Chalco Henan Branch Alumina Production Operations Mis Research,

The aluminum production operations of Aluminum Corporation of China Henan Branch began in 1991. The system was developed in DOS environment, and C language was used to develop the system. As the company continues to expand production scale. At the same time, Production engineering and production technology constantly changed. Existing legacy systems can not meet the demand for alumina production operations management of Aluminum Corporation of China Henan Branch.The company is eager to re-development alumina Production Operations Management System in Windows environment.I have detailed knowledge of the company's alumina production operations management business, using a structured system development method, through stages including systems analysis, design, detailed design, programming and testing. In the Windows environment using C++language developed in aluminum production operations management information system. The content of the system are as following, goods AO basis,chattels AO basis, the alkali consumption calculation, the main raw material fuel income consumption deposit basis, finished goods and products produced consumption deposit calculation, step scales, major equipment operation rate and the productivity calculation, Products and major product yield calculation, the main technical completion of calculation of economic indicators, quality and completion of major consumption quota calculation and so on.In addition, based on the user request, I have used historical data and data mining technology, the seven indicators of the quality of alumina were studied. And identified quantitative relationship between the quality of alumina and seven indicators. Through the user confirmation and user verify, Finally, quality control module of alumina was increased in the system with seven indicators. And quality control of alumina was achieved.The system has been put into use. The system operating normally.The user was satisfied.
