, economical justification of computerization and real life model implementation are elucidated.
