Statistical Process Control Based On Data Mining Research Projects

Statistical Process control (SPC) is an advanced technology of quality management and control based on mathematieal statisties, it mainly aims at Proeess stability, concerns Prevention of whole Proeess. SPC is able to reduce wasters effectively, cut cost of Production consequently.At present,Our country Tobacco Enterprise is faced the intense market competition, the traditional service has been receiving a more stern test; At the same time, 21st century market competitions mainly are the product quality competitions, the enterprise fine refinement control level competition must survive the development in the competition, raises the enterprise modern management level, establishes the perfect enterprise information system is enhances the enterprise competitive power the important measure.The SPC technology already extremely was in recent years widespread in the overseas application, already became enhances the business management the effective tool, passed"SPC"the method utilization statistics technology to carry on the monitoring to in the production process various working procedures parameter, discovered the process exceptionally was prompt reports an emergency,thus achieved the guarantee product quality and produced the fine refinement the goal.But at present"SPC"mostly only pauses in the domestic tobacco enterprise's production process application in the production scheduling and in the statistical data analysis in the scene monitoring,with afterwards data display; Moreover majority of also pauses in uses the MiniTab software, or using Excel in the form some simple SPC statistics function,only can carry on afterwards analysis and processing,the data processing lag also the efficiency is low,cannot achieve the real-time monitoring.First, this thesis analyzes Cigarette Factory in the enterprise informationization construction present situation and introduces the SPC theory. The content and meaning of the research subject is expounded.Second, based on the frame of the system constructed, all hareware-parts of the system are analyzed.Third, combined with the application of SPC in the practical production, the reqirements of system is analyzed, the data mining module is built up and the performance of the data acquidition is simulatied.Though tested it , the system is feasible. It can eliminate unusually, the recovery procedure stability and the enhancement production management.In the end, it draws some conclusion and gives some expection.
