Abstract
expert system is a computer program that functions in the same manner as a human id advising the user on how to solve a problem. The main objective of this thesis is to e possibility of using and applying Expert System Techniques to control chemical specifications. This has been done through the design and implementation of a rule-expert system for controlling PVC specifications, which simulates human expertise. inyl Chloride (PVC-Resin K67) is adopted as a case study in order to illustrate the and the benefits of the proposed expert system prototype.
; This thesis is organized into six chapters. Chapter 1 is ” Introduction ”, in which the
of TVC specifications is introduced and the reasons why we need an expert system •
jlling PVC specifications are presented.
Chapter 2 is ” Literature Survey ”, and it is divided into two sections (2.1 and 2.2). 2.1 is ” PVC Suspension Polymerization ”, in which a literature survey of rization reaction, suspension PVC production and the influencing factors on its tions are presented, then the basic problems involved in how to control PVC itions in a simple manner are illustrated. Section 2.2 is ” Expert Systems ”, in which survey of expert systems and knowledge representation are presented. Expert development tools are also investigated with a special emphasis on rule-based lent techniques and environments.
Chapter 3 presents an ” Anatomy of the Prototype Implementation ”, in which the rule-expert system for controlling PVC specifications is presented. The structure of the
