Study On Computerized Blending-wool System Based On C/S Mode

The computerized blending-wool system based on C/S mode is studied to aim at top quality control and raw wool optimization. The system could improve top quality and make wool used in economy and reasonability. It also could make blending-wool database shared by network. The main study and innovation are as follows:The blending-wool parameters are chosen after the characteristics of raw wool are analyzed. Then the relationship between combined wool characteristics and individual wool characteristics are studied and coefficient of variation of staple length about combined wool fiber is discussed and deducted to get a formula which is validated in industrial experiment. The calculational formulae of combined wool characteristics are established.On the basis of studying relationship between combined wool and individual wool, a blending-wool mathematical model is established. The arithmetic of model is discussed and got solution through computer to optimize to blend wool. According to combined wool characteristics requirement, it could accomplish blending-wool process rapidly and obtain the optimal scheme which would not only meet combined wool requirement but also have the lowest price.Because the price of raw wool has close relation with raw wool characteristics, the formula of raw wool price prediction is established on the basis of wool price components which are analyzed from the relationship between price/discounts and raw wool characteristics. This could make individual wool economic analysis realized. A mathematical model of top reverse combined wool is established not only on the basis of relationship between top quality and combined wool characteristics but also about price component of raw wool. It could get solution through computer and calculate combined wool characteristics according to particular top qualities by the model, which produce top that meets the requirements and also have the lowest price.On the basis of study information from raw material purchase, transport, storage, production, product sale in the top mill, the information database of matching wool system is set up through programming language Delphi and database tool SQL Server 2000 for computerized blending-wool system based on C/S mode. This software include mainly eight modules as follows: raw wool input and output management, optimization of combined wool blending, optimization about top reverse combined wool, contrast between top quality prediction and actual production, data query, combined wool properties calculation, databases management, system setup. This blending-wool optimization software has been used in top mill and could be meet actual production requirement. The optimal blending-wool solution can meet actual production requirement completely and make blending-wool optimization rapidly. It has good interfaces to be simply operated and could substitute blending-wool by man which is spent long time to master. The blending-wool database could be shared by network. This is not only avail to improve and stabilize top quality but also improve production efficiency in mill.
