It deals with the powder selection according to predetermined recommended or required material properties and specific powder characteristics.This leads to the determination of the most common powder production (i.e., processing) method, which satisfies the specified powder requirements for a specific application.
For this purpose a detailed functional prototype expert system is developed using a rule-based knowledge representation model. The expert system is designed to acquire knowledge from the user then give recommendations. The inference engine, EXSYS-CORVID, is used as the development tool. The forward and backward chain technique is utilized, thus the reverse process is also be possible. Therefore, the system will determine or assign some primary powder characteristics and production method to satisfy or achieve the required product and vice versa. The developed expert system is flexible, easy to be implemented, modified and extended. The system displayed excellent performance and typical illustrative examples are shown. The proposed system is believed to assess in increasing productivity in the field of powder technology and increases the profitability and competitiveness of the process in a modern ever increasing industries.

Keywords: Expert system, E XSYS-CORVID, powder selec tion, powder technology INTRODUCTION One important industry witnessing an increasing importance a nd vast development in the pro duction as well as th e pro cessing of tremendous products o f ever increasing new material is powder technology. In this industry, the main objective is to produce sound compacted components of homogeneous uniform density with predetermined properties. This, however, depends on controlling a huge number of interdependent parameters at the various stages of the process.
