Research On N Company Assembly Line Planning And Follow-up Improvement

China’s wind power industry is not only a world leader in terms o f scale but a lsocatch up with the world’s advanced leve l on the technical strength, the future cancontinue to rely on the domestic stability of the market pull, Chinese wind power willlead the develop ment of the global wind power industry. In the next stage of thecompetition, the focus is not techno logy, but should be―so ft power‖of enterprises,inc lud ing advanced forms of production orga nization and quality assurance of highreliability. Therefore, as bus iness mana gers should consider how sc ientific andeffective mana ge ment o f the wind turb ine productio n process to meet market demandand to ensure qua lity and reliab ility, which will become the focus of the next stageof contest between the ma nufacturers.For the wind turb ine ma nufacturers, technically assemb ly line production can beachie ved, but because of the wind power industry has just star ted in China, manycompa nies are not the large-scale production, as well as wind power industry has thestrong cyc lica l characteristic lead to corporations has yet to imple me nt assemblylines. But with the pace of wind power industry by leaps and bounds, when facing thesuddenly panic orders, assembly line production mode l rema ins the most effectiveway to solve the wind turb ine manufacturing situation.In this thesis, based on a wind turb ine manufacturing company, according to itsproductio n status, ana lyze and eva luate feas ibility o f the proposed assemb ly line. Thepaper concentrates on the p lanning a nd designing process of the corporate assemblyline, inc luding organizationa l des ign and technica l design. Organizationa l des ignfirstly pred ict the future productio n tasks, calculated the annua l production a nd who lework ing time in the future, acquired the takt time. Make the existing process changeto an integer multip le of takt time or equa l to takt time, required the partitio ningresults; The technical des ign of the line inc lude the equipme nt and production linelayo ut planning process. After the imp le mentatio n of the assemble line, it happen theproble m of imbala nce of the line and the shortage of home made materia l, then itsimprove ment process will be put forward.To analyze and improve the use of industria l engineering methods for theassemb ly line balance proble m, first o f a ll through the ho urs of work measure ment toidentify the bottleneck station, to ana lyze the bottleneck station, use o f joint operations for a three-position ana lys is to improve the optimization of the fourworkers carried Learning Curve ana lys is, the e ight-station hand ling processoptimizatio n, and eventua lly e liminate the bottle neck station to reach the ba lance ofthe production line.The ho me made products alwa ys ha ve lots of proble m, if use the conve ntiona lforecasting methods do not reflect the accuracy of the forecasts, it is proposedMarkov forecasting methods for modeling and analys ing, the first collectio n of100days the qua lity of data for statistical a nalys is, statistica l data into the optima l state,intermediate state and refused to state, and100sets of data correspond to therespective state statistics between the number of state trans ition, and fina lly get thestate trans ition probability. Using the state trans ition probability ca n be to predict thequality status of the fo llow-up ma nufacturing to make the productio n line staff inadvance to take measures to cope with the occurrence of qua lity defects, reducing theoccurrence of qua lity defects and the lack of materia l phenome na of the assemblyline.
