1.1 Introduction
An expert system is a software system that attempts to reproduce the performance of one or more human experts, most commonly in a specific problem domain, and is a traditional application and/or subfield of artificial intelligence. Expert system play an indomitable role in various disciplines and the assistance it renders to man cannot be overemphasized. The development of experts system that capture skills and expertise of a human expert has not been easy and date back to the Second World War, where experts of computer tried relentlessly to develop technique or systems that would allow act more intelligently than human. A computer is digital electronic machine capable of accepting input data, processing and producing an output. The computer is an important tool that plays a good role in the analysis of any subject that is to be programmed. A quality control and monitoring system in production management is a qualitative technique with strong financial implications having direct relationships with production, marketing and purchasing.
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study.
