Research On Applying Of Six-Sigma In Liquid Crystal Display Product Cost Improvement

Following the aggravation of the market competition, the competition that enterprises are facing is becoming fiercer. Enterprises should survive, develop, that must pay attention to the management to the cost of the products. Taking every measure to reduce the cost, enterprises carry on the production management. This text passes analysis to Liquid Crystal Display's production cost, designs the control system method of 6Sigma in production cost, in order to help the company to find the route to reduce effectively the production cost.First, discusses the common enterprise production cost, and put in the care of enterprise using common Activity-Based Costing, 8D Method and Lean Production to improve the production cost of limitations, and detailed comparison method about the Lean Production, 8D method and 6Sigma.Second, combining 8D method, established the system model of 6Sigma to improve production cost. The system framework includes the framework of production cost to improve, activities INTOTHE key stages, and detailed implementation steps and goals of Define Phase, Measure Phase, Analyze Phase, Improve Phase and Control Phase.Finally, using the system model of 6Sigma to improve Liquid Crystal Display's production cost, Production cost saving effect is remarkable.
