Computerized relational model for powder technology: powder and process selection

Part of a complete expert-system software design for powder technology is p resented. This part of the system deals with powder selection according to predetermined, recommended or required material properties, and specific po wder characteristics. Then the optimum powder production, i.e processing, m ethod is determined, which satisfies the requirements of the specified powd er. For this purpose a detailed database relational model is developed, and the system's software modules are described. A relational model is formula ted and a structured query language (SQL) is used in the detailed software design presented.
