Microsoft Word - 05 expert system

ABSTRACT To meet the challenges of international competition a rolling mill must be able to produce high quality products cost effectively. The optimization of production and product quality is possible when the effect of each process parameter on process performance and the product properties is known. Presently, the process control parameters are based mainly on mathematical and statistical models changing product properties or process parameters, or the introduction of a new steel grade may, however, require tedious recalculations or even experimental tests that are both expensive and time-consuming. By using neural, artificial intelligence, fuzzy control most of computing and related work can be avoided. There are also many process steps for which exact mathematical models do not exist, and the process is affected by the human behavior of the operator. This research is focused on developing a new system that combines an expert system with rolling process. The web based expert system for rolling operation is implemented in a novel way. The World Wide Web is used as the platform for the online rolling operation and it offers several advantages to the conventional stand-alone approach. The result presented in this research paper can thus be used as basic to provide solution for practical usage
