Abstract: Aiming at controlling the cost of raw material and raising the quality of top processing, the information concerning the key processes of top processing such as raw material purchase, transport, storage, production, and marketing of the mill was investigated, and a computerized wool blending and information management system based on C/S mode was developed. This paper introduced the overall structure of the system, functions and goals, database establishment and software design. The practical application of the sysem in the top mill proved that it could meet the production requirements completely. It made the wool blend rapidly, enhanced and stablized the product quality, and realized common share of the data on wool blending, facilicating the improvement of production efficiency and information management level.
