Cloud manufacturing model in polymer material industry
With the emergence of new materials, personalized requirements for product performance, and new application background in polymer material industry, a new manufacturing mode is supposed to be studied. Based on cloud computing (CC) and big data techniques, a specific cloud manufacturing (CMfg) mode of polymer material industry has been proposed, which is different from that of continuous industries and that of discrete industries. The critical technologies of CMfg, including forecasting and demand management, storage and transportation management, advanced process control, manufacturing execution system, enterprise resource planning, etc. have been discussed. Besides the service composition optimal selection (SCOS) algorithm for flexible manufacturing and the flexible polymer manufacturing system (FPMS) a typical product mode of CMfg is studied. Finally as a case, computer aided process planning for blending material (CAPP BM) was explored and a kind of fast searching algorithm for blending material crafts was proposed. The algorithm was applied to search target craft in more than 60,000 sections of the standard processes, production data, and environmental data, and finished its search within 10 min.
