| 6sigma management method were applied in the Motorola and GE, which achieved a lot ofbenefits at lst. So,6sigma management method is gradually known by people, and then spreadto all over the world at present, and it is accepted by numerous excellent large companies andwidely application. Finally all of them have made continued success. Application of6sigmamanagement method in corporations for China began in the1990s. It was used to improve thequality of management and production efficiency and eventually to improve enterprise corecompetitive ability in industry.The quality and efficiency of productivity are the mainly two core competitive factors ofmanufacturing enterprises. Through the summary of six sigma application experience andmethods, it can be found that6sigma is often used to overcome the product quality problemsand difficulties in production, but the study on six sigma applying in improving productionefficiency is relatively rare. As a result, the6sigma should be combined with production linebalance method. It can bring the benefits of the three aspects:1) increasing the stability of thequality of the product production;2) reducing the unqualified product variability;3) increasingrevenue (efficiency gains).For the study of this article, it analyzes the Chinese manufacturers of6sigma managementapplication in difficulty, then, it will work with the reality of the actual situation of a company. Itmainly researched the method of six sigma application in the production of a product model ofbulldozer and assembly process, and focused on six sigma method for production of assemblyline balance and optimization, to enhance assembly efficiency on the premise of guaranteequality.Specific process is as follows:1) In carding machine assembly and production present situation and on the basis of theoverall requirements of the order, Y (6sigma project objectives) was generated.2) The per capita and scope of160type bulldozer were enhanced, project team wasestablished, and the expected financial was gained.3) Relevant data collection plan was prepared, the IP0flow diagram was listed and fishbonediagram can present factors and factor is more intuitive.4) Through six sigma tools commonly used PLATO (PLATO chart), histograms and SODanalysis, it indicates that the main process affecting the production efficiency, effectively controlsection location, location, distribution of the material and method and so on.5) Establishing the real-time monitoring program for supervision and administration ofproduction and process, and on this basis, the production data of real-time monitoring on site wasanalyzed. Using optimization method, line balance rate analysis and material analysis and othermethods to improve the key factor to Xs. Ultimately the goal of improvement of the productionefficiency was achieved. 6) At last the final financial benefits were achieved, and the research achievementsmentioned above were changed into related management process, to provide guarantee for futureapplication. |
