Abstract
In this study, a part of a complete Expert System (ES) for powder technology is presented. 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.
Highlights
One important industry witnessing an increasing importance and vast development in the production as well as the processing of tremendous products of ever increasing new material is powder technology
An expert system for the best selection of powder and production method according to desired properties and characteristics for a certain application is successfully developed
The inference engine, EXSYS-CORVID is used as development tool for this system
Summary
One important industry witnessing an increasing importance and vast development in the production as well as the processing of tremendous products of ever increasing new material is powder technology. The work presented in this study is concentrated on the first area mentioned above, with particular emphasis on the loose powder materials and the powder production process selections for certain application. The practical definition for the expert system, as a system simulating the expert methods and knowledge in dealing with or manipulating special tasks is presented The application of such system in powder technology is attempted. A functional prototype expert system was developed using a rule-based knowledge representation model This system, which is structured on intelligent technology and engineering knowledge is believed to be the backbone of the suggested Computer Integrated Manufacture for Powder Technology (CIMPT).
